We are an early-stage venture developing a hardware-enabled product and are seeking a Software Engineering Intern for the summer to support core product development. This role works closely with our mechanical engineer and broader technical team to help produce a fully functioning prototype. The intern will focus on software that directly interfaces with mechanical and electromechanical systems, contributing to system control, integration, testing, and iteration.

This position is hands-on and development-focused, with responsibilities tied directly to the functionality and performance of the product.

• Develop and implement software that interfaces with mechanical and electromechanical components
• Support embedded or system-level programming related to product control and operation
• Collaborate closely with the mechanical engineer to integrate software with physical hardware
• Assist in debugging and troubleshooting hardware-software interactions
• Contribute to system architecture, control logic, and performance optimization
• Support testing, iteration, and refinement of functional prototypes
• Document code, system behavior, and design decisions to support future development

Depending on background and project needs, work may include:

• Embedded software development
• Control systems or logic for mechanical components
• Communication between sensors, actuators, and controllers
• Hardware-adjacent software and system integration
• Prototype validation and testing support

• Currently pursuing a degree in software engineering, computer engineering, computer science, robotics, or a related field
• Strong foundation in software engineering principles
• Interest or experience in robotics, embedded systems, or hardware-focused development
• Familiarity with one or more programming languages such as C, C++, or Python
• Comfort working in a hands-on, technical environment alongside physical hardware
• Ability to problem-solve independently and collaborate effectively in a small team

• Experience with microcontrollers, embedded platforms, or system-level programming
• Exposure to robotics, mechatronics, or control systems
• Prior project work involving hardware-software integration

• Direct involvement in early product development
• Experience working closely with mechanical and technical leadership
• Exposure to real-world hardware-software integration challenges
• Opportunity to contribute meaningfully to a functional product
• Scope and responsibilities aligned with experience level
