Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price - and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.\nThe rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.\nWith multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger - helping develop the solar system and build toward a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a high-growth Series D-funded company, we'd love for you to apply.\nThe Role\nYou will be responsible for the test & measurement of radiofrequency (RF) and microwave electronics to be hosted on some of the largest, most powerful, rapidly designed and rapidly manufactured satellites ever deployed in space. In your first 6 months you will develop the RF test and measurement infrastructure required to integrate and test new RF electronics and antennas for use in software defined radio (SDR) systems for satellite communications and beyond. You will work with a multidisciplinary team of antenna, RF, field programmable gate array (FPGA), digital signal processing (DSP), software, mechanical, and electrical engineers in order to prototype your systems and refine your designs. In your first two years you will have contributed to developing cutting-edge RF systems that will fly in space.\nResponsibilities\nLead research, design, and procurement of antenna measurement assets such as anechoic chambers and near field scanners\nQualify radiofrequency and antenna hardware through environmental testing including vibration, shock, thermal, and thermal vacuum (TVAC) testing\nAssist with design and validation testing for radiofrequency and microwave hardware from UHF 200 MHz through Ka band 30 GHz, including phased array antennas, low noise amplifiers, power amplifiers, filters, high speed converters, and other RF electronic components\nExecute development and production tests to meet internal and external customer needs\nCollaborate closely with internal and external stakeholders to integrate your designs into the spacecraft system\nQualifications\nBachelor’s degree in computer, electrical, aerospace engineering, or other relevant science, technology, or mathematics discipline\n2+ years of experience in microwave, RF, or antenna engineering\nExperience with RF test equipment such as vector network analyzers (VNA), spectrum analyzer, etc.\nExperience with anechoic chambers and antenna measurement assets such as near field scanners\nAbility to work in a fast-paced and high velocity start-up atmosphere\nNice to Have\nExperience with environmental testing for space electronics such as thermal, vibration, TVAC, radiation, and EMI/EMC testing per standards such as SMC-S-016\nExperience with RF systems testing, including antenna characterization and insertion loss tests\nExperience with antenna and electromagnetic modeling and analysis software tools such as Ansys Electronics Desktop HFSS and Altair FEKO\nExperience with software defined radio hardware development including high speed RF data converters (digital to analog and analog to digital converters), clock trees, and data converter interfaces\nCompensation and Benefits:\nBase salary range for this role is $110,000 - $170,000 + equity in the company\nSalary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level\nComprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks\nIf you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!\nIf you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.\nExport Compliance\nAs defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.”\nThe person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.\nEqual Opportunity\nK2 Space is an Equal Opportunity Employer; employment with K2 Space is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.","description_format":"text","description_chars":5827,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Life insurance","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace"],"lifecycle":[{"event":"open","at":"2026-10-08T09:30:49Z"}],"visa":[],"liveness":{"score":85,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.851,"p_room":1,"age_days":2,"expected_fill_days":10,"reasons":["conf:0","velocity","win:early","comp:junior,brand"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/spacenexus-rf-antenna-engineer","json_url":"https://alion.io/job/spacenexus-rf-antenna-engineer.json","meta":{"generated_at":"2026-10-11T23:36:53Z","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":14719,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"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":2086894},"rest":"https://alion.io/mcp/rest/get_company?id=2086894"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fspacenexus-rf-antenna-engineer"},{"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%2Fspacenexus-rf-antenna-engineer"},{"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%2Fspacenexus-rf-antenna-engineer"},{"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/spacenexus-rf-antenna-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fspacenexus-rf-antenna-engineer"}]}
