Salary: £60,000 - £65,000 + £6,000 Car Allowance

The Opportunity:

This is an exciting opportunity for someone who enjoys combining hands‑on technical delivery with solution architecture and technical leadership. You'll act as the technical authority across Professional Services and Field Engineering, taking ownership of complex projects from initial discovery and design through to implementation, testing and final handover.

What You'll Be Doing:

Technical Leadership & Solution Architecture

• Take ownership of technical direction across Professional Services and Field Engineering projects.
• Lead client discovery sessions, gather requirements and translate business needs into effective technical solutions.
• Design and deliver complex infrastructure, cloud, networking, security and modern workplace solutions.
• Develop technical designs, statements of work, implementation plans, bills of materials and risk assessments.
• Establish and maintain technical standards, best practices, reference architectures and security controls.
• Review proposed solutions to ensure they are secure, scalable, resilient, commercially viable and fit for purpose.

Hands-On Technical Delivery

• Lead and personally deliver complex IT infrastructure projects and technical implementations.
• Get hands‑on with installations, upgrades, migrations, configurations, testing and system improvements.
• Take ownership of technical deliverables from project kick‑off through to successful completion.
• Work across multiple client projects, ensuring delivery remains on track, within scope and to a high technical standard.
• Identify and resolve technical challenges, manage risks and ensure successful project go‑lives.
• Ensure all solutions are properly tested, documented and handed over to operational support teams.

Engineering Leadership & Mentoring

• Act as the senior technical escalation point for complex issues and challenging projects.
• Provide technical guidance, coaching and knowledge sharing to engineers across the business.
• Lead technical reviews, peer reviews and engineering discussions to continually improve delivery standards.
• Carry out root‑cause analysis and implement long‑term solutions to recurring technical problems.
• Work closely with Project Managers to coordinate technical resources, project estimates and delivery milestones.

Client Relationships & Project Delivery

• Build strong relationships with clients, acting as their senior technical point of contact throughout project delivery.
• Explain technical solutions, recommendations, risks and challenges to both technical and non‑technical stakeholders.
• Ensure projects are delivered in line with agreed requirements, timescales and expectations.
• Produce and review technical documentation, including high‑level and low‑level designs, configuration records, test results and as‑built documentation.
• Ensure a smooth transition from project delivery into ongoing operational support.

You’ll ideally bring:

• Significant experience designing and delivering complex IT infrastructure, cloud or managed service solutions.
• Strong technical knowledge across Microsoft 365, Azure, identity and access management, endpoint management, virtualisation, networking, backup and disaster recovery.
• Experience delivering infrastructure migrations, cloud transformations, technical deployments and complex implementations.
• Strong solution design and technical architecture capabilities.
• Excellent troubleshooting and problem‑solving skills, with the ability to manage complex technical escalations.
• A solid understanding of cybersecurity, security‑by‑design, resilience and infrastructure best practices.
• Experience with project scoping, technical estimations, resource planning and delivery management.
• The ability to provide technical leadership and support to other engineers without necessarily having direct line‑management responsibility.
• Excellent communication skills and confidence working directly with clients and senior stakeholders.
• Strong documentation skills and an appreciation of the importance of quality, governance and operational handover.
