Senior Full Stack Engineer – Build the Future of Healthcare Automation

Location: Remote (US Time Zones) Outside US - Hybrid (If based in US) Type: Full-time Seniority: Senior Compensation: Competitive salary + meaningful equity About Solum Health At Solum Health, we’re on a mission to rebuild the broken back office of healthcare—one voice agent, workflow automation, and AI model at a time. Today, outpatient specialty clinics in the U.S. are buried in administrative chaos—referrals sent by fax, handwritten forms, 30-minute insurance calls, missing documents, and frustrated patients. We're changing that. Our AI-powered automation platform handles intake, benefits verification, documentation, and even calls payers and patients—so practices can focus on care, not chaos. We're live with some of the largest healthcare providers in the U.S., growing fast, and backed by world-class investors like Y Combinator, Liquid 2 Ventures, Funders Club, Wisdom Ventures, and incredible founders & operators including Immad Akhund (Mercury), Sebastian Mejia (Rappi), and Bradley Horowitz (Google VP Product). What You’ll Do Build and maintain end-to-end features across the stack using Next.js on the frontend and FastAPI, NestJS, or similar backend frameworks. Develop and manage robust prompt libraries for production-grade LLM agents, with clear documentation, version control, and optimization strategies. Run A/B tests on prompts to improve accuracy, task completion, and agent behavior across various healthcare workflows. Architect scalable automations with n8n, and integrate with EHRs, VOIP systems, faxes, Gmail, and other healthcare infrastructure. Manage messy, real-world healthcare data pipelines with grace and resilience. Continuously iterate on evals, model performance, and the real-world accuracy of our AI agents. Ship fast and often—your work will be in the hands of real users immediately. Deploy the product within Clinics & Leading Healthcare providers across US. Collaborate directly with founders, product, and customers to design and launch mission-critical features. Help shape the company’s future—team, culture, and product—from the ground up.

You Might Be a Fit If You... Have 3+ years of experience in AI/ML engineering, full-stack engineering, or both. Are comfortable building full-stack products from scratch and taking ownership across frontend, backend, and AI systems. Have strong prompting experience—including prompt engineering, prompt management, and A/B testing of LLM behaviors in production. Have worked with tools like LangChain, vector DBs, n8n, OpenAI, Claude, Gemini, ElevenLabs, Deepgram, and are always exploring new ones. Have experience with complex system integrations (EHRs, VOIP, external APIs) and love making messy systems talk to each other. Thrive in ambiguity and love turning raw ideas into real-world impact. Are fast, scrappy, and value getting something working over chasing perfection. Are obsessed with speed, ownership, and building things that actually matter.

This Isn’t a 9–5 We’re not building a chill agency tool or another SaaS dashboard. We’re rebuilding the infrastructure of healthcare. This is for builders. For hackers. For people who want to grow fast, take ownership, and maybe even build the next company after this one. You’ll work hard, learn fast, and help conquer the f*cking world with us.
