Job Description:

AI Tech Lead – Agentic AI, LangGraph, ML, Python, CI/CD, LLM’s, Early-Stage Startup, UK Remote

About the Role

A mission-driven, early-stage startup is looking for an AI Tech Lead to join its growing team. This is a hands-on leadership role where you’ll help shape a cutting-edge AI platform designed to drive real-world behaviour change and improve human performance and wellbeing.

Backed by strong funding, this product-focused team of senior engineers operates in a low-ego, high-collaboration culture. The platform's first focus is on employee wellbeing in high-stress industries—and the mission is just getting started.

You’ll lead a cross-functional team of backend and machine learning engineers, guiding architecture, mentoring team members, and staying close to the code. This is a rare opportunity to build both product and team in a fast-moving environment with purpose at its core.

What You’ll Do

• Lead and mentor a senior engineering team working across backend, ML, and infrastructure.
• Play a key role in design, development, and deployment of AI applications using LLMs, Agentic framework, and other related technologies.
• Own technical direction for core systems, focusing on scalability, performance, and reliability.
• Write clean, maintainable code and contribute actively to the codebase.
• Define and uphold engineering best practices (code quality, CI/CD, observability, etc.).
• Collaborate closely with the CTO and product team to align technical delivery with strategic goals.
• Continuously improve team operations, development workflows, and developer experience.
• Play a key role in hiring and onboarding as the team grows.

What We’re Looking For

• 7+ years of commercial software engineering experience with a strong backend focus.
• Proven ability to lead engineering projects and/or teams.
• Experience with LangGraph, and a good understanding of agentic patterns (e.g. self-reflection, prompt/response-optimisation, multi-modal guardrails, cross-reflection, role-based cooperation).
• Hands-on experience in launching GenAI products, including agentic systems and multi-agent frameworks, driving real-world AI applications from concept to deployment.
• Experience in fast-paced or startup environments.
• BSc in Computer Science, Data Science, or related technical discipline.
• Strong communication skills and a bias toward action.

Technologies You’ll Work With

Experience in some or most of the following:

• Languages/Frameworks: Python, FastAPI, Pydantic, Streamlit (for internal tools).
• AI: AgenticFlows, GenAI, LLMs, and multimodal systems.
• Infrastructure: Docker, Terraform, GitHub Actions, GCP (preferred).

The role is remote with occasional travel.
