About Optimal

Optimal is a growing property maintenance and refurbishment business, delivering responsive and planned works for clients including estate agents, housing associations, commercial clients and private landlords. We combine strong operational delivery with responsive customer service. We're building our own system with AI and automations to reduce routine administration, improve visibility and give our team more time to focus on relationships, commercial decisions and results.

About The Role

Your role is to build, manage and continually improve Optimal's network of engineers, suppliers and subcontractors. You'll proactively bring new businesses into our supply chain, negotiate competitive prices and terms, and ensure they consistently meet our standards for quality, reliability, communication and service. This is a hands‑on, commercially focused role. Success means having the right trades, materials and capacity available where we need them, at the right cost, with partners who deliver on their commitments. Your responsibility continues beyond onboarding. You'll track performance, address problems, develop strong partners and replace those who consistently fall short. You'll work closely with Operations, Client Project Managers and Finance to ensure our supply chain supports profitable growth.

• Agree corrective actions with owners and deadlines, then verify that improvements happen
• Coordinate remedial work with Operations and escalation serious or repeated failures
• Recommend restricting, suspending or replacing partners who do not meet our standards, within agreed processes and authority

Build strong working relationships

• Act as the main relationship owner for suppliers and subcontractors, working alongside the teams coordinating individual jobs
• Build professional relationships that support dependable service, fair commercial terms and long‑term cooperation

• Resolve recurring concerns around instructions, access, materials, approvals or invoice queries with the relevant internal teams

• Escalate safety concerns, missing documentation and material risks promptly through the appropriate channels

Use AI And Improve How We Work

• Check AI-generated information before using it for commercial or operational decisions
• Help develop our own system and automations by identifying repetitive tasks and gaps in supply chain visibility
• Create and improve practical processes for sourcing, onboarding, performance reviews and renewals
• Use data to identify weak coverage, recurring failures and opportunities to improve cost and service
