Senior Software Engineer (Backend/Full Stack)

About the role

Our mission is to make enterprise procurement effortless.

Technology is one of the biggest line items in any enterprise budget, yet buying it still means months of back-and-forth across Finance, Legal and IT. Vertice is the AI procurement platform changing that. Our agentic workflows, autonomous negotiation agents, and expert buyers help finance and procurement teams in 100+ countries buy smarter and save money. Customers including ARM, Brex and Santander rely on us, and with over $75bn in spend processed, we consistently deliver 20%+ savings while cutting procurement cycles in half. The market momentum has been unprecedented, and in 2026 we were named #1 in B2B software and third overall in the Deloitte UK Technology Fast 50.

We were founded by Roy and Eldar Tuvey, serial entrepreneurs who have already built and exited two category-defining companies, and we’re backed by $100M+ from investors including Bessemer Venture Partners.

We’re a team that values candour and moves fast. Every permanent employee holds equity, so you share directly in what we build. If you’re looking for a comfortable 9-to-5, we’re probably not the right fit. If you want to do the best work of your career, we’d love to talk.

As part of our team, you’ll have the chance to work with

- React & TS for a front-end development

- Purely serverless infrastructure and architecture

- AWS Lambda microservices written mostly in Python

- Various AWS services including AWS Dynamo, Glue, StepFunctions, Athena, Timestream…

- REST and GraphQL APIs

- Automation in Python and Behave for Integration tests and Python + Playwright for UI tests

- … and many others. We follow trends and take an open-minded, pragmatic approach to finding new solutions to problems.

How our Engineering Team operates

Collaboration and transparency are at the core of how we work. We keep it simple - no unnecessary management layers, just direct connections between business and engineering. Hierarchies don’t get in the way, instead - we keep things flat, flexible and focused on what works. This is how we do it:

- Autonomous Teams - Our small teams (made up of Frontend, Backend, Fullstack and QA) operate with Technical Leads and People Managers, each focusing on what they do best, while leaving enough space for everyone to make an impact. They decide how they work - whether it’s stand-ups, prioritization or project management methods. Teams are assigned areas/goals/problems where they can make the biggest impact, yet they don’t own any part of the code, so they can basically work on any part of the product.

- People Managers - You won’t be left figuring things out alone. Our People Managers with psychology backgrounds focus on your growth, well-being and career support while keeping Vertice’s flat, collaborative culture strong. They’re here to encourage open communication, support conflict resolution and help ensure you thrive.
