If you enjoy working in a startup environment and are passionate about developing critical test systems for leading-edge satellite, spacecraft, and aerospace communication systems, we would like to hear from you.\nIn this position, you are responsible for the design, analysis, and implementation of engineering test plans and procedures. The ideal candidate possesses a strong combination of hardware and software knowledge with proficiencies in RF measurements, test equipment (VSAs, VSGs, VNAs, etc.), test architectures, and automation. The successful candidate will work closely with multi-disciplinary teams to address company-wide hardware test needs. Experience with phased array testing is preferred.\nCore day-to-day responsibilities include collaborating with design and test engineering teams to develop test requirements, mapping requirements to reusable test architectures and procedures, implementing test plans and procedures, and logging and presenting results to key stakeholders. Additional responsibilities include lab and equipment management and guiding key equipment purchase decisions.\nSenior-level test engineers are distinguished by an ability to architect RF test systems, to draw insightful conclusions from test results, and to participate in “design for test” planning and review from the early stages of RF product development. Test engineers are core members of the Cesium technical team.\nThe successful candidate will present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor of Science (BS) or higher degree in Electrical Engineering or Computer Engineering from an accredited university or institution.\nMinimum of 5 years of experience with a bachelor’s degree or 4 years of experience with a master’s degree. Industry experience in design, analysis, and implementation of RF test systems required. \nHigh proficiency with RF measurements (Linearity, NSD, EVM, etc.).\nTest architecture design and development including scripting, test executives, hardware, and measurement abstraction layers.\nProficiency with statistics and metrology as related to RF test design.\nHands-on experience with lab instruments such as digital oscilloscopes, spectrum analyzers, RF signal generators, and vector signal analyzers.\nExcellent written and verbal communication skills.\nPREFERRED EXPERIENCE\nFamiliarity or hands-on experience with phased array testing.\nProgramming or scripting experience (Python, MATLAB, C/C++, etc.)\nUnderstanding of RF and mixed-signal hardware (e.g. amplifiers, filters, ADCs/DACs, antennas) and its effects on test design.","description_format":"text","description_chars":2827,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Satellite Communications"],"lifecycle":[{"event":"open","at":"2026-09-23T23:04:14Z"}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":0,"expected_fill_days":65,"reasons":["conf:2","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-09-24T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/cesiumastro-senior-rf-test-engineer","json_url":"https://alion.io/job/cesiumastro-senior-rf-test-engineer.json","meta":{"generated_at":"2026-09-24T06:29:46Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers"}}
