Senior Engineer, HV Engineering

The Company

Cypress Creek Energy is powering a sustainable future, one project at a time. We develop, finance, own and operate utility‑scale and distributed solar and storage projects across the country. Fostering a diverse group of innovative thinkers from all backgrounds, Cypress people are drawn to work in a purpose‑driven organization. We hope you will join us.

CCE is seeking a Senior Engineer, HV Engineering to serve as a lead technical authority on generation and load interconnection engineering, substation design, and utility compliance. This role sits at the intersection of substation design and project execution. You'll provide hands‑on technical guidance that shapes how CCE designs, builds, and commissions utility‑scale solar, storage, and co‑located large load facilities across our national portfolio.

This is an individual contributor and cross‑functional role reporting to the Senior Manager of HV Engineering.

Interconnection Engineering, Engineering Management, & Technical Support

• Provide technical engineering support for interconnection requests on both generation and load projects, including initial queue submissions, material modifications, and as‑built updates.
• Review internal site plans and single line diagrams (SLDs) for physical interconnection feasibility and utility compliance, including Point of Interconnection (POI) substation expansion configurations.
• Review ISO/RTO interconnection studies including System Impact Studies (SIS), Facilities Studies, and short circuit studies to validate assumptions, identify cost drivers, and flag technical concerns on behalf of CCE project teams.
• Review and validate consultant‑prepared generator and load models across all interconnection lifecycle stages — initial requests, as‑built submissions, and material modifications — in PJM, MISO, ERCOT, WECC, and other markets.
• Manage external engineering consultants and technical parties to create deliverables and studies necessary for project execution.

• Support EPC procurement processes including preparation and review of RFPs for substation and interconnection scope.
• Respond to EPC technical RFI’s, ensuring alignment with overall project design, company standards and value engineering.
• Review EPC‑submitted design packages and engineering studies for technical accuracy, utility compliance, and alignment with internal company standards. This includes reviewing substation and project level electrical, P&C, and physical designs.

• Develop and review Owner‑Furnished Equipment (OFE) datasheets and technical specifications to ensure compliance with utility standards and project requirements. OFE typically includes substation main power transformers and HV circuit breakers.
• Review of OEM equipment drawings and factory test reports for major substation equipment across CCE's project portfolio.

• Lead technical interconnection oversight with utilities and transmission owners throughout the project lifecycle, serving as CCE's primary engineering point of contact on HV and utility engineering matters.
• Provide high voltage and utility engineering support during construction, commissioning, and energization activities. This includes coordinating with utility on project back‑feed and providing guidance to internal PM’s on testing and commissioning activities.

• 5+ years of power systems or transmission engineering experience in a utility, generation developer, EPC, or consulting engineering environment.
• Working knowledge of utility substation design, HV equipment specifications, and interconnection study processes across multiple ISOs/RTOs and utilities.
• Preference for candidates with steady‑state and dynamic modeling tools (PSS/E, Power World, ETAP, or equivalent) as well as experience reviewing wide area screening analyses.
• Experience reviewing substation design (electrical/P&C) packages and commissioning documentation.
• Strong organizational skills with the ability to manage and prioritize across multiple simultaneous work streams.
• Excellent written and…
