Job description

Description:

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:

  1. Java-Centric Development:
  2. 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).
  3. 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.
  4. 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.
  5. 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.

Onsite Requirement: 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.

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.

Benefit:

  • 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)
  • Compassionate Leave
  • Jury Duty Leave
  • Float day
  • Personal days

Perks: 

  • Free colleague meals during shift
  • Onsite massages Charis
  • Onsite gyms

Compensation:
Salary range: $140,000 - $170,000 total compensation, including bonus, depending on experience and qualifications.
