Embedded System Developer Jobs in Ontario (NOW HIRING)

About Voyis 

Voyis designs and manufactures high performance underwater optical sensors (lasers, cameras, lights)for underwater vehicles that expand capability and enhance understanding in underwater surveys and exploration. Our products have enabled our customers to survey more than 10,000km of ocean floor across all 7 continents, helping people better understand those remote, challenging environments.  

Our mission is to push the limits of what’s possible subsea and enable every underwater vehicle to see the depths like we see the surface. All our products are proudly designed and built in Waterloo.  

The Role 

As an Embedded Systems Test Engineer at Voyis, you will play a critical role in improving how we automate, test, validate, and release the software that powers our underwater camera and laser systems. 

You will drive and own quality across the full Voyis stack by validating entire systems including embedded compute, real-time sensor hardware and backend services – all with a focus on building test automation. The role is heavily focused on integration level testing and ensuring release reliability across the range of SW/FW/HW configurations in our core products. You will also contribute to validating utility libraries and internal tools that support both software development and production operations, including calibration, data management, and device maintenance.  

Experience & Core Competencies 

• 6+ years of experience in test automation, embedded systems validation, and systems integration testing in safety-critical or hardware-centric product environments (e.g., automotive, industrial, robotics, sensors)

• Hands-on experience validating individual hardware subsystems — imaging sensors, storage devices, and network interfaces — including defining acceptance criteria and test coverage at the component level

• Advanced working knowledge of embedded Linux — comfortable navigating the kernel/userspace boundary, configuring device tree overlays, managing kernel modules and drivers, and debugging peripheral enumeration issues (e.g., via dmesg, sysfs, udev)

• Advanced embedded systems background: firmware on ARM Cortex platforms, peripheral-level debugging, and board bring-up — able to test at the level the firmware is written

• Experience testing high-bandwidth data paths, including Ethernet throughput/latency validation, packet loss analysis, and protocol-level debugging (e.g., using Wireshark or similar tools)

• Familiarity with storage subsystem validation — sustained write performance, data integrity under power interruption, endurance testing, and filesystem-level fault handling

• Working knowledge of common embedded interfaces and buses (MIPI CSI, SPI, I2C, UART, GigE) and the tools to exercise and instrument them

WhatYou’llDo 

• Own the end-to-end test strategy for Voyis products — defining and implementing manual and automated approaches spanning functional, regression, integration, performance, fault-injection, and compatibility testing
• Architect, build, and continuously improve HIL test environments that validate software and firmware directly on physical sensors and embedded systems
• Develop monitoring and observability services to track mission-critical metrics — system latency, data throughput, data integrity — ensuring high-fidelity real-time visualization and sensor accuracy
• Lead root cause analysis on escaped defects using structured techniques, reproduce issues in controlled test environments, and strengthen automated coverage to prevent recurrence
• Mentor and develop junior QA engineers
• Champion a quality-first engineering culture, partnering with firmware, software, and hardware teams to shift testing left and build testability into designs from the start 

Nice to Have 

• Strong development skills in C/C++, and scripting languages such as Python, disciplined use of git, and professional software development standards

• Experience designing and maintaining CI/CD-integrated firmware and software regression pipelines (GitLab), including structured test case libraries, pass/fail criteria, coverage tracking, and reporting dashboards (Prometheus, Grafana)

• Experience setting up and managing self-hosted runners and platform matrix builds (Linux x64/arm64, Windows)

• Experience with containerization and orchestration (Docker,Buildah)

• Experience with infrastructure as code (Ansible, etc.)including playbooks, roles, and automation workflows

• Hands-on hardware testing experience with some debugging knowledge using an oscilloscope or multimeter

• Comfortable with Linux and/or Windows systems administration and debugging infrastructure issues

• Willing to learn about sensor characterization and calibration verification (e.g., image quality metrics, timestamp synchronization, etc)

Work Location 

This is primarily an in-person role based at our Waterloo headquarters. Some flexibility for remote work is available; however, fully in person is preferred and a minimum of four days on-site is expected to support close collaboration with the team who is nearly full time in office. 

The Perks 

• 5 weeks of total time off, flexible work hours and a dedication to a work-life balance.
• Employee-directed personal education funds to drive continuous learning
• Profit-sharing within to celebrate our successes together
• Regular company-wide social events
• Health and vision benefits
• RRSP Matching 

The Pay 

This opening is for an active vacancy. The salary range for this role is $95,000 to $130,000 dependent on skillset and experience.
