Lead software engineer

Lead Software Engineer

Lead the technical direction of AI‑native product development – owning architecture, raising engineering standards, and helping the team ship with confidence. You bring strong full‑stack depth, a pragmatic mindset, and the ability to grow the engineers around you.

What You’ll Do

• Technical Leadership – Own key architecture decisions across backend, AI, and frontend, communicate trade‑offs clearly and drive them to closure. Set and uphold engineering standards: code quality, testing, observability, and delivery practices. Identify technical risk early and propose practical paths forward. Stay hands‑on – lead by example through code, review, and design.
• Engineering Design & Build – Build scalable backend services and AI‑powered features end to end. Architect LLM integrations, RAG pipelines, and data flows that work reliably in production. Build frontend experiences that surface AI capabilities intuitively. Champion test‑first development, observability, and automated delivery.
• People & Collaboration – Mentor and grow engineers through review, pairing, and honest feedback. Partner with product and other teams to align technical work with business outcomes. Lead design discussions and help the team make good decisions faster.

What We’re Looking For

• Technical Depth
  • 8+ years of full‑stack engineering experience, with a track record of shipping production systems.
  • Comfortable across backend services, APIs, and modern frontend development.
  • Experience building and shipping AI or data‑intensive features in production.
  • Solid grasp of software design principles, distributed systems, and delivery practices.
  • Hands‑on with CI/CD, containerisation, and production observability.
• Leadership
  • Track record of owning technical strategy and driving outcomes – not just executing tasks.
  • Experience mentoring engineers and raising the bar across a team.
  • Clear communicator: can translate complexity for both technical and non‑technical audiences.
• Backend & AI
  • Python; strong async, Pydantic, and API design.
  • FastAPI in production; RESTful and event‑driven patterns.
  • Redis – caching, pub/sub, task queues (Celery / RQ / ARQ).
  • LangChain or similar; RAG: chunking, embeddings, retrieval.
  • Prompt engineering; hands‑on with OpenAI, Claude, or Gemini.
  • Vector stores: Pinecone, pgvector, or equivalent.
• Frontend
  • React with hooks, context, and TypeScript.
  • Streaming UI patterns – SSE, WebSockets.
  • Component testing with React Testing Library / Vitest.
• Delivery & Quality
  • CI/CD with GitLab or equivalent; Docker; Kubernetes or ECS familiarity.
  • TDD mindset – pytest and Jest/Vitest, coverage gates enforced in CI.
  • Observability: OpenTelemetry, Grafana, or similar.
