How to Apply for Wastewater Technology & Research Scientist

at CREW

🏢 About CREW

CREW appears to be a mission-driven company focused on innovative carbon dioxide removal (CDR) technology specifically applied to wastewater treatment. Unlike traditional wastewater companies, CREW uniquely integrates enhanced weathering processes with wastewater systems to optimize both treatment efficiency and carbon removal, positioning itself at the intersection of environmental chemistry and climate tech.

About This Role

This Wastewater Technology & Research Scientist role involves hands-on execution of both lab experiments (using instruments like ICP-MS and TOC analyzers) and field work at wastewater plants to refine CREW's enhanced weathering process. The position is impactful because it directly contributes to scaling a technology that could transform wastewater treatment into a significant carbon removal solution while improving treatment processes.

💡 A Day in the Life

A typical day might involve morning instrument calibration and sample analysis in the lab (using ICP-MS or TOC analyzers), followed by data interpretation from recent experiments on carbonate chemistry. Afternoons could include field visits to wastewater plants for sampling and in-situ measurements, or designing the next experimental approach to optimize the enhanced weathering process based on collected data.

🎯 Who CREW Is Looking For

  • Has hands-on experience with wastewater process design AND environmental chemistry, specifically in both lab and field settings
  • Can independently design experiments, analyze nitrogen cycling and carbonate chemistry data, and maintain analytical instruments like ICP-MS and IC
  • Demonstrates initiative to own projects from benchtop to plant-scale and drive them forward with minimal supervision
  • Possesses practical experience with wastewater sampling, in-field measurements, and interpreting data to optimize real-world systems

📝 Tips for Applying to CREW

1

Highlight specific wastewater treatment projects where you designed experiments AND conducted field measurements, not just lab work

2

Mention experience with the exact analytical instruments listed (ICP-MS, IC, TOC analyzers, spectrophotometers) and what you measured with them

3

Demonstrate understanding of enhanced weathering in wastewater contexts by referencing relevant research or projects

4

Show how you've used empirical data to optimize a process, specifically mentioning nitrogen cycling or carbonate chemistry

5

Emphasize instances where you took ownership of projects from design through execution to insights, matching the 'hands-on, initiative-driven' culture

✉️ What to Emphasize in Your Cover Letter

['Your hands-on experience with both wastewater process design AND environmental chemistry in lab AND field settings', 'Specific examples of designing and executing experiments that led to process optimization or scaling', 'How your work with analytical instruments (ICP-MS, IC, etc.) generated data that informed real-world decisions', "Why you're motivated by CREW's specific mission of integrating enhanced weathering with wastewater treatment for carbon removal"]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → CREW's specific enhanced weathering process and how it integrates with wastewater treatment (look for patents, white papers, or conference presentations)
  • → Current research on carbonate chemistry and nitrogen cycling in wastewater contexts, particularly related to carbon removal
  • → The regulatory and practical challenges of implementing new technologies in wastewater treatment plants
  • → CREW's team background and any published research or case studies showing their technology's impact

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through how you would design an experiment to test enhanced weathering's impact on nitrogen cycling in a wastewater plant
2 Describe your most challenging field sampling experience and how you ensured data quality under varying environmental conditions
3 How have you used ICP-MS or IC data to solve a wastewater treatment optimization problem?
4 What do you see as the biggest challenges in scaling enhanced weathering technology from benchtop to plant-scale?
5 How would you approach maintaining SOPs while also innovating on experimental design?

⚠️ Common Mistakes to Avoid

  • Focusing only on lab experience without demonstrating field work or plant-scale application
  • Using generic environmental science terminology without specific references to wastewater treatment processes or enhanced weathering
  • Presenting yourself as purely a researcher without showing ability to drive projects independently and deliver practical insights
