Fijoya- Senior Full Stack Engineer

Description Fijoya is seeking a senior full-stack engineer who's as comfortable architecting systems as they are shipping polished mobile experiences. Why You? You've been around the block. You've built, shipped, and scaled — and you know the difference between code that works and code that lasts. You take ownership, move fast without breaking things, and make the engineers around you better. Your Role: Own features end-to-end: You’ll lead the design and development of core product features across our apps, LLM-powered experiences, fintech workflows, and web app — from architecture decisions to pixel-level UX polish. Full-stack depth: Build and own cloud-based, serverless backend services that power the product. You'll define the contracts between client and server, not just consume them. Set the bar: Your code, reviews, and architectural decisions become the standard. Junior engineers will learn from you. Shape the roadmap: You'll partner with Product and UX as a technical co-author of the product direction — not just an executor. Requirements What You Bring: 5+ years in software engineering, with meaningful time building production-grade applications. React is your wheelhouse — you've shipped apps to the App Store and/or Google Play, dealt with native modules, handled offline states, optimized render performance, and debugged the gnarly stuff. Strong proficiency in React, Node.js, and TypeScript across the stack. Deep experience with serverless cloud architectures on GCP or AWS. Solid grounding in databases — PostgreSQL, Firestore, MongoDB, or similar. A track record with CI/CD pipelines, automated testing, and engineering hygiene that keeps teams moving fast. Strong communication skills — you can explain tradeoffs to a PM, a founder, and a junior dev in the same conversation. What Sets You Apart: You've architected systems from scratch and lived with the consequences — good and bad. You have strong opinions about mobile UX and the taste to back them up. You've thrived in early-stage startup environments where the map doesn't exist yet. Bonus: experience in digital health, regulated industries, or real-time data. Why This Role: This is a foundational engineering hire at a stealth-stage company backed by Team8, one of the most active deep-tech venture firms in Israel. You won't be building features for a backlog — you'll be building the thing.
