Backend Python Engineer, AI & Data
London / Remote (South East based, occasional travel to London)
£45,000 - £55,000 DOE
We are working with an exciting AI-first engineering firm in the enterprise retail and e-commerce space who are building some really interesting products across generative AI, data pipelines, and marketing technology for household-name clients.
Founded by two former leaders of a major digital agency with close ties to Google, they sit at the intersection of conversion-focused web development, AI-powered marketing, and data-driven strategy. Recent projects include building generative AI agents for national brands and predictive modelling for major high-street retailers. Everything is greenfield, meaning you will be building brand-new products from the ground up with real input into the architecture and approach.
They are now looking for a Middleweight Python Engineer to join their growing engineering team. You will design, build, and maintain API integrations, data pipelines, and internal tooling that connect marketing platforms, analytics services, and client systems.
So, who would suit this role?
A sharp, adaptable backend developer with commercial Python, Node.js or similar experience who wants to work on varied, technically interesting projects for well-known brands. You will be confident working across the full lifecycle of an integration: reading API docs, scoping the work, writing clean tested code, and deploying to production.
Key requirements:
- Professional Python or Node.js development experience
- Strong experience consuming and integrating third-party APIs (REST, OAuth 2.0, webhooks)
- Proven experience authoring APIs using frameworks such as FastAPI, Flask, or Django REST Framework
- Comfortable with relational databases (PostgreSQL preferred) and writing efficient SQL
- Experience with Git and collaborative development workflows
- Self-motivated and comfortable working autonomously in a remote-first environment
What they offer:
- Remote-first with occasional London travel for team collaboration and client visits
- 25 days annual leave plus bank holidays
- 5% employer pension contribution
- A collaborative, low-ego team that values quality engineering and continuous learning
- Autonomy and ownership over your work
- Exposure to a wide variety of technologies, platforms, and client challenges
This is a great opportunity for a mid-level Python developer who wants to work at the cutting edge of AI-powered marketing and web development, building products that have real commercial impact for brands everyone knows.
