Job Description

We have an opening for a Waste Treatment Process Engineer.  You will be responsible for performing activities associated with waste treatment, process optimization, equipment troubleshooting, waste characterization, and ensuring compliance with disposal criteria and land disposal restrictions of final form waste. You will be responsible for interpreting Resource Conservation and Recovery Act (RCRA) regulations and DOE Orders pertaining to the management of radioactive and hazardous waste. You will be part of a close knit but diverse team of highly qualified waste treatment personnel with the common goal of treating as much of LLNL’s varied wastes as safely and efficiently as possible.  This position is in the Radioactive and Hazardous Waste Management Program.

This position will be filled at either the TSS.1 or TSS.2 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

In this role you will

  • Qualify on each waste treatment unit operation at the Decontamination and Waste Treatment Facility (DWTF).
  • Qualify as a Characterization Chemist and/or Radiological Characterization Analyst for WTG.
  • Perform process and systems engineering as they pertain to waste treatment activities and integration of facilities infrastructure with treatment unit operations.
  • Apply practical and theoretical knowledge of techniques in solidification/stabilization technologies, including leachate prevention, monolith formation, and free liquid elimination. 
  • Apply knowledge and techniques of organic adsorption and destruction, precipitation, flocculation, filtration, and evaporation, to accomplish aqueous waste treatment. Other methods of waste treatment which may be applied, include decontamination and size reduction, debris washing, shredding, surfaces cleaning, reactive wastes processing including water reactive and pyrophoric deactivation, and passivation techniques.
  • Track waste inventory and certification, ensuring that data development tools meet the needs of the Waste Treatment Group.
  • Assist senior engineers with maintenance and repair of  programmatic equipment including sensor calibration, pipe & tube fittings, ventilation, fume hoods, glove boxes, programmable logic controllers, process off-gas filtration, neutralization, and adsorption.
  • Assist senior engineers with management and execution of larger waste treatment projects, as requested.
  • Perform other duties as assigned.

Additional job responsibilities at the TSS.2 Level

  • Perform characterization on moderately complex waste matrices and make determinations of treatability through DWTF.
  • Review and validate moderately complex data to assure quality of information on regulatory and DOE reports.
  • Interpret and apply moderately complex State and Federal regulatory compliance requirements to start-up, new and existing processes, and operations.


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Bachelor’s degree in Engineering (e.g., nuclear, mechanical, civil/structural, chemical), Physics, Chemistry, or Materials Science, or equivalent combination of education and related experience.
  • Advanced verbal and written communication skills necessary to effectively collaborate in a multidisciplinary team environment and to present and explain technical or operational information and work results.
  • Proficiency with computers and ability to rapidly learn and use new software.
  • Demonstrated organizational skills.
  • Ability to become medically qualified to wear respiratory and protection equipment.
  • Experience working in analytical laboratories, following laboratory procedures, quality assurance, and lab safety protocols. 
  • Experience interpreting analytical data to make chemical treatment or operational process decisions and develop waste processing routines that yield final form wastes. In addition, using analytical data to certify wastes for disposal.
  • Experience designing, performing, and reporting on bench-scale experiments, especially as applied to testing wastewater treatment processes.
  • Experience interpreting local, State, Federal and/or other complex laws/regulations to achieve compliance. Of distinction are waste regulations related to RCRA for Treatment Storage and Disposal Facilities (TSDF).

Additional qualifications at the TSS.2 Level

  • Experience with PLC programming. Familiarity with PLC ladder logic, hardware maintenance, data logging, system conversions, ethernet networking, etc. 
  • Advanced computer skills: programming languages and platforms such as visual basic, C++, java, Arduino, etc.; developing applets and integration with SQL databases; CAD programs.
  • Experience troubleshooting, repairing, visualizing, designing, and installing complex mechanical systems, including at a “hands on” level.
