Overview PNNL's Earth System Science Division enables energy independence and national security through leadership in earth systems science, engineering, and decision analytics. Our work focuses on solving complex problems in the dynamic Earth system. Our interdisciplinary scientists steward a breadth of efforts that encompass research on plants to groundwater science and coastal zones, to storm prediction. Our research focuses on understanding and mitigating operational risks at the interface of human and natural environments. This includes predicting the impacts of natural hazards and extreme climate events on Earth and human systems, along with the impacts of wildfire, flooding, sea level rise and storm surges. We focus on understanding and mitigating environmental contamination and increasing the resiliency, security and sustainability of water resources. We provide geointelligence through advanced sensing and data analytics to forecast complex system behaviors and operational performance to understand human-natural systems. This includes informed decision making and enhanced community resilience, advanced monitoring, and remote sensing of environmental systems for energy and national security. It also includes developing energy systems, including geothermal energy, sustainable oil and gas production, storage and utilization, along with carbon sequestration. Driven by a “science-to-solutions” philosophy, we provide scientific leadership and technology to enhance national security, mitigate natural hazards and optimize disaster response. In the critical areas of energy, environment, intelligence, and defense, we deliver insights and decision support through the development of tools and solutions. Responsibilities The Environmental Sensors team within the Earth System Predictability & Resiliency Group (ESSD) is seeking a highly motivated Postdoctoral Research Associate with a background in mechanical engineering to support and lead key interdisciplinary research efforts. This position will contribute to several innovative projects focused on environmental monitoring, renewable energy, and advanced sensing technologies. Development of Advanced Sensing Systems Design and prototype next-generation sensors for Earth system science and renewable energy applications. These systems will be lightweight, compact, soft, and capable of operating in extreme environments such as the deep subsurface, Arctic regions, and chemically reactive settings. Focus areas include improving sensor accuracy, speed, adaptability, and system versatility. Environmental Monitoring for Renewable Energy Support efforts to evaluate the ecological impacts of conventional hydropower and marine/hydrokinetic energy systems. This includes developing and deploying underwater acoustic telemetry tools for detecting and tracking aquatic species such as fish and marine mammals. Wildlife Impact Studies Contribute to research that mitigates the environmental impacts of energy infrastructure by designing and implementing radio telemetry systems for monitoring bats and birds. Energy Harvesting for Remote Sensors Design and develop advanced energy-harvesting technologies to power remote sensing platforms and miniaturized transmitters, enabling long-term autonomous monitoring in remote or hard-to-access environments. Core Responsibilities: Design, fabricate, and test advanced mechanical and electronic sensing systems Perform digital signal acquisition and sensor validation in laboratory and field environments Analyze complex environmental datasets and contribute to sensor performance modeling Support the development of intellectual property and patent applications Author high-impact research publications and contribute to scientific reports and presentations Qualifications Minimum Qualifications: Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university Preferred Qualifications: Ph.D. in Mechanical Engineering, Materials Science, or a closely related field Proficiency in Micro-Electro-Mechanical Systems (MEMS) fabrication Hands-on experience working in cleanroom environments for sensor manufacturing Strong background in instrumentation and system integration Hazardous Working Conditions/Environment Must be comfortable working in the field, including on a research vessel.

About PNNL Pacific Northwest National Laboratory (PNNL) is a world-class research institution powered by a highly educated, diverse workforce committed to the values of Integrity, Creativity, Collaboration, Impact, and Courage. Every year, scores of dynamic, driven people come to PNNL to work with renowned researchers on meaningful science, innovations and outcomes for the U.S. Department of Energy and other sponsors; here is your chance to be one of them! At PNNL, you will find an exciting research environment and excellent benefits including health insurance, and flexible work schedules. PNNL is located in eastern Washington State—the dry side of Washington known for its stellar outdoor recreation and affordable cost of living. The Lab’s campus is only a 45-minute flight (or ~3 hour drive) from Seattle or Portland, and is serviced by the convenient PSC airport, connected to 8 major hubs. Commitment to Excellence and Equal Employment Opportunity Our laboratory is committed to fostering a work environment where all individuals are treated with fairness and respect while solving critical challenges in fundamental sciences, national security, and energy resiliency. We are an Equal Employment Opportunity employer. Pacific Northwest National Laboratory considers all applicants for employment without regard to race, religion, color, sex (including pregnancy, sexual orientation, and gender identity), national origin, age, disability, genetic information (including family medical history), protected veteran status, and any other status or characteristic protected by federal, state, and/or local laws. We are committed to providing reasonable accommodations for individuals with disabilities and disabled veterans in our job application procedures and in employment. If you need assistance or an accommodation due to a disability, contact us at [email protected]. Drug Free Workplace PNNL is committed to a drug-free workplace supported by Workplace Substance Abuse Program (WSAP) and complies with federal laws prohibiting the possession and use of illegal drugs. If you are offered employment at PNNL, you must pass a drug test prior to commencing employment. PNNL complies with federal law regarding illegal drug use. Under federal law, marijuana remains an illegal drug. If you test positive for any illegal controlled substance, including marijuana, your offer of employment will be withdrawn. Security, Credentialing, and Eligibility Requirements In accordance with Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, new employees are required to obtain and maintain a HSPD-12 Personal Identity Verification (PIV) Credential. To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws. For foreign national candidates: If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO)risk determination to maintain employment. Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment. Mandatory Requirements Please be aware that the Department of Energy (DOE) prohibits DOE employees and contractors from having any affiliation with the foreign government of a country DOE has identified as a “country of risk” without explicit approval by DOE and Battelle. If you are offered a position at PNNL and currently have any affiliation with the government of one of these countries, you will be required to disclose this information and recuse yourself of that affiliation or receive approval from DOE and Battelle prior to your first day of employment.
