Python Developer – Greenfield Risk Management build out

Python Developer - Market Risk Technology

London | VP Level | £150,000 base + bonus | Hybrid

We are working with a leading global investment bank that is continuing to invest heavily in the build out of a new generation Risk Management platform.

The programme is replacing and modernising legacy risk infrastructure with a scalable platform designed to support Risk Managers across multiple asset classes. Equities have already been onboarded, with further areas including FX, Fixed Income and Mortgages still to be built out.

They are now looking for an experienced Python Developer with strong Market Risk knowledge to join the team and play a hands on role in the continued development of the platform.

The Role

You will work closely with Risk Managers and technology teams to design, build and enhance scalable risk applications, taking ownership of technically challenging problems across risk generation, calculation and analysis.

The work includes

• Building high performance risk applications primarily in Python
• Developing functionality as new asset classes are onboarded to the platform
• Working with large position, reference and market data sets held within Snowflake
• Improving the performance of distributed risk calculations
• Investigating pricing and risk discrepancies between the new and legacy platforms
• Working directly with Risk Managers to understand requirements and translate them into technical solutions
• Supporting risk measures including VaR, Greeks, sensitivities and P&L
• Helping shape a strategic platform that will ultimately support risk management across the firm

What We Are Looking For

The strongest candidates will combine excellent software engineering skills with genuine experience building technology within a Risk environment.

You should have

• Strong commercial Python development experience
• Experience developing Market Risk or closely related risk technology
• Good understanding of VaR, Greeks and sensitivities
• Strong database and SQL knowledge
• Experience with Snowflake highly desirable
• Experience building scalable or distributed applications
• Understanding of financial products and their associated risk
• Experience working directly with Risk Managers, Quants or Front Office stakeholders
• AWS experience beneficial
• C#/.NET experience would be advantageous but is not essential

Experience across Equities, Fixed Income, Credit, FX or Commodities can all be relevant.

Why This Role?

This is not a maintenance position on an established risk system.

You will be joining a major greenfield build while significant parts of the platform are still being designed and developed. With Equities already onboarded and multiple asset classes still to come, there is substantial engineering work ahead and genuine opportunity to influence how the platform evolves.

It is particularly well suited to a strong Python engineer who understands the business context behind Market Risk and wants to remain hands on while working on a strategically important platform.
