Senior Software Engineer

About Us

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.

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.

• Get to know the platform end-to-end and ship your first production code in your opening weeks
• Take ownership of a domain-specific service, from design through to deployment and monitoring
• Establish your AI-assisted engineering workflow and share what's working with the team
• Start raising the bar through code reviews, pairing and design discussions

• Core Language:
  Go, React
• Cloud Provider: AWS (Lambda, SNS, SQS, S3, EC2, Cognito, Cloud Watch)
• Database:
  PostgreSQL
• Infrastructure as Code:
  Terraform
• Architecture: event-driven, serverless-first microservices

Non-Negotiables:

• 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

Bonus Points (Nice to Have):

• 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

• 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
