Welder/Fabricator – Build the Backbone of Carbon Conversion Systems

Location: Franklin, TN (On-Site)
Type: Full-Time
Seniority: Skilled Trades

Join Enexor BioEnergy

Enexor is a venture-backed climate tech company just outside Nashville, TN, building modular systems that convert waste into renewable energy and carbon-negative outputs. We’re hands-on, hardware-first, and mission-driven—engineering real solutions to real-world problems.

Why This Role Matters

Our systems only work if they're built right. As a Welder/Fabricator, you’ll ensure that all fabricated assemblies meet spec, withstand pressure, and hold up in the field. This critical shop-floor work directly supports system performance, safety, and scalability.

What You’ll Do

• Weld carbon steel, stainless steel, Inconel, and other metal components using GTAW/TIG and GMAW/MIG processes
• Fit-up and fabricate pipe, tubing, and assemblies per drawings and tolerances
• Read and interpret blueprints, weld symbols, and process specs
• Prep materials—cutting, beveling, and cleaning to ensure proper fit and weld integrity
• Operate standard fab shop tools: saws, grinders, drills, fixtures
• Maintain shop safety, cleanliness, and documentation
• Assist with job staging, material handling, and movement of parts using forklift/mobile equipment
• Provide feedback on design for manufacturability and propose process improvements
• Support a wide range of business needs beyond fabrication, assisting cross-functional teams with prototyping, assembly, testing, and general operations as required to meet project and organizational goals.
• Communicate clearly and proactively with team members, engineers, and leadership to share progress, flag issues early, provide solutions, and keep projects moving efficiently.
• Demonstrate flexibility to support extended work hours or workweeks as needed to meet critical project deadlines or business priorities.
• Support and mentor junior fabricators; be a go-to technical resource

Requirements

• What We’re Looking For
• 5–10+ years of welding experience, focused on stainless steel and high-spec hardware
• High proficiency in TIG welding thin-wall pipe and structural elements
• Comfort with MIG processes and multi-pass welding
• Strong blueprint reading and fit-up skills
• Attention to detail and pride in clean, consistent welds
• Willingness to take feedback and adapt to a high-performance team culture
• Availability for overtime and occasional weekend work (7:00 am–3:30 pm core hours)
• U.S.-based only. No relocation assistance
• Bonus Points For
• Experience with Inconel or pressure-rated weldments
• Experience with laser welding (wire and fusion) and similar productivity improvement processes
• Background in energy, emissions, or industrial gas systems
• Familiarity with lean fabrication and continuous improvement
• Why You’ll Love It Here
• Mission with urgency
• Flat org, fast decisions
• Equity upside in a growing climate tech startup
• Hands-on, real-world product work
