About the role

Key responsibilities & impact

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

What you’ll need

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.
