Senior/Staff System Test Engineer

Our vision is a new category of habit‑forming healthcare globally; one that is patient‑centred, predictive, and intrinsically scalable. We're a digital‑native healthcare provider, using personalised video streams to deliver treatment pathways at population scale, with transformative economics. By personalising each patient’s interaction in real‑time, we deliver world‑class medical treatment in an engaging consumer experience.

You’ll be Flok's first dedicated test hire, and will take ownership of testing and product quality, for both our patient facing application and internal clinician tools. This is an individual contributor role (at least for the foreseeable future), but with scope for technical leadership in terms of setting testing strategy and direction.

Your day-to-day work will be impactful and varied, including:

• Designing and building automated tests (particularly e2e, scale and device‑compatibility tests)
• Performing manual testing (where it adds value)
• Setting overall test strategy, prioritising test efforts, and writing clear QA plans
• Managing the software release process and documenting releases for medical device regulatory compliance
• Reviewing product requirements
• Participating in bug triage/diagnosis and incident investigations
• Configuring CI systems and maintaining test environments
• Improving system observability to facilitate easier testing and debugging
• Providing input into system design decisions with a focus on testability
• Fixing some of the bugs you find (where appropriate)

You’ll collaborate closely with the rest of the engineering team (who will continue to also write tests) and all Flok employees (who will continue to help QA the product internally), but you’ll be the go‑to expert dedicated to test strategy and quality ownership. You’ll also help mature our engineering processes as we grow, mentor new team members, work directly with company leadership, and see the impact of your work on real patients.

You have strong programming skills (ideally in Python / TypeScript). You bring wide‑ranging system/software test experience, including a breadth of different styles of testing, and with a focus on whole system testing and overall product quality. You’re comfortable setting up CI systems and test environments. You enjoy working with design and product teams to help shape exceptional products. You care deeply about your users - championing great experience and access to quality clinical care. You take initiative and ownership of your work, and communicate clearly.

Whilst not required, experience in any of these areas will definitely stand out:

• Software medical device development (or another regulated industry)
• Working with video streaming and/or real‑time technologies
• Startup experience
• Managing software release processes
• Setting test strategy for your team/product/company

Interesting and challenging work, in‑person working from a beautiful workspace in the Cambridgeshire countryside, an onsite gym, a digital health subscription of your choice, early stage equity with employee‑friendly terms (via an EMI scheme), comprehensive medical coverage (including dental and optical) and life insurance, optional remote working on Wednesdays, with an annual allowance of 10 extra remote days, desk setup allowance for your favourite keyboard/mouse/whatever! Regular pulse‑checks to help us build a culture we’re proud of, monthly team BBQs and desserts on Flok, a fast-paced work environment geared towards excellence and professional growth (with annual training budget), top notch specialty tea and coffee, and a chance to have a big impact in a small early stage team making a difference to the lives of people across the UK.

More than a billion people a year suffer unnecessarily from conditions like back pain, where the right treatment approach is well-established but undeliverable at scale. We’re changing that. Our team has deep expertise across clinical, engineering and machine learning, has a track record of healthtech innovation, and is backed by top‑tier VCs and multiple unicorn founder angels.

Solving hard problems at the intersection of software & healthcare/data science, the pursuit of excellence—helping each other to do the best work of our careers, working in an in‑person collaborative environment, and taking ownership to have significant impact early-on in a growing company with big ambitions.
