LECCS (Level 3 DC fast charging, CHAdeMO-adjacent), OCPP 1.6/2.0.1 for CSMS communication, ISO 15118 (PLC-based EV-EVSE communication, Plug & Charge), and IEC 61851 for AC charging control.\n\n- Maintain the telematics module: cellular (4G/LTE, NB-IoT) and Wi-Fi connectivity, MQTT/HTTPS uplinks to the cloud backend, GPS/location reporting, and remote diagnostics.\n\n- Implement secure OTA firmware update pipelines for chargers deployed in the field, including rollback and fail-safe handling.\n\n- Develop robust state machines for charging session lifecycle: authentication, authorization, energy metering, fault handling, and session termination.\n\n- Debug field issues using JTAG/SWD, logic analyzers, and CAN/PLC bus traces; work closely with hardware and power electronics teams on EMI/EMC and signal integrity issues.\n\n- Collaborate with the cloud/backend team to define telemetry data schemas, remote configuration, and fleet monitoring dashboards.\n\n- Write unit and integration tests, contribute to CI pipelines, and maintain firmware documentation and protocol compliance records.\n\n- Mentor junior firmware engineers and review code for reliability, safety, and protocol conformance.\n\n- Own firmware end-to-end for a fast-growing charging network - from silicon to cloud.\n\n- Work on one of the most protocol-rich problems in embedded systems today, spanning power electronics, networking, and telematics.\n\n- You will be working with a small, senior team with high ownership and direct impact on product reliability at scale.\n\nIdeal Candidate:\n\n- 5 to 8 years of embedded firmware development in C/C++ on microcontrollers (STM32, TI, NXP, or similar).\n\n- Hands-on experience with EV charger communication protocols: LECCS, OCPP (1.6/2.0.1), ISO 15118, IEC 61851, and familiarity with CHAdeMO/CCS/GB/T charging standards.\n\n- Strong understanding of CAN, Modbus, RS-485, and PLC (Power Line Communication, e.g. HomePlug Green PHY / QCA7000) for EV-EVSE communication.\n\n- Experience building telematics/connectivity firmware: cellular modem integration (Quectel/SIMCom/u-blox), MQTT/HTTPS/TLS, GPS, and remote monitoring or fleet-management systems.\n\n- Solid grasp of RTOS concepts (FreeRTOS or similar) and real-time, safety-critical firmware design.\n\n- Familiarity with power electronics interfacing - metering ICs, relay/contactor control, ground fault detection (GFCI), and charger safety interlocks is a strong plus.\n\n- Comfortable with debugging tools (JTAG/SWD, oscilloscope, CAN/PLC analyzers) and root-causing field failures.\n\n- Working knowledge of relevant safety and compliance standards (IEC 61851, IEC 61850, UL 2594/2202, or equivalent) is a plus.\n\n- Strong communication skills and experience mentoring or leading a small firmware team.\n\n- Prior experience at an EV charging OEM, CPO (charge point operator), or automotive/EVSE supplier.\n\n- Exposure to Plug & Charge / ISO 15118-2/-20 security and certificate handling.\n\n- Experience with cloud-side OCPP backend (CSMS) integration and testing.\n\n- Familiarity with functional safety practices (ISO 26262 or IEC 61508) in an embedded context.\n\nSkills\nFirmware, Charging System, Embedded System, Microcontroller, C, C++, Cloud, PLC","description_format":"text","description_chars":3373,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-25T18:04:06Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.607,"p_room":0.45,"age_days":52,"expected_fill_days":28,"reasons":["seen:52","win:tail"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/rideriver-senior-firmware-engineer","json_url":"https://alion.io/job/rideriver-senior-firmware-engineer.json","meta":{"generated_at":"2026-11-02T07:56:35Z","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":11155,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":2174120},"rest":"https://alion.io/mcp/rest/get_company?id=2174120"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frideriver-senior-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%2Frideriver-senior-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%2Frideriver-senior-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/rideriver-senior-firmware-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frideriver-senior-firmware-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1253077}},{"tool":"search_jobs","arguments":{"company":"rideriver.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1253077},"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.
