What is a senior gas engineer?

Senior Gas Engineers are highly experienced professionals responsible for installing, maintaining, and repairing gas systems and appliances in residential, commercial, or industrial settings. They ensure that all gas works comply with safety regulations and industry standards. In addition to hands-on technical work, they often supervise junior engineers, oversee complex projects, and provide expert advice on gas-related issues. Their role requires strong problem-solving skills, in-depth knowledge of gas safety, and the ability to interpret technical drawings and documentation.

What are the key skills and qualifications needed to thrive as a senior gas engineer?

To thrive as a Senior Gas Engineer, you need in-depth knowledge of gas systems, strong problem-solving abilities, and relevant qualifications such as a degree in engineering and Gas Safe registration. Familiarity with technical tools like CAD software, gas detection equipment, and safety compliance systems is typically required. Leadership, effective communication, and attention to detail are critical soft skills for managing projects and ensuring team safety. These skills and qualities are vital to ensure the safe, efficient, and compliant operation of gas systems in both residential and industrial environments.

What opportunities for professional growth are available for senior gas engineers within an organization?

Senior Gas Engineers often have various pathways for career advancement, including moving into managerial roles such as Gas Engineering Manager or Technical Director, or specializing further in areas like safety compliance, project management, or renewable energy integration. Many organizations also support ongoing professional development through training, certifications, and involvement in industry bodies. These opportunities not only deepen technical expertise but also enhance leadership and project coordination skills, making the role both dynamic and rewarding for those seeking long-term growth.

What is the difference between Senior Gas Engineer vs Gas Service Engineer?

AspectSenior Gas EngineerGas Service Engineer
CertificationsACS Gas Safe, relevant experienceACS Gas Safe, basic experience
Work EnvironmentSite inspections, project managementInstallation, maintenance, repairs
Employer & Industry UsageConstruction, utilities, large projectsResidential, commercial gas systems

Senior Gas Engineers typically have more experience and handle complex projects, site management, and oversight. Gas Service Engineers focus on installation, maintenance, and repairs of gas systems. Both roles require Gas Safe certification, but Senior Gas Engineers usually possess additional skills and responsibilities, making them suitable for supervisory or project-leading positions.

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 CO₂. 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.
  • Hands‑on 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.
