About The Position

Gems Setra is seeking a Senior Software Engineer to join the software team and deliver reliable products used in safety and critical environments. In this role, you will design, develop, and maintain software spanning several embedded Linux systems and related products, with a focus on reliability, diagnosability, and secure, maintainable engineering practices.

Requirements

• Bachelor’s degree in engineering and 5-10 years of related experience, or an equivalent combination of education and experience
• Demonstrated professional software engineering experience, with significant work delivering production systems in C++ on Linux; typically 6 years.
• Strong proficiency in C++ and Linux development and debugging (including command-line workflows and scripting such as shell/Python where used).
• Experience with pub/sub messaging fabrics such as MQTT, Kafka, Rabbit.
• Experience with Qt for Linux application development (UI and/or tooling) in embedded devices
• Experience with modern build systems and packaging workflows for embedded targets (e.g., cmake, cross-compilation, ARM build targets).
• Proven track record collaborating across software, hardware, and quality disciplines in product environments.

Nice To Haves

• Familiarity with industrial/building communication stacks and protocols, including BACnet® and Modbus, and comfort diagnosing network/protocol issues.
• Experience with IoT/edge gateway integration patterns and multi-protocol systems.
• Experience with security validation practices and tools (e.g., SAST/DAST, threat modeling).
• Exposure to web-facing components or embedded web UIs that complement edge products (team stack includes embedded web competency areas).

Responsibilities

• Design and implement product software features across edge/embedded Linux components and related integrations used in environmental and power monitoring ecosystems, including network/protocol interactions.
• Deliver production-quality C++ components on Linux, including performance tuning, memory/resource optimization, and long-term maintainability.
• Contribute to device build/release workflows, including cross-compilation and packaging patterns used by the team (e.g., cmake-based builds and ARM build targets).
• Develop and/or maintain embedded UIs or operator-facing tooling where applicable, including Qt-based and embedded web applications for Linux targets.
• Implement and troubleshoot industrial communications and building-automation integrations using industry protocols, including inspection of traffic and diagnosis of field issues.
• Collaborate cross-functionally with hardware, quality, and product teams to translate requirements into robust designs, and to drive verification and validation expectations for regulated or reliability-focused environments.
• Improve engineering effectiveness by introducing or strengthening development practices (code reviews, automated checks, CI/CD direction, and repeatable build/test flows) aligned to the team’s product competencies.
• Support field and manufacturing issue resolution by reproducing issues, performing root-cause analysis, and delivering fixes with clear documentation and controlled release processes.
• Exemplify solid technical decision-making, including architecture discussions, coding standards, and secure development awareness within product software.
