Backend Engineer

• Design, build, and maintain Go microservices (HTTP APIs, sidecars, and background processors) that handle payment authorization, tokenization, settlement, and reporting.
• Write clean, well-tested Go: table-driven unit tests, mocked dependencies, and meaningful coverage on the paths that move money.
• Profile and tune services for high throughput and low latency (pprof, benchmarking) — transaction paths are latency-sensitive.
• Integrate with relational and NoSQL data stores (MySQL, DynamoDB, PostgreSQL); design schemas, access patterns, and migrations that hold up under load and evolve safely.
• Build and consume internal service APIs, including service-to-service authentication and shared platform libraries.
• Containerize services with multi-stage Docker builds and ship them through CI/CD pipelines to cloud infrastructure.
• Integrate with third-party payment processors and AWS services, handling sensitive data in line with PCI DSS and our security standards (secure coding, data masking, TLS, secrets management).
• Build reliability into money-movement flows: idempotency, retries, and reconciliation/settlement correctness.
• Participate in code review, design discussions, on-call rotation, and incident response for the services you own.
• Use AI-assisted development tools (e.g., GitHub Copilot, Claude Code, Cursor) effectively and responsibly as part of day-to-day work.
