Job Description

Q-Block Computing is seeking a Senior Embedded Software Developer to join our growing team in Ottawa, Ontario. This role offers an exciting opportunity to contribute to the development of cutting-edge quantum technologies in sensing, communication, and computation. The candidate will join Q-Block Computing to serve as the lead firmware developer on the Qubit Composer platform team, delivering complex subsystems and coordinating the day-to-day development work of the embedded software team under the guidance of the Technical Team Lead.

Job Summary

As a Senior Embedded Software Developer on the Quantum Control Firmware team, you will collaborate with other team members and achieve technical milestones under the guidance of the Technical Team Lead. Job duties include the design, architecture, and implementation of firmware libraries and embedded control subsystems for ARM Cortex-M-based platforms. This may include applications such as real-time multi-unit synchronization, deterministic waveform generation, and high-throughput data pipelines for quantum sensing, communication, and computation hardware.

Responsibilities

  • Design, architect, and implement reusable firmware libraries and embedded control subsystems in C/C++ for ARM Cortex-M platforms within the Arduino/PlatformIO ecosystem
  • Analyze system-level requirements and recommend architectural approaches for new firmware features and subsystem modifications
  • Develop and validate DMA-based parallel data transfer subsystems and synchronous multi-pin I/O operations for deterministic, low-latency hardware control
  • Implement and test high-speed peripheral control for DAC, ADC, DDS, PLL, digital potentiometers, and RF attenuator/amplifier ICs communicating over SPI and LVDS
  • Design and implement digital control loop modules (PI2D, FIR/IIR filters) for precision analog output stabilization
  • Coordinate task execution and review the code, test results, and documentation of Electronics Engineering Technologists and other developers on the team
  • Conduct system-level integration testing across multiple interconnected control units; design test strategies and document integration procedures and failure modes
  • Set up and maintain firmware build environments, toolchains (PlatformIO, Make), and Git workflows for the team
  • Write documentation for new and updated firmware subsystems
  • Collaborate with cross-functional hardware and quantum systems teams
  • Contribute to a culture of continuous learning and knowledge sharing within the team

Qualification

  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field
  • 5+ years of professional experience in embedded software development with ARM Cortex-M or comparable architectures

Skills

  • Strong C/C++ proficiency; demonstrated experience designing reusable embedded libraries or firmware architectures
  • Deep understanding of DMA configuration, memory-mapped I/O, and real-time scheduling on ARM microcontrollers
  • Experience with high-speed SPI, multi-IC board-level integration, and mixed-signal debugging
  • Demonstrated ability to coordinate and review the technical work of other developers
  • Experience with NXP i.MX RT series, Teensy, or PlatformIO platforms is an asset
  • Exposure to digital control theory (PID, IIR/FIR), precision timing systems, or clock synchronization is an asset
  • Good laboratory knowledge with electronic circuits and standard instruments such as oscilloscopes, logic analyzers, and signal generators
  • Strong attention to detail and a sense of responsibility in all tasks
  • Critical thinking and problem-solving mindset
  • Strong interpersonal skills and ability to work collaboratively in a dynamic team environment

Benefits

  • Extended health care benefits (inc. dental and vision)
  • Life insurance

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
