We're looking for high-horsepower, mission-driven people who find it unacceptable that the female body is still a medical mystery — and want to help change that. ABOUT THE ROLE We're hiring a Senior Software Engineer to join the product engineering team. You'll architect, build, and scale our personalized vaginal health platform, from ideation to launch and well beyond. This is a role for someone who wants to build something great, not just ship tickets. You'll own features end-to-end, work across the full stack, partner closely with product, ops, clinical, and design, and help shape the way we engineer as we scale. This is a role for someone who is product-minded, relentlessly driven, and exceptionally resourceful. Evvy is a primarily in-person team based in New York, NY. Given the cross-functional nature of this role, our ideal candidate is located in NYC. WHAT YOU'LL DO - Lead zero-to-one product development from ideation to production, collaborating with cross-functional leaders across data, product, design, marketing, clinical, and operations - Work across the true full stack: requirements definition, system architecture, backend, frontend, QA, monitoring, debugging, maybe even the occasional Figma mockup - Collaborate closely with the team to refine our technical architecture and platform direction - Build innovative, personalized user experiences, from our AI-powered insights layer to ecommerce, testing services, and care delivery - Design and build internal workflows and tooling that allow our ops team to support users at every step - Make smart tradeoffs between speed and scalability, knowing when to ship something now that will eventually break (and understanding exactly where it will) vs. when to build it right the first time - Own your work all the way to outcome: you don't consider something shipped when the PR merges; you're eager to see how it does post-launch, notice any bugs in FullStory before anyone reports it, and close every loop - Shape our engineering culture & inspire how we work at Evvy: define processes, mentor teammates, and contribute to a innovative, high-performance team WHAT WE'RE LOOKING FOR Technical depth and practicality. You have 5+ years of full-stack experience with a proven ability to ship high-quality, scalab
