Primary Responsibilities
- Define and own the full-stack architecture (frontend, backend, APIs, data layer) for the agentic AI platform's UI and supporting services
- Establish design patterns for building responsive, real-time interfaces that visualize agent reasoning, multi-step task execution, tool calls, and streaming outputs
- Drive decisions on frameworks, state management, API contracts (REST/GraphQL/WebSockets/streaming), and infrastructure choices in partnership with platform/infra teams
- Ensure the architecture supports scalability, low-latency streaming (token-by-token or event-based UI updates), extensibility for new agent capabilities, and enterprise-grade security
- Build, lead, and grow a team of full-stack engineers, frontend specialists, and backend engineers (potentially across multiple pods/squads)
- Set engineering standards for code quality, testing, CI/CD, accessibility, and performance
- Mentor senior engineers and engineering managers; support career development and technical growth across the org
- Drive a culture of ownership, craftsmanship, and rapid iteration appropriate to a fast-evolving AI product space
- Partner with Product Management and Design to translate agentic AI capabilities (tool use, multi-agent orchestration, memory, planning) into intuitive, trustworthy user experiences
- Work closely with AI/ML and Platform Engineering teams to expose model/agent behavior (reasoning traces, confidence, citations, errors) in ways that build user trust and transparency
- Collaborate with UX research to iterate on interaction patterns unique to agentic systems (e.g., approvals, interruptions, plan editing, multi-turn context)
- Own roadmap planning, sprint execution, and delivery predictability for the UI/full-stack workstream
- Establish metrics for platform reliability, performance (latency, load times, streaming responsiveness), and UI quality
- Manage technical risk, tech debt, and platform scalability trade-offs as the product scales to more users, agents, and use cases
- Report progress, risks, and technical strategy to senior leadership/executives
You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.
Required Qualifications
- 10+ years of full-stack software engineering experience
- 5+ years in engineering leadership
- Solid hands-on expertise across the modern full-stack: Frontend: React/Next.js (or similar), TypeScript, state management, real-time/streaming UI patterns (WebSockets, SSE), component design systems. Backend: Node.js, Python, Go, or Java; API design (REST/GraphQL); microservices architecture
- Experience building or integrating with LLM/AI-powered products - e.g., chat interfaces, copilots, agentic workflows, RAG systems, or tool-calling architectures
- Proven experience architecting and shipping complex, production-grade web applications at scale (consumer or enterprise SaaS)
- Direct experience with agent frameworks (LangChain, LangGraph, AutoGen, custom orchestration)
- Infrastructure: Cloud platforms (AWS/GCP/Azure), containerization (Docker/Kubernetes), CI/CD pipelines
Preferred Qualifications
- MS/BS in Computer Science or related field, or equivalent practical experience
- Experience at an AI-native company or on an AI platform/tooling team
- Experience with design systems and accessibility standards (WCAG) for enterprise software
- Experience with streaming data visualization (e.g., visualizing multi-step agent plans, tool call graphs, live logs)
- Familiarity with agent observability concepts - tracing, evals, guardrails, human-in-the-loop review flows
- Background in developer tools, low-code/no-code builders, or workflow orchestration UIs
- Exposure to security/compliance considerations for enterprise AI products (SOC 2, data governance, PII handling)
- Proven excellent communication skills; ability to operate across technical depth and executive-level strategy conversations
