About The Position

LS Power is seeking an Engineering Manager, Mechanical (Process) to join System Integration Engineering as a part of our San Diego, CA-based team. Remote candidates will be considered, with the expectation of periodic travel to the San Diego office for in-person collaboration. This role is responsible for overseeing the integration and engineering of mechanical and thermal process systems for projects that include gas-fired, carbon capture, sequestration and storage (CCS), flexible co-located, and renewable energy facilities. These projects may also be connected to digital infrastructure like hyperscale data centers, and the position covers all stages from conceptual design through to development and execution. The role will provide technical support to project development teams for thermal generation systems, CO₂ compression and pipeline transport, electrical interconnection, and multi-technology integration. Along with systems integration engineering activities, additional responsibilities include technology selection, site evaluation, conceptual design, planning, scheduling, cost estimating, due diligence, status reporting, and overseeing external vendors and contractors, such as original equipment manufacturers (OEMs) engineering and consulting firms.

• Experience supporting mechanical systems for hyperscale data center or digital infrastructure projects
• Familiarity with design and performance modeling

Responsibilities

• OEM, Vendor & Consultant Interface
• Interface directly with OEMs and equipment vendors to evaluate technological options, technical parameters, scope of supply, performance guarantees, operational flexibility, O&M philosophies and future upgrade pathways
• Establish OEM and BOP equipment technical and commercial overview for project development options
• Review and provide technical oversight of process and mechanical engineering deliverables prepared by external consultants ensuring consistency with system integration objectives
• Lead definition of process and mechanical scope for owner’s engineering studies
• Provide inputs to plant cost estimates, plant schedules, and installation assessments from engineering and project development perspectiv
• Process & Mechanical System Integration
• Serve as the process and mechanical systems lead within the System Integration Engineering team
• Evaluate, integrate, and develop system configurations for power generation, including gas turbine cycles, combined cycles, heat recovery processes, and mechanical balance-of-plant, onsite fuel supply integration
• Develop overall process configurations, operating modes, and design concepts, including hybrid and flexible operating scenarios such as combined cycle plus storage or peaking assets paired with digital infrastructure
• Perform system-level process and mechanical analyses to support feasibility studies, concept selection, and development decision gates
• Develop and review heat and mass balances, process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), performance assumptions, emissions controls, and equipment sizing inputs
• Assesses impacts of process design decisions on efficiency, operability, reliability, maintainability, cost, and schedule, and develop mitigation strategies early in the project lifecycle
• Support process and mechanical–electrical system integration at a conceptual level, including auxiliary power requirements and system interfaces
• Contribute to development of mechanical design standards, assumptions, and tools to support repeatable project development
• Support process and mechanical-electrical system integration, instrumentation and controls, instrumentation layouts and coordinate with Electrical Engineering to ensure alignment of process assumptions and electrical system impacts including auxiliary loads, startup sequences, control interfaces, and system boundaries
• Project Development Milestones
• Support technical documentation for investment approvals, due diligence, permitting interfaces, and transition to EPC execution
• Understand, track, and support project development engineering milestones
• Lead process and mechanical engineering handoff to the Project Delivery team, ensuring process design intent, key assumptions and constraints, identified risks and mitigations, performance and operability criteria
• Provide early execution support as projects transition into EPC delivery

Benefits

• We provide our team the opportunity to share their unique perspectives, solve new challenges, and continue in their career growth.
• We are committed to supporting employees’ happiness, healthiness, and overall well-being by providing comprehensive benefits that include 100% employer paid premium healthcare, paid parental leave and more.
