- Apply project delivery standards, stage gates, acceptance criteria and quality controls, and recommend improvements where appropriate.
- Identify, assess and manage technical risks for assigned customer deployments, escalating where appropriate.
- Ensure high‑quality engineering documentation, including as‑built configurations, network diagrams, security controls, test reports and operating procedures.
- Ensure delivery practices reflect relevant safety, cybersecurity, grid compliance, utility IT/OT and data privacy requirements.
- Service and reliability partnership
- Work closely with Service Operations to ensure smooth operational handover and clear runbooks.
- Provide advanced engineering support for complex technical issues beyond standard support playbooks.
- Support major upgrades, system enhancements and advanced troubleshooting when required.
