The engineer will own end-to-end platform software development-spanning Board Support Packages (BSP), network operating systems (SONiC, FBOSS), baseboard management controller firmware (OpenBMC), and hardware diagnostic software for both platform-level and ASIC-level validation. The ideal candidate combines deep embedded systems expertise with systems-level thinking, bridging hardware and software to deliver production-grade infrastructure at scale.\nThis role spans both x86 and ARM architectures and demands fluency across the full stack-from low-level firmware and device drivers to user-space services, telemetry frameworks, and diagnostic tooling.\nResponsibility\nPlatform software Design and Development: Architect and develop Linux BSP, platform drivers, and user-space services for SONiC (x86), FBOSS (x86), and OpenBMC (ARM) platforms-covering kernel/device-tree configuration, bootloader integration, DMTF-based manageability (MCTP, PLDM, Redfish), and peripheral drivers (I2C, SPI, PCIe, GPIO). Design embedded diagnostic firmware in C/C++ for hardware bring-up, manufacturing validation, and health monitoring. Develop ASIC-level tests (memory, SerDes, datapath) and platform-level diagnostic suites (PCIe, power rail, thermal, transceiver), integrating diagnostics into manufacturing flows and field RMA processes. Contribute to relevant open-source communities.\nSystem Performance Analysis and Troubleshooting: Use structured debug methodologies and hardware tools (JTAG, logic analyzers) to isolate hardware vs. software failures and drive root-cause resolution. Profile and optimize platform software for boot time, latency, and resource utilization.\nHardware and Software Testing and Validation: Plan and execute HW/SW validation campaigns with defined pass/fail criteria. Build automated test infrastructure in Python and Bash for orchestration, log parsing, and CI/CD integration. Instrument code for coverage and maintain quality metrics.\nDiagnostic Tools and Methodologies Development: Build scripts and utilities (Python, Bash) for faster debug, capture, and repeatable runs; standardize trace/result workflows; and hook into validation pipelines and internal tooling as programs scale.\nCollaboration with Cross-Functional Teams: Partner with hardware, firmware/software, validation, and program teams on priorities, joint debug, and evolving diagnostic coverage for production-quality outcomes.\nOwnership of Code Quality, Performance, and Reliability: Deliver maintainable code with solid tests, reviews, and engineering practice so platform,diagnostic firmware and related software meet performance and production standards.\nQualifications\nStrong analysis and hands-on troubleshooting on complex HW/SW systems.\nProven testing and validation of hardware and software for performance and reliability.\nStrong proficiency in C/C++ for embedded and systems-level development; Python and Bash for automation, scripting, and tooling\nEE background: circuit design and system integration.\nClear written and verbal communication across disciplines.\nStrong understanding of hardware interfaces and protocols: I2C, SPI, PCIe, UART, GPIO, MDIO, JTAG. Diagnostic tools and methodologies (plus).\nBachelor’s or higher in Electrical Engineering, Computer Engineering, or a related field.\n10+ years in platform, diagnostic embedded firmware development.","description_format":"text","description_chars":3478,"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":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-01T21:40:16Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 35","filings_12m":35,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":222500,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":9}],"liveness":{"score":43,"band":"fade","label":"Fading","p_open":1,"p_active":0.776,"p_room":0.55,"age_days":52,"expected_fill_days":51,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-04T05:45:00Z"},"pay":{"stated_usd_annual":260000,"is_top_pay":false},"html_url":"https://alion.io/job/upscale-ai-senior-staff-engineer-platform","json_url":"https://alion.io/job/upscale-ai-senior-staff-engineer-platform.json","meta":{"generated_at":"2026-10-05T01:41:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2263,"day_limit":5000,"remaining_today":2737,"minute_limit":60,"resets_at":"2026-10-06T00:00:00Z"}}}
