Description:

Architect and develop mission-critical Java software for next-generation automated instruments, enabling precise control of microcontrollers, valves, sensors, and pressure regulators.

Responsibilities:

Java-Centric Development:

- Design and maintain relational databases for instrument metadata, experiment logs, and process analytics.
- Implement data analysis pipelines (Python/Java) for real-time monitoring, post-processing analysis and process optimization.
Technical Leadership:
- Act as SME for software architecture: document APIs, enforce good design practices, and mentor junior engineers if needed.
- Drive CI/CD pipelines, version control (Mercurial/Git), and automated testing frameworks.
