Senior Software Engineer in Test

Vertice

Spend on technology is one of the biggest items in an enterprise CFO’s budget, second only to headcount. Traditional procurement is one of the most frustrating, friction-filled bottlenecks in modern businesses. A single purchase routinely stalls for months, drowning in endless email threads and dragging in teams from Finance, Legal, Security, and IT. Vertice is the world’s first Intelligent Procurement Platform aiming to eliminate this chaos. By combining automated agentic workflows, deep AI insights, and a global network of expert negotiators, we empower enterprises to buy smarter and scale at pace. The market response has been unprecedented: * $75bn+ in spend processed across our platform. * 20% savings consistently delivered to our customers. * 70% reduction in standard enterprise procurement cycles. * 13X revenue growth achieved over the last two years alone. Founded by serial technology entrepreneurs Roy and Eldar Tuvey, who have successfully scaled and exited two category-defining platforms and created $600M+ in enterprise value, we are backed by over $100M in Series C funding from tier 1 global investors including Bessemer Venture Partners, 83North, and Lakestar.

With headquarters in London and hubs in New York, Brno, Sydney, and Johannesburg, we are fundamentally reshaping the global B2B economy. How we work at Vertice Engineering 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 without traditional tech leads or managers. 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. * Chapters - Specialists still need to stay aligned. Chapters bring together people with similar expertise - like Frontend, Test Automation or Release - to share best practices, standards, common sense and they keep the knowledge flowing across teams - directly!
