Senior Software Engineer

Onto Innovation•Wilmington, MA

About The Position

Onto Innovation is seeking a Software Engineer to join the Inspection Business Unit (IBU). This role requires an individual who can maintain a global, system-level view of a complex inspection platform (optics, mechanics, electronics, and software) and also delve into specific layers when necessary. The critical skill sought is the ability to maintain an accurate mental model of a complex system and effectively map customer problems to technical solutions, especially given the rise of AI coding agents.

Requirements

PhD, MS, or Bachelor's degree in Electrical Engineering, Computer Science, Applied Mathematics, Physics, or related field.
Demonstrated ability to reason about systems at multiple levels of abstraction—from high-level architecture down to implementation details.
Strong problem-solving, analytical, and communication skills; able to articulate complex system behavior clearly to both technical and non-technical stakeholders.
Competency (or demonstrable coursework) in at least one numerically focused environment such as Python or MATLAB, including linear algebra, image processing, and/or machine learning libraries.
Competency (or demonstrable coursework) in at least one compiled or production language used in large-scale software systems, such as C++, C#, or Java.

Nice To Haves

Experience in semiconductor inspection, machine vision, robotics, or similar highly technical domains where hardware/software co-design is essential.
Track record of diagnosing cross-subsystem issues that span optics, electronics, firmware, and application software.
Experience effectively using AI coding agents (e.g., Copilot, Cursor, Aider, or similar) to accelerate development.
Experience with software development methodologies such as Agile, Scrum, or Kanban.
Experience with version control and CI/CD practices.
Experience debugging complex multi-threaded software environments.
Familiarity with embedded systems, hardware communication protocols, and/or real-time constraints.

Responsibilities

Build and continuously refine an accurate mental model of the full Onto inspection platform—optics, motion, electronics, image acquisition, and software stack.
Translate customer problems and application requirements into well-scoped engineering tasks by reasoning across subsystem boundaries.
Agility to zoom from system-level architecture down into any specific areas: databases, algorithm performance, hardware, data flow, GPUs, GUIs, etc.
Participate in New Product Development (NPD) alongside hardware engineers, application engineers, Technical Project Managers, and Program/Product Managers.
Apply machine learning, image processing, computer vision, mathematics, and optics to develop algorithms integrated into Onto inspection platforms.
Develop or contribute to optical imaging modeling/calibration and/or image segmentation, classification, and detection algorithms.
Write, test, and debug software to ensure high-quality, reliable operation; optimize for performance and scalability.
Perform or lead (based on experience) requirement analysis, detailed software design, production code development, and associated test plans.
Participate in design/code reviews collaborating with systems engineers, software developers, and other technical staff.
Leverage AI coding agents to accelerate implementation, while maintaining ownership of architecture decisions, design integrity, and code quality.
Stay current with academic research and industrial practices in machine vision inspection, image processing, machine learning, and AI-assisted engineering.
Document software designs, system-level rationale, development processes, and troubleshooting steps.
Support teammates and, at senior levels, provide technical mentorship—especially in systems thinking.
Contribute to improving the team's development workflows and tooling, including AI-assisted practices.
