Quantitative Developer

If you enjoy a job where C++ meets heavy maths and the occasional existential crisis caused by a legacy codebase, you’ll be right at home here. This role is with a specialist consultancy and sits in a major UK financial institution’s asset management engineering group, where they’re rebuilding and modernising the modelling platform used by quants and portfolio teams.

This is a financial consultancy expanding its asset management engineering capability. The team is small, tight-knit, and focused on deep technical work that underpins large-scale investment decisions. They’re growing steadily, with several engineers already in place and more joining as the platform is rebuilt.

• Modernise and upgrade a bespoke quant modelling codebase used across asset management.
• Work on complex calculation engines that drive modelling, portfolio analysis, and financial decision logic.
• Integrate AI tools into everyday engineering workflows to boost velocity and clarity.
• Improve build systems, support modelling DSL development, and reverse-engineer existing behaviours to make everything more scalable.

• Strong C++ experience applied in finance, quant environments, or other highly mathematical domains.
• Advanced academic background: a Master’s degree with 3+ years’ experience or a PhD in Maths, Physics, Astrophysics, Computer Science, or a similar discipline.
• Excellent mathematical ability and confidence working with complex modelling or simulation logic.
• Clear communication skills and the curiosity to ask the right questions when something in the code starts acting like it has a mind of its own.

If you prefer untangling bespoke systems to making small talk, you’ll find this role refreshingly… well, calculable.

Salary ranges from £60K to £110K, depending on seniority and depth of experience.

The role is fully remote within Ireland or the UK.
