We’re looking for experienced hardware & firmware engineers to work on every stage of bringing new devices to market. Our devices are part of a global network that monitors air quality to solve big health and climate challenges. Your work will help bring cleaner air to the world.

The Work

Our devices are typically solar powered with a cellular interface for relaying data to the cloud. We measure the world with a variety of environmental sensors. We also allow accessory modules to plug into our hardware platform to enhance its sensing capability. Your job will be focused on the development/production of this hardware platform and the integration of these accessory modules. You will be responsible for all aspects of the hardware design, including system design, parts selection, schematics capture, PCB design, manufacturing, and testing.

The ideal candidate should have:

  • Minimum 3 years of relevant industry experience bringing high quality hardware from requirements collection and ideation to the market in volume
  • Experience with schematic capture and PCB layout using tools such as Altium Designer
  • Experience with low noise analog design, power management, and battery management
  • Experience working with wireless technologies such as LTE
  • Experience with various communication interfaces such as UART, I2C, SPI, 4-20mA, RS485, etc
  • Experience with simulating circuits using SPICE based tools such as LTSpice
  • Experience with ESD/EMI compliance, signal integrity rules, safety testing and various other DFM requirements
  • Excellent lab skills: oscilloscopes, logic analyzers, power supplies, electronic loads, etc
  • Excellent communication and verbal skills

We’d love to also see the following in the ideal candidate, but if you don’t have it, we’ll help you learn it

  • Experience with writing production grade firmware in C/C++ (and sometimes assembly)
  • Familiarity with long-term reliability testing
  • Experience with sensor data analysis and sensor selection
  • Experience with hand-soldering surface mount components for running quick tests to validate your design
  • Experience with writing modular, scalable and testable code in python for automation, testing and data analysis
