Mainframe Z Os System Programmer Jobs in Quebec (NOW HIRING)

dcbel Inc. (www.dcbel.energy) designs and sells residential products to make clean, efficient, and sustainable energy accessible to all because everyone in the world deserves energy without compromise.

dcbel is at the leading edge of the residential energy revolution. Its products enable decentralized energy consumption and production through its vertically integrated suite of energy hardware and software products, and their supporting infrastructure.

Our flagship product, dcbel Ara, is a Home Energy Station that gives everyone ownership over their energy supply by using solar power to charge their EV and power their home, unlocking their EVs battery for blackout protection, backup power (V2H) and grid services (V2G), and optimizing the energy flow between their solar panels, EVs, stationary battery and the grid.

The opportunity

dcbel is looking for an Embedded Quality Developer to join our Firmware/OS team, responsible for designing, implementing, and scaling Python-based automated validation infrastructure and test suites for embedded and cloud-connected products. The role focuses on increasing defect detection before release and improving confidence in device, protocol, and system-level behavior under real operating conditions, spanning hardware-in-the-loop, integration, protocol, system, regression, and release validation, with a strong emphasis on reproducibility, diagnostics, and measurable quality improvement.

Main Responsibilities

• Implement Python test suites, fixtures, and reusable test libraries for device behavior, interfaces, and end-to-end workflows.
• Integrate automated validation into CI/CD pipelines with quality gates, artifact collection, failure triage data, and clear pass/fail criteria.
• Contribute to early testability and risk reduction by reviewing requirements, interfaces, and acceptance criteria where useful.
• Use field logs, telemetry, and failure data to expand regression coverage and improve validation of device-to-cloud interactions.
• Reduce flakiness, improve observability and diagnosability, and optimize execution time and infrastructure stability.
• Work closely with firmware, OS, cloud, and systems engineers to reproduce failures, isolate root causes, and support release decisions.
  

Key Requirements

• Bachelors in Engineering and ideally dual diploma in both Electrical and Software engineering
  
• Strong hands-on experience developing Python-based automated validation frameworks and test suites for embedded systems.
• Experience with CI/CD-driven validation, automated quality gates, and test result analysis for hardware-integrated and cloud-connected products.
• Experience validating systems that combine custom hardware, embedded software, communications interfaces, and backend connectivity.

Bonus Skills

• Bilingual English and French written and spoken.

Profile

• Working knowledge of test planning, traceability, defect management, and reproducible failure analysis.
• Familiarity with embedded and industrial interfaces such as CAN, Modbus, RS-232, Ethernet, and other device communication layers.
• Familiarity with cloud-connected embedded products, device-to-cloud interactions, OTA/update validation, and end-to-end reliability.
• Knowledge of system safety, regulatory constraints, and the test evidence expected in compliance-oriented product development.
• Demonstrated ability to use AI tools effectively to accelerate test development, increase coverage, analyze failures, and improve engineering throughput while applying sound judgment.
• Strong understanding of test reliability, maintainability, diagnostics, and data-driven quality metrics, including identification and remediation of flaky tests.
• Entrepreneurial mindset, result oriented and strong EQ.
• Autonomous, good teammate with strong problem-solving skills.
  

What's in it for you

• Be part of a company that is backed by numerous globally respected investors and has world-changing patents in an industry changing for the first time in history.
• Grow your professional experience amongst blue chip partners and a close-knit team of committed and experienced energy experts who deeply care about the work they do.
• Full benefits package including Health insurance, Health virtual care, employee stock options plan (ESOP) and flexible hours. Parking available or with our employer commute program a short walking distance from Metro Namur.
