Senior Software Engineer

Join Bezos.AI as a Senior Software Engineer to build the platform powering global e-commerce fulfilment. Use Go, React, and AWS serverless in an AI-native, remote-first startup.

• 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
• 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
• Level up the team: Mentor other engineers through code reviews, pair programming and design discussions, and help shape our engineering culture and best practice
• 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

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

• 25 days holiday + 8 bank holidays
• Mental health support through Spill, and a free Headspace subscription
• Remote-first team
• Real ownership and unusually fast scope
• An AI-native engineering culture where building with AI is the default, not an experiment
