Job description

About Us: At Quartermaster, we believe the ocean should be a safe and sustainably managed resource for all. By leveraging cutting-edge AI and robotics, we unlock capabilities that were only recently impossible. Our distributed open-ocean systems enable every vessel to sense, compute, and communicate, enhancing maritime domain awareness for those who need it most.

Job Description: Quartermaster is hiring a hands-on, versatile, and curious Junior Test Engineer for our new RF Test Lab in Columbia, Maryland. If you love working with Raspberry Pis, various sensors, microcontrollers, and software-defined radios, we want to hear from you. No two days will look the same: one day you might be building a test rig, the next you’ll be in the lab debugging hardware or analyzing RF data. Your work will feed directly into high-profile projects that help our customers succeed. We’re looking for someone who wants to build and test the next generation of maritime sensing systems.

Key Responsibilities:

  • Run RF tests on Quartermaster-designed systems, then analyze and document the results.

  • Write and carry out test plans and procedures.

  • Troubleshoot, rework, and repair electronics at the board and system level.

  • Support our developers with system-level testing as designs move toward production.

  • Help build out a brand-new lab, from setting up equipment to developing new test capabilities.

Qualifications (Preferred):

  • A bachelor’s degree in electrical engineering or a related technical field, or equivalent hands-on experience.

  • Experience with lab equipment such as spectrum analyzers, oscilloscopes, and vector network analyzers.

  • Soldering and hands-on assembly skills, including circuit-board-level work.

  • Some programming experience, ideally in Python.

  • Basic networking and computer configuration skills.

  • Clear, organized documentation habits.

  • Ideally, familiarity with schematic entry, PCB layout, and PCB fabrication and assembly.

  • Experience coordinating work across teams.

  • Mechanical skills are a plus.

Work Environment:

  • This is an onsite position in Columbia MD.

  • Flexible working hours with occasional deadlines requiring high availability.

  • Opportunity to work on innovative projects with a global impact.

  • Occasional day trips to HQ in Arlington (~ 3 days a month).

Benefits:

  • Competitive salary

  • Flexible work hours

  • Opportunities for professional development and continued education.
