The Role

Transaera is seeking an Associate Test Engineer to support the day-to-day operation of the custom test rigs that power our R&D program. In this hands-on role, you will operate multiple test systems, improve their reliability and efficiency, analyze performance data, and provide recommendations based on your findings. Because our test rigs are designed and built in-house, we are looking for someone who is proactive, resourceful, and comfortable working independently. This is an entry-level opportunity, but candidates should have demonstrated experience with hands-on experimentation and problem-solving.

We're especially interested in individuals who:

  • Are excited about the future of climate technology.
  • Thrive in a fast-paced, growing startup environment.
  • Take initiative, solve problems proactively, and are not afraid to ask questions.

What You'll Own

Key Responsibilities include:

  • Operating custom test rigs including sample preparation, test execution, teardown, and reporting of results.
  • Improving rig reliability, calibration, throughput, and data collection, including automating routine measurements where practical.
  • Analyzing test data, identifying trends and anomalies, and presenting conclusions and recommendations to the engineering team.
  • Monitoring results as they are generated, investigating and resolving anomalies as they arise, and communicating findings and corrective actions.
  • Maintaining calibration schedules, standard operating procedures, and test documentation.
  • Supporting prototype builds and materials trials alongside the chemistry and manufacturing teams.
  • Contributing to fixture and rig design and fabrication (CAD, 3D printing) as opportunities arise.

What we're looking for:

  • BS in mechanical engineering, chemical engineering, physics, or a related field. Recent graduates welcome.
  • Hands-on experience with custom or instrumented test setups from a research lab, co-op, internship, or engineering project team.
  • Experience carrying experiments from design through execution and analysis of your own data (Python, MATLAB, or Excel).
  • Demonstrated ability to work independently: troubleshoot unexpected results, identify root causes, and resolve issues before escalating.
  • Strong attention to detail in record-keeping and documentation.
  • Comfortable with hand tools, basic wiring, and daily hands-on lab work.

Bonus points:

  • Parametric CAD (SolidWorks, Onshape, or Fusion 360) and rapid prototyping experience such as 3D printing.
  • Coursework or applied background in thermodynamics, fluid mechanics, or heat and mass transfer; psychrometrics a plus.
  • Data acquisition experience: LabVIEW/NI hardware, Arduino or Raspberry Pi instrumentation, sensor selection and integration.
  • Prior experience at a startup or in a small-team environment.
  • Ground-floor opportunity to define a critical function at a fast-growing startup
  • Competitive salary + meaningful equity in a VC-backed company
  • Work directly with founders, executives and have a real seat at the table
  • Mission-driven work to help bring about a revolution in HVAC technology

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
