You will work closely with engineering teams and technology vendors to bring designs into production.\nResponsibilities\nDesign Wi-Fi RF boards around Qualcomm radio ICs, including FEMs, PAs, LNAs, filters, switches, matching networks, and supporting power and clock circuits.\nDevelop frequency-conversion circuits using synthesizers, PLLs, VCOs, mixers, and LO distribution. Evaluate phase noise, spurious signals, image rejection, and isolation.\nCreate and maintain schematics in OrCAD Capture, select components, and prepare BOMs. Guide PCB layout and review stack-up, RF routing, controlled impedance, grounding, shielding, and decoupling.\nBring up, tune, and characterize Wi-Fi hardware using chipset vendor tools. Configure and validate board data files (BDFs), front-end settings, TX power tables, and calibration data.\nDebug and optimize RF performance, including EVM, output power, receiver sensitivity, spectral emissions, IQ imbalance, LO leakage, and interference. Tune and validate digital predistortion (DPD), where applicable.\nDefine and execute RF verification plans across frequencies, bandwidths, modulations, RF chains, temperatures, and supply conditions, including MIMO and multi-link operation where applicable.\nDevelop automated measurement scripts, data analysis, and reporting tools for development, regression testing, and production support.\nPerform RF system analysis, including link budgets, cascaded gain and noise figure, linearity, dynamic range, filtering, and spurious products. Use circuit and EM simulations to guide design and validate results against measurements.\nCollaborate with firmware, software, mechanical, PCB layout, and manufacturing teams, as well as chipset and component vendors, to resolve integration issues and support product release.\nRequirements\nRequirements\nBSc in Electrical Engineering or a related field.\nSubstantial hands-on experience in RF hardware development, with proven ownership of complex designs from concept through validation.\nProven experience designing and bringing up Wi-Fi boards based on Qualcomm or equivalent radio ICs; direct Qualcomm experience is strongly preferred.\nHands-on experience with Wi-Fi calibration, vendor test tools, BDFs or equivalent configuration files, and RF performance debugging.\nPractical experience designing synthesizer-based frequency-conversion circuits.\nProficiency in OrCAD Capture and experience guiding and reviewing RF PCB layouts.\nStrong lab skills using spectrum and vector signal analyzers, signal generators, VNAs, power meters, oscilloscopes, and Wi-Fi test platforms such as LitePoint.\nStrong practical skills in fine-pitch soldering, rework, and board-level troubleshooting.\nExperience developing automated RF tests in Python, MATLAB, or similar tools.\nExperience with RF simulation tools such as ADS or AWR, including correlation of simulations with measured results.\nSolid understanding of Wi-Fi PHY, modulation, OFDM, MIMO, and transmitter and receiver performance metrics.\nAbility to work independently and collaborate across engineering disciplines.\nExcellent written and spoken English.\nAdvantages\nExperience with Wi-Fi 6, 6E, or 7, including multi-link operation (MLO).\nMicrowave or millimeter-wave hardware experience.\nExperience with electromagnetic simulation tools such as HFSS or CST.\nExperience with regulatory testing, including FCC and ETSI requirements.\nExperience with production calibration and transferring RF designs into manufacturing.","description_format":"text","description_chars":3921,"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":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Telecommunications","Broadband","Fixed Wireless"],"lifecycle":[{"event":"open","at":"2026-10-14T06:56:23Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.816,"p_room":0.945,"age_days":10,"expected_fill_days":27,"reasons":["conf:2","win:mid"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/radwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion","json_url":"https://alion.io/job/radwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion.json","meta":{"generated_at":"2026-10-22T13:16:04Z","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":12312,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":49208},"rest":"https://alion.io/mcp/rest/get_company?id=49208"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fradwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion"},{"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%2Fradwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion"},{"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%2Fradwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion"},{"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/radwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fradwin-senior-rf-hardware-engineer-wi-fi-and-frequency-conversion"}]}
