Job description

Vertice was launched in 2022 to build a new way to manage SaaS and cloud spend. One that’s fair, totally transparent, and designed for modern businesses. Today, Vertice has processed over $10 billion in spend and serves hundreds of customers across more than 30 countries. We are headquartered in London with offices across the world including New York, Brno, Sydney, Johannesburg and Singapore.

And we’re just getting started. Founded by successful serial entrepreneurs Roy Tuvey and Eldar Tuvey, Vertice is on an incredible growth trajectory. We’ve seen a remarkable 13X revenue growth in two years, resulting in us being named as 2025’s fastest-growing startup in the UK by the FT’s Sifted, and as fourth in Europe. Following our Series C investment round, we have secured over $100 million in funding from leading investors including Bessemer Venture Partners, 83North and Lakestar, and are expanding our reach across regions and product lines.

Are you ambitious? Do you want to make an impact and be part of a highly talented and driven team? Come and join us on this journey to build a new way to manage technology spend and simplify procurement.

Your Role

As a Solutions Architect at Vertice, you’ll play a pivotal role in designing and implementing solutions across the Vertice platform — with a strong focus on Intelligent Workflows (IW). You’ll work hands‑on with customers to design architectures, build integrations, and configure workflows that drive automation and efficiency across procurement, finance, and vendor management. This is a customer‑facing, technically hands‑on role for someone who enjoys solving complex integration challenges and translating business needs into scalable technical solutions. You’ll collaborate closely with customers, Customer Success, Product, and Engineering teams to ensure smooth and impactful deployments.

Responsibilities

• Lead onboarding and solution design for new customers, focusing on procurement and workflow automation use cases.
• Own the end‑to‑end technical implementation across Vertice products — including configuration, integration, and testing.
• Design and implement API‑based integrations between Vertice and customer systems (ERP, CLM, ITSM, TPRM, etc.).
• Read and interpret API documentation to define data flows, mappings, and authentication methods (OAuth2, API keys, SSO).
• Be hands‑on in building, testing, and deploying integrations using tools like Postman, Workato, n8n, or similar.
• Work with Product and Engineering to validate feasibility, debug integration issues, and shape roadmap priorities.
• Conduct customer workshops, training, and enablement sessions to ensure strong adoption.
• Manage multiple implementation projects in parallel, maintaining high quality and clear communication.
• Act as the primary technical contact for configuration, customization, and integration‑related queries.
• Provide feedback to internal teams to improve deployment frameworks and overall customer experience.

Requirements

• 6+ years of experience in Solutions Architecture, Technical Consulting, or Implementation within SaaS or enterprise software.
• Strong hands‑on experience with REST APIs, including reading documentation, building payloads, and handling authentication flows.
• Proven ability to design, configure, and deploy API‑based integration workflows between enterprise systems.
• Skilled in data formats (JSON, XML, CSV) and comfortable using API tools (Postman, Swagger, cURL).
• Excellent project management, communication, and stakeholder management skills.
• A proactive problem solver who enjoys owning technical challenges and making customers successful.

Nice to Have

• Experience with procurement, finance, or IT tools like NetSuite, Coupa, Ironclad, Workday, OneTrust, or SAP Ariba.
• Experience with workflow automation or iPaaS tools such as Workato, n8n, MuleSoft, or Zapier.
• Basic scripting ability (Python, JavaScript) for light data manipulation or workflow automation.
• Experience designing scalable integration frameworks in high‑growth SaaS environments.
