Summer 2027 Internship - Software Engineering

As a General Matter Software Engineering Intern, you will help develop performant, safe, and high-quality software. Your work will support code where reliability, performance, and safety are of utmost importance. You will work closely with cross-functional teams, including electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists, and physicists. If you seek high-impact work and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to reach out to join our team.

We're hiring interns across three focus areas:

• Backend interns will help build high-performance services and APIs that coordinate control systems, manage state across distributed hardware, and expose interfaces for monitoring and operations.
• Distributed systems interns will support the development of fault-tolerant coordination systems, real-time data pipelines processing high-throughput sensor telemetry, and the infrastructure that keeps critical systems running reliably at scale.
• Tooling interns will help build the developer platforms, CI/CD systems, observability tools, and deployment infrastructure that let our team iterate rapidly and safely in a production environment where mistakes have physical consequences.

• →Assist in designing and implementing high-performance software systems in C++ and Python, with a focus on reliability and maintainability.
• →Support the architecture of solutions, contributing to decisions around system design, performance trade-offs, and technology selection.
• →Participate in technical design reviews and code reviews, learning and helping uphold engineering best practices across the team.
• →Help build and maintain automated testing and CI/CD pipelines to support software quality at scale.
• →Work closely with senior engineers, contributing to progress on complex, ambiguous technical problems.

• Current undergraduate or graduate student pursuing a degree in Computer Science, Engineering, or a related discipline.
• Proficiency in C++ and/or Python.
• Strong CS fundamentals, such as algorithms, data structures, concurrency, and system design.
• Collaborative team member who thrives in fast-paced, multidisciplinary environments and is eager to learn.

• Exposure to distributed systems, observability tooling, or infrastructure as code.
• Experience with Python ecosystems for data pipelines, automation, or backend services.
• Coursework or project experience with C++ performance optimization, profiling, or low-level systems programming.
• Familiarity with Linux system programming, including threading models, IPC, or low-level kernel interfaces.
• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).

• Ability to work extended hours and weekends as necessary.
