Senior Python Developer £700/day inside IR35

Senior Python Developer - Finance

London | Hybrid - 3 days per week
£700/day Inside IR35 | 12-month contract
Permanent / FTC options also available

We're working on a number of new Senior Python Developer opportunities within a major Financial Services technology environment, supporting significant investment across trading, regulatory and enterprise engineering platforms.

These are long-term hires rather than short-term backfill, with multiple teams looking to bring in experienced Python Developers who are comfortable building business-critical applications in a complex banking environment.

You'll be working closely with engineering and business stakeholders to design, build and enhance Python applications supporting a mixture of markets, regulatory and front-office technology. Depending on the team, there may also be opportunities to work with AI-assisted development tooling, security-focused applications and new Proof of Concept initiatives.

The environment is fast-paced and engineering-led, so we're looking for people who can take ownership of their work, communicate well with stakeholders and contribute beyond simply picking up development tickets.

We're looking for:

Strong commercial Python development experience

At least a couple of years' experience working within finance environment

Experience building enterprise-scale applications

Financial Services / Banking experience

Comfortable working within Agile engineering teams

Strong communication and problem-solving skills

Experience across Trading, Front Office technology, Regulatory Technology, security-focused development or AI-assisted engineering tools such as GitHub Copilot would all be beneficial, but aren't essential.

You don't need to be an AI specialist. An interest in how AI is changing software engineering and modern development practices is more important.

The initial option is a 12-month contract at £700/day Inside IR35, working 3 days per week from a London office.

There is also flexibility for candidates who would prefer something longer term, with permanent opportunities up to £100,000 and 12-month FTC options up to £120,000 available.

If you're a strong Python Developer with solid banking experience and you're looking for a sizeable programme where there is genuine investment in technology, this is well worth a conversation.
