We're focused on an ambitious goal to make generalized robots broadly accessible, enabling households to take back quality time.\nWe have spent the last 18 months building a talented team, securing capital, and validating our technology. We are now seeking passionate individuals to join us in the next phase of our growth. If you are ready to apply your skills to the forefront of robotics innovation, we’d love to hear from you.\nWhat to Expect\nYou will be one of the early members of the EE & Firmware team, which develops embedded software for our home robot and our wearable. This includes sensing, networking, motor control, power distribution, and more.\nAs a Firmware Engineer, you will work on robust, high-performance firmware across the entire home robot. You’ll get the chance to own multiple new boards from the initial hardware design phase, take them through board bring-up with the EE team, and integrate them into the robot. This will also include generalist work beyond firmware: motor control, systems software, and embedded Linux. In doing this, you’ll collaborate closely with the electrical, mechanical, software, controls, and machine learning teams to solve complex problems across hardware and software boundaries.\nWhat You'll Do\nOwn firmware end-to-end across our wearable and robot, from architecture and implementation through integration and production\n\nWrite high-performance host-side systems software serving as the interface layer between firmware and higher-level software\n\nDevelop robust communications, OTA, and diagnostics infrastructure for embedded devices\n\nWork with the EE team to design and bring up new hardware\n\nSolve difficult cross-functional problems spanning hardware, firmware, embedded Linux, and higher-level software\n\nWhat You'll Bring\nBS or MS degree in Computer Engineering, Electrical Engineering, a related technical field, or equivalent practical experience\n\n3+ years of real-time embedded software development, with experience in areas such as architecture design, MCU selection, driver development, and working with RTOSes\n\nProficiency in an embedded systems programming language, such as C, C++, or Rust\n\nExperience with debugging, instrumentation, and performance optimization across hardware, firmware, and host-side systems software\n\nExperience working with electrical engineering teams, with the ability to read and understand board schematics and layouts\n\nExperience with communication protocols such as I2C, SPI, UART, CAN (FD), or Ethernet\n\nNice to Have\nDelivered at least one project from prototype through mass production\n\nExperience building robust, failure-tolerant firmware OTA pipelines\n\nExperience with Ethernet firmware and communications protocol design, especially involving PTP-based time synchronization\n\nExperience with embedded Linux, build systems (Bazel, CMake), or multi-device system architecture\n\nFamiliarity with common control techniques for robot actuators, including cascaded feedback control, PID tuning, and torque control\n\nExperience with HIL testing, production validation software, or fleet-wide hardware observability\n\nExperience developing or porting platform firmware, including coreboot, UEFI/BIOS, secure boot, or TPM integration\n\nAt Sunday Robotics, we’re building technology shaped by real people - curious, creative, and diverse. We’re proud to be an equal opportunity employer and consider all qualified applicants regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.\nEven if you don’t meet every single requirement, we encourage you to apply. Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria - we don’t want that to be the reason we miss out on great talent.","description_format":"text","description_chars":3962,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-03-30T17:20:16Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.172,"p_room":0.28,"age_days":200,"expected_fill_days":30,"reasons":["conf:0","stale_co","velocity","ghost","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/sunday-firmware-engineer","json_url":"https://alion.io/job/sunday-firmware-engineer.json","meta":{"generated_at":"2026-10-17T19:37:34Z","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":2994,"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":50762},"rest":"https://alion.io/mcp/rest/get_company?id=50762"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsunday-firmware-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%2Fsunday-firmware-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%2Fsunday-firmware-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/sunday-firmware-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsunday-firmware-engineer"}]}
