  • Support end-to-end SDLC from requirements through production deployment
  • Review code, mentor junior developers, and promote best practices
  • Work directly with UK public sector clients, participating in technical discussions and workshops
  • Stay current with MuleSoft, Salesforce, and integration technology updates, including the use of AI to improve development efficiency

Essential Skills & Experience

  • Strong hands-on experience as a Senior MuleSoft Developer
  • Expertise in MuleSoft Anypoint Platform, Mule 4, and API-led architecture
  • Solid integration design and development experience
  • Experience delivering solutions across the full SDLC
  • Strong client communication skills, with UK client exposure
  • Ability to work flexibly across different projects and client environments
  • Eligible for SC Clearance (or already SC-cleared)

Desirable Experience

  • MuleSoft certifications (Developer or Architect)
  • Experience with Salesforce integrations
  • Exposure to AI-driven development, automation, or productivity tooling
  • Consulting or multi-client delivery experience
