Tech organization that designs, builds, and delivers both platform capabilities and product features that power Prose's personalized beauty experience — from the consultation and e-commerce journey to the manufacturing systems that turn every order into a physical, made-to-order product in our NYC and LA facilities. We are a deliberately compact, senior engineering team. Every engineer owns a broad scope, ships to production continuously, and works with AI-augmented development practices as a core part of the craft. You'll join at a moment where we're evolving toward a modular architecture with clearly separated domains, and you'll have a real voice in those design decisions. Few engineering teams get to ship code that ends as a physical product formulated for one specific person. If you're passionate about end-to-end ownership, technical excellence, and building with the best AI tooling available, we'd love to hear from you. Responsibilities Build & Ship Design, build, and ship features end to end across our stack: Python/Django services and REST APIs on the backend, React applications on the frontend. Own quality on your scope: automated testing, peer review, observability, and production monitoring. Identify and address areas of technical debt, implementing improvements to enhance system performance and maintainability. Architecture & Technical Direction Contribute to our architecture evolution: domain boundaries, data schemas, event-driven patterns, and the tradeoffs of a platform serving both e-commerce and manufacturing. Participate in architecture discussions and system design decisions. Advance our AI implementation across the tech org: make AI-augmented development part of your daily practice, and help shape our agents, skills, and internal tooling rather than just consuming them. Collaboration & Impact Collaborate closely with product, design, data, and operations stakeholders to deliver high-quality features — our scope touches everything from checkout conversion to factory throughput. Bring visibility to ongoing work, risks, and dependencies. Mentor other engineers and raise the team's bar through design and code review. Contribute to technical documentation and knowledge sharing across the team. Requirements 5+ years of professional software engineering experience, with significant time on both backend and frontend
