We provide our global teams with the resources and opportunities to achieve their career goals while advancing science and developing solutions to some of the world’s toughest challenges-from protecting the environment and ensuring food safety to supporting the development of life-saving therapies.

The Role

Join our collaborative R&D team as a Product Development Engineer III, where you will lead the design, development, and optimization of mechanical products and processes for fluid-handling and pressurized equipment.

This role combines hands-on mechanical engineering, product development, manufacturing expertise, and project leadership. You will work closely with cross-functional partners across R&D, Manufacturing, Quality, Regulatory, Supply Chain, Sales, and Marketing to develop innovative, reliable, and cost-effective solutions from initial concept through commercialization.

You will apply your technical expertise to solve complex engineering challenges, improve existing products, and develop next-generation solutions while ensuring designs meet applicable quality, safety, and regulatory requirements.

What You’ll Do

  • Lead mechanical design and product development activities for fluid-process and pressurized equipment, including pressure vessels, piping, valves, pumps, and related systems.
  • Develop engineering concepts and translate them into robust, manufacturable, and cost-effective designs.
  • Perform technical analysis and design optimization to improve product performance, reliability, quality, and manufacturability.
  • Support projects throughout the full product development lifecycle, from concept and design through testing, validation, industrialization, and commercialization.
  • Lead and coordinate cross-functional project activities to deliver agreed technical, schedule, cost, and quality objectives.
  • Partner with Manufacturing to optimize fabrication and assembly processes, including metal forming/drawing, casting, welding, polishing, precision machining, mechanical assembly, and testing.
  • Ensure designs comply with applicable codes, standards, regulatory requirements, and customer expectations for pressurized and fluid-process equipment.
  • Coordinate and supervise subcontracted engineering activities, including external design and calculation work.
  • Investigate complex technical issues, identify root causes, and implement practical engineering solutions.
  • Apply Lean, Six Sigma, Agile, or other continuous-improvement methodologies where appropriate.
  • Serve as a technical resource for internal teams, suppliers, and customers.
  • Support supplier and customer visits as required, with travel of up to approximately 15%.

Education & Experience

Required:

  • Master’s degree in Mechanical Engineering with 5+ years of relevant industry experience, or
  • Bachelor’s degree in Mechanical Engineering with 7+ years of relevant industry experience.
  • Demonstrated mechanical engineering experience with fluid-process equipment such as pressure vessels, piping, valves, pumps, or similar equipment.
  • Experience working within a manufacturing environment.
  • Experience managing or leading engineering projects involving industrial or engineered products.

Technical Knowledge & Skills

  • Strong mechanical design expertise related to pressurized equipment and fluid-process systems.
  • Working knowledge of relevant engineering codes, standards, and regulatory requirements for metal pressure vessels and fluid-process equipment, including applicable ASTM standards.
  • Understanding of regulatory and industry requirements across markets such as pharmaceutical, biotechnology, food, oil and gas, automotive, coatings/paint, nuclear, and military/defense industries, as applicable.
  • Strong understanding of manufacturing processes used for metal pressure vessels and related equipment, including forming/drawing, casting, welding, polishing, machining, assembly, and testing.
  • Manufacturing experience involving metal fabrication, precision machining, mechanical assembly, and product testing.
  • Experience with design and process optimization methodologies such as Lean, Six Sigma, or Agile.
  • Understanding of how functions such as R&D, Manufacturing, Quality, Regulatory, Supply Chain, Sales, and Marketing collaborate throughout the product lifecycle.

Key Capabilities

The successful candidate will demonstrate:

  • Ability to independently develop engineering concepts and cost-effective designs.
  • Strong technical analysis and complex problem-solving skills.
  • Ability to evaluate complex situations and recommend practical, technically sound solutions.
  • Strong project management skills with the ability to lead cross-functional teams toward defined outcomes.
  • Excellent organization, planning, and time-management skills, with the ability to manage multiple priorities and meet commitments.
  • Strong written and verbal communication skills, including the ability to communicate technical concepts effectively to different audiences.
  • Ability to coordinate external engineering partners, vendors, and subcontractors.
  • Strong internal and external customer orientation.
  • Commitment to continuous improvement and the ability to apply Lean principles where relevant.
  • Ability to work effectively both independently and collaboratively in a cross-functional environment.

Travel

Up to 15% travel may be required for supplier, vendor, and customer visits.

What Success Looks Like

You will be a key technical contributor and project leader who can take complex mechanical engineering challenges from concept to practical implementation. You’ll combine strong knowledge of pressurized and fluid-process equipment with manufacturing expertise, cross-functional collaboration, and disciplined project execution to deliver safe, reliable, compliant, and commercially successful products.
