What You’ll Do:
  • Architecture & Delivery Design and implement scalable microservices and component-driven UIs using React 18+ and Node.js. Build resilient REST/GraphQL APIs; ensure schema/versioning discipline and backward compatibility. Drive cloud-native solutions (AWS/Azure/GCP) with IaC (Terraform/CloudFormation/Bicep).Ensure observability (logs, metrics, traces with OpenTelemetry), SLIs/SLOs, and error budgets.
  • Security & Compliance Apply OWASP Top 10 controls, secure coding, and token-based auth (OAuth2/OIDC/JWT).Implement data protection controls, encryption (in transit/at rest), and secrets management. Partner with Risk/Compliance on PCI DSS, SOC 2, GDPR/CCPA, and SOX alignment.
  • Quality & Performance Maintain high test coverage (Jest, React Testing Library, Cypress, Supertest).Optimize Core Web Vitals, server-side caching, and database/query performance. Champion accessibility (WCAG 2.1 AA) and localization/internationalization (including Spanish/Portuguese for LATAM).
  • Collaboration & Leadership Mentor engineers, conduct code/design reviews, and uplift coding standards. Collaborate with PM, Design, Compliance, and SRE to deliver outcomes on time. Break down roadmaps into increments; manage technical debt and production readiness.
Qualifications: (Must-Have)
  • 8+ years of professional software engineering; 5+ years in modern JavaScript/TypeScript.
  • Expert in React (Hooks, Context, Suspense), TypeScript, Node.js (Express or NestJS).
  • Strong with API design, authentication/authorization, and asynchronous patterns (queues, events).
  • Databases: SQL (PostgreSQL/MySQL) and NoSQL (MongoDB/DynamoDB/Redis); schema design and migrations.
  • Cloud & DevOps: AWS/Azure/GCP, containers (Docker), CI/CD (GitHub Actions/Azure DevOps/Jenkins), feature flags, blue green/canary deployments.
  • Testing & Quality: Unit/integration/e2e tests, contract testing (Pact), linting/formatting.
  • Security-by-design mindset and experience in regulated environments (BFSI/FinTech).
  • Communication: Able to translate complex tech into clear stakeholder language.
Nice to Have:
  • NestJS or Next.js (SSR/SSG), Webpack/Vite, Storybook/Chromatic.
  • Message brokers/streaming: Kafka, RabbitMQ, SQS/SNS.
  • Event-driven and CQRS/Saga patterns.
  • Kubernetes (EKS/AKS/GKE), service mesh (Istio/Linkerd).
  • Analytics & Monitoring: Datadog, New Relic, Prometheus, Grafana.
  • Experience with payments, KYC/AML, or core banking integrations.
  • Fluency in Spanish or Portuguese is a plus.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
