Senior Test Automation Engineer jobs

There’s a new space race on and Square Peg Communications (SPCI) is ready to help its customers win it. For more than 30 years, Square Peg has developed and manufactured ground, airborne, and space-borne satellite communications products for customers worldwide, including the industry-leading RLS-2100 Radio Link Simulator, satellite terminal qualification equipment, satellite modems, and earth stations.

We are expanding our team in Ottawa, Canada, to support exciting new opportunities driven by the rapid growth of satellite-enabled communications, including broadband satellite internet access and machine-to-machine communications.

Testing is a core part of our product development process, and we are looking for a Software Development Engineer in Test (SDET) / Test Automation Engineer to help validate and improve our products. In this role, you will design and implement automated test frameworks, develop test scripts, and perform system-level testing to verify the functionality and performance of our satellite communications platforms.

The successful candidate will work closely with software, hardware, and systems engineers to develop automated tests, investigate issues, and ensure product quality before each release. This role combines hands-on testing, automation development, and system-level debugging, and is ideal for someone who enjoys working at the intersection of software, hardware, and communication systems.

You will contribute to building robust automated test suites, executing release validation tests, and improving the testing infrastructure used both internally and by customers working with our products.

Test Automation

• Develop and maintain Python-based automation scripts and test frameworks used for system validation.
• Design new test scenarios and edge case validations based on product requirements.
• Improve test coverage and testing workflows over time.
• Automate repetitive test scenarios to increase coverage and reduce manual testing effort.
• Implement tools for automated test execution, logging, and reporting.

Product Testing & Release Validation

• Plan and execute test cycles for each release of SPCI products.
• Develop and maintain test plans, test cases, and validation procedures for new features and system updates.
• Perform manual and automated testing to verify system functionality, performance, and reliability.
• Execute regression test suites prior to product releases to ensure new changes do not impact existing functionality.
• Document test results, defects, and verification status and work with engineering teams to track and resolve issues.
• Verify bug fixes and ensure issues are fully resolved before release approval.
• Investigate test failures, unexpected behavior, and system anomalies.
• Analyze test results, logs, and telemetry data to identify potential issues.
• Work closely with developers to reproduce issues and validate fixes.

Collaboration

• Work closely with software engineers, system engineers, and hardware engineers to understand system behavior and testing requirements.
• Participate in release planning and engineering discussions.
• Contribute to continuous improvements in testing processes, automation coverage, and product quality.

Qualifications

Education

Bachelor’s Degree or higher in one of the following or equivalent:

• Computer Science
• Computer Engineering
• Electrical Engineering

Experience

• 3-5 years of experience in test automation, system testing, or test tools development.
• Strong Python programming skills, including writing clean, maintainable, and well-structured code.
• Experience using Python testing frameworks such as pytest, unittest, or similar frameworks.
• Experience developing and maintaining automated test suites for complex systems.
• Experience testing embedded systems or hardware-integrated software.
• Experience interacting with hardware devices or embedded systems during testing (e.g., serial interfaces, network-connected devices, or test equipment).
• Good understanding of embedded system concepts, including firmware interaction, device interfaces, and system-level debugging.
• Experience using Git for version control, including working with branches, pull requests, and collaborative workflows.
• Strong debugging, troubleshooting, and analytical problem-solving skills.
• Experience using hardware debugging tools such as oscilloscopes, multimeters, signal generators, power meters, or spectrum analyzers.

Even Better, You May Have

• Experience working with hardware test setups or laboratory environments.
• Experience with continuous integration systems such as Jenkins or GitLab CI.
• Experience building or contributing to test automation frameworks or infrastructure.
• Familiarity with network protocols and network-based systems, with the ability to debug and analyze communication between components.
• Familiarity with digital communications techniques for satellite and other wireless systems.

Ideal Candidate

The ideal candidate is someone who enjoys working where software meets hardware and likes digging into complex systems to understand how things work. You’re comfortable troubleshooting issues that span across multiple components, whether that’s software, hardware, or the interaction between them.

You have solid automation and scripting skills, and you’re always looking for ways to improve testing efficiency through better tools and automation. You’re also self-motivated, curious, and collaborative, and enjoy working closely with engineers from different disciplines to solve problems and improve the product.

If you would like to work on diverse projects with a team of skilled professionals to realize best-in-class communications product technologies and industry-leading test systems, please apply referencing this posting and citing specific examples of your relevant qualifications. Only selected candidates will be contacted. Thank you for your interest.
