About Sienci Labs

At Sienci Labs, we build software that empowers people to create, collaborate, and innovate. Our tools are used by a growing community of developers, businesses, and creators around the world. We're a small, fast-moving team that thrives on solving real-world problems through clean code, smart engineering, and a relentless focus on quality.

About the Role

We're looking for a sharp, detail-oriented QA Analyst who brings hands-on CNC experience to the table. This role is not just about testing code—it's about being the bridge between our software development team and other departments (customer support, product, manufacturing, sales, etc.).

You will proactively reach out to these teams to uncover bugs, understand how our software behaves in real CNC workflows, and ensure issues are caught early and communicated clearly. If you understand how CNC machines operate, how operators think, and how software can break in the real world, we want to talk to you.

What You'll Be Doing

  • Act as a liaison between the software development team and other departments (support, product, manufacturing, sales) to identify, prioritize, and document software bugs.
  • Proactively communicate with non-technical teams to gather real-world bug reports and usage feedback.
  • Write and maintain unit tests and automated test suites for our Electron, React, Node.js, and TypeScript stack.
  • Use Jira to track tasks, report bugs, and collaborate with developers.
  • Reproduce, document, and escalate bugs found in CNC-related software workflows.
  • Perform manual and automated testing across desktop (Electron) and web applications.
  • Help improve QA processes to catch issues earlier in development, especially those related to CNC toolpath generation, machine control, or user interface.
  • Keep test documentation up to date and advocate for best practices in testing.

What We're Looking For

  • CNC experience – required (you understand G-code, toolpaths, machine setup, and common failure modes in CNC workflows).
  • Knowledge of CNC firmware, specifically GRBL and GRBLHAL – strongly preferred (candidates with this experience can dive deeper into debugging and root cause analysis right away).
  • Experience with software QA methodologies and defect tracking.
  • Proficiency with Jira for task management and bug reporting.
  • Strong skills in unit testing frameworks (Jest, Mocha, etc.) and test automation.
  • Familiarity with our stack: Electron, React, Node.js, TypeScript.
  • Ability to work independently, troubleshoot issues, and propose solutions.
  • Clear communication skills – you can explain technical issues to developers, non-technical staff, and customers alike.
  • A proactive mindset – you don't wait for bugs to be reported; you seek them out from other teams.

Nice to Have

  • Experience with end-to-end testing tools (Cypress, Playwright, Selenium).
  • Knowledge of CI/CD pipelines and integrating automated tests.
  • Background in customer-facing bug triage (working with support teams).
  • Experience with CAM software or other CNC controller software (e.g., Mach3, LinuxCNC).

Education & Experience

  • Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience) – preferred.
  • 3+ years in QA/testing roles (preferred).
  • 2+ years in software development environments (preferred).
  • CNC experience – required.
  • GRBL/GRBLHAL knowledge – strongly preferred.

Why Work at Sienci Labs?

You'll be part of a tight-knit team where your work has a direct impact on thousands of users. You'll help shape how our software interacts with real-world CNC machines, and you'll be the voice connecting development to the rest of the company. Clean code, smart testing, continuous improvement—and no bureaucracy.

Schedule

  • Monday to Friday

Work Location

  • In-person (preferred) or hybrid (must be local to Waterloo, ON N2V 1C6)

  • Company events
  • Dental care
