Sonic Summary

info
  • We are seeking a Staff Firmware Engineer with experience in embedded C/C++ and hardware-adjacent debugging to join our R&D team focused on developing a next-generation IoT product.
  • The role requires an individual contributor who will support firmware execution, collaborate with senior engineers, and grow into broader firmware ownership on future product lines.
  • Candidates should have a strong background in state-pattern FSM, HAL/driver architecture for MCU-based products, and familiarity with RTOS and low-power connectivity solutions.
  • The position offers a salary in the range of $120,000 to $150,000 per year, depending on experience and qualifications.
  • A minimum of 5 years of relevant experience in embedded firmware development is required for this role.

Description

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
  • Peer mentoring; improving existing codebases without destabilizing delivery
