Head of Technical Solutions

About the Role

The Head of Technical Solutions sits at the intersection of technical expertise and strategic relationship-building. This role brings deep wastewater treatment knowledge to CREW to scale our technology and to engage with utilities, municipalities, and industry partners — shaping how our technology is understood, evaluated, and adopted in the market. This role will also support the Engineering, Operations, and R&D teams to continue to push forward product development, how CREW’s systems operate with performance expected by utility partners, and ensuring hardware systems are best designed, procured, and integrated with our wastewater utility partners.

This role will work closely with CREW’s world-class Advisory team and CEO to define scientific priorities, mentor science team members, and drive CREW’s mission through innovative research and rigorous analysis. CREW is a fast-moving, technically ambitious company – this role is for someone who wants to shape the technical direction of a category-defining technology.

This position is a full-time role. Location is onsite at CREW’s Brooklyn, NY office. Remote considered only for exceptional candidates, with regular travel to Brooklyn expected.

Responsibilities

• Serve as CREW’s primary technical subject matter expert in utility-facing engagements.

• Lead technical scoping conversations with utility engineering and operations teams, translating CREW’s biological treatment technology into the context of their specific process needs, infrastructure constraints, and discharge requirements.

• Lead technical support for RFP/RFQ responses, contributing process-level framing and technical positioning, while developing repeatable tools and resources that enable the broader team to support future opportunities.

• Conduct and oversee preliminary site assessments and technical fit evaluations for prospective deployment sites, personally leading strategic or complex opportunities while helping establish scalable qualification processes.

• Help shape the growth of CREW’s technical solutions capability by mentoring future team members, refining customer engagement processes, and contributing to hiring, onboarding, and organizational development as the team expands.

• Identify, develop, and manage strategic partnerships with utilities, municipal water authorities, engineering firms, and co-deployment partners.

• Work in close coordination with the Commercial Team to own senior-level relationships at target accounts — utility directors, chief engineers, operations leads — particularly trust-based, multi-year partnerships that require sustained senior engagement.

• Contribute to CREW’s external technical positioning via white papers, abstracts, peer-review papers, presentations — helping shape how the company talks about its technology with the engineering and operations community.

• Contribute process and mechanical engineering judgment across both design review and active deployments — a technical resource for Operations and Wastewater Engineering when design or field questions arise.

Experience Requirements

• Bachelor’s degree (required) in Environmental Engineering, Chemical Engineering, Civil Engineering, or a related field; a Master’s or PhD degree is a bonus.

• 10+ years of experience in wastewater process engineering, biological treatment design, or related fields.

• 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.

• Exceptional technical writing skills, with the ability to translate complex process science into clear, defensible documents for utility executives, consulting engineers, and other stakeholders.

• Familiarity with process modeling tools (BioWin, SUMO, GPS-X, ASM libraries, or equivalent).

• Familiarity with analytical methods used in wastewater and aqueous chemistry system characterization (e.g., IC, TIC, ICP) and ability to interpret analytical data.and experience with statistical programming and modeling (e.g., Python, R, MatLab).

• Comfortable working in a rapidly evolving work setting and able to quickly synthesize new information to proactively adjust focus and maintain high-impact results.

• Ability to travel 20-50% to project sites.

• Professional Engineer (PE) license is a plus.

• You practice extreme ownership (no task is too small).

• You love being in the trenches with your team and working with high empathy.

• You have a growth mindset.
