I am working with a leading financial services firm who is seeking a Senior Haskell Developer to join a specialist team developing cross-product transactional pricing systems for derivatives.

This is a rare opportunity to work with a production-grade Haskell codebase, delivering high-performance Back End systems that support Real Time pricing and trading.

Key Responsibilities:

  • Design, develop, and maintain Back End services for derivatives pricing using Haskell
  • Lead the implementation of new features and performance enhancements
  • Collaborate with business analysts and global stakeholders to deliver value-driven solutions
  • Contribute to system architecture and technical direction of the platform
  • Engage in code reviews, pair programming, and continuous improvement initiatives
  • Support production systems and deployment pipelines alongside DevOps teams
  • Mentor junior developers and promote best practices in functional programming
  • Apply financial domain knowledge in derivatives pricing and risk management

Key Skills:

  • Proficient in functional programming (Haskell is preferred, OCaml/Scala also considered)
  • Experience building scalable, high-performance Back End/Server Side applications
  • Strong understanding of architecture and system design principles
  • Comfortable working in Linux environments and agile development settings
  • Financial markets experience (particularly derivatives) is advantageous
  • MSc or PhD in Computer Science, Mathematics, Physics, or another STEM field is preferred, but not essential with relevant experience

This is a full time role, with flexibility for hybrid working in their London office, 1 or 2 days per week. The salary on offer is up to £115k and a total comp of up to £160k.
