Senior Software Engineer - Real systems. Real trust. Real engineering.

• Senior .NET Developer
• Daily Rate Contract: €500-€600
• Hybrid Role | Dublin

Real systems. Real trust. Real engineering.

Build software for business-critical systems that cannot fail. Trading, risk, research and payments at a global investment firm all depend on it, and you would be the one rebuilding what is outdated, building what is missing and shaping what comes next.

This is a senior .NET role with no backlog to inherit and no single product to maintain. A growing technology function needs an experienced developer who will sit down with the people who use the software, understand what they need and decide how best to deliver it. Your judgement will shape what the business relies on tomorrow.

You will work hands-on with C# and .NET, backed by SQL and Python where relevant, to redevelop legacy platforms, modernize established codebases and build new systems. The work spans backend services, desktop/UI applications and system integrations across trading, risk, research, payments and investment operations.

Why You’ll Love It

• Your judgement counts: Make the architectural calls and take pride in watching your work run in production, knowing it is there because of your decisions.
• Build the right thing first time: With a direct line to the people who use the software, you skip the guesswork and deliver what the business actually needs.
• Work that gets noticed: Modernize a legacy platform and see the difference it makes to the people who rely on it every day.
• Domain expertise that sets you apart: Build hands-on knowledge of trading, risk and payments systems. It is a specialism that few developers can claim, and it makes every future contract easier to win.
• Variety that keeps you sharp: Move across business areas and stay engaged as each project brings a new domain, a new stakeholder and a new technical puzzle.
• Stability and flexibility in one package: Enjoy a six-month initial term with strong potential for extension, plus a hybrid model of three days on site in Dublin and two days working from home.

Engagement Terms

• Rate: €500-€600 per day
• Term: 6-month initial contract, with strong potential for extension
• Location: Dublin, hybrid (3 days onsite, 2 days remote)
• Environment: A growing technology function within a global investment management firm
