You will operate the Product Security programe for Blockchain.com’s internally-developed products across Consumer, OTC and MRE lines. This is a senior, hands-on role: you’ll design and run the secure development lifecycle, lead threat modeling and architecture review, own the security debt lifecycle for product engineering teams, and architect the automated pipelines that protect billions in transaction volume. You will embed with product and engineering teams, convert technical findings into business-prioritized remediation, and lift developer capabilities so security is delivered by code and process.
WHAT YOU WILL DO
Strategic Security Partnership: Act as a senior security engineer for the different product lines like Consumer, OTC. You will own the security gates for major feature releases and ensure security is integrated from the design phase.
Secure SDLC Operator: Operate and improve the secure development lifecycle. This includes orchestrating SAST/SCA/DAST, streamlining SARIF ingestion, PR review standards, CI/CD security automation, and vulnerability triage workflows.
AI-Driven SDLC Innovation: Research, architect, and safely embed cutting-edge AI utilities and Large Language Model (LLM) agents directly into our secure development lifecycle.
Threat Modelling & Architecture Reviews: Lead STRIDE/attack-tree threat models for sensitive flows including authentication, payment, custody, reconciliation and sign off on security architecture for critical designs.
Product Security Governance & Standards: Translate technical risks and regulatory demands into clear security policies. You will own the creation and upkeep of our Application Security Standards, reference architectures, and compliance-driven secure coding baselines.
Bug Bounty Leadership: Oversee the technical triage and remediation strategy for our Bug Bounty program. You will turn external researcher findings into internal architectural hardening projects.
Release Reviews: Perform deep-dive manual code reviews of security-sensitive Pull Requests, mentor engineers on secure coding patterns, and provide pragmatic remediation guidance.
Advanced Code Auditing: Conduct deep-dive manual and automated code reviews on highly sensitive Java and Kotlin backend Pull Requests.
Security Debt & Remediation Negotiation: Produce data-driven Security Debt packs and negotiate remediation into engineering roadmaps. You will negotiate remediation timelines with Product Owners and Engineering leadership, backed by risk-based data.
Detection & Telemetry Integration: Define application runtime signals (business-logic anomalies, auth anomalies, reconciliation mismatches) and work with SecOps to instrument logs and alerts.
Testing & Automation: Build and maintain product-level test harnesses, fuzzing/property tests and CI checks to prevent regressions for business-critical flows.
Incident Response Support: Provide product-level Incident Response expertise like test forensic runbooks, support reproduction of payment/settlement incidents, and advise on containment/remediation whenever needed.
Metrics & Risk Visibility: Define and own the Product Security metrics (e.g., MTTR for critical vulnerabilities, security debt burn-down, and defect density). You will translate these KPIs into high-level risk reports for the Head of Security and Engineering leadership to drive data-backed resourcing decisions.
People & Process: Coach junior product security engineers and security champions. You will assist the Product Security Lead to define hiring standards and capability plans.
WHAT YOU WILL NEED

You’ll be the hands-on security engineer embedded with the Institutional Trading and Financial Operations (FinOps) team. Your focus is the secure operation of off-chain trading processes and infrastructure that empowers our institutional business: integrations, signing flows, key custody interfaces, middle-office workflows, order routing and settle pipelines that handle significant capital. You will support risk assessments, operating controls, automation to detect operational anomalies and remediation coordination. This is a high-visibility role where you will focus on operational security engineering - ensuring that the tools and processes our traders use are resilient against both external threats and internal errors.

Conduct deep-dive assessments mapping critical assets and workflows to identify structural vulnerabilities. You will be responsible for defining the Target State and drafting the strategic Risk Treatment Plans (RTP) required to meet institutional-grade standards (e.g., CCSS, NIST, DORA).
Act as the primary security liaison for Senior Management and third-party vendors. You will translate complex technical gaps into actionable business risk summaries, drive vendor evaluations for core security infrastructure, and manage the project lifecycle for high-impact posture uplifts.
Implement and maintain monitoring for FinOps-specific security signals such as abnormal order patterns, signature misuse, unusual settlements. You will integrate these signals into our SIEM/SOAR for real-time response.
Support secrets and key-management hygiene. You will ensure app/service keys are stored in KMS/Vault, scoped to least privilege and rotated automatically to prevent credential leakage.
Assist product security in triage of SAST/SCA findings for FinOps-related repositories. You will help implement CI checks and remediation playbooks.
Participate in incident exercises, post-incident reviews and remediation tracking for trading incidents.
Document controls and produce concise risk summaries for FinOps leads and the Security.
AI-Driven Innovation: Research, architect, and safely embed cutting-edge AI utilities and Large Language Model (LLM) agents directly into our secure infrastructure.
WHAT YOU WILL NEED
5+ years in security engineering, platform security, or application security experience.
Proven expertise in Threat Modeling. Ability to perform structured reviews (e.g., STRIDE) of complex data flows and operational processes.
Experience with observability and detection tooling (SIEM, logs, metrics) and ability to write basic detection rules.
Practical experience with KMS/HSM, secrets management platforms (Vault, 1Password, AWS/GCP KMS), IAM patterns and least-privilege.
Exceptional ability to translate "Technical Debt" into Business Risk for C-suite stakeholders (CFO, CTO, Head of Trading).
Ability to raise, read and audit Pull Requests in at least one language used in our stack (TypeScript, Java/Kotlin, Python).
Experience conducting technical due diligence and scoping for third-party security integrations.
NICE TO HAVE
Familiarity with trading systems or financial operations (market-making, execution, settlement) or close collaboration background with trading/quant teams.
Exposure to blockchain on-chain concepts (wallets, addresses, transactions) but no requirement to audit contracts.
Familiarity with SOC operations, and post-incident forensic analysis.
Familiarity with SOC2, ISO 27001, or financial audit requirements
Any relevant industry certification
