Overview
I’m currently working with a leading financial services technology consultancy that is looking to bring in an experienced Tech Lead to support the delivery of modern software solutions for a major pensions client. This role sits at the intersection of financial modelling and modern engineering, supporting the development of platforms used for forward-looking financial analysis, including discounted cashflow projections and Monte Carlo simulations. This is a hands-on leadership role, splitting your time between full-stack engineering and leading a team of senior developers. You’ll also play a key role in shaping AI-assisted and agentic development workflows, helping embed these approaches into day-to-day engineering practices.

The Role
You will lead a team of four experienced engineers while remaining actively involved in the development process, with a strong emphasis on Python-led development within a modern cloud environment. Alongside technical leadership, you will coordinate delivery, run Agile ceremonies, and act as a key technical contact for stakeholders and clients. The role requires someone who leads by influence, communicates confidently with clients, and brings practical experience implementing AI-assisted and agentic engineering workflows within real delivery environments.

Key Responsibilities
• Leading a team of four senior engineers within an Agile delivery environment
• Remaining hands-on with Python-led full-stack development, alongside TypeScript, React and Azure
• Contributing to platforms supporting financial modelling and forward-looking analytics including discounted cashflow projections and Monte Carlo simulations
• Championing AI-assisted and agentic engineering workflows, embedding these into development practices
• Running Agile ceremonies including stand-ups, sprint planning and retrospectives
• Managing day-to-day delivery and proactively removing blockers
• Acting as a key technical contact for stakeholders and clients
• Supporting solution design and maintaining strong engineering standards

Experience Required
• Proven experience operating as a Tech Lead or Lead Engineer in modern engineering teams
• Strong Python development experience within full-stack environments
• Experience with TypeScript, React and Azure-based architectures
• Experience working on financial modelling systems, ideally involving forward-looking modelling such as discounted cashflow projections or Monte Carlo simulations
• Demonstrable experience implementing AI-assisted or agentic engineering approaches in practice
• Experience leading engineering teams within Agile delivery frameworks
• Strong communication skills and the ability to engage confidently with clients and stakeholders
• A solutions-oriented, detail-focused mindset with a strong delivery drive and principles-based approach to engineering
