Capa is a B2 B fintech infrastructure company built to make money movement across Latin America fast, simple, and compliant. We give fintechs and financial operators a single, reliable channel to move pesos and other currencies across the region in real time.

Tareas Responsibilities
  • Own a backend service (Nest JS/Type ORM/Postgres) or frontend module (React/Vite/Tan Stack) end-to-end, from design through production
  • Design for money-critical correctness: idempotency, race conditions, reconciliation-safe state transitions
  • Write integration tests against real Postgres (Testcontainers), not just mocked unit tests, for anything touching money flows- Own AWS infra changes via CDK for the services you own
  • Design and review API contracts (Nest JS + Swagger) and shared Type Script types across services
  • Own QA for your own features end-to-end — write and execute the test plan, cover edge cases
  • Mentor Mid/Junior engineers; review PRs; raise the team's code-quality bar
  • On-call capable for money-critical paths
  • Partner with product/compliance on ambiguous, cross-cutting problems (KYB, FX, settlement)
Requirements
  • 5+ years professional software engineering, strong Type Script across backend and frontend (or deep on one side, fluent on the other)
  • Backend: Node.js + Nest JS (or a comparable opinionated framework), an ORM (Type ORM), Postgre SQL, REST API design- Frontend: React, modern data-fetching (Tan Stack Query or equivalent), component-driven development
  • AWS fundamentals: Lambda, IAM, KMS, S3, SQS/SNS; comfortable reading/writing CDK or another Ia C tool
  • Testing discipline: understands why integration tests against a real DB matter when correctness has financial consequences
Nice-to-haves
  • Fintech/payments/crypto experience (FX, cross-border settlement, ledger/reconciliation, KYC/KYB)
  • Datadog or comparable observability experience- i18next / multi-market Lat Am product experience
  • Radix/shadcn-style design systems + Tailwind
