Managing a complex architecture that integrates third-party hardware with our autonomous vehicle platform, you will analyze diagnostics and log outputs across cellular networks, 4G/5G modems, internal software layers, Wi-Fi, and Bluetooth. You will not only reactively troubleshoot complex field issues but also proactively architect and develop robust host-side connectivity software to handle cellular edge cases and vulnerabilities before they impact operations.\nYour work will directly safeguard the safety, reliability, and scaling of the Zoox autonomous fleet. Robust, low-latency connectivity is fundamental to autonomous vehicle deployment, powering essential real-time cloud services, fleet management pipelines, and teleoperation capabilities. By ensuring our vehicles maintain seamless, high-performance connections under the most demanding real-world conditions, you will bridge the gap between cutting-edge hardware, cloud infrastructure, and test systems to enable Zoox to deliver the future of autonomous mobility.\nYou will leverage a profound understanding of how these stacks operate to define the architecture, utilize vendor interfaces, and debug complex cross-layer issues.\nResponsibilities\nContribute and Develop: Contribute to Zoox's firmware and cellular wireless connectivity stack (LTE/5G), developing and enhancing connectivity features across multiple generations of hardware.\n\nVendor Integration: Act as the primary technical expert working with cellular chipset vendors (e.g., Qualcomm) to integrate their proprietary firmware, SW stacks, and L1-L3 implementations into our custom embedded Linux platform.\n\nArchitecture Definition: Define, architect, and validate the critical software interfaces between the RF-baseband, the vendor's protocol stack (AP), and our host system, writing the host-side glue code (C/C++) needed for the Linux networking stack.\n\nPrototyping: Prototype and evaluate next-generation wireless platforms for future Zoox products.\n\nTelemetry and Analytics: Develop the telemetry and analytics platform enabling data collection, analysis, and visualization of data reported from the Zoox fleet.\n\nInvestigate and Solve: Investigate and root-cause issues reported by QA teams and customer feedback. Differentiate between host-side bugs and vendor firmware issues using your deep knowledge of cellular protocols.\n\nQuality and Automation: Support test automation frameworks, collaborate with QA, manufacturing, and other software teams, and drive continuous improvements and best practices within the broader organization.\n\nQualifications\nMore than 10+ years of experience in embedded linux systems and cellular/wireless stack software/firmware development.\n\nB.S. or M.S. degree in Computer Engineering, Computer Science, Physics, Electrical Engineering, or equivalent experience.\n\nExceptional programming skills in C/C++, Linux OS, and Python/Shell scripting.\n\nDeep architectural understanding of LTE/5G Protocol Stacks (NAS, PDCP, RRC, RLC, MAC, PHY) and 3GPP specifications.\n\nProven experience successfully integrating third-party cellular modems and proprietary stacks, with hands-on experience using Qualcomm ecosystems and cellular network analysis tools (e.g., QXDM, Shannon Tools, Wireshark).\n\nGood understanding of Embedded Systems, OS concepts, computer architecture, data structures, and algorithms.\n\nHands-on experience in maintaining the Linux Applications, kernel code and embedded services, including experience porting and patching open-source packages within the Yocto Project environment.\n\nStrong understanding of networking concepts (Ethernet, TCP/IP, IP routing design, VLANs, firewalls, and both IPv4 and IPv6 protocols).\n\nBonus Qualifications\nWorking experience in the Automotive industry.\n\nFamiliarity with other wireless technologies (Wi-Fi, Bluetooth, BLE).\n\nFamiliarity with embedded interfaces (UART, I2C, I2S, SPI, CAN, PCIe, etc.).\n\nPrior experience collaborating with test teams using industry-standard network emulation tools (e.g., Keysight UXM).\n\nExperience in design, develop, and secure wireless software systems by implementing robust network protocols and advanced wireless security protocols.\n\nHighly motivated and self-directed. Thrives in a collaborative environment and can clearly communicate complex technical issues to both internal teams and external vendors.","description_format":"text","description_chars":4514,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Autonomous Driving","Smart Mobility","Automotive Manufacturing","Ride Hailing"],"lifecycle":[{"event":"open","at":"2026-08-26T20:04:06Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 373 · green card filings: 120","filings_12m":373,"filings_prev_12m":311,"green_card_filings_12m":120,"median_offered_wage_usd":181283,"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)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":17}],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":1,"p_active":0.582,"p_room":0.9,"age_days":51,"expected_fill_days":85,"reasons":["conf:1","stale_co","velocity","win:mid","comp:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":265000,"is_top_pay":true},"html_url":"https://alion.io/job/zoox-software-engineer-wireless-technologies","json_url":"https://alion.io/job/zoox-software-engineer-wireless-technologies.json","meta":{"generated_at":"2026-10-17T11:06:24Z","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":14480,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":3626},"rest":"https://alion.io/mcp/rest/get_company?id=3626"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzoox-software-engineer-wireless-technologies"},{"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%2Fzoox-software-engineer-wireless-technologies"},{"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%2Fzoox-software-engineer-wireless-technologies"},{"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/zoox-software-engineer-wireless-technologies\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzoox-software-engineer-wireless-technologies"}]}
