Senior Software Engineer (AI Native)

Award winning and growing fast. We've had a big year. Simple Online Healthcare was featured in the Financial Times 1000 Fastest-Growing Companies in Europe 2026, the Sunday Times 100 (the UK's fastest-growing companies) for 2026, and the inaugural Sunday Times Scotland Fast 50 for 2026. We also won the Fast Growth Business award at the inaugural Scottish Business of the Year awards. None of that happens without the right people, which is where you come in.

Every patient journey we fix starts with a service someone has to design, build and keep running. You'll take that work from first spec to production, owning the architecture, the observability and the reliability as you go. The standards you set now will be the ones every future engineer inherits, and few senior roles give you that much say over how a healthcare platform is built from the ground up.

What you'll be doing:

• Join a lean, senior engineering squad and own services end to end, from design through to production.
• Work spec first. AI generates the code, tests and documentation, and you architect, review, integrate and assure the quality of what ships.
• Build the core components of Simple's healthcare platform, with the observability, reliability and performance to back them up.
• Codify reusable patterns and help define the golden paths that every pod will follow.
• Shape our engineering culture through mentoring, pairing, reviewing each other's work and sharing what you learn as the team grows.

What we're looking for:

• Essential: Experience building production software in a modern language such as TypeScript and Node.js (preferred), Python or Java. A strong engineering foundation in any of these is enough.
• Experience building cloud native systems, ideally on AWS, using Lambda, ECS/Fargate, API Gateway, or serverless and containerised architectures.
• Strong skills in automated testing, CI/CD and modern delivery practices.
• Confidence using generative AI tools to accelerate development, or a clear willingness to adopt them.
• A deep understanding of software fundamentals, including architecture, clean code, performance, observability and maintainability.
• A strong ownership mindset. You care about outcomes, not just code.
• An excellent collaborator who thrives in small, high trust teams and is comfortable pairing, sharing knowledge and communicating across pods.

Desirable:

• Experience in healthcare, digital services, patient journeys or regulated environments.
• Full stack experience, including React or Next.js when required.
• Your core strength is backend, cloud native systems and platform architecture.
• Experience building scalable platforms, reusable components or high leverage engineering systems.
• Curiosity about AI native development and excitement about being part of an early shift in how engineering gets done.

Interview process: Intro call, then skills and technical interview, then final interview.
