Job Description


If you enjoy a job where C++ meets interesting maths and the occasional “why does this code even exist” moment, you’ll probably like this one.

This is a more junior-friendly role with a clear learning curve, proper support, and the chance to work on genuinely complex systems without being expected to know everything on day one.


About the organisation

This is a financial consultancy growing its asset management engineering team. It’s a small, collaborative group working on systems that support real investment decisions. You’ll be joining a team that already has experienced engineers in place, so there’s plenty of opportunity to learn and develop.


What you’ll do

  • Work on modernising a quant modelling platform used by portfolio and investment teams
  • Contribute to C++ code that powers financial models and analytics
  • Learn how large-scale modelling systems are designed and maintained
  • Support improvements to tooling, build systems, and overall code quality
  • Get exposure to AI tools and how they can be used in engineering workflows
  • Ask questions, break things (safely), and figure out how they work


What you need

  • Solid foundation in C++ (this could be from university, internships, or early career experience)
  • Strong maths skills and an interest in problem solving
  • Degree in Maths, Physics, Computer Science, or similar (Master’s is a plus, not a must)
  • Curiosity and willingness to learn, especially when things get complex
  • Ability to communicate your thinking, even when you’re not 100% sure yet


The practical bits

  • Salary: €40-55K depending on experience
  • Fully remote within Ireland
  • No visa sponsorship


Interview process

  • Intro call
  • Technical interview (focused on how you think, not just what you know)
  • Final chat with the founder
