As a Lead Software Engineer on our Fleet team, you'll set the technical direction for the frontend that security teams rely on to operate fleets of Corelight sensors — sometimes hundreds at a time — and act on the configuration, lifecycle, and operational data those fleets produce. You'll bridge sophisticated APIs and the intuitive interfaces our customers depend on — partnering closely with our Lead Backend Engineer and a dedicated UX designer to shape an experience that lets defenders move with speed and precision. This is a role for a high-agency engineer who owns outcomes end-to-end: technical direction, frontend architecture, craft, and the user experience itself.

Specific Responsibilities:

• Drive End-to-End Frontend Architecture: Lead the technical design, implementation, and operation of the Fleet Manager UI—owning state management, data layers, module boundaries, performance tuning, and the long-term technical roadmap.
• Co-own the User Experience: Partner closely with a dedicated UX designer to define interaction patterns, refine complex data workflows, and make thoughtful product/UX trade-offs. Translate high-fidelity wireframes into accessible, performant, and delightful interfaces.
• Build for Real Operational Scale: Integrate complex REST and GraphQL APIs to power interactive interfaces that remain highly responsive when customers manage hundreds of live sensors concurrently.
• Steward the Design System: Champion the continuous evolution of our component library, ensuring consistency, reusability, and clean UI architecture across an expanding product surface area.
• Technical Leadership & Mentorship: Elevate frontend engineering standards through architectural guidance, rigorous code reviews, and the promotion of clean, maintainable code. Play a key role in frontend hiring, interviewing, and onboarding to scale the team.
• Leverage AI-Assisted Engineering: Utilize modern AI-assisted development tools effectively to accelerate velocity while holding auto-generated code to the same rigorous quality, security, and testing standards as hand-written code.
• Security-First Engineering: Evaluate UI changes for security implications—including authentication/authorization flows, strict RBAC enforcement, XSS mitigation, and safe sensitive data handling—partnering with backend and security teams to neutralize risks.
• API Collaboration: Partner with the Lead Backend Engineer on REST and GraphQL contract designs, utilizing OpenAPI specs to ensure frontend and backend architectures evolve in lockstep.
• Operational Excellence: Own features completely from design to production by embedding automated test suites, CI/CD pipelines, performance budgets, and web accessibility checks directly into the core workflow.

Knowledge/Skills/Abilities needed to be successful:

• Core Values Alignment: You natively embody "low ego results," "tireless service," and "applied curiosity" in your daily engineering practices and team interactions.
• Product & User Empathy: You are passionate about building interfaces that simplify dense, complex data representations into intuitive workflows for security defenders.
• Systems Thinking: You look beyond isolated components to understand how state, data flow, and frontend architecture tightly integrate across a massive, enterprise-scale application.
• Decisive Problem Solving: You comfortably navigate ambiguity, balance conflicting technical constraints, and make rapid, high-impact architectural decisions.
• Strategic Communication: You possess strong written and verbal communication skills used to influence product direction, align distributed teams, and articulate technical trade-offs clearly.

Qualifications/Requirements:

• Professional Experience: 8+ years of professional software development experience, with a definitive track record in senior, staff, or lead frontend engineering roles.
