Senior Full Stack Software Engineer

Altro Health•New York, NY

4d•$170,000 - $200,000•Hybrid

About The Position

Altro powers the next generation of wellness businesses with clinical infrastructure built for growth. We're building a platform that enables wellness businesses to offer clinical services they currently can't provide on their own, including blood testing, prescriptions, and peptides, supervised by a clinical team. The team behind Altro has done this before: Harvard Business School MBAs and a second-time founder, alongside operators and executives who've taken startups through exits as founding-team members. We're backed by top venture capital firms. The tailwinds are massive: Peptides going mainstream, GLP-1s unlocking the category, the longevity movement in full swing, and AI unlocking what wasn't possible a year ago. We're still early. Which means every hire matters. Join at the ground floor, work directly with the founders, and be part of something rare: a company at the intersection of a massive market shift and the moment when AI is reshaping what small teams can build.

Requirements

4-7 years writing production software. Quality and ownership matter more than years.
Deep TypeScript + React/Next.js fluency. You've shipped complex, polished interfaces and think about component architecture, state management, performance, and accessibility.
Strong design sensibility. You can take a Figma file and ship something that feels exactly right — and push back when something could be better.
A modern typed backend language in production. You're not a front-end specialist; you can build the API your front-end consumes.
API design experience (GraphQL, REST), schemas, contracts, versioning.
Comfortable with a cloud platform (GCP, AWS, or Azure) and infrastructure configuration.
A track record of owning features end-to-end, not just pieces.
Clear writing and strong async communication — critical for a small team moving fast.
High agency. You spot what needs to be built, scope it, build it, ship it. You don't wait for a perfect spec.

Nice To Haves

GraphQL at real scale (schema design, performance, tooling)
Animation libraries (Framer Motion, GSAP) or advanced CSS/Tailwind work
Design system experience — building or maintaining one
Comfort with tracing, metrics, and structured logs

Responsibilities

Build the interfaces customers see and touch. Consumer, partner-facing, and clinician-facing portals — polished, fast, intuitive. UX matters here.
Own features end-to-end. From fuzzy problem ("operators want X") to shipped product (the page, the API, the migration, the analytics) — all of it.
Work full-stack, with most of your day in the front end and the rest in the backend services that power what you're building.
Partner closely with our designer to ship polished UI. You care about the difference between "it works" and "it feels great to use."
Leverage AI tooling throughout the SDLC — write, review, and deploy with AI where it helps. Speed matters. So does quality.
Work across a small cross-functional team — clinical ops, product, design, sales. No throwing things over the wall.
Engineer for simplicity. Bias toward minimal dependencies, boring technology where it matters, and architecture that scales without ceremony.
