Job Description:

Join a fast-growing health tech company using AI to solve high-impact, real-world problems. Building tools that help frontline professionals reduce admin and focus on delivering care, my client are looking for engineers who want their code to make a measurable difference.

What You’ll Be Building

• AI-powered web applications (think speech-to-text, smart summarisation, and automation of manual workflows)
• Scalable backend services and internal APIs to support data-heavy processes
• Realtime interfaces using modern frontend frameworks (HTMX/Turbo/Alpine or similar)
• Integrations with LLMs (e.g., OpenAI, Claude) to optimise and automate user workflows
• Developer tooling and infrastructure to support continuous deployment and high availability

Tech Stack Overview (this isn’t a list of all the things you need, just giving you a good overview of what is on offer)

• Backend: Ruby on Rails, PostgreSQL, Sidekiq, Redis, AWS
• Infra: Docker, Terraform, GitHub Actions, CloudWatch

What You’ll Do

• Write clean, well-tested code across the stack with a product-focused mindset
• Own feature development end to end — from design discussions to deployment
• Work with cross-functional teams to translate user pain points into elegant solutions
• Optimise application performance and system scalability as usage grows
• Drive architectural improvements and evaluate new tools/libraries

What We Look For

• 5+ years in software engineering, ideally across full stack environments
• Experience working on complex systems with meaningful scale
• A bias toward action and pragmatism: you ship working software quickly
• Strong product intuition and comfort collaborating beyond just engineering
• Interest in AI/ML — no PhD required, but hands-on curiosity essential
• Based in (or regularly able to visit) London for in-person collaboration
