Senior full stack engineer (contractor)

What we're looking for We’re looking for a founding engineer who wants to build, ship, and scale with us. You’ll be one of our first engineers, working directly with the founders to deliver the core product. We have a clear vision and roadmap — now it’s about execution and persistence. You’ll take on meaningful ownership across the stack (React/Next.js, Python, PostgreSQL) and help us move fast while keeping our systems solid and secure. We’re a small, focused team (currently under five people), and this role will have a direct impact on product direction, architecture, and early engineering culture. You’ll collaborate closely with product and design to build intuitive, reliable interfaces and AI-driven workflows that genuinely help people. Responsibilities Own major features end-to-end. From design discussions to production deployment. Build across the stack. Frontend, backend, and everything in between. Instrument and learn. Use metrics and user feedback to refine what we build. Shape the foundation. Influence architecture, tools, and engineering practices. Keep security and ethics front and center. We’re handling sensitive healthcare data — trust is everything. We’re tackling complex engineering problems — building intelligent systems that can understand messy, real-world healthcare data, automate workflows, and communicate with empathy and reliability. Qualifications You’ve spent ~5+ years building and shipping production-grade software. You’re fluent in React/Next.js , React Native Python , and PostgreSQL , or can ramp up quickly. You’re an “A-player”, builder who loves solving problems, not just following specs. You are familiar with the AI tools and use them on day-to-day to multiply your productivity. You balance speed and quality — you know when to ship and when to refactor. You’re comfortable working in a small, fast-moving team where priorities evolve, but the direction is clear. You are available in a live zoom call during business hours to enable rapid iterations and learning. You care about doing the right thing for users, especially when it involves their health or privacy. Why join us Mission with meaning. We’re building something that makes healthcare a little less painful for real people. When we get it right, we help someone when they need it most avoid thousands in unnecessary medical costs — or get care they might otherwise miss. High ownership. You’ll shape the product, stack, and early engineering culture. Learn fast, build fast. We believe in experimentation, measurement, and steady improvement. Grow with us. You’ll be part of the team that takes Mira Mace from idea to scale. About Us At Mira Mace, we’re building an AI-powered healthcare assistant that helps people navigate one of the most confusing systems out there. We’ve felt the pain ourselves — the endless back-and-forth with insurance, surprise bills, and the lack of clarity when you just need answers. Too many people fall through the cracks, and we’re determined to change that. Our goal is simple: give people a trusted advocate who can make healthcare less exhausting and more human. Our founding team brings a mix of strong technical experience from companies like Microsoft, Google, and Meta , along with serial startup experience ranging from early bootstrapped ventures to Series D scale-ups. We’re early, focused, and building with urgency and care.
