With a strong background in software engineering and leadership, we help companies build high-performing teams by matching them with professionals who truly fit their needs. Role overview We’re looking for a Senior Backend Engineer who thrives in large-scale B2C environments and prefers Golang as a main language . You’ll join an established product engineering team building the backend for a user-facing product , with a strong focus on latency, scalability, reliability, and data-intensive troubleshooting . This role is ideal for someone who enjoys owning complex backend problems end-to-end: from system design and performance investigations to improving architecture, strengthening testing practices, and leading legacy migrations (including Python → Go endpoint migrations). About the Team You will work with an existing engineering team and contribute to the technical direction of both the product and the team. The team operates in a modern product delivery model and collaborates closely with Product and Design. You’ll participate in the team’s organizational processes— planning, backlog refinement, sprint reviews —and help ensure we’re building the right things in the right way. We need someone who can: • Understand and troubleshoot data-intensive systems • Diagnose performance bottlenecks • Proactively identify technical risks and help guide solutions • Communicate clearly across engineering, product, and design Key Responsibilities • System Design: Design and evolve backend systems with a strong emphasis on low latency , scalability , and operational robustness. • Backend Development: Build and maintain services primarily in Golang , with some existing systems in Python ; contribute to ongoing Python → Go migrations . • Architecture & Reliability: Work within a distributed system stack including Kubernetes , Kafka , PostgreSQL , Redis , and observability tooling (internal metrics/alerting + Grafana dashboards). • Quality Engineering: Apply strong testing practices, clean architecture principles, SOLID , and proven design patterns to keep systems maintainable and safe to change. • Cross-Functional Execution: Partner with Product, Design, and Engineering counterparts to deliver features aligned with product and business strategies. • Communication & Planning: Provide technical insight in reviews and team meetings; help scope, estimate, and prioritize work across competing needs. • Proactive Problem Solving: Identify bottlenecks early, address technical debt thoughtfully, and improve system performance and developer experience. • 5+ years of professional backend engineering experience , building, shipping, and operating production systems. • Proven experience working on large-scale B2C applications (high traffic, high availability, performance-sensitive systems). • Golang as a primary language in recent roles, with demonstrated ownership of production services (design, development, deployment, and on-call/support as needed). • Strong system design skills with a focus on latency, scalability, reliability, and maintainability . • Experience building and supporting data-intensive systems , including troubleshooting performance bottlenecks and production issues. • Hands-on experience with modern backend infrastructure and tooling, including: • Kubernetes (deployments, scaling, operational workflows) • Kafka (event-driven patterns, consumer/producer behavior, reliability considerations) • PostgreSQL (schema design, query optimization, indexing, performance tuning) • Redis (caching strategies, performance, TTLs/invalidation concepts) • Observability/monitoring and dashboards (metrics/alerting + Grafana ) • Strong engineering fundamentals: testing practices , clean code, SOLID principles , and common design patterns . • Comfortable collaborating cross-functionally with Product and Design; able to communicate technical tradeoffs clearly and help scope and prioritize work. #J-18808-Ljbffr Apply tot his job
