What does a mechanical system engineer do?

A Mechanical System Engineer designs, develops, and oversees the installation and maintenance of complex mechanical systems in various industries. Their work often involves integrating mechanical components with electrical and software systems to ensure the overall functionality and efficiency of machines or equipment. They may be responsible for tasks such as performing simulations, analyzing system performance, troubleshooting issues, and collaborating with multidisciplinary teams. Mechanical System Engineers play a critical role in industries like automotive, aerospace, manufacturing, and energy. Their expertise ensures that mechanical systems operate safely, reliably, and efficiently.

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

To thrive as a Mechanical System Engineer, you need a solid background in mechanical engineering principles, system design, and problem-solving, typically supported by a bachelor's degree in mechanical engineering or a related field. Familiarity with CAD software (such as SolidWorks or AutoCAD), simulation tools, and industry certifications like PE (Professional Engineer) are often required. Strong analytical thinking, teamwork, and effective communication skills help distinguish top performers in this role. These skills ensure efficient design, implementation, and maintenance of complex mechanical systems, leading to reliable project outcomes and innovation.

What are some common challenges mechanical system engineers face when working on multidisciplinary projects?

Mechanical System Engineers often collaborate closely with electrical, software, and civil engineers on multidisciplinary projects. A common challenge is ensuring effective communication between teams, as each discipline may use different technical language and have varying priorities. Managing integration issues and aligning timelines across departments can also be demanding. To overcome these challenges, Mechanical System Engineers typically participate in regular cross-functional meetings and use collaborative project management tools to ensure alignment and successful project delivery.

What is the difference between Mechanical System Engineer vs Mechanical Design Engineer?

AspectMechanical System EngineerMechanical Design Engineer
Primary FocusDeveloping and integrating mechanical systems within larger projectsCreating detailed mechanical component and product designs
Work EnvironmentSystems integration, testing, and validation in manufacturing or engineering firmsDesign studios, CAD modeling, and prototype development
Required CredentialsBachelor's in Mechanical Engineering, relevant certificationsBachelor's in Mechanical Engineering, CAD certifications

Mechanical System Engineers focus on integrating and managing entire mechanical systems, while Mechanical Design Engineers concentrate on designing specific components. Both roles often collaborate but serve different stages of product development and system integration.

Job description

 Pioneering Carbon Conversion and Renewable Energy Systems

Location: Franklin, TN (On-Site)
Type: Full-Time
Experience Level: Mid to Senior

Join Enexor BioEnergy

Located just outside Nashville, TN, Enexor is a fast-moving early-stage climate tech company building small-scale, waste-to-value systems that convert organic and plastic waste into renewable energy and high-purity CO. We're not just innovating-we're disrupting the status quo.

Why Join Us?

  • Mission-first impact: Help turn waste and emissions into energy and carbon-negative value streams.
  • Handson innovation: Engineers here don't just design-they build, test, iterate, and deploy real systems.
  • People over process: We move fast, cut red tape, and trust smart, driven individuals to take ownership.
  • High-value team: We hire the best; we challenge each other; we win together.

If you're ready to move beyond the drawing board and make real-world impact, come help shape the future of distributed energy and carbon conversion systems.

The Role

We're hiring Senior Mechanical Engineers and a Mechanical Engineering Manager to support the design, development, and deployment of our next-generation waste-to-energy system and our post-combustion carbon capture system. These roles will focus on subsystem design, cross-functional integration, and end-to-end ownership of mechanical program execution.

These positions are ideal for senior-level engineers and technical leaders who thrive in a fast-paced, hardware-driven environment. You'll be involved from initial concept and design through fabrication, testing, and deployment.

Key Responsibilities
  • Design, model, and test mechanical subsystems for gas separation, thermal systems, and pressure environments.
  • Integrate capture modules with upstream flue gas sources and downstream conditioning units.
  • Own full mechanical lifecycle from concept through CAD, DFM, BOM, sourcing, and assembly.
  • Use tools like INVENTOR, ANSYS, ASPEN, and MATLAB to optimize design performance.
  • Lead testing and validation: build rigs, instrument systems, collect data, and iterate fast.
  • Collaborate with process, controls, and fabrication teams to ensure seamless system integration.
  • Support design-to-cost strategy and scaling for manufacturability.

Requirements

Required Qualifications
  • B.S. or M.S. in Mechanical Engineering or related discipline.
  • 3-10 years of mechanical design and systems integration experience.
  • Strong proficiency in 3D CAD (Autodesk Inventor preferred) with working knowledge of FEA and CFD.
  • Demonstrated ability to take systems from concept to prototype to deployment.
  • Hands-on experience with piping, pressure systems, structural frames, or heat exchangers.
  • Solid analytical and first-principles problem-solving skills.
Preferred Experience
  • Experience working with swing adsorption systems (e.g., PSA, VSA, or similar gas separation technologies).
  • Background in flue gas treatment, gas purification, or emissions control systems.
  • Familiarity with containerized or modular systems for field deployment.
  • Experience in techno-economic analysis or cost-driven design.
  • Certifications such as P.E., PMP, or MBA are beneficial but not required.

Benefits

Compensation & Benefits
  • Equity opportunity in a fast-scaling, venture-backed climate tech company.
  • Competitive salary based on experience and impact.
  • Health insurance stipend (QSEHRA) and 401(k) plan.
  • Paid vacation and holidays.

To Apply:
Send your resume and a brief note to careers@enexor.com. Highlight your experience with swing adsorption or mechanical system development in clean energy or gas separation.
