Senior Integration Engineer

Senior Integration Engineer, Workato

London, hybrid | 3-month contract, starting late November | Up to £640/day inside IR35

A well-known global consumer brand is hiring a contract Integration Engineer to build its shared Workato platform from the ground up.

The business is moving away from point-to-point integrations to one platform that every delivery team can build on. A managed service partner will run it day to day, so this is a build role, not a support one. You’ll work alongside the integration architect who sets the standards, turn those standards into a working platform, and hand it over in a state that doesn’t need you.

What you’ll do

• Build the core Workato platform: recipes, custom connectors, reusable recipe functions, API Platform, environment management and error handling.
• Set up CI/CD for Workato, with automated testing, version control and controlled deployment across environments.
• Create the templates, patterns and guardrails that let domain teams build their own integrations without waiting on a central team.
• Build in security from the start, with OAuth 2.0, mTLS and access control.
• Help shape how AI agents connect to business systems through the integration layer.
• Write the runbooks and documentation, then hand everything over to permanent engineers through pairing and walkthroughs.

What they’re looking for

• Around 6 to 8 years in integration, middleware or platform engineering on complex, multi-system estates.
• Hands-on Workato experience, including custom connectors and reusable recipe functions, ideally with Workato certifications.
• At least one other iPaaS, such as MuleSoft, Boomi or Informatica, and an API management platform such as Apigee, Azure API Management or Kong.
• CI/CD and Infrastructure as Code (Terraform or Bicep) for integration deployment.
• Event-driven experience with Kafka or Azure Service Bus.
• A track record of enabling other teams and handing platforms over cleanly to permanent staff.

Contract details

• Up to £640 per day, inside IR35 via umbrella
• 3-month initial contract, starting late November
• Hybrid from a London office, 4 days on site and 1 from home

This is a rare chance to build an enterprise integration platform from scratch and shape how other teams build on it after you’ve gone. The start date is close and the process will move quickly. Apply below or get in touch directly.
