OffWorld was founded by an experienced engineering team drawing on decades of tackling formidable engineering challenges at NASA, ESA, SSL/MDA, CERN, Reaction Engines, SAFRAN, Surrey Satellites and Cisco. OffWorld’s first challenge is developing and maturing a modular robotic system for extreme environment applications on Earth--our robots will go deeper underground than humans can, eliminate the need for humans to work in life-threatening environments in construction, tunneling and other dangerous applications and dramatically reduce the environmental footprint and cost in key industrial sectors.\nWe have designed a modular robotic architecture that focuses on maximizing the commonality and reusability across components for fast deployment and optimization. Our robotic systems combine sensory information with cutting edge machine learning (ML) for control and decision making.\nWe are currently looking for an experienced and technically creative Senior RF test Engineer who contributes to the designs, development, and implementation of testing methods and equipment.\nThe successful candidate, as a minimum, should exhibit proven capabilities in the following:\nMSc or higher in Electrical Engineering or equivalent (PhD is preferred) with at least 7 years of professional experience.\nPhased array antenna system modeling, design analysis, and concurrent engineering with a fast-paced multi-disciplinary team, interacting with electrical, Mechanical and RF design engineers. (experience with design of high-power antenna array is plus)\nGeneral knowledge of circuit components used in phased array antenna systems.\nDetailed design of passive circuit components (power splitters/combiners, antenna elements, impedance transformers, etc).\nDemonstrated experience of RF engineering concepts, methodologies, and applications. \nKnowledge and experience utilizing industry-standard software tools such as Keysight ADS and Genesys, CST, Ansys HFSS, and Icepack. \nExperience utilizing MATLAB for the processing of measured and simulation results including but not limited to frequency response and time-domain processing.\nExperience in lab equipment including Network Analyzers, Spectrum Analyzers, Signal Generators, and Power Meters.\nPerform technical writing which may include proposals, reports, test procedures, and specifications.\nSelf-Motivated to Learn; Go-Getter Personality\nSpecial Consideration will be given to those with experience in high-power microwave electronics, equipment, measurement, and system design.\nIn a nutshell, we offer:\nOpportunity to sink your teeth into cutting edge industrial robotics problems\nOpportunity to contribute to the mission of transforming how we mine on Earth today and how we will one day mine on the Moon, asteroids & Mars\nCompetitive package\nBenefits: Medical, Dental, Vision \nOffer to join the OffWorld team full-time--if- You are as crazy-excited about the mission as we are.\n- You have demonstrated that you have some of The Right Stuff for this mission. \n\nOffWorld is proud to be an equal opportunity employer.","description_format":"text","description_chars":3214,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Natural Resources","Robotics","Mining Tech"],"lifecycle":[{"event":"open","at":"2026-09-05T11:44:29Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"Filed H-1B visas in the last two years","filings_12m":0,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.608,"p_room":0.55,"age_days":49,"expected_fill_days":36,"reasons":["conf:5","win:tail"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/offworld-senior-rfantenna-engineer-offworld","json_url":"https://alion.io/job/offworld-senior-rfantenna-engineer-offworld.json","meta":{"generated_at":"2026-10-26T00:49:22Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":935,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":25125},"rest":"https://alion.io/mcp/rest/get_company?id=25125"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Foffworld-senior-rfantenna-engineer-offworld"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Foffworld-senior-rfantenna-engineer-offworld"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Foffworld-senior-rfantenna-engineer-offworld"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/offworld-senior-rfantenna-engineer-offworld\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Foffworld-senior-rfantenna-engineer-offworld"}]}
