What You’ll Be Doing

• Managing delivery across integration and batch-heavy workstreams
• Driving stakeholder engagement across engineering, architecture and business teams
• Coordinating inter-team dependencies and unblocking issues
• Tracking delivery, risks and issues using Jira
• Supporting investigation into legacy applications, historic data usage and batch processes
• Helping shape the transition from mainframe to cloud-based platforms (e.g. AWS microservices / SAAS)

What We’re Looking For

• Proven experience as a Delivery Manager in complex, legacy or transformation environments
• Strong stakeholder management and communication skills
• Comfortable working across multiple teams and domains
• A technical enough background to understand the landscape and challenge constructively (not language-specific)
• A deep-dive mindset for investigating historic issues and dependencies
• A hands-on performer, not a purely coaching delivery lead

Programme Context

• Several applications identified for decommissioning (mainly housekeeping)
• Several applications already decommissioned but with data still in use
• Other systems at varying stages (awaiting strategic decisions, re-implementation, or unknown)
• The mainframe currently limits speed of change and AI adoption

Contract Details

• Initial 6 months contract with extensions likely focused on discovery and shaping
• Inside IR35
• £500 per day - via Umbrella
• Start required within 6 weeks
• On-site workshops as required in London and occasionally Coventry (typically 1-2 days per week, flexible otherwise)
