About The Position

At Bezos, our vision is to Deliver Happiness - for our team, for end consumers, for the e-commerce brands we serve, and for our logistics partners. We're the managed global fulfilment partner for scaling e-commerce brands: one platform and one team handling fulfilment across a global fulfilment network, spanning the UK, Europe, North America and Australia. We give growing brands enterprise-grade logistics without the enterprise-grade complexity. We're a fast-moving, AI-native, Series A startup that will almost double our business in 2026 - and the platform that makes it all run is exactly what you'll build. The Mission: What You Will Achieve You'll become a cornerstone of our engineering team and help build the platform that powers global fulfilment - orders, inventory, shipments and returns flowing across our network every day. Reporting directly to the Head of Engineering, you won't just write production-grade code: you'll own core services end-to-end, mentor other engineers, influence the big technical decisions, and help shape how we build. We're genuinely AI-native and we expect our engineers to build with AI every day. This is a hands-on, high-impact seat in a small team where one exceptional engineer changes the trajectory of the whole business.

Requirements

• 2+ years in a senior software engineering role, ideally in a startup environment
• Strong backend fundamentals and deep commercial experience with Go - or a strong systems background in another language and the drive to master Go fast
• Extensive experience with AWS, event-driven architecture and serverless infrastructure like AWS Lambda
• Fluent designing and building RESTful APIs, with a solid grasp of microservice and serverless architectures
• AI-native - you already use AI-powered dev tools (Claude Code, Cursor, Copilot) and are genuinely excited to build with them every day
• A pragmatic builder with a knack for simplifying complex systems and shipping scalable solutions
• A product-oriented mindset - you care deeply about solving real user problems, not just shipping output

Nice To Haves

• Strong React / front-end experience
• Terraform or other infrastructure-as-code
• E-commerce, logistics or supply-chain exposure
• Experience mentoring engineers or leading technical projects

Responsibilities

• Build the core platform. Design, develop and maintain scalable, secure services and APIs in our serverless cloud environment, predominantly in Go and React.
• Own it end-to-end. Take domain-specific services from architectural design through to deployment, monitoring, and investigating and fixing the root causes of issues - you build it, you run it.
• Build with AI. Use modern AI-powered dev tools (Claude Code, Cursor, GitHub Copilot) every day to ship faster, and help set the standard for how we engineer with AI.
• Champion engineering excellence. Raise the bar on development workflows, testing, deployment and observability. Release small, fast and often - and keep the code simple, because the best code is the code you don't have to write.
• Level up the team. Mentor other engineers through code reviews, pair programming and design discussions, and help shape our engineering culture and best practice.

Benefits

• Build the core platform that powers global fulfilment
• Real ownership and unusually fast scope - a hands-on software developer role where you can shape your career path
• An AI-native engineering culture where building with AI is the default, not an experiment
• Remote-first team, meeting in person a couple of times a month
• 25 days holiday + 8 bank holidays
• Mental health support through Spill, and a free Headspace subscription
