HVAC Field Technician

Helix Earth | Houston/Jersey Village, TX 77040

We're building technology invented at NASA to solve one of HVAC's most overlooked problems: humidity. Our CEO, Dr. Rawand Rasheed, developed this technology while at NASA, was named to Forbes 30 Under 30 for Energy and Green Tech, and we're now commercializing it at scale. This is a rare chance to get in early on a clean tech startup with real traction.

We're looking for an experienced HVAC Field Technician to own end-to-end pilot deployments: building units, instrumenting sites, installing and commissioning systems, and keeping them running through the trial period. Hands-on role. Real ownership. Direct impact on how our technology performs in the field.

What You'll Do

Pilot Build and Installation

• Assemble and modify POC pilot units from the ground up: mechanical assembly, plumbing, basic wiring, fit-up, and rework
• Support site installs and commissioning including rooftop and RTU work, ducting interfaces, mounts, curbs, supports, weatherproofing, and startup checks
• Coordinate with electricians and HVAC contractors on site
• Assist with electrical and controls integration: routing, strain relief, and termination under supervision

Instrumentation and Data

• Own pilot instrumentation logistics: prepare, label, and organize sensors and DAQs for each site
• Install sensors on and around RTUs, verify operation, and document placement
• Perform basic calibration and verification checks per test plans
• Support data logger setup and field networking

Maintenance and Troubleshooting

• Maintain deployed systems throughout the pilot: routine inspections, preventive maintenance, troubleshooting, part swaps, and rapid response to issues
• Perform root cause analysis on failed systems and recommend corrective actions
• Provide design feedback on sub-assemblies to engineering

Documentation

• Maintain clean field documentation: as-builts, photos, wiring and plumbing notes, sensor maps, and service logs
• Manage field readiness: tools, spares, consumables, packing lists, and site access requirements

What We're Looking For

Required

• 5+ years of hands-on HVAC, refrigeration, mechanical service, or adjacent field technician experience
• Comfortable working on rooftops and in mechanical spaces with strong safety habits
• Proven ability to troubleshoot mechanical systems: airflow, ducting, pumps, valves, seals, leaks, vibration, and basic electrical symptoms
• Brazing and/or welding experience (or demonstrated ability to learn quickly)
• Strong organization and ownership mindset
• Willingness to travel to pilot sites including multi-day stays

Preferred

• EPA 608 certification or ability to obtain quickly
• Familiarity with measurement instruments: temperature/RH, pressure, airflow, CO2, power metering, flow meters
• Experience building prototypes, test rigs, or one-off equipment
• Basic experience with data loggers and field networking
• Comfort reading wiring diagrams, P&IDs, and mechanical drawings

What Success Looks Like (First 90 Days)

• Can independently prepare a pilot kit for deployment
• Executes clean sensor installs with repeatable labeling and documentation
• Supports at least one pilot deployment with minimal rework
• Establishes a reliable field service cadence: logs, photos, issue tracking, spare-part discipline

Physical Requirements

Frequent rooftop and mechanical lab work. Must be able to lift 50 lbs, climb ladders, and work in hot and cold weather.

Benefits

• Equity in the company
• Health, dental, and vision insurance
• 401(k) with employer matching
• Flexible time off
• Direct exposure to leadership and strong growth potential
