HID Interaction Algorithm Engineer

Join the engineering team that fuses multimodal input to enable seamless interactions on human-computer interfaces like  Vision Pro. Human Interface Devices (HID) is looking for an Interaction Algorithm Engineer to help build the next generation of computing.

HID operates at the intersection of hardware, software, and design. The problems you solve will be multidisciplinary and require strong collaboration and communication skills. You’ll prototype ideas at the early stages of development and develop robust solutions through production.

In this role, you will:

• Prototype and define interactions end-to-end, in collaboration with HW, SW, and design partners
• Design user studies and leverage prototypes to define success criteria
• Develop processes for measuring key performance indicators
• Analyze data to identify and drive algorithm improvements
• Create and maintain core algorithms for new interactions and root-cause issues throughout the stack
• Communicate user impacts of technical challenges to cross-functional stakeholders

Minimum Qualifications

• 2+ years SW development experience (or equivalent internship / research experience)
• Proficiency in C++ and Python
• Proficiency in signal processing and/or machine learning
• Comfortable with 3D mathematics
• Experience developing interactions or input technologies
• Experience using genAI tools for SW development (Claude Code, Cursor, Codex, etc.)
• Able to communicate clearly and collaborate with cross-functional teams
• Excellent problem solving and root cause analysis skills
• BS/MS/PhD in Computer Science (CS), Electrical Engineering (EE), Human Computer Interaction (HCI), or a related field / equivalent experience

Preferred Qualifications

• Experience developing software with agentic workflows
• Experience developing software for Augmented Reality (AR) / Virtual Reality (VR) (ex. ARKit)
• Experience with Objective-C and/or Swift
