Embedded Firmware Engineer

About PigRun Solutions

PigRun Solutions designs and manufactures rugged industrial IoT tracking systems used in the oil & gas industry to monitor pipeline inspection tools (PIGs). Our products integrate embedded firmware, precision sensor acquisition, Bluetooth, cellular and satellite communications, and cloud-based dashboards.

We develop real-world hardware deployed in demanding field environments across North America.

We are looking for a Senior Embedded Firmware Engineer who can take technical ownership of firmware architecture and system-level design across our product lines.

Role Overview

This is a senior-level engineering position for someone who can:

• Architect and own embedded firmware systems end-to-end
• Lead hardware bring-up and firmware-hardware integration
• Design robust, real-time embedded systems
• Improve reliability, performance, and power efficiency
• Support deployed devices in real industrial environments

Candidates must be located in Brockville or willing to relocate.

Key Responsibilities

• Architect, develop, and maintain embedded firmware for STM32 and Nordic (nRF) platforms
• Design and implement real-time systems using FreeRTOS
• Develop robust driver-level firmware and hardware abstraction layers
• Optimize power consumption for battery-operated IoT devices
• Integrate and debug communication interfaces including Bluetooth (BLE), UART, USB, CAN, RS-485, I2C, SPI ...
• Integrate and manage cellular and satellite modem communication (LTE, NB-IoT, Iridium or similar)
• Implement secure firmware upgrade mechanisms (serial, BLE, OTA)
• Design bootloaders and firmware partitioning strategies
• Implement SD card and flash data logging systems with power-loss resilience
• Review schematics and collaborate on PCB design and hardware revisions
• Diagnose field issues and implement system-level fault recovery strategies
• Work closely with backend and dashboard teams to ensure reliable IoT data flow
• Contribute to architecture decisions for next-generation products

Required Experience & Technical Expertise

• 3+ years of professional embedded firmware development experience
• Strong expertise with STM32 microcontrollers
• Experience with Nordic nRF platforms
• Strong proficiency in Embedded C/C++
• Experience developing systems using FreeRTOS or similar real-time operating systems
• Deep understanding of MCU peripherals including:
• Timers (input capture, PWM, precision timing)
• DMA-based data pipelines
• ADC acquisition systems
• Interrupt-driven architectures
• RTC and time synchronization
• Watchdog systems
• Low-power modes and sleep states
• Experience implementing:
• SD card / FATFS data logging
• External Flash / QSPI memory management
• Bootloaders and firmware update systems
• Experience integrating:
• Bluetooth (BLE stacks)
• Cellular modems
• Satellite communication modules
• Experience debugging hardware using oscilloscopes, logic analyzers, and lab equipment
• Ability to read schematics and support PCB bring-up
• Experience working on production-ready IoT or industrial products

Strongly Preferred

• Experience building ruggedized or battery-powered industrial devices
• Experience with signal processing fundamentals (filtering, sampling, noise mitigation)
• Experience implementing fault-tolerant firmware architectures
• Experience with secure boot or firmware validation
• Exposure to Android or iOS app development
• Exposure to backend or cloud IoT systems
• Experience supporting deployed devices in the field

What We’re Looking For

We are looking for someone who can:

• Take ownership of firmware architecture
• Improve system robustness and reduce field failures
• Design for reliability, power efficiency, and scalability
• Think beyond code and understand the complete hardware + firmware + communication stack
• Work independently in a fast-moving, entrepreneurial startup environment and adapt to evolving priorities

This role is ideal for someone who enjoys building real industrial hardware — not just writing firmware in isolation.

Why Join PigRun Solutions

• Work on cutting-edge industrial IoT tracking systems
• Direct impact on product architecture and roadmap
• Small, high-impact engineering team
• Opportunity to grow into technical leadership
