Proficiency in TypeScript/JavaScript, HTML5, CSS3, and responsive design
Experience contributing to backend development (C++, REST/WebSocket APIs, or similar)
Comfortable with Git, CI/CD, agile development, and DevOps practices
Very good spoken and written English for clear communication across teams and stakeholders
Industrial & Systems Expertise
Experience with industrial communication protocols such as OPC UA, ZeroMQ, or MQTT
Background in embedded Linux or real‑time systems
Knowledge of data visualization libraries for charts and real‑time plots
Awareness of cybersecurity considerations for device‑hosted webservers
Understanding of industrial HMI principles, including clarity, safety, and predictable operator workflows
