Role Overview

Ensurge is seeking a Head of Equipment & Facilities Engineering to own the availability, reliability, and scalability of manufacturing equipment and facility infrastructure. This is a player-coach role spanning equipment engineering, maintenance, and facilities, responsible for keeping tools running today while designing systems that will scale tomorrow. Reporting to the COO, this leader partners tightly with Manufacturing Engineering and Technology to ensure equipment and infrastructure are fit-for-purpose, maintainable, and production-ready at every roadmap milestone.

This role directly impacts uptime, yield, safety, and delivery, and requires someone who can troubleshoot, coach engineers and technicians, and set the long-term technical direction. As Ensurge transitions from technology development into disciplined pilot manufacturing and scale, equipment reliability and facility robustness become mission-critical differentiators.

Key Responsibilities

• Equipment Engineering & Reliability:
• Own equipment performance across pilot and production lines, uptime, availability, MTBF, and MTTR.
• Act as escalation point for complex tool issues - hands-on when needed.
• Define equipment standards, maintenance strategies, and spare parts philosophy.
• Lead equipment qualification, acceptance, and process handoff in partnership with Manufacturing Engineering.
• Drive root cause analysis and corrective actions for chronic equipment issues.
• Maintenance Strategy & Execution:
• Build and lead a disciplined preventive and predictive maintenance program.
• Establish clear ownership between engineering and maintenance without silos.
• Develop technician capability through training, documentation, and coaching.
• Implement CMMS discipline and data-driven maintenance prioritization.
• Balance firefighting with long-term reliability improvements.
• Facilities & Infrastructure:
• Own critical facility systems, utilities, vacuum, gases, HVAC, cleanroom, safety systems.
• Ensure facilities support current processes and future scale requirements.
• Partner with landlords, contractors, and vendors on upgrades and expansions.
• Lead site readiness for audits, safety reviews, and regulatory compliance.
• Proactively identify infrastructure risks that could limit throughput or yield.
• Cross-Functional Integration:
• Partner with Manufacturing Engineering on tool-process matching and readiness.
• Support Technology R&D during early tool development and process experimentation.
• Enable Operations with stable, well-documented equipment and escalation paths.
• Align Quality, EHS, and Facilities requirements into daily execution.
• Scaling & Capital Readiness:
• Build the equipment and facilities roadmap aligned to product and capacity plans.
• Support CapEx planning, vendor selection, FATSAT, and installation.
• Ensure lessons learned from pilot tools feed into next-generation designs.
• Prepare Ensurge for future site expansions or transitions with minimal disruption.
• Leadership & Team Development:
• Player-coach lead mentor and develop equipment engineers, facilities engineers, and technicians.
• Set expectations for rigor, urgency, and ownership.
• Establish clear roles on-call structures and escalation models.
• Model hands-on leadership - present at the gemba when it matters most.

What Were Looking For

Were seeking a proven leader with experience in equipment and facilities engineering in advanced manufacturing environments, semiconductor, battery, thin-film electronics, or similar. Were looking for someone with a strong hands-on background with complex manufacturing equipment and infrastructure, experience building reliability and maintenance systems from immature or reactive states, and comfort operating as both a technical expert and people leader.

Were also looking for someone who can prioritize under pressure without losing sight of long-term system health, is located in or willing to regularly work on-site in the San Jose area, and has the following preferred qualifications:

• Experience supporting pilot fabs or first-of-kind manufacturing lines.
• Familiarity with vacuum systems, deposition tools, roll-to-roll equipment, or cleanroom operations.
• Experience scaling facilities and infrastructure in constrained or leased environments.
• Background implementing CMMS, spare parts strategies, and reliability KPIs.
• BSMS in Engineering or equivalent practical experience.

Personal Attributes

Were looking for someone with a player-coach mentality - leads from the front and builds others up. Were looking for someone who is calm under pressure, decisive in ambiguity, and has a deep sense of ownership - treats uptime and safety as personal responsibilities. Were looking for someone who is collaborative, low-ego, and trusted across functions, and a disciplined problem solver with a bias toward action and learning.
