Senior Manager, Additive Fleet

About the role

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Senior Manager, Additive Fleet is responsible for the day‑to‑day performance of Hyliion's laser powder bed fusion (LPBF) printer fleet in Austin, which produces the complex, high‑density metal heat exchanger hardware in the KARNO Core. This hardware can only be produced through metal additive manufacturing, so Hyliion's ability to build KARNO at scale depends directly on the health, uptime, and throughput of the fleet. The role leads the technicians and operators who run and maintain the machines, owns the preventive maintenance strategy, machine‑health monitoring, and decisions on hardware and software upgrades. The fleet runs the full range of Colibrium Additive LPBF platforms, including new machine technology being adopted in real time, with a primary focus on reducing machine‑to‑machine variation and building repeatable processes across machine models. This is a hands‑on leadership role with regular time on the shop floor, and its scope will grow as Hyliion's print capacity scales.

Responsibilities

• Own fleet uptime and drive continuous improvement in machine‑to‑machine consistency across Hyliion's LPBF printer fleet.
• Build and maintain a preventive maintenance program across all machines to identify failure modes before they cause downtime.
• Lead, schedule, and develop the team of technicians and operators who run and maintain the fleet.
• Develop machine‑health monitoring using machine data and sensor feeds to predict failures, plan maintenance, and inform fleet‑wide decisions.
• Evaluate and make decisions on hardware and software upgrades as new capability becomes available from Colibrium Additive and other sources.
• Lead fleet expansion planning as print capacity scales, including layout, staffing, and process readiness for new machines.
• Build repeatable processes across different machine models and maintain high uptime as new platforms come online.
• Own the learning curve on new machine technology and platforms, and build institutional knowledge as Hyliion adopts next‑generation LPBF systems.
• Walk the shop floor regularly to identify process improvement opportunities and drive changes that reduce variation and maximize uptime.
• Troubleshoot and resolve issues that threaten fleet uptime, including outside of normal working hours when needed.
• Additional duties and responsibilities as assigned, needed, or required for the business.

Qualifications

• Bachelor's degree in engineering or a related field, with a focus on advanced manufacturing.
• 5+ years of hands‑on experience with LPBF (laser powder bed fusion) additive manufacturing in a production environment.
• Experience with Colibrium Additive (formerly GE Additive) machines strongly preferred.
• Experience leading a team, either in a formal management role or as a lead technical contributor.

Skills and Abilities

• Hands‑on skill running and troubleshooting LPBF machines at the operator and technician level.
• Track record of driving process improvement on production additive manufacturing equipment.
• Thorough understanding of machine optical calibration and its impact on part quality and machine‑to‑machine consistency.
• Ability to analyze machine data and sensor/log data to make fleet‑level decisions on maintenance, upgrades, and process changes.
• Understanding of the physics underlying LPBF machine operation, sufficient to predict performance and diagnose root causes of variation.
• Ability to evaluate and adopt new machine hardware and software as it becomes available.
• Self‑starter who identifies problems proactively and works hands‑on at the machine level.
• Ability to lead and develop a team of technicians, even without an extensive formal management background.
• Comfort working through uncertainty of new machine technology and building processes and playbooks as the technology matures.
• Willingness to work extended or off‑hours as needed to maximize fleet uptime.

Working Conditions

• Salaried, exempt‑level position.
• Typical work environment: production/assembly/engineering lab.

Physical Requirements
