Staff / Firmware Engineer

Staff/Lead Firmware Engineer Austin, Tx (Onsite) Direct Hire (Full time), US and GC only Salary 160k + Benefits Client: Oil & Gas Domain We are hiring a Staff Firmware Engineer to add senior embedded firmware capacity and deep technical contribution on a small R&D team as we deliver a flagship next-generation IoT product and prepare follow-on platform work. This is an individual contributor role. There is no expectation to manage people or lead a firmware team. This person will: Support current-program firmware execution: state-pattern FSM, HAL boundaries, driver integration, prototype board bring-up, and firmware-test readiness. Partner with the existing senior firmware engineer (program DRI) on near-term delivery; the current DRI remains accountable while this person ramps. Work with a senior firmware architecture advisor on platform standards, architecture review, release hygiene, and cross-team consistency. Grow into broader firmware ownership on follow-on product lines once the current foundation is stable — as a senior IC, not as a people manager. Bring disciplined embedded execution: Jira stories, design notes / ADRs, code reviews, tests, and early escalation. Requirements Embedded C/C++, HW-adjacent debug, shipped product, test discipline, collaboration State-pattern FSM, hierarchical state machines, event-driven architecture, embedded UI/menu systems HAL / driver architecture for MCU-based products RTOS, watchdogs, bootloaders, firmware update, low-power, BLE/USB/serial Radio / connectivity (big plus): GPS/GNSS, BLE, cellular modem, satellite modem, RF module integration Analog measurement (big plus): ADC, calibration, noise/drift, accuracy, data acquisition, DVM/instrumentation Safety/reliability: logging, fault handling, recovery, release hygiene Test automation, hardware-in-loop, unit tests, CI for embedded Test & measurement, industrial instrumentation, power electronics, field equipment Saxon Global
