Senior Java Engineer

Senior Java Engineer

Redmond, Washington, United States

Architect and develop mission-critical Java software for next-generation automated instruments, enabling precise control of microcontrollers, valves, sensors, and pressure regulators. Own the full-stack software infrastructure, from low-level hardware communication (USB/SPI/serial) and embedded firmware integration to GUI design, data pipelines, and database management, ensuring reliability for end-user scientists.

Lead high-level Java development for instrument control, including multi-threaded applications, GUI frameworks (JavaFX/Swing), and hardware abstraction layers. Modernize legacy Java codebases while maintaining backward compatibility with embedded systems (custom controller PCB based on industry standard microcontroller). Interface with microcontrollers, sensors, and actuators via protocols (SPI/I2C/serial) and real-time messaging systems. Debug and optimize low-level communication between software and hardware components. 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. 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.

This is a fully onsite role due to the hands-on nature of instrument control, hardware integration, and close collaboration with engineering and scientific teams.

Requires Bachelor's degree in Computer Science, Computer Science & Engineering, Software Engineering, Electrical Engineering or a related Engineering field. Experience: 6–8 years in Java development for instrumentation/robotics/embedded systems (or equivalent). Java Expertise: Core Java, multi-threading, JavaFX/Swing, Maven, NetBeans. Hardware Protocols: USB, Serial, SPI, I2C (hands-on debugging). Bonus: Python scripting, Qt/GUI frameworks, embedded firmware (C/C++). "Product mindset": Balance technical rigor with end-user needs (scientists' workflows). Communicate complex ideas clearly to both engineers and non-technical stakeholders. Autonomy: Self-driven in ambiguous, R&D-paced environments.
