Solar Engineering Lead – Preliminary Design

Role Overview

• Develop and review preliminary PV layouts prepared by Project Engineers, providing clear, actionable feedback to ensure technical accuracy and completeness.
• Ensure all preliminary designs align with the Scope of Work, owner requirements, and internal standards, proactively identifying deviations, risks, and missing inputs.
• Align DC collection strategies and key design decisions with Engineering Services electrical guidance and applicable codes and standards.
• Integrate lessons learned into preliminary design practices to drive continuous improvement and elevate overall design quality.
• Own the timely delivery of complete preliminary design packages, ensuring clean, well-documented handoffs to downstream teams with clearly stated assumptions and decisions.
• Accurately estimate effort and timelines for preliminary design tasks, prioritizing review cycles to support Project Engineer productivity and meet RFP and pipeline deadlines.
• Coordinate cross-functionally to resolve interface conflicts, close open technical items, and maintain alignment across disciplines.
• Maintain an organized version control and change tracking, clearly identifying the current approved design set.
• Make cost-conscious design decisions that reduce commercial risk and support efficient field execution.
• Minimize rework and downstream change orders through early risk identification, scope clarity, and resolution of ambiguities before handoff.
• Escalate potential safety risks in designs or deliverables and adhere to all Moss and Engineering Services safety protocols.
• Mentor and coach team members on preliminary design standards, workflows, and quality expectations, providing timely and constructive feedback.
• Communicate design decisions, trade-offs, and technical rationale clearly to foster strong cross-disciplinary collaboration.
• Identify resourcing or capability gaps early and propose practical solutions, supporting onboarding and skill development in preliminary design processes.
• Contribute to the refinement of workflows, checklists, and templates to improve efficiency, consistency, and overall handoff quality.

Requirements

• Bachelor's degree in engineering, technical field, or related discipline
• required.
• 3+ years of project engineering and preliminary design engineering experience in the Utility-Scale Solar industry
• required.
• Utility-scale Battery Energy Storage System (BESS) experience
• preferred.
• Proficient knowledge of electrical systems, layouts, civil considerations, and AC and DC collection strategies.
• Understands sequencing and hand-offs from estimating preliminary design and downstream partners.
• Recognizes risks early and escalates scope/alignment issues for resolution.
• General budget awareness understands how Preliminary Design scope, materials, and assumptions affect cost and field execution.
• Proficiency in Excel and design/drafting tools for site constraints and layout trade-offs.
• Strong analysis and problem-solving for option evaluation and early conflict resolution.
• Effective written/verbal communication across disciplines and partners.
