Job description

Our client is a pre-seed, London-based startup building a universal financial intelligence layer for the healthcare industry. With $2M in funding from top-tier VCs, they're tackling a massive, untapped market: providing financial visibility to the dental industry, which currently lacks the tools to unify fragmented data across various systems. They've already found product-market fit and are poised for rapid growth. This is a unique opportunity to join a small, early-stage team and help build the foundation of a global platform.

Our client is looking for a Software Engineer to work directly with the CTO and own problems from end-to-end. This is a hands-on role for a product-minded engineer who is dedicated to building scalable and durable systems. You will be instrumental in developing the core product, which will include building payment workflows, integrations, and internal tools.

You will be responsible for:

• Building scalable systems to power PMS integrations and payment workflows.
• Taking full ownership of projects, from initial idea to deployed product.
• Collaborating cross-functionally with product and commercial teams.
• Driving engineering quality by following clean code principles and best practices.

We are seeking a product-minded engineer with a strong backend or full-stack background who has experience in a fast-paced, scaling startup environment. The ideal candidate is an entrepreneurial builder who cares about the "why" behind their work.

Must-Haves:

• 3–8 years of experience building production-grade systems.
• Proven experience with data-heavy applications and pipelines, especially in fintech or health tech.
• Proficiency in the core tech stack: TypeScript, Next.js, Node.js, and PostgreSQL.
• Experience with services, APIs, and infrastructure.
• Willingness to work in-person, 5 days a week, in London.

Bonus Points:

• Experience in payments or health tech.
• A background with side projects, or as a founder or founding engineer.
• A strong, entrepreneurial mindset.

• Salary: £75,000–£100,000 GBP per year
• Equity: Competitive
• Visa Sponsorship: Not available
