About The Position

In this Development Engineering role, you will support all design and development engineering activities across our storage only and storage + portfolio. This role is critical in shaping how our storage solutions are designed, developed, deployed, and scaled. You will own the engineering process from early-stage feasibility through 30% design, including technical support for major equipment procurement and construction contracting. This is a hands-on, build-from-scratch role ideal for someone excited to take ownership in a startup environment, develop infrastructure and process, and help shape the way future projects get designed and built.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, Energy Systems, or a related field.
• Sr. Dev Engineer: 4+ years of engineering experience in the energy sector, with a minimum of 2 years designing utility scale or commercial scale BESS and PV projects.
• Experience working at a project developer/owner operator or an understanding of the project owner mindset.
• Demonstrated ability to support cross-functional efforts and deliver results under tight timelines.
• General familiarity with interconnection processes and ISO/RTO requirements.
• Proficiency with design and modeling tools such as AutoCAD, PVsyst, PVFarm or equivalent.
• Excellent written and verbal communication skills; ability to translate complex technical concepts to diverse stakeholders.

Nice To Haves

Responsibilities

• Support the development of technical roadmaps for BESS and PV+S projects.
• Develop technology standards and design templates for repeatable project deployment.
• Lead system design and architecture including battery, PV module selection and racking selection.
• Develop site constraints and generate creative layouts to help better characterize site conditions and risks.
• Work cross-functionally with project development, finance, and legal to evaluate project feasibility and optionality using site constraints and knowledge about technology options.
• Help manage Owner’s Engineers and other technical consultants (scope, schedule, budget) in generating site studies to advance projects through development to handover to EPC.
• Provide technical due diligence on potential sites and project acquisitions.
• Support engineering deliverables for interconnection studies, grid compliance, and permitting packages.
• Support bid preparation, RFP responses, and technical presentations to offtaker and financing counterparties.
• Partner with procurement and EPCs to define scopes, review designs, and resolve design/field issues.
• Actively manage the early stage design process with EPCs and OEs to ensure alignment and clear handoffs to EPCs and other counterparties.
