As a Senior Staff Commissioning Engineer on the Spark team, you will own commissioning for these modules. That covers factory testing in Brighton, site integration, integrated systems testing, and formal turnover to operations. Spark moves much of commissioning into the factory. You will build the test standards, procedures, and quality gates that let every module ship ready to energize and come online quickly at the site. You will be the technical authority for mechanical and controls commissioning across the Spark fleet, and you will turn lessons from each deployment into improvements in module design, manufacturing, and the commissioning program itself. This is a full-time role.

What You'll Be Working On

- Commissioning Program Ownership: Own the Spark commissioning program end to end. Define how L1–L5 activities split between the factory and the site, and build standardized Cx plans, test scripts, and turnover packages that scale across a fleet of modules. - Factory Testing: Lead factory acceptance and integration testing of mechanical, cooling, and controls systems at the Brighton factory so every module meets specification before it ships. - Quality Gates: Set first-article inspection, in-process quality checks, and ship-readiness criteria with manufacturing and quality teams. Hold shipment when a module does not meet them. - Site Integration and IST: Oversee installation validation, startup, and integrated systems testing at deployment sites. Verify that modules connect correctly to site power, cooling, and network infrastructure. - Design and Manufacturing Feedback: Track commissioning issues across builds, identify root causes, and drive fixes into module design, supplier quality, and factory processes. - Vendor and CxA Management: Manage third-party commissioning agents and equipment suppliers, including scope, schedule, deliverables, and factory witness testing of purchased components. - Technical Escalation: Serve as the primary escalation point for mechanical and controls issues in the factory and in the field, from troubleshooting through formal closure. - Cross-Functional Leadership: Align engineering, manufacturing, construction, controls, and operations teams on commissioning scope, roles, and readiness milestones. - Operations Handover: Deliver complete, accurate turnover documentation. Support the transition to operations through training coordination and post-handover support. - Safety and Compliance: Enforce safety, compliance, and regulatory requirements across factory and site commissioning activities.
