Senior Process Engineer – Electrochemical Reagent Generation

About the role

Lilac is seeking a Senior Process Engineer – Electrochemical Reagent Generation to own the technical evaluation, development, optimization, and integration of reagent generation technologies, including bipolar membrane electrodialysis (BPED), chlor-alkali, electrolysis, and other potential acid/base generation systems.

This role will serve as Lilac’s in-house technicalleadfor reagent generation and willbe responsible for advancing these technologies from laboratory testing and vendor evaluation through pilot- and demonstration-scale process design and ultimately commercial-scale deployment.

This is a highly collaborative and hands‑on position working across Technology, Engineering, Projects, and Operations to develop and deploy reagent generation solutions within Lilac’s overall process flowsheet.

This is a full‑time position with up to 25% domestic and international travel to pilot and project sites.

• Design and execute laboratory- and pilot-scale experiments to characterize andoptimizereagent generation systems.
• Develop a fundamental understanding of key equipment and operating tradeoffs, including reagent concentration, efficiency, energy consumption,membranelifetimeand equipment performance.
• Translate experimental findings into equipment requirements, operating parameters, and design criteria for pilot- and demonstration-scale systems.
• Evaluate interactions with upstream and downstream unit operations, including reagent storage,recycle streams, utilities, water balance, and waste streams.

• Lead technical evaluation and due diligence of reagentgenerationtechnologies and equipment suppliers.
• Critically assess vendor proposals, process designs, performance guarantees, equipment scope, and operating assumptions.
• Normalize vendor quotations to enable meaningful comparisons across technologies and suppliers.
• Develop structured technical recommendations for technology and vendor selection.

• Develop andmaintainCAPEX and OPEX models for reagent generation systems.
• Evaluate technoeconomic tradeoffs between technologies, vendors, system configurations, operating conditions, and integration strategies.
  
  Workcross-functionallytoidentifyreagent generation solutions that provide the best combination of cost, efficiency, reliability, and operability.

• Support the design, commissioning, and operation of pilot- and demonstration-scale reagent generation systems.
• Troubleshoot equipment and process performance in collaboration with vendors and internal teams.
• Translate operating experience into improved equipment specifications, design criteria, and operating strategies.
• Develop the technical basis for eventual commercial-scale deployment.

• Operate with a team-first mindset and contribute beyond reagent generation when projectsrequireit.
• Work effectively across internal teamsand external vendors.
• Be comfortable moving between hands‑on experimental work, equipment troubleshooting,technical analysis and process design.

• Bachelor’s Degree (or higher) in chemical engineering, mechanical engineering,materials science,chemistryor related field.
• Approximately 4-8years of relevant experience in electrochemical systems, membrane processes,process development, or related technologies.
• Hands‑on experience with pilot-, demonstration-, or commercial-scaleelectrochemical, membrane,reagent generation, or related process equipment.
• Strong process engineering fundamentals including process scale‑up, equipment integration, and technoeconomic analysis.
• Strong troubleshooting, communication, and cross‑functional collaboration skills.
• Pass a respirator fit test periodically, occasionally stand for up to 8 hours per day, occasionally move up to 50 lbs, and wear PPE.

• Direct experience with BPED/BMED, electrodialysis, chlor-alkali, electrolysis, or other reagent generation technologies.
• Experience scaling new process technologies from laboratory through pilot, demonstration, or commercial deployment.
• Experience with high‑TDS brinesor concentrated…
