Description

About Us Gramian Consultancy is a boutique consultancy specializing in IT professional services and engineering talent solutions. 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 Migrate and refactor existing Python logic into Golang services owned by various other teams. Rapidly learn and adapt to internal tools, systems, and processes to speed up migration. Collaborate closely with engineers across teams to ensure smooth delivery. Debug complex issues quickly and provide clear, actionable solutions. Maintain high-quality, well-tested code with thorough validation. Identify and implement improvements in our migration tooling. 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. 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.

Responsibilities

The role focuses on migrating and refactoring existing Python logic into Golang services within a large-scale B2C environment. Responsibilities include diagnosing performance bottlenecks, improving system architecture, and collaborating cross-functionally to ensure smooth delivery.
