Collaborate closely with Last Energy's engineering, project development, and legal teams to ensure deal structures are technically and operationally feasible

Identify and escalate technical risks or misalignments early in the deal process to protect project timelines

Contribute to proposal development, RFP responses, and customer-facing technical documentation
