Position Overview:

Aclima is seeking a research scientist with expertise in particulate matter measurement and quantitative analytical and signal processing techniques. The job offers opportunities to design and execute experiments to test new sensor technologies in both the laboratory and the field and will involve routine hands-on work to build testing infrastructure.  To succeed at this position a candidate must demonstrate enthusiasm for quantitative assessment of data quality and measurement interpretation and associated computational skill. We are especially interested in candidates with experience working with low-cost sensors including optical and MEMS-based devices. The position calls for an approach that moves beyond empirical observations to assess technologies based on physical operating principles and the potential for biases across a range of operating conditions.

Aclima is a fast-paced work environment with a highly interdisciplinary team. During this phase of growth, we are seeking individuals who are self-starters and are excited about the opportunity to help us define our next steps across a variety of indoor and outdoor environmental applications. The exact responsibilities of the position will be tailored to the experience level of the successful candidate.


  • Familiarity with  traditional particle sensing technologies (gravimetric and real-time, e.g., OPC, TEOM, BAM, CPC, SMPS).  
  • Advanced degree in Chemistry, Environmental Science, Engineering, or Public Health with 3-5 years of experience with particulate matter measurement.  More experienced candidates interested in leadership opportunities are encouraged to apply.
  • Competency in data acquisition and analysis techniques and familiarity with basic scripting languages (e.g., Python, Matlab, R) .
  • Experience in signal processing (time series analysis, frequency domain, filtering, etc) and a strong foundation in statistical techniques (e.g. regression, model assessment, Bayesian parameter estimation, etc).
  • Strong grasp of air quality and aerosol fundamentals and associated human health impacts.
  • Deep familiarity with current academic research and governmental regulations.
