Tech Lead / Lead Backend Engineer | Python & Agentic AI
Salary: up to £130,000 + Equity
Location: 1 day in London
We're partnering with a leading UK fintech that's looking for a hands-on Tech Lead to take ownership of a core customer-facing platform.
The business is helping small and medium-sized companies access the funding they need to grow, combining technology, data and financial services to make lending faster, simpler and more accessible.
This is a great opportunity for an experienced Senior Software Engineer looking to step into leadership, or an existing Tech Lead who wants to stay close to the code while having genuine influence over architecture, product decisions and engineering practices.
Why This Role?
- Genuine technical ownership: Take the lead on architectural decisions and modernising a business-critical platform, including breaking down a legacy monolith into independent backend services.
- Stay hands-on: Spend the majority of your time designing and building software, working closely with Product, Data Science and Credit Risk on real customer and commercial challenges.
- Shape AI engineering practices: Help drive the adoption of agentic engineering workflows, AI coding agents and AI-assisted software development across the team.
- Grow as a leader: Initially manage and mentor two engineers, with the opportunity to influence hiring and team growth.
Responsibilities for Tech Lead
1. Strong Backend Engineering: Experience building and scaling production systems using Python, Django, Java, C#, Kotlin or another object-oriented language, with solid software architecture and system design skills.
2. Technical & People Leadership: Experience leading engineers, making architectural decisions and mentoring or line managing others, while remaining hands-on.
3. Agentic AI Engineering: Practical experience with AI-assisted development and agentic workflows, ideally having introduced AI engineering principles, coding agents or new ways of working within a software engineering team.
If you're a Tech Lead, Lead Software Engineer or Senior Backend Engineer who enjoys building great software, influencing technical direction and exploring how agentic AI can transform engineering teams, we'd love to hear from you.
