Sun Automation builds industrial software that connects operators to machines with clarity and speed. This onsite role in Glen Arm, MD focuses on developing a next-generation Human Machine Interface (HMI) for corrugated systems powered by Siemens Unified Architecture, bringing together responsive UI work, backend services, and reliable PLC integration.

You will work on a stack spanning React and modern JavaScript/TypeScript, Python backend services, OPC UA communications with Siemens PLCs, and potentially Elixir for concurrency- and fault-tolerance-heavy components in cloud or service environments.

What you will do

Design and build a responsive, real-time HMI using React and modern JavaScript/TypeScript.
Develop backend services in Python for data acquisition, processing, and API layers.
Architect and implement dependable communication with Siemens PLCs via OPC UA.
Build and maintain scalable, fault-tolerant cloud systems, leveraging Elixir for concurrency-focused components.
Partner with controls engineers to translate machine recipes into operator-friendly interfaces.
Implement real-time data streaming, alerting, and visualization systems.
Support industrial reliability goals through observability and performance practices.
Contribute to deployment pipelines and edge/on-premises system architectures.
Write clear documentation and participate in code reviews.

What you bring

React and strong JavaScript/TypeScript skills required.
Experience building robust backend systems in Python or C++ required.
Hands-on OPC UA experience required, including client/server work, data modeling, and security.
Solid understanding of distributed systems, networking, and API design required.
Experience with industrial automation, PLCs, or SCADA/HMI platforms required.
Familiarity with asynchronous programming and real-time data handling required.
Ability to debug complex interactions between hardware and software required.
Preferred: experience with Siemens PLCs (for example, S7 series and TIA Portal ecosystem).
Preferred: exposure to Elixir/Erlang or other high-concurrency, fault-tolerant systems.
Preferred: industrial protocols beyond OPC UA (for example, Modbus or Profinet).
Preferred: experience deploying to edge devices or other on-prem industrial environments.
Preferred: familiarity with Docker and CI/CD pipelines.
Preferred: understanding of cybersecurity practices in industrial networks.
