ABOUT THE ROLE

As our first Principal Solutions Engineer at Talon.One in EMEA, you will be leading enterprise-level API integrations. This newly created role focuses exclusively on delivering these complex integrations, which often span over a year due to their complexity. You will lead the charge on these initiatives, collaborating closely with cross-functional teams while acting as a trusted advisor to ensure customer success. While you won't have direct reports, you'll be in a unique position to mentor and share your expertise with the US & EMEA Technical Account Management (TAM) team, shaping both technical and project management best practices. This is a rare opportunity to make a significant impact, allowing you the freedom to define the role while driving excellence in integrations.

This role also requires occasional travel, estimated at 10%-20% of the time.

ONCE YOU ARE HERE YOU WILL

• Serve as a trusted advisor to enterprise customers, offering tailored solutions and long-term architectural strategies
• Lead the design, development, and implementation of large-scale API integrations, ensuring alignment with customer goals, platform capabilities, and industry best practices
• Collaborate with implementation partners and system integrators (SIs) to ensure solution architectures are technically sound and in the customer’s best interest
• Drive project planning for enterprise-level integrations, including scope definition, resource allocation, timeline management, and stakeholder coordination
• Analyze, troubleshoot, and optimize API integrations, ensuring performance, scalability, and long-term maintainability post-launch, using tools like Postman, Swagger, and API gateways
• Evaluate integration outcomes and partner performance, delivering actionable insights for internal teams and future engagement strategies
• Mentor Technical Account Managers on API architecture, integration tooling, and project execution, enhancing team-wide technical depth

WHAT WE NEED YOU TO BRING TO THE TABLE

• 5+ years in a technical consulting, solutions architecture, or developer/contractor role, ideally with direct experience integrating API-driven SaaS platforms for enterprise clients
• Familiarity with API technologies and tools such as REST, SOAP, OAuth, JSON/XML, Postman, Swagger (OpenAPI), and middleware platforms like Workato, Mulesoft, or Zapier
• Proven ability to lead complex technical projects, managing multiple stakeholders, risks, and deliverables in a structured, detail-oriented way
• Strong architectural understanding of modern cloud platforms (AWS, Azure, or GCP) and scalable SaaS systems
• Experience with Commerce Stacks, Consumer Data Platforms, and Consumer Engagement Platforms is a big plus
• Experience in Retail, CPG, Travel, Telco, or Delivery Services is beneficial
• Excellent communication skills, with the ability to explain complex technical topics clearly to both technical and non-technical audiences
• A collaborative, mentor-first mindset, with a passion for growing team capability and improving processes based on real-world integration challenges

WHAT'S IN IT FOR YOU

• £850 annual learning budget and full LinkedIn Learning access
• 30 days of annual leave, plus extra paid days for your birthday and moving day
• £250 home office setup budget, a £40 monthly home office allowance
• Freedom to work from abroad for up to 90 days worldwide!
• WeWork On-Demand access for flexible workspace solutions
• Group Medical Insurance with BUPA for you and your dependents
