Senior Software Engineer – Backend AI Native

Simple Online Healthcare

Location: Glasgow, Hybrid

Salary: £65,

About Simple: Simple exists to make personalised healthcare easier to access, understand and act on. Our goal is to remove the friction people face when trying to get the treatments and support they need to feel their best. We’re building a modern, scalable platform from the ground up, powered by AI-native engineering that allows small, senior teams to deliver meaningful impact quickly.

• Join one of Simple’s first AI-Engineering teams a lean, senior, high-ownership engineering squad.
• Work in a spec-first, AI-native SDLC: AI generates code, tests, and documentation; you architect, review, integrate, and assure quality.
• Build core components of Simple’s healthcare platform.
• Own services end-to-end: design, implementation, observability, reliability, performance.
• Elevate engineering standards across pods, codify reusable patterns, and help define the golden paths for platform development.
• Help shape the engineering culture as one of the foundational hires, mentoring, pairing, cross-reviewing and sharing knowledge as we grow.

• Experience building production-grade software in modern languages (Type Script/Node.js (Preferred), Python, Java, Go - any strong engineering foundation is fine).
• Experience building cloud-native systems (AWS preferred):
  Lambdas, ECS/Fargate, API Gateways, serverless or containerised architectures.
• Strong skills in automated testing, CI/CD, and modern practices.
• Comfortable working with generative AI tools (or strong willingness to adopt them) to accelerate development.
• Deep understanding of software fundamentals: architecture, clean code, performance, observability, maintainability.
• Strong ownership mindset: you care about outcomes, not just code.
• Excellent collaborator: you work well in small, high-trust environments and you’re comfortable with pairing, knowledge sharing, and cross-pod communication.

• Experience in healthcare, digital services, patient journeys or regulated environments (not required).
• Full-stack experience:
  Comfortable working across the stack using React/Next.js when required, though core strengths are 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 engineering.

• Intro call - meet Talent & understand your motivations.
• Technical interview - architecture discussion, pairing, AI-workflow exercise.
• Final interview - culture, ownership, leadership behaviours.
