Founding Engineer
Untether Labs
About Untether Labs Untether Labs is a workforce management platform for large health systems and digital mental health clinics. Our AI‑powered scheduling tools ensure that doctors and nurses are scheduled in ways that empower them—optimizing the number of patients they see and their own personal satisfaction with their work. We’ve rolled out with a handful of large contracts already (totaling ~1000 providers scheduled using our tools), and we’re looking to expand our team in order to tackle our biggest contract and challenge yet—replacing an existing $22 billion dollar software company from scratch! About Our Team Our team is a group of five engineers, embodying a ‘small but mighty’ spirit. We are defined by our kindness, autonomy, bias for action, and supportive accountability. We're a team that's determined to win by supporting healthcare providers to give the best care possible. More about us here: What You’ll Do We have an ambitious goal for the next 6‑12 months (and beyond) – replace existing multi‑billion dollar WFM software to enable better healthcare outcomes and margins for hospitals. It’s an ambitious goal, and we’ll need ambitious teammates to build out dozens of enterprise‑grade features in the coming months. You’re a great fit for our team if you … You love to work directly with users (every engineer meets with our customers multiple times a week). You crave autonomy and ownership (we all build out entire feature‑lines independently, although we love chatting and working together when we can). You’re incredibly fast and tactical (there’s a lot to build so velocity is key—the best product teams ship fast and frequently). You know how to build software that will last (our new product lines quickly go from 0 users → 1000’s of users in months, so being prepared to scale is critical). You’ve done this before (we love former founders + early stage founding engineers! All great talent is welcome, of course). Who You Are Minimum Requirements 5+ years in engineering across a wide range of products. Can build features end‑to‑end across the entire stack, from design to prototype to launch. Incredible attention to detail, especially around the business requirements of our users. Thrive in a collaborative environment involving different functions, stakeholders, and subject matter experts. Work great with a collaborative team, and help grow our culture and skills over time. Preferred Qualifications Experience building applications using NextJs/Typescript (most of our stack uses this!). Experience with building ML/Forecasting models quickly (predicting patient demand for providers is a frequent ask). Deeply in tune with how to run and grow a business, and can cut through the noise to deliver outsized impact. Demonstrated experience in leading large initiatives across teams with many stakeholders (enterprise software is done best with tactical thinkers). Strong, demonstrated communication & writing abilities, both in terms of documentation intended for end‑users, and executive/strategic comms intended to manage stakeholder relations and large rollouts. Tools We Use Languages – TypeScript, Python (Data Science) Libraries – React Datastores – Postgres Infrastructure – Vercel, Supabase Design – Figma Version control – Github Internal Wiki – Notion #J-18808-Ljbffr
