Job Summary & ResponsibilitiesJob Summary: The
Staff Software Engineer will play a key role in architecting and developing software that enables reliable wafer handling, robotics coordination, safety interlocks, motion control, system orchestration, and factory automation interfaces for a standardized EFEM (Equipment Front End Module) platform. This role involves designing and implementing reusable software components, integrating hardware subsystems, and contributing to a scalable architecture adopted across Onto products.
The ideal candidate has strong experience in structured real-time software design, complex electromechanical systems, HW/SW integration.
Key Responsibilities:- Act as lead software engineer on new projects, determining requirements and a robust design, and collaborating with hardware engineers to ensure seamless hardware-software integration
- Develop software modules for wafer-handling robotics, load ports, sensors, pre-aligners, and system-level orchestration
- Design of extensible APIs, control interfaces, and internal communication frameworks
- Optimize software performance and ensure scalability
- Provide mentoring and guidance to more junior team members
- Develop automated tests, simulation tools, and validation frameworks for EFEM software
- Perform system-level troubleshooting, data analysis, and optimization of EFEM software performance
- Identify and drive process, architecture, and code quality improvements across the EFEM software stack and across multiple teams/modules
QualificationsQualifications- Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
- Proven experience (10+ years for Staff level) in software development for highly technical applications, including leading architecture/design of large-scale, mission-critical software systems
- Experience driving technical roadmaps, resolving cross-team dependencies, and making tradeoffs across performance, maintainability, and schedule.
- Strong knowledge of hardware-software integration and experience working with complex systems.
- Deep expertise in .NET including runtime behavior, performance, threading, and memory management.
- Strong C# proficiency using modern features
- Experience structuring systems using clean architectural patterns, dependency injection, modularity, and API versioning.
- Mastery of concurrency design: multithreading, synchronization, message passing, actor models, and preventing deadlocks/race conditions.
- Experience designing/maintaining APIs and integration points:
- Internal IPC (gRPC, message bus, shared memory, etc.)
- External interfaces (factory host integration, equipment automation)
- Demonstrated experience debugging complex multi-threaded environments.
- Ability to travel both domestically (~10%) and internationally (infrequent and only when needed)
Preferred Qualifications:- Experience in the semiconductor industry, robotics, or similar sector
- Experience with SEMI standards such as E84, E87, E90, E30, E37
Compensation & Growth• Base Salary Range:
$115,200.00 - $172,800.00, offered in good faith and based on experience, location, and qualifications.
