Senior Java Engineer

GenScript/ProBio•Redmond, WA

19h•$140,000 - $170,000

About The Position

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.

Requirements

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).
Technical Skills: Java Expertise: Core Java, multi-threading, JavaFX/Swing, Maven, NetBeans.
Hardware Protocols: USB, Serial, SPI, I2C (hands-on debugging).
Soft Skills & Culture Fit: “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.

Nice To Haves

Python scripting, Qt/GUI frameworks, embedded firmware (C/C++)

Responsibilities

Java-Centric Development: 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).
Hardware Integration: 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.
Database & Systems Management: 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.
