Project Responsibilities

• Build and maintain functionality in our React Native SDK, including brownfield integration into partners’ host apps.
• Design and implement supporting BFF endpoints in Node.js and TypeScript, exposed over RPC.
• Debug the full request path: mobile client, network, BFF, and external services.
• Review other engineers’ code and provide substantive feedback.
• Take part in production incident response, including analyzing logs and tracing issues back to their root cause.
• Make pragmatic technical decisions in the face of changing requirements and strict regulatory constraints

Must-haves

• 5+ years of commercial software development experience.
• Strong experience with React Native (both Expo and bare workflows, including native module integration).
• Strong TypeScript skills on both the client and server sides.
• Experience with Node.js BFFs (any modern framework: NestJS, Fastify, Hono, Express).
• Hands-on knowledge of designing RPC-style APIs.
• Solid SQL skills, including writing queries against materialized views. This role involves retrieving data both through RPC endpoints and directly via SQL.
• Comfortable working in Git-based workflows with code review as a core practice.
• Effective use of AI coding tools (Claude Code, Cursor, Copilot) in day-to-day work, with the judgment to know when to trust the output and when to verify it. REALLY IMPORTANT!
• English – Upper-Intermediate (B2) or higher.
• Product mindset: ability to understand business goals, drive feature delivery, challenge requirements constructively, and take ownership from idea to production.

Nice-to-have

• Experience with React Native brownfield integration (embedding RN code into an existing native host app).
• Experience in fintech, banking, or a regulated environment.
• Familiarity with OTA update tools (Stallion, Hot Updater, CodePush, Expo Updates).
• Experience with Go.
