Senior Manager - DevOps

Role Overview

The Portal DevOps Lead is a hands-on technical leadership role responsible for supporting the delivery, reliability, and operational readiness of portal services. The role combines practical engineering across cloud platforms, identity and authentication services, CI/CD tooling, Linux, and networking with leadership responsibilities including backlog refinement, user story creation, work prioritisation, delivery management, release management, and production support handover to BAU teams.

Key Responsibilities

• Act in partnership with the Portal Team Owner to help define strategy, future growth and best of breed service.
• Lead backlog refinement activities, ensuring work items are clearly defined, prioritised, and ready for delivery.
• Create, shape, and refine user stories, acceptance criteria, technical tasks, and delivery dependencies.
• Prioritise engineering work in collaboration with product owners, delivery managers, architects, security teams, and operational stakeholders.
• Provide hands-on DevOps engineering support across AWS services, CI/CD pipelines, Linux environments, networking, and identity and authentication components.
• Manage delivery plans, track progress, identify risks and blockers, and support predictable delivery against agreed milestones.
• Own and coordinate release management activities, including release planning, environment readiness, deployment coordination, rollback planning, and stakeholder communication.
• Ensure production support handover to BAU teams is complete, including operational documentation, support processes, monitoring expectations, known issues, and escalation paths.
• Support incident investigation, problem management, and service improvement activities where DevOps expertise is required.
• Promote automation, repeatability, security, resilience, and operational excellence across the portal platform.
• Provide technical guidance, mentoring, and leadership to engineers while remaining actively involved in implementation and troubleshooting.

Required Technical Skills

• Strong knowledge of identity management concepts, access control, authentication, authorisation, and secure user lifecycle management.
• Experience with authentication flows and federation standards, including SAML and OIDC.
• Hands-on experience with AWS services, including EC2, EKS, CloudFront, RDS, and AWS Transfer Family.
• Experience building, maintaining, and troubleshooting CI/CD pipelines using GitLab.
• Strong Linux administration, shell usage, troubleshooting, and operational support skills.
• Good understanding of networking fundamentals, including DNS, routing, firewalls, load balancing, certificates, TLS, and connectivity troubleshooting.
• Experience supporting cloud-hosted production services, including monitoring, alerting, incident response, and operational readiness.
• Ability to translate technical requirements into deliverable engineering tasks and support implementation through to release.
  

Leadership and Delivery Expectations

• Act as the technical delivery lead for portal DevOps workstreams, balancing hands-on contribution with coordination and leadership.
• Drive clarity across scope, dependencies, acceptance criteria, sequencing, and release readiness.
• Communicate effectively with technical and non-technical stakeholders, providing clear updates on progress, risks, issues, and decisions required.
• Support team planning ceremonies and ensure work is broken down into achievable, well-understood deliverables.
• Champion production readiness, secure delivery practices, documentation quality, and effective transition into BAU support.
• Lead by example through practical engineering contribution, pragmatic decision-making, and a focus on reliable service outcomes.

Experience and Background

The successful candidate will typically have significant experience in DevOps, cloud engineering, platform engineering, or site reliability engineering, with demonstrable experience delivering and supporting production-grade services. They should be comfortable working across engineering, product, security, infrastructure, and BAU operational teams, and should be able to move confidently between strategic planning, delivery coordination, and hands-on technical problem solving.

Key Success Measures

• Backlog items are clear, prioritised, and ready for delivery.
• User stories and technical tasks are well-defined with appropriate acceptance criteria.
• Releases are planned, communicated, delivered, and supported effectively.
• Production support handovers are complete, practical, and accepted by BAU teams.
