NodeJS Jobs - June 2025

SonarMD is a healthcare startup using data to help people with chronic GI conditions maintain a better quality of life. We work directly with care teams to identify early signs of deterioration—so we can intervene before painful flare-ups or ER visits happen.

We’re hiring a senior data/backend engineer to help me (staff engineer) build our data platform from the ground up.

You’ll be the first dedicated data engineer on a small, mission-driven team. There’s no legacy stack—you’ll help architect and implement the systems that turn messy healthcare data (claims, EHR, wearables, patient surveys) into something actionable. The work you do will drive everything from reporting to predictive insights, and shape the foundation for future AI/ML capabilities.

We’re looking for someone who:

If you want to build meaningful systems that improve lives—and you like working with autonomy alongside another senior engineer—email me: avespoli@sonarmd.com Send a resume, GitHub, portfolio, blog—whatever shows how you think and what you’ve built. No cover letter needed. Full JD: https://sonarmd.com/join-our-team/

Company: Audio-First Test Prep Platform

Duration: ~10–12 weeks for MVP

Compensation: Paid contract – competitive rate (no equity)

Experience Level: Mid to Senior preferred (3 years +)

Funding: Final stages of mobilizing resources to begin the MVP build. The project timeline reflects this progression.

We’re building an adaptive, audio-driven test prep platform designed for nurses, pre-med students, law students, and other high-intensity learners balancing work, family, and study. Think voice-based Duolingo meets real-time spaced repetition.

We’ve already built the front-end and now need a self-directed, back-end/full-stack engineer to help us finish the MVP by late summer, early fall.

Ideal Stack (flexible):

* Node.js / Python / Firebase / Postgres / Supabase

* Open to suggestions if justified and lightweight

You might be a fit if:

* You’ve built and launched real tools or platforms before (not just internal dashboards)

* You like fast execution but also appreciate mission-driven projects

* You value clarity, minimal meetings, and aligned momentum

* You have the capacity for solo execution but are open to scaling

* We’re not offering equity or co-founder status. This is paid contract work with possibility for long-term relationship once MVP proves value.
