Job description

Senior Software Developer — Architecture designs, develops, and maintains high‑performance software components for LCMS/inspection systems within a multidisciplinary engineering context. They ensure the technical quality of deliverables, guide architectural decisions, mentor teams (engineers and interns), and work closely with Product, QA and Services to ensure solutions meet customer requirements and industry standards.

Responsibilities

• Design, develop, test and optimize libraries and applications in C++ (C++17/20) and C# (.NET/WPF) on Windows and Linux within Agile teams.
• Define and document software architecture, APIs and critical module interfaces.
• Guide technology choices and establish development standards (style, CI/CD, code reviews, testing).
• Implement and maintain CI/CD pipelines, continuous integration of unit and integration tests, and automated deployment.
• Write and maintain test suites (unit, integration, performance); apply TDD where appropriate.
• Perform profiling, optimization and performance validation (memory, latency, parallelism).
• Deploy static analysis tools, sanitizers and practices to limit regressions and memory issues.
• Produce technical documentation (designs, test plans, performance manuals) and ensure requirements traceability.
• Act as a technical mentor: code reviews, pair programming, knowledge transfer and training for junior team members.
• Collaborate with Product, Sales and Services to analyze customer needs, validate requirements and prioritize fixes/enhancements.
• Conduct technology watch and build prototypes to evaluate relevant new approaches.
• Perform any other duties related to the role as assigned by management.

Qualifications

• Bachelor’s degree in Computer Engineering, Software Engineering, Computer Science or a related field (or equivalent experience).
• Minimum 7 years of relevant software development experience (or 5+ with proven achievements).
• Demonstrated experience in software architecture and technical leadership of projects.
• Experience in performance‑critical environments (real‑time processing, acquisition, signal processing or equivalent) is an asset.
• Strong command of modern C++ (C++17/20): memory management, multithreading, concurrency, design patterns.
• Good knowledge of C# and UI development (WPF/.NET); ability to work on a mixed C++/C# codebase.
• Experience developing on Windows and Linux; familiarity with cross‑platform toolchains.
• Strong debugging and profiling skills (e.g., Valgrind, perf, VTune) and algorithm optimization.
• Mastery of software quality practices: unit testing, TDD, BDD, code reviews, CI/CD.
• Familiarity with integration/deployment tools (Git, GitHub Actions / Azure DevOps / GitLab CI).
• Familiarity with static analysis tools and sanitizers (clang‑tidy, cppcheck, Address/Undefined Sanitizer).
• Rigor, autonomy, analytical mindset and excellent communication skills.
• Ability to prioritize and deliver according to project timelines.
• Professional English (reading/writing/speaking) for documentation and international collaboration.

Assets (Optional)

• Experience in computer vision, AI/ML applied to image or signal processing.
• Knowledge of real‑time systems, data acquisition and hardware/firmware interfaces.
• Experience with containers (Docker), light orchestration and cloud deployment (Azure, AWS).
• Experience in embedded development or SIMD/GPU‑optimized processing engines.
• Experience in instrumentation and measurement (LCMS or inspection systems) or a similar domain.
