Staff Software Engineer (Voice AI Platform)

The Mission "Leading healthcare into the agentic era." Every day, millions of patients sit on hold just to schedule an appointment, ask a billing question, or get a prescription refill. The front desk of a specialty clinic is a high-stakes environment where every missed call or delayed refill impacts patient care. It’s broken. We’re fixing it. Taxo builds the definitive Voice AI agent for specialty healthcare — handling patient intake, complex scheduling, prescription refills, and triage with human-level nuance. Our agents integrate deeply with EHR/PMS systems and are tailored to each provider’s unique clinical workflows, so patients get fast, accurate answers instead of hold music. The Opportunity: From 0 to Global Scale We aren’t just “testing the waters.” We’ve secured major agreements with conglomerate healthcare groups across the US, UK, and KSA. The demand is massive, the contracts are signed, and we need to build — fast. As our Founding Engineer, you won’t just be writing code — you’ll be architecting the backbone of a global healthcare platform. You’ll have a massive stake in the product direction, the culture, and the technical legacy of Taxo. What You’ll Do • Ship 0 → 1: Transform complex healthcare workflows into seamless, automated voice experiences. Design, build, and scale the core voice AI platform from real-time speech processing to intelligent call routing. • Architect for Scale: Build systems capable of serving hundreds of thousands of patients across three continents. Own the infrastructure that makes sub-second response times possible at global volume. • Product Engineering: Act as a true partner in product discovery — knowing when to build for perfection and when to ship for speed. Collaborate directly with the founder and healthcare professionals to translate complex clinical SOPs into intelligent agent behaviors. • Integrate Deep: Develop and fine-tune integrations with EHR/PMS systems, ensuring seamless data flow between our voice agents and provider systems. • Set the Standard: Establish engineering best practices, from CI/CD pipelines to AI integration patterns. Build for HIPAA, SOC 2, and the operational rigor that healthcare demands. • Shape the Company: Influence engineering culture, hiring, and technical standards as the team grows around you. The Stack We move fast with a modern, scalable toolkit: • Frontend: React, Next.js • Backend: Node.js (TypeScript) • Data & Infrastructure: Postgres, Redis, AWS, Terraform • Intelligence: Leading-edge LLMs and Voice AI integration Who You Are • The Veteran: 5+ years of experience building production software, with a demonstrated track record of impact at a top-tier tech company or high-growth startup. You’ve lived through the chaos and you thrive in it. • The Architect: You’ve built at scale before. You understand the nuances of serving large enterprise clients and high-volume end-user bases. You can design, build, and scale production-grade distributed systems. • The AI Enthusiast: You stay current with AI/ML developments and are excited to implement them in practical, high-impact ways. Experience with voice, NLP, conversational AI, or real-time audio/speech systems is a major plus. • The Owner: You are opinionated about code quality and user experience. You don’t need a roadmap — you help draw it. Comfortable with rapid iteration, experimentation, and learning from failure. • Bonus: Experience with telephony systems (SIP/VoIP), healthcare data standards (HL7/FHIR), or HIPAA-compliant infrastructure. Why Taxo We are solving a trillion-dollar problem in one of the world’s most essential industries. With global enterprise backing and a clear path to expansion, this is a rare chance to join as a founding member with “day one” impact and “year five” stability. • 💰 Founding-Level Equity — 0.5–2%. You’re not joining a team, you’re building a company. Your stake reflects that. • 🧠 Frontier AI Work — Voice agents, real-time inference, healthcare-grade accuracy. This is the cutting edge. • 🏥 Impact That Matters — Every feature you ship directly improves how millions of patients access care. • 💻 Competitive Compensation — Including health coverage, unlimited PTO, and the flexibility to do your best work. • 🌍 Global From Day One — US, UK, and KSA operations. Build for the world, not just one market. How We Work Taxo is a small, fast, high-conviction team. We don’t do bureaucracy. We don’t do “that’s not my job.” We believe the best products are built by people who care deeply about the problem, move with urgency, and hold themselves to an impossibly high standard. If you want to be a founding engineer at a company that’s changing how healthcare works — we’d love to hear from you.
