Head of Project Engineering
About Volta
Volta is the category-defining, fully vertically integrated AI infrastructure platform – from capital to clusters to software, under a founder-led enterprise. Our mission is The Utility of Compute™: AI infrastructure as dependable and available as electricity, for every organization that needs it. Launched with a $10B strategic partnership with one of the leading frontier AI labs, a Series A led by Andreessen Horowitz, and a $5B AI Infrastructure Fund, Volta is building the infrastructure layer of the AI era from the ground up. We are 100+ people across London, Palo Alto, and New York, with rapid growth expectations to hundreds.
About The Role
Volta builds and operates large scale GPU compute infrastructure for frontier AI customers. Every deployment is a project: a site, a customer, a hardware generation, a power and cooling envelope, a network fabric, and a date the cluster has to be producing useful work.
Our project teams own those deployments end to end. Each is roughly five senior engineers spanning data center operations, network engineering, and systems and platform engineering. They join during the discovery phase of a deal, when the technical shape and the commitments are still being formed, and stay with the project until the cluster is handed over to steady state operations.
As Head of Project Engineering you own that function. You lead multiple project teams delivering concurrently across sites, you are accountable for what Volta commits to technically during deal discovery and for whether we then deliver it, and you own the standard by which a cluster is declared done.
This is a leadership role with deep technical substance. You will not be running these deployments from a spreadsheet.
What You Will Be Doing
Deal Discovery and Commitments
Own technical input into deals from the discovery phase: site feasibility, power and cooling envelope, hardware and fabric options, deployment sequencing, and what is realistic on what timeline.
Pressure test what is being committed before it is signed. You are the person who says a date is not achievable while that is still cheap to hear.
Contribute the technical basis for cost models, bills of materials, and capacity assumptions, and make the assumptions explicit so they can be revisited when reality moves.
Support customer technical due diligence and, where relevant, lender or investor technical review.
Project Delivery
Hold accountability for delivery across a portfolio of concurrent deployments: scope, technical quality, and readiness against the committed date.
Establish the delivery model each project team follows, from facility handover through rack and stack, power on, fabric build, and burn-in to acceptance.
Own escalation. When a project is off track, you are the one who diagnoses whether it is a supply problem, a facility problem, a design problem, or a team problem, and who resolves it.
Allocate people across projects and manage the reality that senior specialists are scarce and demand is lumpy.
Own risk across the portfolio, including the dependencies that sit outside Volta.
Handover to Steady State Operations
Define and enforce what "done" means: acceptance criteria, performance validation, documentation, runbook completeness, monitoring coverage, and operational readiness.
Own the handover to steady state operations as a controlled transition with an agreed definition of complete, not a gradual disengagement.
Make sure the operational and SLA commitments Volta has made are actually supportable by what the project team leaves behind.
Close the loop back into engineering: what went wrong, what was manual that should not have been, and what needs to change in the platform or the process before the next site.
Organization and People
Build and lead the project engineering function: team leads, project engineers, and the senior specialists who make up the teams.
Hire senior technical people into a role that requires travel, ambiguity, and site presence, and be honest with candidates about what that involves.
Run the management basics properly: 1:1s, performance conversations, development, and succession for a function where key person risk is real.
Establish a career path for project engineers so that the role is a destination rather than a rotation people try to leave.
Partners and Vendors
Own the technical relationship with OEMs and integration partners through delivery, including holding them to their commitments.
Work with facility and colocation partners on demarcation, handover, and the boundaries of who owns what physically and operationally.
Manage partner-delivered scope where deployments use external field services or managed services capacity.
Standards and Repeatability
Turn deployments from bespoke projects into a repeatable process. The second site should be materially easier than the first, and the fifth should not need you in the room.
Own the reference deployment model, standard acceptance test suites, and the documentation set every project produces.
Work with platform and network engineering so that what the project teams do by hand today becomes automated tomorrow.
What You Bring
8+ years in data center, infrastructure, or large scale technical delivery, with at least 3 years leading multiple teams or leading through team leads.
Track record delivering large scale compute deployments end to end, at a scale where power, cooling, and logistics are constraints rather than details.
Real technical depth in at least two of: data center facilities and power and cooling, high performance network fabric, or compute and systems engineering. Enough credibility in the others to lead senior specialists who know more than you do about their own area.
Familiarity with GPU cluster deployment: rack scale systems, high density power, liquid cooling, and the acceptance and validation work that proves a cluster is fit for training workloads.
Experience owning delivery against commercial commitments, where dates and acceptance criteria have contractual and financial consequences.
Multi-vendor OEM and partner management under delivery pressure, including holding vendors to schedule and quality without breaking the relationship.
Experience running concurrent projects with shared, constrained specialist resource.
Comfortable in commercial conversations: contributing to deal shaping, feasibility, and cost basis, and translating technical constraints for commercial and customer audiences.
Willing and able to travel to sites and partner locations regularly, including during critical delivery phases.
Clear communicator who can hold an uncomfortable position with senior stakeholders and customers when the technical reality requires it.
Nice to Have (But Not Essential)
None of these are required.
Experience with NVIDIA reference architectures and rack scale systems, and with the certification and validation process that comes with them.
Direct liquid cooling deployment experience, including CDU integration and facility demarcation.
Background at a neocloud, hyperscaler, HPC center, or specialist data center integrator.
Experience deploying in the Nordics or in sites with unusual power, climate, or grid characteristics.
Exposure to technical due diligence for lenders or investors on infrastructure projects.
