Artificial Intelligence Engineer

Build production AI systems that solve real-world problems.

An ambitious, venture-backed startup is looking for an experienced AI Lead to take ownership of the company's AI strategy and technical direction. This is an opportunity to join early, shape the architecture from day one, and build production AI systems that have a genuine impact.

This role is focused on agents, not prompts.

The successful candidate will:

• Own the company's AI strategy and technical direction.
• Design and build production-ready agentic AI systems for complex, multi-step workflows.
• Build beyond traditional RAG using tool calling, structured outputs, orchestration frameworks and multi-agent systems.
• Develop robust evaluation, testing and feedback frameworks.
• Deliver reliable AI systems with a focus on latency, scalability, observability, cost and resilience.
• Transform complex, manual workflows into deterministic and auditable AI-driven systems.
• Research, evaluate and implement state-of-the-art AI technologies where they create meaningful value.

What they're looking for

• Strong Python backend engineering experience.
• Excellent knowledge of FastAPI, data structures and modern backend infrastructure.
• Proven experience building production LLM applications using complex agent-based architectures.
• Experience leading technical decisions around LLMs, SLMs and model fine-tuning.
• Strong understanding of evaluation frameworks, observability and production reliability.
• Solid machine learning and NLP fundamentals.

Tech Stack

Python • FastAPI • LangGraph • PostgreSQL • Vector Databases • GCP • Docker

This is a genuine Start-up.

Please read this section before applying.

This is not a corporate environment with predictable 9-5 hours and clearly defined responsibilities.

The team moves quickly, priorities evolve rapidly and everyone is expected to take ownership beyond their job description.

There will be periods where you're working late to solve difficult problems, hit important milestones or launch new products. If your expectation is to leave the office at 6pm every day regardless of what's happening, this role is unlikely to be the right fit.

In return, you'll have an exceptional level of ownership, influence and autonomy. You'll work directly with the founders, help shape the company's AI strategy and have the freedom to experiment with cutting-edge technologies without layers of bureaucracy.

This is an opportunity for someone who thrives in an early-stage environment, enjoys solving difficult technical challenges and wants to build something from the ground up.

Why join?

• Shape the AI strategy of a fast-growing startup from an early stage.
• Build production AI systems that solve genuinely difficult problems.
• Work directly with founders and senior leadership.
• High levels of autonomy and technical ownership.
• Freedom to research, experiment and implement state-of-the-art AI technologies.
• Join a small, high-performing team where your work will have immediate impact.
