role
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 technical lead for reagent generation and will be 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.
What you'll do
Process Development, Integration & Experimental Work
- Design and execute laboratory- and pilot-scale experiments to characterize and optimize reagent generation systems.
- Develop a fundamental understanding of key equipment and operating tradeoffs, including reagent concentration, efficiency, energy consumption, membrane lifetime and 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.
Vendor Evaluation & Technical Due Diligence
- Lead technical evaluation and due diligence of reagent generation technologies 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.
Technoeconomic Analysis
- Develop and maintain CAPEX and OPEX models for reagent generation systems.
- Evaluate technoeconomic tradeoffs between technologies, vendors, system configurations, operating conditions, and integration strategies.
- Work cross-functionally to identify reagent generation solutions that provide the best combination of cost, efficiency, reliability, and operability.
Scale-up & Deployment
- 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.
Team Contribution
- Operate with a team-first mindset and contribute beyond reagent generation when projects require it.
- Work effectively across internal teams and external vendors.
- Be comfortable moving between hands-on experimental work, equipment troubleshooting, technical analysis and process design.
Qualifications
- Bachelor’s Degree (or higher) in chemical engineering, mechanical engineering, materials science, chemistry or related field.
- Approximately 4-8 years of relevant experience in electrochemical systems, membrane processes, process development, or related technologies.
- Hands-on experience with pilot-, demonstration-, or commercial-scale electrochemical, 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.
Preferred Qualifications
- 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 brines or concentrated electrolytes.
- Experience in lithium processing, DLE, brine processing, or other critical minerals applications.
