Plant Engineer

Penn Life Sciences is seeking an experienced Plant Engineer to join our team in Langhorne, PA.

The Plant Engineer will serve as a hands-on, field-oriented engineer responsible for improving the reliability, performance, capacity, and compliant operation of manufacturing equipment, building systems, and supporting plant infrastructure within a sterile pharmaceutical manufacturing facility. This role will investigate recurring technical problems, implement sustainable engineering solutions, improve process performance and yields, eliminate equipment and operational constraints, and execute engineering and site-improvement projects. The ideal candidate will demonstrate strong hands-on troubleshooting capabilities, full proficiency in AutoCAD and P&IDs, and the ability to translate field observations and performance data into practical, measurable improvements.


This position’s responsibilities will include, but not be limited to the following:

  • Conduct hands-on field investigations, equipment inspections, technical measurements, testing, and troubleshooting to identify and resolve recurring equipment, facility, and operational problems.
  • Determine the root causes of equipment failures, process-related defects, downtime, and performance losses, and implement sustainable corrective and reliability improvements.
  • Improve plant performance and manufacturing yields by reducing process variability, defects, scrap, rework, recurring failures, and other operational losses.
  • Identify and eliminate manufacturing and packaging constraints involving line stoppages, cycle times, material flow, equipment capacity, layouts, utilities, and supporting infrastructure.
  • Develop engineering designs, equipment and facility layouts, specifications, P&IDs, schematics, redlines, and as-built drawings using AutoCAD, including field verification of existing conditions.
  • Execute engineering and site-improvement projects from field assessment and scope development through design, vendor coordination, installation, testing, startup, commissioning, qualification support, and operational turnover.
  • Support change controls, deviations, CAPAs, risk assessments, and other cGMP documentation while coordinating technical activities with Manufacturing, Maintenance, Quality, Validation, and other site functions.

We are looking for applicants with:

  • Bachelor’s degree in Mechanical Engineering, Chemical Engineering, Electrical Engineering, Manufacturing Engineering, Industrial Engineering, or a related engineering discipline required; Mechanical Engineering preferred.
  • Minimum of 3 years of relevant plant, manufacturing, process, facilities, or reliability engineering experience, preferably within a pharmaceutical, biotechnology, medical device, or other regulated manufacturing environment.
  • Experience supporting sterile, aseptic, or other cGMP-regulated pharmaceutical manufacturing operations strongly preferred.
  • Demonstrated hands-on experience troubleshooting equipment and plant systems and supporting equipment modifications, installation, testing, startup, or commissioning activities.
  • Full proficiency in AutoCAD and in reading, creating, revising, and field-verifying P&IDs, equipment layouts, utility drawings, schematics, redlines, and as-built documentation.
  • Demonstrated experience improving equipment reliability, process performance, manufacturing yields, product quality, production capacity, or operational efficiency.
  • Ability to execute engineering projects while maintaining accurate technical documentation and complying with change-control procedures, cGMP requirements, engineering standards, and site safety requirements.

What we offer:

  • 401(k) with company match
  • Health, vision, and dental Insurance
  • Childcare expense reimbursement
  • Tuition reimbursement
  • Annual bonus eligibility
  • Annual merit increases
  • Paid Time Off and Flexible Holidays
