Our requirements
- Solid TypeScript/JavaScript fundamentals with substantial experience delivering and operating customer-facing mobile or web applications.
- Production depth in Node.js and at least one major product surface (such as React Native or Next.js).
- Working knowledge of APIs, data modeling, asynchronous workflows, testing, and cloud deployment (GCP preferred).
- Ability to read, extend, and troubleshoot Go and Python microservices.
- Clear written and spoken English, dependability in a remote team, and a direct, low-ego approach to problem-solving.
Optional
- Experience with media-heavy consumer products, social/community systems, creator platforms, or in-app purchases.
Your responsibilities
- Deliver and own features across React Native, Next.js, NestJS, TypeScript, Go and Python microservices, and GCP.
- Diagnose and improve real product workflows spanning UI, APIs, data, media, background processing, and third-party services.
- Strengthen the media lifecycle—including capture, upload, processing, playback, analysis, retrieval, and failure recovery—across mobile and web.
- Use AI tools (e.g., Gemini, ChatGPT) as an active engineering partner for coding, testing, debugging, and documentation—verifying outputs rather than relying on it as a simple answer machine.
- Write maintainable code, focused tests, useful instrumentation, and concise documentation.
