Embedded Software & Field Tools Developer

Octasic•Montreal, QC

About The Position

We are looking for a C++ software engineer with a systems mindset to own the design, development, and maintenance of in-house tools used for RF mode testing, real-time system monitoring, and log analysis across our product portfolio. You will work at the intersection of embedded communication protocols and RF system testing— building tools that product teams rely on daily to assess and validate the quality of our products. As our tooling continues to expand across product lines and field deployments, you will play a central role in making it scalable, maintainable, and adaptable with each release. You will collaborate closely with Software developers, Hardware and RF engineers, and System and field test teams.

Requirements

Bachelor's degree in Software Engineering, Computer Engineering, Electrical Engineering, Computer Science, or equivalent practical experience
Strong, hands-on C++ and Python development experience — this is the primary language of the role; candidates must be comfortable writing production-quality C++ code
Experience with TCP socket programming and HTTP client/server communication for hardware-software integration
Familiarity with RF testing concepts or lab instrumentation control (signal generators, spectrum analyzers, power meters)
Hands-on experience with packet capture and network analysis (Wireshark or equivalent)
Experience with Git, Linux environments, and collaborative development workflows
Strong debugging and root-cause analysis skills in integrated hardware/software systems

Nice To Haves

Experience with multi-threaded C++ applications — concurrent programming, thread safety, and performance optimization
Experience with LTE/5G PHY layer concepts — receiver sensitivity, test models, waveform testing, power control, predistortion
Experience with data engineering: message brokers (MQTT, Kafka), ETL pipelines, relational database design (PostgreSQL), dashboarding tools (Grafana, Prometheus)
Familiarity with pytest and Playwright for test automation frameworks
Experience with REST API design and integration
Background in mission-critical, defense, or aerospace communication systems
Familiarity with embedded telecom stacks and real-time embedded software

Responsibilities

Design, develop, and maintain the core tooling engine and modules primarily in C++ and PY, following clean, maintainable coding standards
Build and maintain TCP socket and HTTP client/server communication layers in C++ to interface with embedded subsystems and backend services
Develop C++ interfaces to control and query external RF lab instruments (power meters, signal generators, spectrum analyzers) via standard instrument control protocols
Write Python scripts to support automation, glue logic, and rapid prototyping where appropriate
Implement and support RF mode test features including receiver sensitivity testing, test model signal generation, and waveform testing
Extend tool support for transmit/receive conformance testing and REST API integration
Develop and maintain a monitoring, analytics and data management system for Octasic products, backed by a C++ and PY FW serving real-time system status
Build real-time packet capture analysis pipelines for live field monitoring
Support continuous evolution of Data analytics and monitoring, aggregating telemetry and system data to support performance analysis, KPI reporting, troubleshooting, and validation of our wireless communication products
Support offline log analysis workflows and automated report generation (call metrics, scan metrics, registration rates)
Integrate tooling features with a data platform using message-broker architecture, relational database storage, and visual dashboarding
Support data pipeline extensions: geolocation, positioning, and periodic telemetry collection
Contribute to pipeline performance and reliability: threading, error handling, schema versioning
