Software Engineer – Legacy Modernization Project

Sector: Public Sector/ Financial

Fully Remote

Contract Length: 6 months (strong potential to extend to 12–24 months)

Rate - £400-450/ day (Outside IR35) (some flexibility for the right person)

We're hiring on behalf of a major software provider to the UK public sector, for a software engineer to work on a modernisation project related to a financial platform.

The Role

This is a hands-on position at the intersection of legacy stewardship and modernization. You'll take ownership of a core collections platform built in Objective-J/Cappuccino, alongside a wider stack spanning class="bg-amber-100">golang (APIs and reporting), a class="bg-amber-100">React front end, and an class="bg-amber-100">iOS component.. The organisation is moving aggressively toward a class="bg-amber-100">web-based class="bg-amber-100">SaaS model, with class="bg-amber-100">mobile retained specifically for field workers - so comfort operating across desktop, class="bg-amber-100">web, and class="bg-amber-100">mobile is essential.

Why This Role Exists

This part of the business has been running on legacy platforms that now need to be modernised. The result is a platform that's now reaching the limits of maintainability - and a real opportunity for someone to join the team to shape its transformation. You'll step into an environment with an existing embedded team already in motion. The long-term direction involves an expected move to class="bg-amber-100">Go-based class="bg-amber-100">microservices, aligning with the class="bg-amber-100">rest of the organisation's engineering strategy.

What We're Looking For

• Strong Objective-C/J background with experience on Cappuccino frameworks, ideally with polyglot experience - some class="bg-amber-100">Go or class="bg-amber-100">.NET exposure is a bonus, but not a dealbreaker for the right specialist
• Experience with building class="bg-amber-100">web based products in class="bg-amber-100">React/ JS.
• Comfortable owning a technically diverse estate: legacy desktop, modern class="bg-amber-100">web, and class="bg-amber-100">mobile
• An engineer who can operate in a fast-moving, change-friendly environment and bring genuine energy to modernization work rather than just maintaining the status quo
