Java Architect - Top 4 Global Leader of Payroll - £90k I’ve partnered with a top 4 global payroll leader that’s deep into a tech transformation. They’ve outgrown their legacy stack and are rebuilding from the ground up, creating a workflow-driven, scalable platform that’s genuinely intuitive for users and clients.We’re looking for a Java Architect with solid experience in guiding how systems evolve and ship. The role is primarily Java-focused, with architectural decisions around modernisation, performance, and scalability. The tech stack includes Java, Spring, Azure, CI/CD pipelines, and infrastructure-as-code practices. You will be working closely with the Developers in the team. You’ll be leading the design of APIs for high-volume global payments, driving UX improvements through workflow orchestration, embedding security from the foundation up, and shaping how the platform scales internationally.It’s mostly remote, with a salary up to £90k + pension, private medical cover, personal development plans, and a streamlined two-stage interview process.If you enjoy turning legacy code into clean, modern architecture — and want to see your decisions have a real product impact — this could be a great fit.Feel free to reach out if you’re curious, or know someone who’d be great for it.
