The Stack:

Most AI today is just a cool demo. We’re the engineers building the high-performance infrastructure that makes it actually work in the real world.

At 4PSA, we connect AI agents to real-time data and business processes, and we’re opening up a few internship spots for students who are serious about engineering.

The Mission:

This is a 100% hands-on internship. You won't be shadowing people or doing busy work. You will build and ship code that matters. During the program, you’ll work on:

• Real-time communication systems, cloud architecture, and scalable infrastructure
• High-performance platforms that stay reliable under pressure
• Contributing to Open Source projects
• Experimenting with cutting-edge and emerging technologies

If you excel during the summer, there’s a full position waiting for you.

Are you a fit?

This internship is for CS students or recent graduates who:

• Love taking systems apart to understand how they work
• Are comfortable working in Linux environment
• Are proficient in at least one of the following: JavaScript/TypeScript, Go, Node.js, Python, C/C++, Rust, PHP, Swift, Kotlin, Java
• Have a strong understanding of Data Structures, Algorithms, and OOP (not just for the exam)
• Are curious about SOA, REST architectures, and how clients and servers communicate
• Enjoy debugging, reverse engineering, and solving complex problems
• Care about code quality, performance, and clean engineering practices

Stop watching tutorials. Start building.
