Lead Software Engineer – Python, React & AI

Lead Software Engineer – Python, React & AI Bristol | Flexible Hybrid Working | £80,000–£110,000 + Bonus + Benefits | Permanent Intelligent Talent is recruiting experienced Lead Software Engineers (Tech Leads / Technical Lead) for an international professional services organisation expanding its software engineering capability and developing new AI-powered applications.

The focus is on building production software using Python, React, TypeScript and Large Language Models, with increasing investment in agentic AI. This is a hands-on engineering position. Around 70–80% of your time will be spent building software, with the remainder focused on technical leadership, architecture, mentoring and working with product teams.

If you're a senior engineer who enjoys writing code, solving difficult technical problems and helping other developers improve, this role offers the chance to take ownership of new product development without moving into a predominantly management-focused position.

What you'll be doing You'll join the internal software engineering function, working on new applications designed to improve how complex legal and document-intensive services are delivered. The organisation is investing in its own engineering capability, with new Tech Leads taking responsibility for technical delivery and supporting the growth of the teams.

The role involves: Leading a scrum team through the design, development and delivery of new software products. Remaining hands-on with Python, TypeScript and React, taking features through to production. Building applications that integrate LLMs, Generative AI and agentic capabilities.

Taking ownership of technical design decisions and contributing to wider architecture discussions. Working with product owners, users and architects to turn requirements into practical software solutions. Mentoring engineers and improving code quality, testing and development standards.

Taking responsibility for applications beyond deployment, including reliability, maintenance and support. Making effective use of AI coding tools such as Claude Code and OpenAI Codex to improve development efficiency. You'll work closely with an internal DevOps and platform engineering team, so while cloud and infrastructure knowledge is important, the emphasis is on software engineering and product delivery.

Technical environment The team works primarily with: Python for backend engineering React, TypeScript and JavaScript for application development Microsoft Azure for cloud infrastructure and services PostgreSQL and Cosmos DB for data storage
