Mechanical Design Engineer

Lead Mechanical Design Engineer – Industrial Chemical Processing Systems

Location: Norfolk, MA |
Work Type: Hybrid (office + remote flexibility)

Employment Type: Full Time

Are you a seasoned Process or Mechanical Design Engineer looking for a highly technical, hands‑on role where your engineering expertise directly shapes complex, real‑world systems? This opportunity places you at the center of designing sophisticated chemical handling and processing systems—supporting projects across industries that rely on precision, safety, and high‑performance engineering.

You’ll join a long‑established engineering organization with 40+ years of experience delivering turnkey industrial systems involving acids, caustics, corrosive materials, hazardous fume capture, and advanced chemical processing technologies. If you enjoy transforming concepts into fully engineered systems, collaborating with clients, and taking ownership of complete design packages, this role offers both challenge and long‑term stability.

• Process Flow Diagrams (PFDs) with mass balances
• Piping & Instrumentation Diagrams (P&IDs)
• General Arrangement layouts, equipment layouts, and detailed fabrication drawings
• Translate client scope into system concepts, layouts, and production‑ready designs
• Create and maintain accurate technical drawings and models using AutoCAD (2D/3D)
• Develop and manage Bills of Materials (BOMs) for costing and system build‑out
• Work directly with vendors to finalize specifications for equipment, piping, instrumentation, and system components
• Maintain Materials of Construction (MOC) standards and ensure compliance with codes, regulations, and safety requirements
• Develop Operator Manuals (OMs) and design documentation

• Manage engineering tasks independently while coordinating closely with internal teams, clients, and vendors
• Solve design challenges creatively with strong engineering judgment
• Support field‑installation needs and system start‑up activities (occasional U.S. travel)

• B.S. in Mechanical Engineering, Chemical Engineering, or closely related field
• 5+ years of Mechanical Design or Process Engineering experience
• Advanced proficiency with AutoCAD (2D & 3D)
• Strong understanding of fluid systems, pumps, valves, heat exchangers, corrosion‑resistant materials
  , and industrial equipment
• Ability to interpret programming logic diagrams and electrical/wiring diagrams
• Excellent communication skills and ability to collaborate with engineers, clients, and vendors
• Strong organizational habits—documentation, archiving, BOM management, and version control
• Ability to work independently and manage your own engineering workload
• Must be a U.S. Citizen due to client site and data‑access requirements

• SIMPLE IRA Plan
• Paid Time Off (PTO)
• Hybrid work flexibility
• Long‑term career stability in a niche, highly technical engineering field

This is an opportunity to become a key contributor in a specialized engineering environment where your designs directly influence safety, environmental performance, and operational reliability for major industrial clients. You’ll work hands‑on with complex systems, collaborate with highly skilled engineers, and contribute to projects that carry real impact—while enjoying the flexibility and close‑knit culture of a smaller engineering team.
