Role Purpose

The Senior Platform Engineer is responsible for designing, building, automating, operating and continuously improving the shared engineering platforms used by delivery teams across Momentum Corporate.

The role focuses on platform implementation and platform operations, ensuring that engineers can consume secure, reliable and self-service platform capabilities without requiring manual intervention from central teams. The Senior Platform Engineer works within the architectural direction established by the Senior Platform Engineering Lead and is responsible for translating platform architecture into working platform products and services.

The role combines platform engineering, cloud engineering, DevOps, SRE and automation skills.

Requirements

• Bachelor's degree or equivalent in Computer Science, Information Systems, Engineering or related discipline.
• 10+ years experience across software engineering, cloud engineering or platform engineering.
• 3+ years experience in a senior platform engineer role.
• Experience building and operating enterprise-scale cloud platforms.
• Experience defining platform standards and engineering guardrails

Duties & Responsibilities

Platform Engineering and Automation

• Design, build, configure and operate secure, reliable and reusable engineering platform capabilities.
• Translate approved platform architecture and engineering standards into working platform products, automation and self-service
• services.
• Automate infrastructure provisioning, configuration, deployment and operational activities using Infrastructure as Code and GitOps practices.
• Develop reusable templates, modules and platform components that reduce duplication across engineering teams.

Developer Platform and Experience

• Build and maintain developer self-service capabilities, engineering templates, service catalogue integrations and golden paths.
• Enable engineering teams to provision environments and deploy applications with minimal dependence on central teams.
• Work directly with engineering teams to identify delivery friction and continuously improve the developer experience.
• Maintain clear technical documentation and usage guidance for platform capabilities.

CI/CD and Software Delivery

• Build and maintain standardised CI/CD pipelines and deployment automation.
• Embed automated testing, security scanning, quality controls and policy enforcement into engineering workflows.
• Support safe deployment patterns, environment promotion, rollback and recovery.
• Improve the repeatability, speed and reliability of software delivery.

Cloud and Runtime Platforms

• Engineer and operate cloud, container and Kubernetes platform capabilities.
• Implement secure cloud foundations, networking, identity, access and environment configurations in line with approved architecture.
• Monitor platform capacity, performance, availability and cost, and implement improvements where

  required.

• Maintain platform components through upgrades, patching and lifecycle management.

Reliability, Observability and Security

• Build observability into platform capabilities using standard logging, metrics, tracing, dashboards andalerts.
• Define and implement platform service-level indicators and operational health measures.
• Participate in incident response, root-cause analysis and the engineering of permanent corrective actions.
• Embed security controls, secrets management, access controls and compliance guardrails into the platform by default.
• Reduce recurring operational work through automation and engineering.

Technical Leadership and Collaboration

• Provide technical guidance and mentoring to platform engineers and delivery teams.
• Contribute to platform design decisions, technical reviews, engineering standards and the platform

  roadmap.

• Collaborate with Architecture, Software Engineering, Security and Production Management to ensure

  platform capabilities are usable, supportable and aligned with organisational standards.

• Evaluate new platform technologies through practical prototyping and evidence-based recommendations.

Competencies

Success will be measured through:

• Increased adoption of standard platform capabilities, reusable components and golden paths.
• Reduced time to provision environments, onboard engineers and establish new application services.
• Increased percentage of infrastructure, configuration and deployments managed through code and automation.
• Reduced manual platform requests, engineering toil and duplicated platform solutions.
• Improved deployment frequency, lead time for change, deployment success and recovery time.
• Achievement of agreed platform availability, performance, security and service-level objectives.
• Improved observability coverage and reduced recurrence of platform-related incidents.
• Positive feedback from engineering teams on platform usability, reliability and developer experience.
• Platform changes delivered in line with agreed engineering standards, security controls and operational readiness requirements.