Familiarity with structured delivery frameworks, and a clear view on where they add value and where they become overhead.
Experience introducing automation or tooling into a delivery function that previously ran on people and spreadsheets.
Fluency with AI-assisted workflows for planning, documentation, and reporting.

About Volta
Volta is the category-defining, fully vertically integrated AI infrastructure platform – from capital to clusters to software, under a founder-led enterprise. Our mission is The Utility of Compute™: AI infrastructure as dependable and available as electricity, for every organization that needs it. Launched with a $10B strategic partnership with one of the leading frontier AI labs, a Series A led by Andreessen Horowitz, and a $5B AI Infrastructure Fund, Volta is building the infrastructure layer of the AI era from the ground up. We are 100+ people across London, Palo Alto, and New York, with rapid growth expectations to hundreds.
About The Role
Volta builds and operates large scale GPU compute infrastructure for AI workloads. The network is not a layer underneath our platform, it is part of it. Fabric design, overlay and multi-tenancy, edge connectivity, and the software that programs and observes all of it sit in one platform engineering team, deliberately.
This is a network role with a software expectation attached. You will need real depth in fabric and routing, because a 20,000 GPU training cluster punishes anyone who understands the network only from documentation. You will also need to write production code, because at this scale anything that requires a human at a CLI does not happen reliably. Configuration is generated from a model, validated in CI, and applied by tooling. If your current work is mostly logging into devices and making changes by hand, this role will be a significant shift.
You will work alongside platform engineers, not adjacent to them: same repositories, same review standards, same definition of done.
What You Will Be Doing
Common across the team:
Design, build, and operate the network fabric across our sites: leaf-spine Ethernet, BGP underlay, EVPN and VXLAN overlay, and multi-tenant isolation.
Build and extend the software that manages the fabric: configuration generation from a source of truth, validation pipelines, drift detection, and the tooling that makes change safe at scale.
Contribute production Python or Go to the platform codebase, including the integration between the physical fabric and the IaaS control plane.
Own how network capability is exposed upward: the APIs and abstractions through which tenants receive isolated, performant networking.
Instrument the fabric: streaming telemetry, topology-aware metrics, and tooling that makes a fabric of this size understandable.
Work with the bring-up teams during cluster deployment: fabric build, validation, acceptance testing, and turning the pain points you find into platform features rather than tribal knowledge.
Debug the hard problems: congestion and packet loss under collective communication load, and the class of failure where controller state and hardware state disagree.
Take part in on-call, incident response, and the follow-up work that closes structural gaps rather than only the immediate issue.
Evaluate designs and configurations proposed by OEMs and partners, and challenge them where they do not fit our requirements.
Participate in code review, technical design discussions, and cross-team collaboration in an Agile (Kanban or Scrum) environment.
Depending on your background, you will go deeper in one of these areas:
GPU fabric: RoCE v2 and InfiniBand for training traffic, congestion control tuning, rail-optimized topology, and the performance validation that proves a cluster is fit for workloads.
SDN and overlay integration: the software boundary between the fabric and the platform, controller and API-driven fabric programming, and multi-tenant network provisioning.
Edge connectivity: external connectivity, BGP peering, transit and IX relationships, and our public autonomous system.
Fabric observability: telemetry pipelines, fabric health tooling, and making network state queryable rather than inspectable.
What You Bring
4+ years in data center or cloud network engineering, in production environments where downtime had real consequences.
Ethernet fabric depth: leaf-spine design, BGP including unnumbered BGP, ECMP, and the day-two realities of operating it.
EVPN and VXLAN in production, including what happens to an overlay under multi-tenant load.
Production software development, not scripting. Python or Go in a shared repository, under normal review, testing, and CI standards. Tools only you can run are not what we mean.
Network automation in practice: configuration as code, a source of truth system such as NetBox or Nautobot, and declarative or idempotent workflows.
Solid Linux fundamentals and comfort at the command line as an engineer, not only as an operator.
Familiarity with Kubernetes networking and how workload networking interacts with the underlying fabric.
Multi-vendor capability. Able to work across major OEM platforms and not dependent on one vendor's CLI.
Willing to be on site during cluster bring-up when it matters.
Clear written communication. Designs, decisions, and failure analysis need to be readable by people who were not in the room.
Nice to Have (But Not Essential)
None of these are required. Several map to specific areas of the team's scope, so strength in one or more helps us place you well:
Fluency with AI-assisted development: agentic CLI tools, IDE assistants, and orchestrating multiple coding agents through MCP, skills, or APIs to amplify delivery.
RoCE v2 at scale: PFC and ECN tuning, DCQCN, and how it behaves differently from InfiniBand under training load.
InfiniBand production experience: fat tree topology, UFM, fabric partitioning, adaptive routing, and SHARP.
NVIDIA Spectrum-X, including NetQ and Cumulus, or SONiC and whitebox platforms.
gNMI, OpenConfig, or NETCONF and YANG for configuration and telemetry.
IPv6 at production scale: dual stack design, v6 BGP peering, and addressing architecture.
ASN operations: public autonomous systems, transit and IX peering, RPKI and IRR hygiene, and DDoS posture.
OVN and OVS, SR-IOV, DPDK, or BlueField DPU based networking.
Network simulation or emulation with containerlab, NVIDIA Air, or equivalent.
Familiarity with NVLink and NVSwitch topologies and NCCL behavior.
Depth in Go or Rust beyond working proficiency.
Open source contributions to networking or infrastructure projects.
Experience working distributed across time zones with counterparts in other regions.
