Our mission? Develop cutting-edge technology to revolutionize what it means to be a pet parent. The pet industry remains firmly stuck in the past and we are here to change that. Fi is leveraging our team's talent and expertise to improve the lives of millions of pets in the U.S. Real-time location tracking, activity, sleep and behavior monitoring - and that's just the beginning.\nThe most exciting aspect of our work? Bridging the communication gap between pets and humans. Imagine a world where everyone knows how their pet feels in real time and how to keep their best friend in good shape. That's the future we're building at Fi.\nIf you're someone who thrives in innovative, collaborative work environments and feels strongly about helping pets live longer, better lives, Fi could be the perfect fit. Join us in our pursuit of the “impossible,” or as we call it here “let me find a way,” to redefine the future of pet ownership together.\nFi is looking for an Antenna Engineer!\nFi is looking for an Antenna Engineer to own antenna design end-to-end for our connected products, shaping how they perform in the real world, not just on paper. You’ll work from early system architecture through mass production, partnering closely with electrical, mechanical, and product teams to solve hard constraints around size, power, reliability, and manufacturability. The work spans RF design, antenna integration, tuning, and validation, and directly sets the technical foundation for Fi’s next generation of high-volume consumer hardware operating at scale.\nWhat You'll Do:\nOwn end-to-end antenna design for Fi products, from proof-of-concept through mass production.\nLead antenna architecture and contribute to overall system architecture, including RF component selection, schematic capture, and RF PCB layout.\nDesign, optimize, tune, and validate antennas to meet aggressive constraints around size, performance, reliability, and manufacturability.\nWork closely with mechanical, industrial design, firmware, leadership, and overseas engineering teams to ensure seamless antenna integration into the product.\nPush antenna performance using a mix of best practices, state-of-the-art approaches, and novel designs where needed - because every dB matters.\nPartner directly with overseas CM/JDM teams on antenna implementation, performance testing, compliance, and production ramp.\nWhat You'll Bring:\n8+ years of experience designing electrically small antennas for consumer electronics or similar products.\nBachelor’s or Master’s degree in Electrical Engineering or a related field.\nProven ability to translate product-level connectivity requirements into RF system and antenna requirements, including managing external consultants and fabrication vendors as needed.\nDeep hands-on experience with custom antenna design in the ~600 MHz to 3 GHz range, including multiband designs, polarization control, antenna isolation in close proximity, and performance optimization near human or animal tissue.\nStrong understanding of antenna integration, including use of enclosures and mechanical structures as part of the antenna system.\nExperience across common antenna fabrication methods and materials, including LDS, FPC, PCB, stamped metal, and ceramic chip antennas, with an understanding of material tradeoffs.\nComfort building scrappy prototypes using rapid methods such as hand-formed copper, milling, or 3D printing.\nProficiency with 3D electromagnetic simulation tools for antenna design.\nStrong RF lab skills, including conducted and radiated measurements, antenna tuning, and managing cable effects when testing electrically small antennas.\nExperience operating semi-anechoic chamber testing and supporting regulatory and compliance testing.\nAbility to design simple schematics and PCBs to support antenna prototyping and test.\nFamiliarity with firmware and software requirements for RF validation, including sensitivity metrics like BER and PER, and comfort using scripts (e.g., Python) for test automation or analysis.\nProven track record leading antenna designs from prototype through mass production.\nWillingness to travel to China as needed.\nWhy You'll Love Us:\nTime to Recharge: Enjoy flexible PTO to take the breaks you need.\n Top-Notch Health Coverage: We’ve got your back (and teeth and eyes) with full medical, dental, and vision insurance.\nWellness Perks: Free access to One Medical, Kindbody, and Talkspace to keep you feeling your best.\nDog-Friendly Office: Bring your pup to work - they’re part of the team, too.\nGive Back to the Pups: Make tails wag with a $500 annual donation to a dog charity of your choice through our BarkBack Program.\n Free Fi Membership: Your furry best friend(s) get all the benefits of a Fi collar, on us!\n Love for Friends + Family: Share the Fi magic with loved ones through our gifting program.","description_format":"text","description_chars":4972,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Pet Food, Supplies & Care","Smartwatches & Fitness Trackers"],"lifecycle":[{"event":"open","at":"2026-10-28T20:11:39Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":28,"reasons":["conf:3","win:early"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/fitracking-staff-antenna-rf-systems-engineer","json_url":"https://alion.io/job/fitracking-staff-antenna-rf-systems-engineer.json","meta":{"generated_at":"2026-10-31T05:32:09Z","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":7979,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":15269},"rest":"https://alion.io/mcp/rest/get_company?id=15269"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffitracking-staff-antenna-rf-systems-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%2Ffitracking-staff-antenna-rf-systems-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%2Ffitracking-staff-antenna-rf-systems-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/fitracking-staff-antenna-rf-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffitracking-staff-antenna-rf-systems-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3418212}},{"tool":"search_jobs","arguments":{"company":"fitracking.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3418212},"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.
