📋 Description

• Design and implement backend-heavy features using TypeScript and Node.js; build and evolve REST APIs with focus on correctness, consistency, and clear boundaries between services • Work with SQL (PostgreSQL): data modeling, migrations, and consistency guarantees • Take full ownership of one or more services, from requirements and implementation to production support, and drive integration work with external partners (vendors, clients) when needed • Own production behavior: investigate incidents, debug API failures, analyze data issues, and apply reliability patterns (timeouts, retries, idempotency, graceful degradation) • Improve observability (logs, metrics, visibility into system behavior) and propose improvements where reliability, performance, or monitoring is weak • Participate in tech spikes: explore unclear problems and turn them into concrete technical plans • Collaborate with Product and EM to clarify requirements and reduce ambiguity early; contribute to technical discussions, raise risks, and explain trade-offs • Review code, mentor mid-level engineers, and contribute to React code when features require UI updates or customer-facing flows

🎯 Requirements

• 4+ years of professional software development experience • Strong backend expertise with TypeScript and Node.js • Real production experience: incidents, debugging, API failures, data issues • Experience owning a service end-to-end, from requirements to production support • Clear product-level architectural thinking: well-designed APIs, correct data boundaries, proper error handling, ability to reason about trade-offs • Understanding of microservice architectures and platform-level interactions • Strong knowledge of HTTP APIs, SQL data modeling, and common failure modes • Proficient daily use of AI coding tools (e.g. Claude Code), with the ability to review AI-generated code quickly and critically • Readiness to build deep working knowledge of crypto and stablecoin payments: prior crypto experience is optional, and deep on-the-job learning of the domain is a mandatory part of the role • Ability to work with ambiguity: ask the right questions and structure unclear problems, working independently without overly detailed technical specs • High agency: you notice problems before they are assigned to you, raise risks early, and bring a proposed solution together with the problem • Strong written and verbal communication in English.
