Core Responsibilities

Primary Functions

Design, develop and maintain robust backend services and RESTful or gRPC APIs in Go, ensuring performance, maintainability and scalability.
Implement and optimise concurrency models using goroutines, channels and sync primitives to deliver high‑throughput, low‑latency systems.
Build and maintain microservices architectures in Go: service decomposition, independent deployability, communication patterns and modular design.
Integrate with SQL and NoSQL databases (e.g., PostgreSQL, MySQL, MongoDB, Redis), designing data access layers, optimising queries and supporting large‑scale data processing.
Collaborate with DevOps and infrastructure teams to containerise Go applications (Docker), orchestrate them (Kubernetes), and deploy via CI/CD pipelines.
Participate in architecture discussions, influence design decisions, propose improvements and choose appropriate frameworks/libraries to support Go‑based systems.
Write clean, idiomatic Go code, adhering to Go conventions, Go tooling (go fmt, go vet, golangci‑lint), and apply unit/integration/benchmark tests.
Monitor, profile and optimise application performance: address bottlenecks, memory leaks, race conditions and ensure efficient resource usage in production.
Troubleshoot production issues, debug complex scenarios, perform root‑cause analysis and resolve incidents affecting Go services.
Develop real‑time data processing pipelines, background jobs, event‑driven architectures with message queues or streaming services (Kafka, RabbitMQ, NATS) in Go.
Ensure system security, authentication/authorization (OAuth2/JWT), data encryption, secure communication and compliance for services built in Go.
Maintain code repositories (Git), conduct code reviews, mentor junior team members, and help foster a culture of craftsmanship in Go development.
Create and maintain technical documentation: API specs, architecture diagrams, deployment run‑books, performance guidelines specific to Go services.
Stay up‑to‑date with the Go ecosystem, cloud‑native patterns, distributed systems trends and apply new tools/techniques to improve development efficiency.
Provide input into sprint planning, feature estimation, backlog prioritisation, agile ceremonies and coordinate with cross‑functional teams for timely delivery of Go‑services.
Collaborate with front‑end and product teams to define efficient API contracts, versioning strategy, service evolution and ensure seamless integration with Go‑based backend.
Lead efforts to modernise legacy systems by migrating to Go‑based microservices, reducing tech‑debt, increasing performance and maintainability.
Collect and analyse telemetry, logs, metrics from Go production systems, integrate monitoring (Prometheus, Grafana), alerting and drive improvements based on data.
Ensure coverage of unit/integration/benchmark tests in Go code, establish test automation and support high reliability of services built in Go.
Mentor peers and support the Go developer community culture within the organisation: conduct knowledge sharing, code sessions and help set Go engineering standards.

Secondary Functions

Support ad‑hoc data requests and exploratory performance analytics for Go‑based services, logs or backend systems.
Contribute to the organisation’s backend engineering roadmap and Go‑platform strategy: middleware, service mesh, observability.
Collaborate with business units (product, operations, analytics) to translate backend service needs into engineering tasks and prioritise accordingly.
Participate in agile ceremonies (sprint planning, stand‑ups, retrospectives) within the engineering team.

Required Skills & Competencies

Hard Skills (Technical)

Expert proficiency in Go programming language, including packages, modules, idioms and concurrency patterns (goroutines, channels).
Solid experience in designing and developing RESTful APIs and/or gRPC services in Go.
Hands‑on experience with microservices architecture, containerisation (Docker), orchestration (Kubernetes) and cloud‑native deployments.
Strong working knowledge of databases (SQL and NoSQL) and data‑access patterns for performance in Go applications.
Proficiency in testing and benchmarking in Go (unit tests, integration tests, performance tests).
Experience with message/event‑driven systems, streaming or background job frameworks in Go (Kafka, RabbitMQ, NATS).
Familiarity with observability, profiling and monitoring tools (Prometheus, Grafana, pprof) for Go applications.
Solid understanding of secure coding practices, authentication/authorization, encryption and production‑grade reliability in Go services.
Proficiency with version control (Git), code review processes and building CI/CD pipelines tailored to Go codebases.
Ability to work with cloud platforms (AWS, GCP, Azure), service deployment, infrastructure as code and Go service scaling.

Soft Skills

Excellent communication and collaboration: capable of working with designers, engineers, product owners and stakeholders to deliver end‑to‑end solutions.
Strong analytical and problem‑solving mindset: able to diagnose complex concurrency, performance or distributed systems issues and implement corrective action.
Ownership and accountability: responsible for quality, reliability and delivery of Go services from conception through production.
Adaptability and continuous learning: keep abreast of Go ecosystem, distributed systems, cloud technologies and best practices.
Time‑management and prioritisation: manage feature work, bug‑fixing, tech‑debt reduction and production support in parallel.
Mentorship and team‑player: assist less experienced developers, conduct reviews, share Go best practices and help build team capability.
User‑centric thinking: understand business and end‑user requirements, translate them into performant backend services that meet their needs.
Quality mindset: focus on maintainable, testable and high‑performance code rather than quick fixes or short‑term hacks.
Strategic mindset: align service development with business goals, scalability concerns, engineering roadmap and technical debt trade‑offs.
Attention to detail: ensure code correctness, service reliability, resource usage, concurrent handling and production stability.
