Job description

About the Role

We are looking for an Infrastructure Lead to own the day-to-day health, performance, and evolution of a customer's network and systems estate under along-term managed services contract. You will be the senior technical authority on the account — leading a team of engineers through incidents, problems, and changes, acting as the customer's trusted technical point of contact, and turning operational insight into architecture recommendations that support their modernisation roadmap.

This is a customer-facing delivery leadership role, not a back-office engineering role. You will pair hands-on technical depth with the confidence to run service reviews, manage escalations, and represent our technical credibility to customer IT leadership.

Lead the team

• Lead, mentor, and performance-manage a team of L1–L3 network and/or systems engineers, including 24x7 or on-call rostering where the account requires it.

• Lead operational service reviews and contribute technical content to QuarterlyBusiness Reviews.

Keep it compliant and improving

• Ensure changes and configurations stay compliant with customer security policy, contractual obligations, and regulatory requirements; maintain accurate CMDBand asset records and support audits.
• Automate repetitive work — provisioning, config backup, health checks, patching.
• ChampionAI-assisted monitoring and observability (anomaly detection, predictive alerting, noise reduction) to shift the account from reactive to proactive operations.

What You'll Bring

• 8–15years of hands-on network, systems/infrastructure, or combined infrastructure engineering experience in managed services, outsourced IT, or large enterpriseIT operations.
• At least 2–3 years as a team lead, senior/principal engineer, or technical escalation lead with responsibility for other engineers.
• Proven ownership of production infrastructure under SLA, with fluency in ITIL-aligned incident, problem, and change management.
• Direct experience working with an end-user customer in a managed services model, including running operational service reviews.
