Senior Mechanical Design Engineer

Re:Build Manufacturing • Rochester, NY

3d • Onsite

About The Position

Re:Build Optimation is seeking an experienced Senior Mechanical Design Engineer to own the engineering of custom process equipment and remain hands-on with design and modeling. The role designs skid-based, modular, and containerized systems in 2D and 3D, supports designs with calculations and analysis, and advances projects from concept to validated, buildable design. Relevant backgrounds may include process equipment, pressure vessels and heat exchangers, industrial machinery, or engineering services. The engineer is expected to make sound engineering decisions, balance performance with manufacturability and cost, and consult specialists when appropriate.

The position works directly with clients to clarify their needs and translate input into documented project requirements and a design basis. It is based onsite in Rochester and/or Rush, New York, with occasional travel to customer and supplier locations, typically less than 25%.

Re:Build Optimation provides custom-engineered process equipment and automated systems, with capabilities spanning concept, fabrication, installation, and commissioning. Its work serves industries including traditional and green energy, chemicals, pharmaceuticals, food and beverage, glass, and advanced manufacturing.

Requirements

• Bachelor of Science in Mechanical Engineering or a related engineering field.
• At least 7 years of mechanical design engineering experience in process equipment, industrial systems, or engineering services.
• Advanced proficiency with 3D and 2D modeling software, including SolidWorks and working knowledge of AutoCAD, or similar tools.
• Strong experience with engineering calculations, equipment sizing and selection, and design analysis using SolidWorks Simulation, ANSYS, or similar tools.
• Working knowledge of applicable codes and standards, such as ASME Section VIII and ASME B31.3.
• Ability to independently manage complex design assignments from concept through detailed design and release.
• Experience reviewing technical drawings, solving design challenges, and collaborating with engineering and manufacturing teams.
• Strong communication, organization, and problem-solving skills, including the ability to provide technical guidance to other designers.
• Associate degree, bachelor's degree, technical certification, or equivalent professional experience in Mechanical Design, Drafting, Engineering Technology, or a related field.
• Commitment to safety, quality, and continuous improvement.
• Ability to work onsite in Rochester and/or Rush, New York, and travel occasionally, up to 25%.

Nice To Haves

• Professional Engineer (PE) license, or Engineer in Training (EIT) status with a plan to pursue licensure.
• Experience designing skid-mounted or modular process systems, pressure vessels, or heat exchangers.
• Familiarity with engineering analysis and simulation tools such as SolidWorks FEA, ANSYS, or Caesar II.
• Experience with AutoCAD Plant 3D and 3D point clouds.
• Experience developing technical estimates, supporting proposals, or participating in customer design reviews.
• Experience mentoring junior engineers and designers or leading technical design activities.
• Knowledge of industrial safety standards and equipment design requirements.

Responsibilities

• Lead mechanical design of industrial process systems, particularly skid-based and modular equipment, from requirements through release, commissioning support, and handoff.
• Model and manage SolidWorks parts, assemblies, weldments, and sheet metal, as well as AutoCAD 2D/3D layouts.
• Develop general arrangements, equipment layouts, fabrication and assembly drawings, and bills of material.
• Define technical requirements, design bases, and specifications with clients and the project team.
• Perform engineering calculations and select and size equipment such as pumps, heat exchangers, vessels, tanks, valves, and drives.
• Run simulation and analysis, including FEA, structural, thermal, and pipe stress analysis, and ensure designs meet ASME B31.3, ASME Section VIII, and client requirements.
• Lead technical design reviews, evaluate design solutions, and provide guidance to project teams and customers.
• Partner with fabrication and assembly teams to resolve technical challenges and support equipment builds and installations.
• Support project planning, technical proposals, and engineering estimates.
• Mentor junior designers and engineers, provide technical guidance, and review design and engineering work.
• Improve engineering and design standards, tools, and processes to enhance quality, consistency, and efficiency.

Benefits

• Medical, dental, and vision benefits.
• Retirement benefits.
• Paid time off.
• Other benefits as part of a comprehensive benefits package.
• Employees share ownership in the company and participate in financial rewards from its success.
