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 01 Partners, 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: We're hiring for one of the most critical and exciting roles at 01Health. As Head of Operations, you will report directly to the COO and own day-to-day operations, leading a team of 50+ people across clinical, support, treatment planning, supply chain, fulfilment, and specialist teams. You’ll play a crucial part in enabling our geographical (US) and product (Sleep) expansion. How we deliver the next 10x growth has AI at its core. Working with our COO and leadership team, your job is to take those plans and translate them into crisp, well-run execution on the ground - and to be the feedback loop back up: surfacing problems early, spotting where reality is diverging from the plan, and channelling ideas and intel from team leads back into leadership decisions. Operations is already performing strongly. We’re not hiring someone just to keep the lights on; we’re also looking for someone to play a key part in redesigning and scaling how operations works. What you'll do: Own and run day-to-day operations across our Orthodontic and Sleep products (UK and US), with full accountability for our high quality bar, performance, and output against agreed targets. Execute against the operations roadmap set by leadership. Break it down into clear workstreams, sequence the work, drive it through to completion, and report progress crisply. Manage and develop team leads across functions. Set clear expectations, hold a high bar on performance, and run a tight operating cadence (1:1s, weekly reviews, monthly business reviews). Hit SLAs and performance targets consistently. Track the numbers, understand why they are what they are, and act fast when they slip. Identify and unblock bottlenecks. Spot where work is getting stuck, get to the root cause, and fix it - whether that's a process change, a tooling tweak, or a difficult conversation. Treat operations as a product. Design, build, and continuously improve internal tools, workflows and systems. Drive adoption and impact of AI and automation across your teams. The COO and leadership team sets the AI build agenda; you make sure the tools land, get used, and translate into measurable change in how operations actually runs. Run capacity planning, forecasting, and resourcing across your three areas, partnering with leadership on hiring and headcount. Lead operational readiness for new markets and products, executing the rollout plan and surfacing what needs to change as you go. Manage day-to-day supplier and partner relationships across our manufacturers and product lines, with clear ownership of lead times, quality, and fulfilment reliability. What success looks like: Operations runs smoothly day-to-day without needing COO involvement in execution. SLAs and performance targets are consistently met across the three areas as volume scales. AI and automation tools the team is building are actually adopted, used well, and driving measurable improvement in throughput and quality. Team leads have a clear, supportive manager who holds them to a high standard - and they're getting better at their jobs because of it. Leadership has full, accurate visibility into what's happening on the ground: nothing is festering quietly, surprises are rare, problems are caught early. Roadmap items land on time, in scope, and with the team leads bought in. You're seen as the trusted operator the COO can hand a problem or a plan to and trust will get done well. You'll thrive in this role if… You have 5-8 years of experience, for example combining top-tier consulting or finance experience with at least one operations role in a high-growth environment. You are obsessive about execution and detail. You take pride in things being done well, on time, and to a high standard - not just done. You are hard-working and high-output. You don't need to be told twice, you don't drop balls, and you bring real energy and pace to the work. You're a natural project manager. You can take a messy goal, break it into a clear plan, run it, and report on it crisply. You're great with people. You can manage and develop team leads, hold a firm line on standards, and have hard conversations when needed. You're an excellent communicator - clear, concise, structured - and just as comfortable writing a sharp update to the leadership team as you are sitting next to a team lead unpicking a workflow. You operate well with ambiguity but you bring structure to it: you turn vague briefs into clear plans rather than waiting for clarity. You are AI-fluent and genuinely excited to drive AI adoption across your teams. You don't need to be the one building the tools, but you need to be a power user, a strong advocate, and the person who makes sure they actually land in the real workflow. You are commercially minded. You understand why operational metrics matter to the broader business and you make trade-offs accordingly. Why this role: You'll be the senior operations executor at a fast-scaling company, reporting directly to the COO with a clear seat at the table. You'll own day-to-day operations across three exciting frontiers from day one: our core business, our growing US operation, and our new Sleep product line. Few mid-level ops roles offer that kind of breadth and frontier exposure. You'll have a clear scope and a clear mandate: take strategy from leadership and turn it into excellent execution. No fuzzy lines. You'll work side-by-side with leadership and have real exposure to how a high-growth company is run from the top. AI is reshaping operations and you'll be on the front foot, driving adoption of tools and ways of working that will define how operations is run for the next decade. Clear path to grow as the company grows - whether that's deepening into Director-level ownership, scaling into new markets, or moving sideways into other parts of the business. Compensation is benchmarked to senior mid-level operator roles in the London market, with meaningful equity.
