But today’s clinical trial infrastructure is stuck in the past, and the cost of developing new medicines has skyrocketed as a result. Patients have to wait longer and pay more for new treatments. Our mission is to fix this; we use software to help innovative companies run faster, more reliable, and patient-friendly clinical trials. We’re still a young company, but we’ve already had a big impact. Since founding the company in March 2021 we’ve helped run over 100 clinical trials involving tens of thousands of patients, with a customer NPS of 100.

About the role Lindus Health is looking for a Staff Software Engineer to build the platform powering the next generation of clinical trials. We want to add a very experienced engineer to our small product team to do hands-on product development, drive long-term architecture and evolve our engineering practices as we grow into a mature organisation.

After an initial onboarding period full-time at our headquarters (near London Bridge) we expect you to be in the office at least 3 days a week. About you We’d like to hear from you if… You have at least 6 years of experience as a software engineer. This includes at least 1 year in a role that could be characterised as “senior+” - a role where you acted as a tech lead for a project with multiple engineers or where you demonstrated impact across multiple teams or functions. You are comfortable working across a stack that includes frontend (TypeScript/React), backend (Python/Django/Postgres) and infrastructure (AWS). You don’t necessarily have hands-on experience with all pieces of our stack but want to go deep in at least one area and are happy to pick up technology that’s new to you. You are product-minded: you want to understand why we are building something to figure out the best how in collaboration with product managers, trial managers and users. You are an excellent listener and communicator who can build consensus, drive decisions and resolve conflicts. You write clearly and know when to deploy written artefacts to move teams and projects along. You like a startup environment where you have lots of autonomy and opportunities to grow your skills. You want to have a major impact on architecture and engineering practices as we grow from a small team (2 PMs, 2 designers, 7 engineers) to a large organisation (we are hiring for 3 additional engineers right now!). You have high agency and a bias for action You are passionate and curious about our mission; changing how the healthcare industry operates and how new health treatments are developed You want to learn what life is like at a high-growth, mission-driven VC funded startup You belong here!

Collaborate Transparently We openly share our work and always encourage others to ask questions, even when it creates a certain amount of overhead and may invite too many perspectives. Take Ownership End-to-End We trust engineers to own the delivery of features from idea to production, even when it means taking time away from coding to collaborate with users, product management and design. Assume Collective Responsibility We treat every issue as a shared concern, even though you may have to fix things that you had no part in building or you have to accept changes to your work by others. Have Fun! We inject fun and silliness into our day-to-day work, even though it may take some time out of our day to craft the perfect meme or play darts to settle a dispute. What we offer (UK) Make an impact across all areas of our business and fix one of the world’s most broken industries Competitive salary, plus meaningful stock options Flexible working; we have an incredible office near London Bridge and encourage people to work 3 days per week from the office.
