Senior TypeScript Back-End Engineer - £80,000-£100,000 + Bonus Hybrid - 3 days/week in London

My client helps private clinics reduce patient anxiety and affordability barriers by pairing educational treatment content with an embedded finance solution - so more people can access the care they need. Backed by a purpose-driven B-Corp, they combine the stability and industry expertise of an established leader with the agility of a startup. Having launched their initial product and gained traction, they're now scaling for phase two.

They're looking for a Senior Back-End Engineer who blends technical depth with product intuition - someone who'll shape the platform, lead from the front, and solve complex scaling challenges in healthcare fintech.

What you'll be doing:

This isn't just about shipping endpoints - it's about owning problems end-to-end and influencing the product lifecycle. You'll:

• Lead and collaborate with engineers to design, build, and support extensible, low-maintenance back-end services.
• Partner with Product, Design, Operations, and Growth to prioritise customer-facing and internal problems that drive value.
• Champion security, observability, and reliability best practices.
• Mentor teammates and help cultivate a healthy, innovative engineering culture.

Tech Stack:

• Core: TypeScript / JavaScript (server-side)
• Cloud & Infra: AWS (cloud-based architectures), Docker, CI/CD; IaC such as Terraform or CloudFormation
• Quality & Ops: Security and observability tooling/best practices
• Bonus exposure: React on the front end (nice to have)

What we're looking for

We value skill and impact over strict year counts. You should have:

• Strong TypeScript/JavaScript fundamentals and experience building high-traffic server-side web applications.
• Solid understanding of cloud-based application architecture (preferably AWS).
• Hands-on experience with Docker and CI/CD tooling.
• Practical grasp of security and observability best practices.
• Clear, collaborative communication and leadership skills.

Why join?

• Competitive package: £80k-£100k + Bonus, up to 10% employer pension, 28 days holiday (plus bank holidays), health cash plan, 4 life assurance, £600 health & wellbeing budget, away days, and flexible working.
