Senior IT Infrastructure Engineer

01Health is at an inflection point. The platform is built, revenue is accelerating, and we are moving from a single-specialty company to a multi-vertical specialist healthcare platform - with AI as embedded clinical infrastructure. Our vision is to help all clinicians deliver the latest innovations in healthcare, improving the standard of care for millions of people.  Backed by the investors behind Revolut, CityMapper, and Depop - we're scaling fast across the UK and beyond, and are looking for exceptional people to join us on our mission.  What is happening at 01Health right now: Balderton-backed Series A company 90% of UK patients can reach an 01Health–affiliated clinic within 30 minutes All growth has been inbound, ~50% word of mouth 4.98★ customer rating from the dentists who use us Aerox (sleep) ready for national rollout to top-performing 01Partners, with a 300+ clinic waitlist US expansion live New verticals being tested and prototyped We are not searching for product–market fit anymore. We are ready to dominate the market, and to do it across multiple medical specialties, transforming lives in the process. The role 01Health is scaling fast - and we need the infrastructure to match. As our first dedicated IT/Infra Engineer, you'll own the cloud infrastructure that powers our remote workforce, manage IT for our London office, and build the operational foundation that keeps 01Health running reliably as we scale. This isn't a ticket-closing role. We want someone who can firefight when needed but spends most of their time building the systems, processes, and automation that mean fires don't start in the first place. You'll sit within the engineering team, reporting to Nik (our tech lead), and work closely with Surendra (DevOps) and the wider tech and operations team. We are an AI-first company. We have a growing AI team building tooling across the business, and we expect this role to plug directly into that - identifying where repetitive IT and helpdesk work can be automated away and building or commissioning the tools to do it. There is real scope to reshape what an IT function looks like with AI at its core.

Comfortable with ambiguity and making sensible decisions without detailed specs Excited about AI as a practical tool - to automate workflows, build internal bots, or reduce toil Strong spoken and written English; communicates clearly with non-technical stakeholders Available for meaningful UK hours overlap - roughly 6am-3pm UK time   Why this role A rare opportunity to be the first IT/Infra hire at a fast-scaling health-tech company - you'll build the function from scratch with real autonomy Real infrastructure challenges from day one - cloud VM architecture, HIPAA compliance, scaling a production server-side application across a global team Opportunity to work closely with a strong engineering team and direct exposure to senior leadership 01Health is growing fast - your scope and impact grow with it AI-first from the ground up - a chance to reshape what an IT function looks like with AI at its core
