Project Manager (Temp - 3 months)

Description

Enphase is developing a next-generation Solid-State Transformer (SST) platform for grid-scale energy conversion. We need a highly organized Project Manager Temp for 3 months to coordinate engineering, supply chain, test, and operations teams during a critical 3-month execution window with aggressive demo milestones. This role requires you to be onsite in our Austin, TX location.

What You WIll Do

• Drive day-to-day coordination across hardware, firmware, power electronics, mechanical, test, and supply chain teams to meet SST deliverable milestones.
• Coordinate engineering teams to build prototype SST products.
• Build and maintain an integrated project schedule with clear milestones, dependencies, owners, and critical path.
• Track procurement, long-lead items, and vendor deliveries; escalate supply chain risks before they become blockers.
• Coordinate engineering change orders (ECOs) and configuration control through Arena PLM.
• Manage build schedules for prototype and demo units — material kitting, lab scheduling, and build readiness.
• Support vendor coordination including PO tracking, delivery follow-up, and on-site supplier support.

Who you Are and What you Bring

• Exceptional cross-functional coordination — ability to align 5+ engineering disciplines and keep parallel workstreams on track.
• Strong project scheduling with dependency management and critical path analysis.
• Proven accountability and follow-through in fast-paced, ambiguous environments.
• Clear, concise communication to both engineering teams and executive leadership.
• Proficiency with project management tools (MS Project, Smartsheet, Jira, or equivalent).
• Experience coordinating procurement, vendor management, and supply chain logistics.
• Comfortable working on-site in a lab/prototype environment alongside engineers.
• Background in power electronics, energy storage, inverters, or transformer products.
• Experience with NPI (New Product Introduction) in a hardware-intensive environment.
• Bachelor's degree in Engineering, Project Management, or related technical discipline.
• 5+ years of project/program management in hardware product development.
• Experience managing cross-functional engineering teams in a matrix organization.
• Track record of delivering complex technical projects on schedule.

What Success Looks Like (3-Month Outcomes)

• Integrated program schedule established within first 2 weeks, adopted by all workstreams.
• Weekly cross-functional reviews running with clear action tracking.
• Demo milestones delivered on time with no coordination-related delays.
• Supply chain risks identified early and mitigated before impact.
• Leadership has clear visibility into program status at all times.

The range for this position is $48 - $70/hr and may vary based on experience, skills, and location.
