Staff Backend Developer - Golang

The candidate will have responsibilities across the following functions:

Domain and Architectural Leadership:

• Deeply understand core financial domains (card issuance, payments orchestration, remittance, ledger systems) and translate this knowledge into resilient bounded contexts, canonical data models, and API standards.
• Define and own the long-term backend architecture roadmap, ensuring coherence across microservices and shared infrastructure.
• Champion clean architecture and Domain-Driven Design (DDD) principles, owning complex cross-domain decisions (e. g., transaction reconciliation, settlement workflows).
• Serve as the architectural authority in design reviews, incident postmortems, and roadmap discussions.

Engineering Excellence and Quality:

• Lead the engineering excellence charter, establishing organisation-wide guidelines for code quality, testing, CI/CD, and security hygiene.
• Define and continuously track key engineering KPIs (e. g., Service SLAs, MTTR, Deployment Frequency) to quantify and improve outcomes.
• Mentor technical leads and senior engineers, raising the overall engineering bar and enabling Generative AI-assisted engineering workflows responsibly.

Hands-on Technical Contribution:

• Architect, prototype, and profile Go-based distributed services for high-throughput, low-latency financial flows.
• Apply expert knowledge of Go's concurrency, synchronisation, and runtime tuning to design performant and scalable services.
• Lead postmortems, fault-injection sessions, and conduct deep-dive performance tuning using tools like $pprof.

Stakeholder Collaboration and Influence:

• Partner closely with Product, Compliance, Risk, and Business teams, translating functional requirements into resilient technical designs.
• Represent engineering trade-offs in executive forums and lead major cross-functional initiatives (e. g., multi-region rollout, PCI-DSS compliance).
• Maintain technical debt registers and remediation plans, acting as the technical conscience to balance delivery pace with operational integrity, security, and auditability.

Requirements:

• 8-12 years of backend engineering experience, with at least 5 years in Go in high-scale, distributed systems.
• Proven experience architecting and scaling financial systems (payments orchestration, card processing, or ledgering).
• Expert understanding of Go concurrency, synchronisation, and runtime tuning.
• Strong grounding in relational data design (PostgreSQL/MySQL) and event-driven patterns.
• Practical knowledge of security, encryption, and compliance standards (PCI-DSS, MAS, ISO 27001) in a regulated fintech environment.
• Experienced in observability and SRE practices (Prometheus, OpenTelemetry, Grafana) and capacity planning.
• Demonstrated ability to mentor senior engineers and influence technical direction at scale, including articulating complex issues to all organisational levels.
• Familiarity with IaC, Kubernetes, service mesh, and API gateways.
• Experience with AI-assisted engineering tools (e. g., Copilot, CodeWhisperer) is a plus.
