About the Role
As a Wastewater Process Engineer, you will contribute to process design, optimization, and technical implementation of CREW’s process intensification and carbon removal systems at wastewater treatment facilities. You will use your knowledge of process modeling and engineering, aqueous chemistry, and wastewater operations to design and optimize dosing systems that achieve both treatment efficiency and measurable greenhouse gas. This role facilitates CREW’s scientific and engineering innovations into scalable, real-world systems, analyzing and interpreting data to identify opportunities and drive action. This is an ideal opportunity for a process-minded, mission-driven engineer who thrives at the intersection of environmental technology and practical system design.
Responsibilities
- Develop process flow diagrams, mass and energy balances, and dosing system designs to meet project goals.
- Coordinate with the Technology and Operations teams to translate lab results and field data into insights and actions.
- Collaborate with the Technology team to address process issues and propose technical solutions to wastewater partners.
- Serve as a technical lead for wastewater process and process-mechanical support during partner engagements.
- Work with the Operations team to set process optimization and carbon removal targets.
- Own technical documentation, training, and design input to internal teams and external partners.
- Support new project development, including alkalinity dosing design, integration into existing facility systems, and process control strategy.
- Champion operational and process insights to inform project development strategy with the Commercial Team.
- Stay current on emerging trends in wastewater treatment, process intensification, sustainability, and environmental technology.
Requirements
- Bachelor’s degree in Environmental Engineering, Chemical Engineering, Civil Engineering, or a related field.
- 5–8+ years of experience in wastewater process engineering, biological treatment design, or related fields (municipal or industrial).
- Strong understanding of wastewater treatment processes, including nutrient removal, solids handling, and pH and alkalinity control.
- Experience developing and reviewing PFDs, P&IDs, site layouts, mass balance calculations, and process unit design.
- Comfortable working in a rapidly evolving startup setting and able to quickly synthesize new information to proactively adjust focus and maintain high-impact results.
- Ability to travel periodically to deployment sites.
- Practice extreme ownership.
- Love being in the trenches with your team and working with high empathy.
- Have a growth mindset.
