We are a small, happy crew of hard working folks. We believe that our products will make a positive impact in the world and when you get down to it, that’s why we like coming to work every day. It helps that we also genuinely enjoy each other’s company. We value silliness, integrity and good, hard work.

Around here, everyone contributes their ideas and no one is above clearing a printer jam. We are not big on titles, levels or egos but we are very big on listening, collaborating and meeting our goals--and our goals are ambitious. There is a lot to do and we need smart, creative, friendly people to help us get it done.

Ripple is looking for a Senior Manufacturing Engineer who has experience implementing food and/or biological manufacturing processes at pilot and manufacturing scale. In particular, we are looking for a candidate who can lead the design review, start-up, and commissioning of a new production line at our manufacturing plant. This position requires experience with cGMP production systems, technical transfer of food or pharma processes, and a willingness to travel. You will need to lead various scale-up efforts, including process equipment design/sizing, technical transfer of processes, and process optimization.


  • Offer technical guidance, engineering insight as well as hands-on execution for new process development
  • Develop, scale and transfer protein purification process to contract manufacturing sites
  • Help with selection, validation, maintenance and troubleshooting of process development equipment
  • Play the role of janitor, receptionist, IT-person, printer-jam-clearer, and general pitcher-inner alongside everyone else at Ripple.


The ideal candidate will have >7 years of industry experience in food or biological process engineering and a degree in an engineering field as well as: 

  • Understanding of the underlying chemistry in biochemical separations
  • Experience designing sanitary processes and systems for food processing
  • An enthusiasm for doing it all, from equipment and process design to hands-on systems implementation.
  • You will need solid communication skills, and the ability to communicate your work to scientists (with and without food backgrounds) and business people alike.  This job will require travel up to 40% of the time.
  • Finally, you need to be ready to roll-up your sleeves and do whatever needs to be done, because this is the early stage of a start-up.

 Bonus points if you have:

  • In-depth knowledge of solid/liquid separations in protein processing (pure or mixed fractions)
  • A background automating manufacturing processes, including design and installation of control systems
  • Experience using data analysis and statistical approaches in process development
