Technical Lead

Technical Lead

London / Hybrid

£110-130k

The opportunity

This is a rare chance to lead technically without stepping away from the code. You'll set the technical direction for a small, ambitious engineering team, working alongside the Director of Engineering to turn product goals into pragmatic designs and carry important work through to production. It's a hands-on role built on influence and credibility, not headcount.

What you'll be doing

Provide hands-on technical leadership from discovery and design through to implementation, release and production validation

Translate product and business goals into clear technical approaches, keeping solutions proportionate to the problem

Design, build and review software across a .NET, TypeScript and Python estate, stepping into complex or high-risk work when needed

Set and reinforce practical engineering standards across architecture, testing, security, observability and documentation

Mentor engineers through pairing, design reviews and constructive code review, broadening ownership across the team

Partner closely with the Senior Platform Software Engineer on reliability, CI/CD, GitOps and infrastructure automation

Help diagnose tricky production issues and turn them into durable fixes and useful runbooks

Champion thoughtful, responsible use of LLMs and coding agents across planning, implementation, testing and documentation

What we're looking for

Strong experience leading the technical delivery of production software while remaining a regular, credible contributor to the codebase

Sound system design judgement across APIs, distributed services, data flows and cloud native applications

Commercial experience with more than one of .NET, TypeScript/Node.js and Python, plus comfort working across unfamiliar codebases

Practical knowledge of AWS, Kubernetes and modern delivery practices, including CI/CD, GitOps and observability

A track record of simplifying systems and improving reliability without losing sight of customer value

Bonus points if you have

Experience building AI-enabled product features, RAG systems or production LLM integrations

Exposure to high-volume ingestion, queues, search, embeddings or vector databases

Knowledge of infrastructure as code, cloud cost optimisation or platform engineering at AWS scale

What's on offer

A genuinely hands-on leadership role with no direct reports and no meeting-led architecture-only remit

Hybrid working: two days a week in the office at London Bridge, London

No formal on-call rota currently in place

A team that actively encourages the use of LLMs and coding agents to work smarter, not just harder
