Lead Python Engineer – AI & Data

We’re working with a leading consulting firm on a long‐term engagement with a major financial services client. They are looking for a Lead Python Engineer to set the engineering bar across several Python services while remaining highly hands‐on.

The opportunity

You will:

• Lead the design and development of Python‐based services and REST APIs (Django or similar) used across multiple AI and data use cases.
• Own and manage the code repository: structure, branching strategy, pull requests, code reviews and refactoring standards.
• Implement and enforce software development best practices – CI/CD, automated testing (unit and integration), static checks and quality gates.
• Drive a focus on code simplicity, performance and maintainability, continuously improving the codebase through regular refactoring.
• Work in a full‐stack environment: Python/Django on the backend, templates or light front‐end integration where needed, running in containers (Docker/Kubernetes) with DevOps support.
• Mentor and upskill other developers (including offshore team members), providing clear feedback and helping to embed consistent ways of working across pods.

What we’re looking for

Must have:

• Advanced Python experience building production systems and APIs (Django or comparable framework).
• Demonstrable experience owning a codebase: repository management, branching/PR workflows, code reviews and refactoring.
• Strong grasp of engineering best practice: CI/CD pipelines, automated testing, monitoring and documentation.
• Experience working in a containerised environment (Docker; Kubernetes strongly preferred).

Should have:

• Exposure to front‐end integration (Django templates or similar) and an understanding of how the full stack hangs together.
• Experience in financial services or consulting environments.
• Previous responsibility for mentoring or leading developers within a team.

Details

• Location: UK‐based, hybrid working with onshore and offshore teams.
• Contract: 3–12 months, with potential to extend.
• Day rate: £700 per day
