We curate the world's best wellbeing brands across The Four Pillars™: EAT, MOVE, MIND, SLEEP.
We are moving from one market to many, from e-commerce to a technology platform, and from curating wellbeing to defining it.
We are a health company, so we think we should act like one.
We think the companies that win the next five years are the ones that put a capable AI agent behind every function in the business, faster and more reliably than anyone else.
AI engineering is the functional label.
When an agent is a short build, they use what is already there, Claude's managed agents or something off the shelf, and they ship it the same week.
When the problem is genuinely complex, they reach for Lang Chain, Lang Graph, Pydantic AI, and instrument it properly in Lang Smith.
You will be hands-on in the code, shipping, not directing from a distance.
Frameworks like Lang Chain, Lang Graph and Pydantic AI where the problem demands it, with evaluation and observability through tools like Lang Smith built in from the start.
Reusable building blocks.
You will drive velocity by building reusable building blocks.
You ship, watch how it behaves with real users, and tighten it.
You will own these calls with authority and the context to make them well, and you will not default to building when buying is faster and just as good.
The core one is evaluation: you decide what a good answer looks like before you ship, build a way to measure it, and keep measuring so quality never quietly slips when a model or a prompt changes.
On top of that, where a human stays in the loop, and how we trace what an agent did versus what it claimed.
You will research what is new in agentic AI, test what is worth testing, and bring the best of it into how the team builds.
Then you will level up the people around you, so Healf is always building with the best available approach, not last year's.
You will report to the Head of Data and AI and work hand in hand with the CTO. You will have real authority over how AI gets built across the company.
A growing library of live agents across multiple functions, each removing real hours of manual work every week
- A growing set of reusable building blocks, so each new agent ships faster than the last
- The early nucleus of an AI engineering team built around your judgment
Shipped, live, used.
You have used managed and off-the-shelf agents to ship something in a day, and you have built something far more involved with a framework when it was worth it.
You track what is new in agentic AI, form a fast view on what is real and what is hype, and fold the good parts into your work and the team's.
You are close to the business, but this is a building role first. You are looking for the thing worth building next.
It requires shipping autonomous systems into a live business, where a bad decision has real consequences, and doing it without the luxury of consensus.
If you want to spend the next two years building something foundational that the rest of the company will build on for a decade, this is that opportunity.
How did you measure quality, and how did you catch it slipping when something changed?
