Job description

Job title: AI Engineer

Job type: Permanent

Salary: £120K – £150K + Equity

Role Location: London, United Kingdom

The Company:

We’re partnering with a well‑funded, fast‑scaling healthtech startup reinventing musculoskeletal care using proprietary AI and 3D‑printing technology.

The business has developed a web‑based, sensor‑free AI vision platform that transforms a 30‑second scan into a clinically approved, precision‑manufactured medical device. Already trusted by Fortune 50 employers, major health systems, and national manufacturers, the platform is expanding access to preventative care for hundreds of thousands of Americans.

Fresh off a stealth funding round led by top‑tier VCs, the company is:

• Growing 10x year‑over‑year
• Profitable month over month
• Scaling rapidly toward $100M ARR
• Operating with a high‑ownership, execution‑first culture out of Boston

This is a rare opportunity to join at a true inflection point – early enough to shape the company, late enough to have real traction.

Role and Responsibilities:

We’re hiring AI engineers to help build and scale the core systems behind an AI‑driven healthcare platform. You’ll have real ownership from day one, with a clear path to leading engineering as the company grows.

You’ll influence architecture, technical direction, and engineering culture – while working on technology that measurably improves patient outcomes.

Job Requirements:

• Strong experience with TypeScript and AWS, including infrastructure and architectural decision‑making
• Proven experience building and scaling backend systems for real‑time or AI‑enabled applications
• Deep understanding of API design and developer‑facing platforms
• Experience optimizing data pipelines and system performance at scale
• Strong fundamentals in security, reliability, and fault‑tolerant system design
• Product‑focused: You think deeply about user impact
• Ownership‑driven: You want responsibility, not hand‑holding
• Clear communicator: You can challenge ideas and collaborate effectively
• Bias to action: You move fast and ship often
• Mission‑motivated: You want your work to change lives, not just metrics
• Build technology that helps people move without pain
• Join early enough to shape architecture, culture, and leadership
• Operate in a no‑bureaucracy, high‑trust environment
• Receive meaningful equity in a rapidly scaling, VC‑backed healthtech company
