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.

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.

Role Overview

We are looking for a Staff Software Engineer excited to tackle some of the hardest technical problems in healthcare, building the software infrastructure of modern hospitals.

The role focuses on writing clean, robust code and re‑building from scratch the all‑encompassing platform.

  • Technical Challenges (Responsibilities)
  • Modern cloud architecture, built from scratch: design a modern cloud‑native platform with Elixir at its core.
  • Develop a radically better access control system for clinical data: create a modern system with fine‑grained permissions that respects clinical data structure and patient data ownership, while enabling population‑level insights for better public health.
  • Keep hospitals online 24/7: design and ship infrastructure that can handle rolling deployments, failover, and real‑time data sync in environments where downtime isn’t an inconvenience – it’s a risk to patient care.
  • Bridge the gap between software and hardware: architect a next‑generation integration engine to connect ventilators, bedside monitors, imaging equipment, lab equipment, and more – reliably and in real time.
  • Push hospital workflows into the modern age: rethink and rewire how data moves between nurses, doctors, and administrators – and turn confusing, click‑heavy workflows into fast, intuitive experiences.

Qualifications / 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 (Phoenix, Elixir, Python, Erlang, Java Script, 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.
  • Passion for making a meaningful impact in the healthcare industry through software innovation is a plus.

EEO Statement

All applicants will be considered for employment regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, veteran or disability status.
