Senior Frontend Engineer – GenAI

ABOUT THE ROLE

We’re a cybersecurity company building a next-generation generative AI platform used across multiple product surfaces – from analyst workflows to internal operations tools. We’re looking for a Senior Frontend Engineer with a strong frontend focus to design, build, and scale intuitive, high-performance experiences for data-heavy, real-time use cases.

You’ll work across the stack (with emphasis on the web frontend) to turn advanced AI capabilities – reasoning, retrieval, and automation – into trustworthy, efficient user experiences. You’ll collaborate closely with design, product, and AI/ML teams to ship features that improve investigation speed, streamline operations, and elevate customer outcomes.

• Own end-to-end delivery of user-facing features across investigative, assistive, and summarization surfaces – from proof-of-concept to launch and iteration.
• Design interactive dashboards, timelines, and graph/entity views that handle high-volume, streaming data with intuitive drill-downs and filtering.
• Build resilient real-time UX (e.g., Web Socket/SSE) and a scalable state architecture for conversations, incidents, and tickets, with reliable cross-view synchronization.
• Define clear API/data contracts, contribute to backend endpoints as needed, and integrate enterprise systems (ticketing, knowledge bases, telemetry/observability, workflow tools).
• Implement trustworthy AI UX: streaming responses with citations, guardrails/redaction, and human-in-the-loop review; capture feedback to improve prompts and behaviors.
• Instrument and improve outcomes – latency, error rates, summary accuracy, and user satisfaction – to reduce time-to-response and time-to-resolution.

• Work closely with backend, AI, product and design teams to translate complex requirements into elegant UIs.
• Mentor engineers, lead design reviews, and evolve coding standards and best practices.
• Communicate tradeoffs and architecture decisions clearly to technical and non-technical stakeholders.

• 5+ years of professional frontend development experience (full-stack a plus).
• Track record of shipping complex, data-intensive web applications at scale.
• Experience operating in high-availability, security-sensitive or support‑critical environments.
• Demonstrated ownership from architecture through delivery.

• Expert proficiency with modern JavaScript/Type Script and a component-based web framework (e.g., React).
• Experience with server‑rendered web apps and routing.
• Strong grasp of state management patterns (e.g., state containers, signals, or equivalent).
• Proficiency with async data fetching and caching for server state (e.g., query/fetch layers).
• Advanced CSS skills (responsive layouts, design systems, accessibility).
• Experience with real‑time transports (e.g., Web Socket, Server‑Sent Events) and streaming UX.
• Git‑based workflows and CI/CD; feature flagging and progressive delivery.
• Comfort with charting/graph visualization libraries and building interactive, drill‑down dashboards.
• Understanding of UX for dense, high‑stakes, data‑heavy applications.
• Experience working within and evolving component libraries/design systems.

• Excellent written and verbal communication.
• Strong problem‑solving skills and attention to detail.
• Self‑directed, collaborative, and comfortable with ambiguity in fast‑moving contexts.
• Experience working with distributed teams.

• Experience designing APIs (REST/Web Socket) and integrating with event streams.
• Comfort with at least one server runtime/language (e.g. Python, Golang) and data storage paradigm (e.g. Postgres, Neo4j).
• Understanding of authentication/authorization patterns and session management.

• Built user experiences for generative AI features (assistive workflows, agent‑style tool use, or similar).
• Understanding of LLM streaming patterns, tool orchestration, and structured outputs (citations, functions).
• Familiarity with retrieval‑augmented generation,…
