Backend Engineer

• Collaborate with cross-functional teams to translate requirements into well-designed features for our mobile app.
• Design, develop, and test complex features, prioritizing scalability, performance, and a smooth user experience.
• Own the end-to-end technical delivery of multi-sprint initiatives, from architectural design through production release and post-launch monitoring.
• Make architectural decisions that improve modularization, maintainability, and long-term system reliability.
• Create reusable, scalable components and establish patterns that become standards for the team.
• Optimize performance to ensure quick and responsive user interactions, even under high-load scenarios.
• Implement robust security measures for data protection and compliance.
• Improve observability by defining monitoring standards, dashboards, alerts, and failure-handling strategies.
• Lead refactoring efforts to reduce technical debt and increase development velocity.
• Drive improvements in CI/CD pipelines, automation, and testing practices to ensure safe and efficient releases.
• Conduct rigorous testing and define quality standards for complex features.
• Integrate mobile apps with backend APIs in coordination with backend engineers, ensuring stable and well-defined interfaces.
• Identify risks early, propose mitigation strategies, and balance trade-offs between delivery speed and long-term maintainability.
• Participate in roadmap discussions by assessing technical feasibility, dependencies, and architectural impact.
• Act as a technical reference within the team, guiding design discussions and resolving complex engineering challenges.
• Participate in code reviews to uphold quality, provide coaching-level feedback, and elevate team standards.
• Support cross-functional troubleshooting, lead incident resolution when needed, and ensure long-term fixes are implemented.
• Mentor and support other engineers to raise overall team capability and engineering excellence.

• Spend a meaningful proportion of your time learning our COBOL core in structured sessions with our senior platform engineer. This is protected time, treated as part of the role, not something you do around other work.
• Contribute to modern Go services in the stack from week one, on scoped pieces of work that build context without putting you on the critical path.
• Help us document what you’re learning as you learn it. Fresh eyes are uniquely valuable for surfacing the things long-tenured engineers no longer notice.
• Pair with the existing team across the stack to understand how Go services, the COBOL core, and the surrounding tooling actually interact in production.
• Use AI tooling deliberately as part of how you learn: to summarise unfamiliar code, surface questions for your mentor, and turn what you learn into clear documentation faster than fresh eyes could alone.
• Take ownership of meaningful work across both the modern and legacy halves of the platform, with growing autonomy.
• Help repair and modernise core engineering processes: testing, deployment, definition of done, and the way work flows from support into engineering.
• Contribute to the broader modernisation program: knowledge capture, internal AI tooling, and the eventual decomposition of the platform into smaller, more approachable modules.
• Lead AI-assisted modernisation of the parts of the core you have come to understand, translating well-understood COBOL into well-tested modern services, with AI as a lever rather than a crutch.
• Own projects end to end. Work starts from a client-facing Design Doc that describes data flow and outcomes but not detailed technical specs; from there you own the technical design, the implementation, your own alpha testing, and everything in between.
• Adapt to the business. Priorities can shift at short notice when urgent client issues arise, and you will be expected to flex with them.
• Mentor the next Go-into-COBOL hire as the team grows.

• 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.
