Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.\nOur work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.\nAbout the Role\nAs RF Test & Validation Engineer, you own the characterization and validation of Harmattan’s in-house radio, from boards to integrated systems. You take RF measurement work off the designers’ plate and turn it into a repeatable, automated discipline: setups, measurements, and clear results fed back to the design team. You also keep the RF lab in working order as test capacity grows. You work primarily within the Radio team, with occasional exposure to other RF-based teams.\nResponsibilities\nRun RF characterization and validation of radio boards and integrated radio systems.\n\nBuild and maintain automated RF test benches, including interconnects, harnesses, and fixtures.\n\nDevelop reusable Python suites for instrument control and data capture across standard RF measurements.\n\nPerform pre-compliance and compliance-support measurements, including EMC and thermal testing.\n\nTest antennas, both standalone and integrated on systems.\n\nSupport the integration of the radio on our systems.\n\nAnalyze results, flag anomalies, and deliver clear, structured reports to RF designers.\n\nOwn the RF lab: track calibration, manage fixtures and accessories, and identify equipment gaps.\n\nSupport team members who are less experienced in RF testing.\n\nCandidate Requirements\nHands-on experience running RF characterization with VNA, spectrum analyzer, signal generator, power meter, AWG, and oscilloscope.\n\nSolid grasp of standard measurements such as S-parameters, P1dB, IIP3, sensitivity, and spurious.\n\nExperience building reusable test automation, Python preferred.\n\nSkilled in fine-pitch SMD and coaxial-cable rework on RF boards.\n\nCareful around input-power damage thresholds, protecting both instruments and devices under test.\n\nRigorous and perceptive: interprets results before reporting and spots anomalies early.\n\nWrites clear, structured reports.\n\nKeeps a shared lab tidy and works well alongside designers.\n\nWe look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.","description_format":"text","description_chars":2601,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military
