• Own end-to-end feature delivery for the Wallet, Billing & Taxes platform – from API design and backend implementation to necessary Vue.js frontend changes. • Build and maintain highly stable, performant, and scalable backend services using Node.js, MongoDB, and distributed systems patterns. • Identify and fix systemic issues (crashes, time-outs, race conditions, memory leaks, etc.) to improve overall platform reliability. • Drive performance optimizations and cost-efficiency improvements (query tuning, caching strategies, indexing, reducing cloud spend). • Actively reduce technical debt by refactoring critical parts of the codebase, improving test coverage, and eliminating anti-patterns. • Implement and enforce security best practices (input validation, auth flows, secrets management, rate limiting, etc.) in every change. • Enhance observability – add meaningful logs, metrics, alerts, and tracing to make issues easier to debug in production. • Collaborate closely with QA from day one: review test cases, perform live demos during QA handover, and quickly address feedback. • Contribute to internal tooling and automation that speeds up development and deployment cycles. • Pair with other engineers, share knowledge, and help unblock teammates when needed. • Participate in on-call rotation and resolve production incidents for the services you own. • This is a hands-on IC role where you’ll write a lot of production code, ship frequently, and directly impact the stability and scalability of our Wallet platform.
