Senior Python Engineer

🚀 Senior Python Engineer – AI & Agentic Systems | London | £100k

Build production AI agents

I’m working with a high-growth, technology-led business that is investing heavily in AI and looking for a Senior Python Engineer to help build the next generation of its engineering platform.

This is not a traditional Data Science or ML role .

You’ll be a hands-on software engineer building production-grade Python services, APIs and AI-powered systems , with real ownership over architecture, infrastructure and delivery.

🤖 What you'll be working on

You’ll help build and scale an agentic AI platform that brings AI into real business workflows, with a strong focus on security, reliability and engineering quality.

You’ll be involved in:

🔹 Building production Python services and APIs

🔹 Designing and integrating LLM-powered applications and AI agents

🔹 Agent orchestration, tool calling and RAG

🔹 Authentication, permissions and AI guardrails

🔹 Evaluation, monitoring and observability

🔹 Cloud infrastructure and deployment

🔹 Terraform / Infrastructure-as-Code

🔹 Docker, CI/CD and production engineering

🔹 Using tools such as Claude Code, Cursor or similar

🔹 Helping shape how AI is adopted across the wider engineering team

🧠 What we're looking for

We're looking for a strong software engineer first , with genuine experience building with AI.

You'll ideally have:

✅ Strong commercial Python experience

✅ Senior-level backend/software engineering experience

✅ Experience building APIs, services or microservices

✅ Production experience with LLMs, GenAI or AI agents

✅ Experience with RAG, tool calling, LangChain, LangGraph, MCP or similar

✅ Hands-on Terraform / IaC experience

✅ AWS or Azure experience

✅ Strong understanding of testing, security and production systems

✅ Experience using AI coding tools such as Cursor or Claude Code

Most importantly, we're looking for someone who has actually built and shipped AI-powered systems , rather than someone whose AI experience is limited to experimentation.

🌟 Why join?

This is a genuine opportunity to have a major influence on how AI is used across an engineering organisation .

You'll have ownership over technical decisions, work on production agentic systems and help shape the standards around security, deployment and AI-assisted development.

💰 £100k + benefits

📍 London – 3 days per week

💼 Permanent
