Ingénieur Mise en Service / Ingénieur Senior Mise en Service (H/F)

Job Description

The Commissioning Engineer / Senior Commissioning Engineer is responsible for leading and executing the end-to-end commissioning of Smart Wires' Static Synchronous Series Compensator (SSSC) SmartValve systems and associated control infrastructure at high-voltage transmission substations across Europe and, as required, globally.

This is the primary engineering role within the Technical Services team responsible for project delivery within the EU. The role requires a technically strong, customer-facing engineer who is comfortable working independently at high-voltage substation sites, managing complex multi-stakeholder environments, and maintaining Smart Wires' reputation for technical excellence and delivery quality.

The role is home-based within Europe with approximately 50% of time spent on-site at customer substations, and the remainder working remotely from home providing engineering support, documentation, and technical assistance to projects globally.

Key Responsibilities

Project Delivery & Commissioning

• Lead the planning, coordination, and execution of secondary systems Factory Acceptance Tests (FAT) and all Site Acceptance Tests (SAT) for SmartValve deployments.
• Produce, maintain and review commissioning schedules, Inspection and Test Plans (ITPs/ITRs), and safety documentation.
• Design and review control system integration for project-specific deployments.
• Lead SCADA design, configuration, and customer-witnessed SCADA testing.
• Execute on-site commissioning activities, including pre-installation inspections, SAT, offline and online commissioning.
• Provide customer training
• Manage commissioning spares, as-built documentation, and site configuration backups.
• Manage Field Issues throughout project delivery and ensure timely closeout.
• Support the Project Manager with project closeout activities.

Technical Services & Support

• Provide structured remote support to field staff and customers.
• Contribute to the development and maintenance of standard designs, SCADA templates, HMI configurations, and ITPs/ITRs.
• Author and review Technical Services processes and deployment documentation.
• Assist with the development and delivery of customer operator training.
• Provide technical assistance to the Commercial team for pre-tender activities and site visits.
• Support firmware update activities, including preparation of customer-specific update documentation.

Post-Commissioning & Failure Analysis

• Obtain and review site telemetry and Event Data Recorder (EDR) data following commissioning.
• Develop and maintain troubleshooting protocols and ITP/ITRs for failure investigation and remedial works.

Remedial & Warranty Works

• Plan and coordinate warranty works, including spares management and site logistics.
• Lead or assist with on-site inspections, testing, and re-commissioning activities.

Requirements

Education

• Bachelor's degree, Master's degree, Dipl.-Ing., or equivalent in Electrical Engineering or a closely related discipline.

Experience

• Minimum 3 years of experience as a Commissioning Engineer working on high-voltage transmission, distribution, or renewable connection substations.
• Demonstrated experience in the design or testing of substation control systems, HMIs, and SCADA.
• Familiarity with communication protocols including IEC 61850 Client/Server, IEC 60870-5-101/104, and/or DNP3.
• Experience with primary plant commissioning and/or protection relay testing is an advantage.
• Experience commissioning or supporting FACTS devices is an advantage.

Skills & Competencies

• Strong technical problem-solving and fault-finding capability in complex multi-vendor environments.
• Effective communication skills with both technical and non-technical stakeholders, including utility customers.
• Ability to work independently and manage own workload across concurrent projects.
• Comfortable working at heights and in energised high-voltage substation environments.
• Proficiency with standard network engineering tools including PuTTY, Wireshark, and network diagnostic utilities.
• Proficiency in vendor tools for configuring protection relays / control system IEDs
• Competent in Microsoft Office suite.

Language

• Fluent English is essential (working language of the team and customer documentation).
• Proficiency in one or more European languages is an advantage.

Work Conditions

This is a site and home-based role within Europe. The successful candidate will be the primary commissioning resource for all EU projects, with the expectation of up to 50% of time spent on-site at customer substations across Europe. Travel beyond Europe - including to the UK, USA, Latin America, and Asia Pacific - may be required periodically to provide hands-on or remote commissioning support to global projects.

The role requires compliance with all applicable site safety regulations, including the use of Personal Protective Equipment (PPE), adherence to high-voltage safety protocols, and compliance with customer site access requirements.

Exposure to high-voltage hazards and the requirement to work at height should be expected as part of normal site activities.
