What makes this opportunity stand out?

  • Lead & grow a high-performing Dublin engineering team

  • Start with 5+ engineers, with significant growth planned

  • Remain hands-on with C# / .NET while developing your leadership scope

  • Influence architecture, technical strategy and the product roadmap

  • Work closely with senior stakeholders and have genuine ownership over technical decisions

What are we looking for?

  • 10+ years of experience working with C# / .NET

  • 5+ years of SQL experience

  • Strong experience with AWS or Azure

  • Proven experience in technical leadership / team leadership

  • Strong understanding of system design and scalable architecture

If you’re a .NET Team Lead, Principal Engineer or Engineering Manager who is ready for more ownership and wants the opportunity to grow a team while shaping the future of a major financial product, this could be a very interesting next move.
