Job description

We are seeking a highly experienced and motivated Senior Automation Software Engineer to lead the design, development, and deployment of automation solutions across our precision systems. In this role, you will play a pivotal part in enabling automated control of high‑precision optical alignment systems, including those using nano‑positioners to accelerate R&D, manufacturing, and testing processes.

Responsibilities

• Architect and implement automation software for real‑time control of precision hardware, including optomechanical alignment systems and nano‑positioning stages.
• Develop algorithms and motion sequences for sub‑micron optical alignment, calibration, and measurement routines.
• Integrate motion control systems (e.g., piezoelectric nano‑positioners) with cameras, sensors, and software platforms to automate complex alignment workflows.
• Design and maintain scalable automation frameworks for functional testing, system validation, and performance monitoring.
• Collaborate with mechanical, optical, and systems engineers to define software interfaces for precision hardware.
• Guide junior team members and lead code reviews, architecture discussions, and technical decision‑making.
• Ensure high standards of software quality, reliability, and repeatability in both lab and production environments.

Required Qualifications

• Bachelor’s or Master’s degree in Computer Science, Mechatronics, Electrical Engineering, or related fields.
• 8+ years of experience in automation software engineering with a focus on motion control or hardware integration.
• Strong programming skills in Python, C++, or C# with a focus on real‑time systems or hardware interfacing.
• Hands‑on experience working with nano‑positioning systems (e.g., PI, Aerotech, Newport), motion controllers, or precision actuators.
• Deep understanding of control systems, sensor integration, and closed‑loop feedback.
• Familiarity with laboratory instrumentation, optics, and high‑precision metrology.
• Experience developing and integrating with software tools for data acquisition, automation (e.g., LabVIEW, MATLAB, or custom platforms), and visualization.

Preferred Qualifications

• Experience with image processing and computer vision.
• Experience with optical alignment techniques (active/passive), beam steering, or interferometry.
• Familiarity with image processing libraries (e.g., OpenCV) for vision‑guided alignment.
• Knowledge of automation frameworks for system‑level testing and validation.
• Experience with high‑vacuum or cleanroom‑compatible automation systems.
• Strong debugging, documentation, and cross‑disciplinary communication skills.
• Experience with Jira for project and task tracking.
• Experience with Arena PLM.
