Senior Java Engineer

About the role

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.

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.

Qualifications

• 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).
• Bonus:
• Python scripting, Qt/GUI frameworks, embedded firmware (C/C++).
• 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.

Benefits

• Medical Insurance/ Vision Insurance/ Dental Insurance
• 401(k) & Retirement Savings Plan (RSP)
• Short Term Disability Insurance
• New Child Leave
• Paid Time Off
• Paid Company Holidays per year
• Paid Sick Days (earned based on hours worked)
