Integration developer Jobs in Etobicoke, ON

We are looking for a Senior Embedded Build, Release & Integration Developer to
own the infrastructure and integration path between software development, external
technology partners, and formal product QA.

Our products are distributed embedded systems combining multiple processors and
independently versioned software components: bare-metal and RTOS firmware,
embedded Linux, inter-processor communications, networking and audio services,
vendor SDKs, and internally and externally developed code.

This role is responsible for making those pieces work together reliably.

Advantages
What Success Looks Like
● Developers do not lose productive time fixing shared build infrastructure.
● External software deliveries are integrated predictably without destabilizing active
development.
● The team always knows which firmware and software versions belong together.
● Technical integration problems are caught and diagnosed before becoming
product-level QA problems.
● QA receives stable, traceable, and documented builds.
● Senior developers spend less time on recurring build, merge, and release work.
● Cross-system bugs are diagnosed systematically rather than relying on tribal
knowledge.
● Useful AI-assisted engineering capabilities evolve from individual tool usage into
repeatable team workflows.

Responsibilities
What You Will Own
Build & CI Infrastructure
● Maintain build servers, build scripts, containers, toolchains, Yocto/BitBake
environments, and CI pipelines.
● Keep builds reproducible and shared development infrastructure reliable.
● Investigate and resolve build and CI failures.
● Automate recurring build, integration, and release tasks.
● Maintain artifacts, versioning, tagging, and release traceability.
Software & Vendor Integration
● Integrate software and firmware delivered by internal teams and external
technology partners.
● Maintain integration branches and resolve complex Git integration conflicts.
● Manage compatibility across independently versioned firmware, Linux software,
middleware, and vendor components.
● Maintain clear version matrices defining validated component combinations.
● Produce traceable integrated builds for development, QA, and manufacturing.
● Investigate problems spanning firmware, Linux, middleware, transport, and
processor boundaries.
System Integration & Technical Validation
● Validate software changes that require system-level technical knowledge beyond
normal product QA.
● Verify bug fixes and technical stories by examining logs, services, processes,
IPC, network traffic, system state, and interactions between processors and
software components.
● Investigate systemd/journald logs, crashes, traces, and runtime behavior to
confirm whether changes actually resolve the underlying problem.
● Develop repeatable tests for technical requirements that are difficult to verify
through user-facing QA.
● Verify compatibility across firmware/software version combinations.
● Work with developers when failures cross subsystem boundaries and help
determine where the problem originates.
● Automate recurring integration and system-level validation where practical.
Developers remain responsible for testing the correctness of their own changes.
Product QA remains responsible for user-facing functionality and regression testing.
This role owns the technical validation layer between those two, particularly where
verification requires understanding the internals of the system.

Agentic Debugging & Engineering Automation
Help us move beyond AI autocomplete and chatbot usage toward automated,
codebase-aware engineering workflows.
Potential applications include:
● Giving coding agents controlled access to multiple repositories, Git history, build
results, logs, and test results.
● Automating cross-repository investigation of difficult system-level bugs.
● Tracing interfaces, dependencies, and changes across subsystems.
● Comparing failing and known-good builds.
● Generating diagnostic tests and investigation steps.
● Integrating AI-assisted analysis into build, debugging, and failure-triage
workflows.
We are particularly interested in workflows where substantial automated analysis can
reduce engineering time spent investigating complex failures.

Qualifications
What We Need
Strong hands-on experience with the following core technical requirements:
● Yocto / BitBake build systems and embedded Linux
development/troubleshooting — mandatory.
● C/C++ codebases in embedded environments.
● Advanced Git: branching, merging, rebasing, and complex conflict resolution
across vendor and internal development streams.
● Automated build or CI infrastructure such as Jenkins, GitLab CI, GitHub
Actions, or custom build servers.
● Python, Bash, or similar scripting for build, release, and engineering
automation.
● Docker or comparable container tooling for reproducible build environments.
● Systematic debugging across subsystem boundaries, including systems
involving multiple processors, IPC, serial consoles, and system logs such as
systemd/journald.
● Ability to investigate unfamiliar systems by gathering evidence, forming
hypotheses, and isolating root causes.
Experience with FreeRTOS, Zephyr, inter-processor communication, audio/networking
stacks, hardware-in-the-loop testing, or third-party embedded SDKs is highly valued.

Important Scope Note
This is an embedded systems role, not a cloud/SRE role.
Candidates whose DevOps experience is primarily Kubernetes, AWS/Azure/GCP,
Terraform, web deployment, or cloud operations must also have substantial hands-on
embedded Linux build and system-integration experience.

Summary
Agentic Engineering Experience — Asset
Hands-on experience building automated LLM or coding-agent workflows is an asset,
particularly in areas such as:
● Repository-scale or multi-repository code analysis.
● Integrating LLM APIs or coding agents with repositories, build/test infrastructure,
or diagnostic data.
● Tool calling, MCP, agent orchestration, or similar mechanisms.
● Automated debugging, test generation, failure triage, or engineering analysis.
Interactive use of ChatGPT, Gemini, Copilot, or similar tools alone does not
constitute this experience.
This experience is an asset, not a substitute for strong embedded systems and
integration fundamentals.
