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.\nAbout the Role \nWe are looking for a hands-on Senior Mixed-Signal Post-Silicon Validation Engineer to bring up and characterize complex mixed-signal SoCs from first silicon through product integration. \nYou will work closely with analog/mixed-signal designers, systems/DSP, firmware, FPGA, digital, and hardware teams to validate silicon performance, debug issues, and build our test and validation capability from the ground up.\nResponsibilities \nBring up and characterize mixed-signal silicon, including ADCs, DACs, PLLs, clocking, references, power, and analog signal paths. \nDevelop and execute characterization plans across frequency, voltage, temperature, process, and operating modes. \nMeasure key converter and analog performance including SNDR, SFDR, ENOB, INL/DNL, noise, bandwidth, jitter, phase noise, linearity, and power. \nDevelop automated test setups for characterization, regression, data collection, analysis, and reporting. \nWork closely with analog/mixed-signal designers to correlate silicon measurements with simulations and identify performance gaps. \nPartner with systems/DSP teams to validate DSP and calibration algorithms on silicon and correlate results with system models. \nDebug complex issues spanning silicon, firmware, package, PCB, test setup, and system behavior. \nSupport the transition from chip-level validation to product integration and system-level testing. \nContribute to building the validation lab, test infrastructure, measurement methodology, and automation from the ground up. \nDocument characterization results, silicon limitations, workarounds, and lessons learned for future silicon generations. \nQualifications \nBS/MS in Electrical Engineering or related field. \n5+ years of mixed-signal silicon validation, characterization, product engineering, or related experience. \nStrong understanding of ADC, DAC, PLL, clocking, and analog circuit fundamentals. \nDeep hands-on experience with lab test equipment such as high-speed oscilloscopes, spectrum/signal analyzers, vector signal generators, phase-noise analyzers, network analyzers, power supplies, and related mixed-signal instrumentation. \nExperience developing automated characterization environments using Python or similar scripting languages and instrument-control interfaces. \nStrong understanding of signal integrity, noise, clock jitter, spectral analysis, and mixed-signal measurement techniques. \nStrong debugging skills and ability to isolate issues across chip, package, PCB, firmware, and test environments. \nExperience working closely with IC designers and systems engineers to correlate measurements with simulations and models. \nAbility to operate effectively in a fast-moving environment and build test capability from the ground up. \nPreferred Qualifications \nRF/mmWave mixed-signal SoC experience. \nExperience with high-speed or RF-sampling ADCs and DACs. \nExperience validating digitally assisted analog circuits and calibration algorithms. \nFamiliarity with JESD204 or other high-speed converter interfaces. \nExperience with automated PVT characterization and large-scale measurement data analysis. \nFamiliarity with FPGA-based test platforms and embedded firmware. \nSI/PI, package, high-speed PCB, and RF measurement experience. \nCompensation and Benefits: \nBase salary range for this role is $170,000 - $250,000 + 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":6447,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":["Equity","Life insurance","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-22T01:25:11Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.859,"p_room":0.9,"age_days":53,"expected_fill_days":82,"reasons":["conf:2","velocity","win:mid","comp:brand"],"computed_at":"2026-11-14T05:58:10Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/k2-space-senior-mixed-signal-post-silicon-validation-engineer","json_url":"https://alion.io/job/k2-space-senior-mixed-signal-post-silicon-validation-engineer.json","meta":{"generated_at":"2026-11-15T03:12:39Z","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":5972,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-16T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":171840},"rest":"https://alion.io/mcp/rest/get_company?id=171840"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fk2-space-senior-mixed-signal-post-silicon-validation-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fk2-space-senior-mixed-signal-post-silicon-validation-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fk2-space-senior-mixed-signal-post-silicon-validation-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/k2-space-senior-mixed-signal-post-silicon-validation-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fk2-space-senior-mixed-signal-post-silicon-validation-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1102730}},{"tool":"search_jobs","arguments":{"company":"k2space.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1102730},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
