  • Proven experience contributing to or leading software architecture initiatives, from design and planning through implementation and operational support.
  • Strong object-oriented programming, debugging, and troubleshooting skills.
  • Excellent communication skills and the ability to work directly with clients and cross-functional teams.
  • Self-driven, dependable, and comfortable working independently.
  • Ability to learn new technologies and domains quickly.
  • Creative problem-solving mindset with a willingness to challenge existing approaches.
  • Hands-on experience with hardware integration testing and troubleshooting for real-time simulation systems.
  • Authorized to work in the United States.
Preferred Skills & Experience
  • Experience with real-time systems using technologies such as C++, MFC, Python, SQL, VBA, PHP, JavaScript, Perl, Qt UI, and batch scripting.
  • Familiarity with REST APIs and web service integrations.
  • Exposure to GIS or spatial data systems.
  • Experience with Azure cloud development and deployment is a plus.
  • Background in AI, machine learning, or large-scale data systems is a plus.
  • Experience working with Kanban-style tools such as Trello.
  • Ability to manage multiple priorities in a fast-moving environment.
  • Strong interpersonal skills and a collaborative working style.
  • Fluency in English for technical communication; French language skills are a bonus.
  • Experience with modeling and simulation software or familiarity with the railway industry is a plus.
  • Demonstrated leadership or mentoring experience, with a focus on team growth.
