[Hiring] Lead Software Engineer (Frontend) Fleet @Job Board

Role Description

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.

• 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.

Qualifications

• 8+ years of professional software development experience, with a definitive track record in senior, staff, or lead frontend engineering roles.
• Elite-level expertise in TypeScript, React, and the modern frontend ecosystem (advanced state management, build tooling, and modular architecture).
• Proven experience building, maintaining, or significantly scaling an enterprise-grade design system or shared component library.
• Strong experience consuming REST and GraphQL APIs to power data-heavy interfaces, with comfort parsing formal specifications like OpenAPI.
• Deep familiarity with modern testing frameworks across unit, component, and end-to-end (E2E) automation layers to prevent production regressions.
• A verified commitment to building inclusive, WCAG-compliant accessible user interfaces.
• Extensive experience collaborating alongside UX designers, product managers, and backend engineers.
• Bachelor's degree in Computer Science, Software Engineering, or a related technical field (or equivalent enterprise professional experience).

Requirements

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

Benefits

• The compensation for this position may vary depending on factors such as your location, skills and experience.
• Depending on the nature and seniority of the role, a percentage of compensation may come in the form of a commission-based or discretionary bonus.
• Equity and additional benefits will also be awarded.
• Compensation Range: $170,000 — $220,000 USD.
