Company Overview At Florence, we’re on a mission to make the healthcare industry simpler and fairer for everyone—in the UK and beyond. Since founding in 2017 we've grown across the UK, France and Canada. On top of our core staffing business linking healthcare professionals with healthcare organisations, we've recently switched gears to provide outstanding workforce technology for the healthcare sector, from rostering to agency management, payroll and HR, Florence is becoming the all-in-one platform for healthcare organisations to solve their workforce challenges. The Role We are seeking a Senior Product Engineer to join our Product Engineering team. This is a high-impact Individual Contributor (IC) role designed for an engineer who excels at execution and technical craft but is equally driven by product strategy and user value. You will join a cross-functional team (alongside a Product Manager, Product Designer, and other Engineers) to own features from the discovery stage through to deployment and monitoring. You are a builder who wants to ship code that solves real problems for care professionals and care homes. What You Will Do • Own Features End-to-End: You will write clean, maintainable Ruby and React code. You are comfortable jumping between the backend business logic and the frontend user interaction., • Partner with Product: You will be involved before the project is kicked off. You will work with the PM and Designer to assess feasibility, suggest technical trade-offs, and refine the solution., • Mentorship (Not Management): You will set a high standard for code quality. You will review PRs, pair with mid-level engineers, and mentor them technically, but you will not be responsible for HR, hiring, or performance reviews., • System Health: You will ensure the product is performant and bug-free, writing comprehensive tests and monitoring errors.

You know the "Rails Way," but you also know when to break the rules. You are comfortable with modern React patterns., • Product-Minded: You don't just execute tickets. You ask questions like: "How does this help a care professional get paid faster?" or "Is this the simplest way to solve the user's problem?", • Pragmatic: You hate over-engineering. You know that shipping value to users is more important than using the absolute latest trendy library., • Empathetic: You understand that our users are working in high-stress healthcare environments. Reliability and usability matter., • Thrive in ambiguity: You dive into the unknown and work to bring people, ideas and problems together to form a clear cohesive plan
