The company:

One of our long-standing clients in the US logistics technology space. They run a high-volume operational platform built on cloud-native, event-driven foundations, and they are continuing a multi-year push to modernise their backend stack.

Role and Responsibilities:

You will sit on a senior backend team owning core Go services that move large volumes of operational data through gRPC APIs and Kafka pipelines on AWS. The work spans system-level design decisions, performance tuning under sustained load, and lifting standards across the wider engineering org through reviews, mentorship, and architectural input. This is a hands-on senior seat — you will be writing code, but you will also be a technical reference point for engineers outside your immediate team.

• Design and ship production Go services that run reliably at scale
• Own the backend API surface — gRPC contracts, message schemas, versioning
• Build and tune Kafka-based event pipelines (producers, consumers, ordering, replay)
• Build on AWS with a serverless-first lean where it makes sense, using the AWS SDK for Go
• Review code, mentor mid-level engineers, and shape engineering standards
• Drive incident retrospectives and feed the lessons back into platform practice

Job Requirements:

• At least 5 years of production Go in a backend or distributed-systems role
• gRPC, including schema design and breaking-change management
• Kafka in production — not passing familiarity
• AWS, with hands-on experience using the AWS SDK for Go
• Comfortable owning service design end to end and influencing engineers outside your team

Nice to Have:

• Exposure to AI/ML integration in backend services
• Background in logistics, freight, supply chain, or other high-throughput operational platforms
