Staff Software Engineer

About Us:

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 small, 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 real-time patient data processing in critical settings like Emergency Departments, ICUs, and Operating Rooms. We are looking for a Staff Software Engineer to take on complex engineering challenges as we build and scale Lunar’s platform. Join us to design and implement high-impact solutions that improve hospital operations, enhance clinical workflows, and push the boundaries of healthcare technology.

Over the next 6 months, here are some deep technical problems you may tackle:

• Team Impact: Thrive in a smaller team environment where you can ideate, implement, and champion best practices.

• Modern Cloud Architecture: We are building everything from the ground up in Elixir, with no legacy baggage

• Data Access Control: Building a modern access control system that respects clinical data structure and patient data ownership, while enabling population-level insights for better public health.

• High-Reliability Engineering: Zero-downtime deployments in 24/7 mission-critical environments

• Hardware Integration Engine: Architect a next-generation integration engine to interface all the hardware infrastructure at each hospital

• Be part of a Mission Driven Company: We are applying cutting edge technology to the healthcare sector, revolutionizing an industry that has been left behind by software advancements over the past decade.

Your Experience: 

• Minimum of 10 years of professional software engineering experience.

• Proficiency with object oriented and functional programming, with the ability and willingness to use and adopt new technologies. We use tools such as Phoenix, Elixir, Python, Erlang, Javascript, Node.js and more.

• Strong ability to work in a fast-paced, collaborative, and innovative team environment.

• Exceptional problem-solving skills, with a track record of tackling challenging engineering problems. 

• Intellectually curious with a growth mindset - able to tackle entirely novel challenges that lack prior precedent through applying strong fundamentals and first principles thinking.

• Familiarity with open-source technology and a desire to explore and experiment with new solutions.

• Experience building 0-1 with a strong product sense.

• Excellent communication skills and the ability to articulate technical decisions, trade-offs, and best practices.

• A passion for making a meaningful impact in the healthcare industry through software innovation is a plus.

Lunar supports a flexible hybrid work environment. We encourage in-person collaboration with an expectation of working onsite three days a week. Our approach is designed to offer the flexibility of remote work while fostering the creativity and connection that come from face-to-face time with the team.

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.
