Remote Seismic Observer Jobs (NOW HIRING)

We are seeking an Applied Mission Engineer to join a multidisciplinary team supporting the Department of Homeland Security (DHS) Customs and Border Protection (CBP) Program Management Office (PMO). This role is ideal for engineers who are passionate about applying technical expertise to real-world national security challenges and advancing mission-critical capabilities through research, evaluation, and informed decision-making. This position requires U.S. citizenship and the ability to obtain a CBP Background Investigation (BI) is required; active CBP BI preferred. This position requires 20% travel that may entail remote and rugged areas.

The Applied Engineer will work closely with CBP stakeholders, program managers, and technical experts to assess technologies, guide development efforts, inform program strategies, and enable effective deployment of integrated systems. This includes both field-focused technical assessments and the development of supporting engineering and programmatic documentation. The ideal candidate has experience with research, development, test, and evaluation (RDT&E), and can bridge the gap between emerging capability and mission utility.
