About Zero Carbon Systems

Zero Carbon Systems (ZCS) is a clean energy and direct air capture company on a mission to accelerate the transition to a zero carbon future. We are developing and deploying breakthrough technologies designed to reduce atmospheric CO2 at scale, addressing one of the most pressing challenges of our time.

Backed by mission aligned investors and led by a team of passionate innovators, ZCS sits at the intersection of cutting edge science and real world impact. We are building a diverse, collaborative, and driven team of individuals who share our commitment to excellence, creativity, and the belief that the work we do today will shape the world of tomorrow.

If you are energized by meaningful work and want to be part of a company where your contributions directly advance the clean energy transition, we would love to hear from you.

Zero Carbon Systems seeks an Engineering Technician to support the mechanical engineering team in building, modifying, and troubleshooting the test rigs and prototype equipment behind our Direct Air Capture (DAC) technology. Working side by side with our senior mechanical engineers, you will turn drawings and models into working hardware - assembling instrumented pneumatic and hydraulic test rigs, fabricating custom parts, and helping run the tests that validate new designs.

This is a hands‑on role for someone who is comfortable moving between a fabrication bench, a 3D printer, and a live test rig in the same day, and who takes pride in clean, leak‑tight, well‑documented work. As a startup, we are looking for a flexible team member who can shift priorities quickly and contribute wherever the build schedule needs them. This is a full‑time, on‑site position on a standard day shift based in Brighton, CO, reporting to the Director of Mechanical Engineering.

• Assemble test rigs, sub-systems, and prototype equipment from engineering drawings, Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), and 3D CAD models.

• Build and modify pneumatic and hydraulic test rigs operating in the 10 to 200 psi range, including routing, supporting, and leak‑checking complete fluid circuits.

• Fabricate stainless steel tubing assemblies - cutting, deburring, bending, and making up compression, NPT, and related fittings to leak‑tight standards.

• Fabricate custom parts and fixtures using shop hand tools, power tools, and machine tools.

• Produce parts on FDM 3D printers, including preparing and slicing models, selecting print parameters, post‑processing, and assembling printed components into larger structures.

• Troubleshoot existing rigs to isolate leaks, instrumentation faults, and mechanical failures, and carry out repairs and rebuilds.

• Support test campaigns by setting up instrumentation, collecting data, and maintaining accurate records of configurations, runs, and results.

• Work with engineers to identify design, operability, and maintainability issues discovered during build and test, and propose practical improvements.

• Maintain shop equipment, tooling, and consumable inventories of fittings, tubing, and hardware.

• Follow and help enforce company and OSHA safety procedures, including PPE, lockout/tagout, and safe handling of pressurized systems.

• Contribute to clear build documentation, including as‑built markups, assembly notes, and Standard Operating Procedures.

• Associate's degree in Engineering Technology or a related field with 3+ years of relevant hands‑on experience, or 10+ years of experience in an R&D, prototype, or fabrication environment.

• Ability to read and work from engineering drawings, PFDs, and P&IDs.

• Demonstrated safe and proficient use of hand tools and power tools.

• Experience assembling fluid…
