Job Description

You are start-up compatible, excited about the challenge to make an impact in the cleantech energy sector, that accelerates the adoption of power electronic systems across renewables.


  • Analyze component failure signatures of solar inverters ranging from 4kW to 4MW
  • Model popular inverter architectures, and simulate their failure characteristics
  • Perform Failure Method and Effects Analysis (FMEA)
  • Develop mixed-signal and digital signal-processing techniques to improve signal quality
  • Develop test designs for accelerating failure of inverters and our data acquisition systems
  • Design and build our next-gen embedded data aquisition and processing platform.


The candidate must have experience with high-voltage solar, battery energy storage, or EV chargers or power-train inverters, and possess safety relevant experience working with 1,000V systems at 1,000 A current levels.
A strong background in mixed-signal systems, signal analysis, signal-processing, noise and signal filtering and decimation techniques, rounds out your solid understanding of various control schemes and configurations used by inverters. A basic understanding of the featurization process for time-series data, e.g. electrical signals, that are processed by Machine Learning algorithms, is a plus as you wll be closely working with a data engineer/scientist.

The ideal candidate has followed a complete cradle-to-grave life cycle of an inverter, including accelerated life tests, and possesses good command of suitable analytics and modeling tools, such as

  • SPICE,
  • Matlab/Octave,
  • Ansys’ multi-physical modeling suite,
  • Python coding for data analysis,
  • Schematic capture and layout for high-speed data-acquisition systems.

You will come in at the ground level to build the foundation of a hardware-enabled data platform that makes renewable energy more reliable and affordable. As an early member of the team, you report to the CEO of the company (we are small team!).

Energy is essential for our lives, and we are ensuring it is delivered reliably from renewables such as solar power and energy storage systems, to be consumed by Electric Vehicles on the road and in the sky. All rely on power electronics at the heart of each system. infiniRel's "EKG", or Energy Kardio Graph(tm), is similar to a heartmonitor that enables unprecedented insights into the health of each system to avoid black-outs from Inverter-Based Resources, and significant financial losses that slow down rapid adoption. An award-winning start-up headquartered in San Jose, CA we have  operations in Chicago, IL, Tucson, AZ, and Germany. While the candidate’s co-location with any of the above locations is preferred, the company offers remote home office, and you are able to travel 10% of the time (domestic).

At this time the company is not in a position to offer full relocation or visa sponsorship.

The company offers Restricted Stock Units commensurate with your expertise, compensating for a reduced cash component of your initial compensation, vesting based on time and completed milestones. Your cash components will be matching the funding and revenue levels of the company, which will require you to be financially flexible during the first phase of the project. When considered as a full-time employee at partial salary plus equity, we also offer medical and dental insurance. You will have the opportunity to participate in our self-directed infiniRel 401(k) plan, and additional benefits as we build revenue and secure additional funding.

infiniRel lives at the nexus of analog high-performance sensing, Digital Signal Processing, machine learning, cloud and edge computing. Interested to join the infiniRel team? Talk to us and send your list of relevant accomplishments and your motivation to
