Lunar is a stealth technology company building a new type of software platform for health systems. We are on a mission to
revolutionize healthcare with cutting-edge, AI-powered software designed to help every hospital deliver world-class care for their
patients. Our platform is already the core backbone of health systems today, transforming clinical and operational workflows at
scale with the world’s first AI-native hospital information system.
This next-generation platform is a fundamental rebuild of the information infrastructure that runs health systems. All of it –
from doctors, nurses, pharmacists, lab technicians, coders, billers, supply chain, and even patients – Lunar’s software powers
everything, soup-to-nuts. We believe that this mission is the moon landing of healthcare – something so consequential and
ambitious that most people believe it to be impossible.
Backed by Silicon Valley’s preeminent venture capital firms, we believe in the power of a high performance team of seasoned
professionals operating at the peak of their abilities. We value people who are driven, curious, have sound judgement, and care
about doing the best work of their careers.
We run hospitals on Elixir. We’ve embraced Elixir for its fault tolerance, concurrency, and scalability - essential for handling
real-time patient data in mission-critical settings like Emergency Departments, ICUs, and Operating Rooms.
We are looking for a Senior Product Engineer who’s excited to tackle some of the hardest technical problems in healthcare - and do
it with a fast-moving, and deeply mission-driven team. If you care about writing clean, robust code and want to rebuild from
scratch the software infrastructure of modern hospitals, we’d love to talk.
Here are some deep technical problems you may tackle in your first 6 months:
platform with Elixir at its core.
permissions that respects clinical data structure and patient data ownership, while enabling population-level insights for
better public health.
real-time data sync in environments where downtime isn’t an inconvenience - it’s a risk to patient care.
monitors, imaging equipment, lab equipment, and more - reliably and in real time.
and turn confusing, click-heavy workflows into fast, intuitive experiences.
technologies. We use tools such as Phoenix, Elixir, Python, Erlang, Javascript, and more.
applying strong fundamentals and first principles thinking.
Hospitals are some of the most complex, under-served environments in all of tech. We’re bringing the best of modern software
practices to an industry that’s been left behind - and building tools that clinicians love, not tolerate.
If you’re an engineer who wants to work on meaningful problems with real-world impact, this is your chance.
At Lunar, we know our greatest strength is the diverse blend of backgrounds, experiences, and ideas that our team members
contribute. We’re passionate about healthcare, but we are also passionate about creating an inclusive workplace where every unique
talent and perspective is not just respected, but celebrated. We thrive on embracing differences and are fully committed to
fostering a fair, supportive, and dynamic environment where everyone has the opportunity to shine. All applicants will be
considered for employment regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, veteran
or disability status.
