Client : Public Sector Location : Hybrid, London or Birmingham, 2 days per week onsite Engagement Type : Contract (Outside IR35) Day Rate : Up to £500 per day, depending on experience Clearance : Active SC Clearance required. Should be immediately available to start the new role About the role A public sector client needs a Senior Boomi Architect to set the technical direction for a high-profile integration programme. This is the person who owns how integrations get designed across the estate, then stays close enough to the build to keep those standards real. You'll define the architecture and the reusable patterns the wider team delivers against. You'll also stay hands-on where it counts: shaping the complex integrations, unblocking the team, and making the calls that keep business-critical services running. It's a hybrid role. You'll be onsite at either the London or Birmingham office 2 days a week, with the site confirmed during the process. Key responsibilities Own the integration architecture on the Boomi AtomSphere platform, across Cloud Integration, Application Integration, and API Management. Design solutions end to end: model the requirements, choose the patterns, and document decisions clearly enough that others can build from them. Set the technical standards, reusable assets, and governance the development team works to, and improve them as the programme grows. Mentor Boomi developers and review their work to raise the quality bar across the team. Run the stakeholder conversations that matter: probe for the real requirement, build consensus where people disagree, and turn fuzzy ideas into something deliverable. Manage expectations on milestones, dependencies, and timelines, and flag risk early. Essential experience 8+ years in integration, with deep hands-on Boomi experience and time spent in an architecture or technical lead role. A track record of designing Boomi integration solutions end to end, including one or more of Salesforce, NetSuite, or Oracle EBS. Strong command of SOAP, REST, XML, JSON, and JavaScript / Groovy scripting. Experience defining standards and reusable frameworks that other developers build on. A pragmatic problem-solver who can explain technical trade-offs to technical and non-technical people alike. Nice to have Boomi certification (Professional Developer or Architect level). Prior public sector or regulated-environment delivery. Security clearance You'll need active SC Clearance to be considered.
