Senior R&D Scientist

Chicago, IL
Did you know that over 30% of fresh produce grown in the world goes to waste and never reaches consumers?

Interested in using science to create a social impact? Hazel Technologies is searching for a highly motivated and skilled Senior R&D Scientist to help us fight global food waste with sustainable science.

Hazel Technologies, is seeking an exemplary innovator to apply materials science, chemistry, and process engineering to help us enhance our products and build new technologies for reducing agricultural waste. Our Senior R&D personnel are expected to bring strong technical skills to the table as well as the ability to ideate, innovate, and execute on current and new product development. Our R&D personnel operate in a multidisciplinary context, combining elements of chemistry, engineering, and food science to put Hazel products at the forefront of innovation in the preservation of perishable goods.

Owing to the multidisciplinary nature of the position, chemical engineers, chemists, and material scientists with advanced degrees in their related discipline and passion for invention are encouraged to apply. Independence and motivation are essential.

The benefits of this position you should consider as an applicant are: 

  • Get in on the ground floor. You will become an early team member at one of the fastest growing startups in Ag-Tech, according to American Inno’s “Top Green Tech Startups to Watch”
  • Create an impact. Solve the problems of tomorrow: you will be helping to save food every day that would have gone to waste. Hazel Tech has received the prestigious USDA Phase II SBIR Grant, $600,000 in federal funding given only to the most impactful technologies in the future of the agricultural industry.


The Senior R&D Scientist is expected to be a contributor of new ideas and methods to the product portfolio at Hazel technologies through innovation in production and in new product development. They will utilize their technical knowledge and understanding of experimental design to deploy new ideas in Hazel’s labs and rigorously test their viability as marketable products.

The Senior R&D Scientist is expected to make tangible improvements to current Hazel production processes using their knowledge of reactor design, kinetics, flow dynamics, and experiment design.  

They will oversee and contribute to formulations work by existing Hazel staff. They are expected to regularly report progress to management and generate internal white papers with results in real-time. They will be entrusted with responsibilities related to maintaining and directly contributing to Hazel technologies’ intellectual property.

They will operate wet chemical processes at scales from analytical to commercial. This includes operating batch and semi-batch reactions as well as formulations on the gram to multi-kilogram scale.  

Working with the existing production and quality control team they will contribute to the manufacture of existing products, the development of new ones, and the analytical assessment of product quality and reproducibility on a commercial scale.

The Senior R&D Scientist will work with a multidisciplinary team, including direct reports at the laboratory level that will assist with experimental design and execution. They will independently manage R&D personnel and projects, including applicable grant resources.

Fluency in gas chromatography, materials characterization methods, polymer science, and SOP development are essential.  Experience with batch or semi-batch reactors, synthetic chemistry, sorption chemistry, and liquid-solid or gas-solid interfaces is strongly preferred.

This position will work closely with post-harvest plant physiologists and other food scientists within Hazel and externally to build in feedback from the field.  

Requirements for Position:

  • Strong Communication Skills in English
  • For Scientists: Ph.D. Required
  • For Engineers: Masters or notable work experience in chemical process engineering
  • Sample technical writings (publications, posters, patents etc.)
  • Experience with Gas Chromatography
  • Relevant experience in Reactor Design
  • Experience with liquid-solid or gas-solid interfacial and sorption phenomena
  • Comfort with independent, largely self-managed research
  • Capable of leading a small team of researchers

Recommended but not required:

  • Native-level Foreign Language Skills – Spanish, Portuguese, Dutch, French, Italian
  • Industrial experience strongly preferred
  • Notable experience in process scale-up
  • Experience in food science or agricultural science, especially fruits and vegetables
  • Exposure to the patenting process
  • Experience with biopesticides, biocides, or plant growth regulators
  • Experience with microbiology
