Mechanical Engineer Temporary information

What does a temporary mechanical engineer do?

A temporary mechanical engineer is hired for a specific period or project to assist with designing, developing, testing, or maintaining mechanical systems. Their duties are similar to those of permanent mechanical engineers, but their employment is limited to a certain duration, often to meet increased workload or specialized project needs. Temporary mechanical engineers may work on tasks such as drafting technical drawings, performing calculations, conducting tests, and supporting production teams. This role provides flexibility for both the employer and the engineer, making it ideal for project-based work.

What does a temporary mechanical engineer do?

As a temporary mechanical engineer, your job is to support a company for the duration of your assignment, which is usually until a specific project is completed. In this role, you may help plan the construction of a building, determine the industrial needs of the project, help obtain any materials the blueprint design requires, provide design recommendations, and maintain the equipment used throughout the project. You may use a handheld device to scan or check materials. Temporary mechanical engineers work on projects of various sizes; you may install single pieces of delicate equipment in an existing building, or plan the removal and reinstallation of walls, ceilings, or support structures.

What are the typical projects and responsibilities for a mechanical engineer in a temporary position?

Mechanical Engineers in temporary roles are often brought in to support specific projects, such as product design updates, testing, or process improvements. You may be tasked with conducting technical analyses, creating CAD models, or assisting with prototype development under tight deadlines. Collaboration is common, as you'll frequently work with cross-functional teams like manufacturing, quality assurance, and project management to ensure project milestones are met. This fast-paced environment can provide valuable exposure to diverse challenges and industries, making it a great opportunity to build skills and expand your professional network.

What are the key skills and qualifications needed to thrive as a temporary mechanical engineer, and why are they important?

To thrive as a Mechanical Engineer Temporary, you need a solid understanding of mechanical design principles, engineering mathematics, and a relevant engineering degree, often supported by EIT or PE credentials. Proficiency in CAD software (such as SolidWorks or AutoCAD), simulation tools, and project management systems is typically required. Strong problem-solving abilities, adaptability, and effective teamwork make candidates stand out in this role. These skills and qualities are crucial for delivering timely, innovative engineering solutions and integrating seamlessly into project-based teams.

What is the difference between Mechanical Engineer Temporary vs Mechanical Engineer Permanent?

AspectMechanical Engineer TemporaryMechanical Engineer Permanent
CredentialsTypically requires a bachelor's degree in mechanical engineering; certifications are optionalSame as temporary; often preferred to have professional engineer (PE) license
Work EnvironmentProject-based, short-term assignments, often in manufacturing, automotive, or aerospaceLong-term employment, involved in ongoing design, development, and maintenance projects
Employer & Industry UsageUsed by staffing agencies and companies for short-term needsEmployed directly by companies for continuous roles
Search & Comparison IntentCommonly compared for contract vs full-time rolesOften contrasted with temporary roles for career stability

In summary, a Mechanical Engineer Temporary typically works on short-term projects through staffing agencies, requiring similar credentials as permanent roles but offering less job stability. Permanent Mechanical Engineers have ongoing employment with benefits and career growth opportunities, making them suitable for those seeking long-term stability.

Under the direction of the Engineering & Estimating Manager -National, the Mechanical Engineer is responsible for supporting the Engineering and Estimating team across the full project lifecycle, including load calculations, system design, bidding support, client presentations, field deployment, and post-project documentation. This is an engineering-track role with exposure to a wide variety of industries and applications. The day-to-day work is office-based, with travel for site visits, client meetings, and emergency response.

Essential Job Functions:

  • Perform load calculations - cooling, heating, moisture, and ventilation - for temporary climate solutions across construction sites, industrial and manufacturing facilities, food production plants, automotive and battery plants, aerospace facilities, data centers, commercial buildings, and labs
  • Perform psychrometric chart analyses and study weather to inform design decisions
  • Design temporary systems from Polygon's equipment fleet
  • Develop project layouts, equipment schedules, and sequences of operation tailored to each client's environment and process needs
  • Support the estimating process: take-offs, equipment selection, scope development, and pricing inputs for bids and proposals
  • Prepare and present engineered solutions to clients, general contractors, and internal sales teams
  • Translate technical decisions into clear, client-friendly language
  • Serve as the engineering resource for the field technician team during equipment deployment, startup, commissioning, and troubleshooting
  • Travel to project sites on short notice when needed - for emergency response, project kickoffs, complex deployments, or field issues that require engineering oversight
  • Translate field observations into improvements to design and project execution
  • Develop and maintain Standard Operating Procedures (SOPs) for specific systems, applications, and key clients
  • Create technical documentation, including system narratives, commissioning checklists, monitoring plans, and project closeout packages
  • Build out engineering templates and reference materials to improve consistency and efficiency across the team

Job Qualifications:

  • Bachelor's degree in Mechanical Engineering or a related field
  • Solid understanding of thermodynamics, heat transfer, and HVAC fundamentals
  • Comfortable with psychrometric calculations
  • Strong written and verbal communication skills, with the ability to explain technical concepts to engineers, salespeople, technicians, and clients
  • MS Office proficiency across the board, with Excel as a particular strength
  • Demonstrated CAD experience
  • Willingness to travel on short notice, including occasional nights and weekends for emergency response
  • Valid US driver's license and the ability to work on construction and industrial job sites

Preferred Training Requirements and Competencies:

  • EIT certification
  • 1-3 years of experience in HVAC, mechanical contracting, temporary climate solutions, dehumidification, or a related field
  • Exposure to construction sites, manufacturing facilities, food production, automotive or battery plants, aerospace, data centers, or controlled environments such as labs, cleanrooms, and pharmaceutical facilities
  • Familiarity with building codes, OSHA site safety, and standard PPE requirements
  • Experience supporting estimating, sales, or field service teams

Demonstration of the Polygon Values:

  • Integrity
  • Excellence
  • Empathy
