Rust’s profile has been rising sharply, boosted by a February cybersecurity report from the White House calling for memory safe languages to replace C and C++. Rust is yet again the most admired programming language (72%).

What this means for systems engineering roles: When hiring for infrastructure, DevOps, or systems programming positions, Rust experience signals candidates who understand modern security-first development practices.

Go and Kotlin: The Performance Specialists

Go continues gaining traction for backend development and API work, while Kotlin has become Google’s preferred language for Android development. These aren’t just trendy choices—they represent specific technical solutions to scalability and performance challenges.

Market Trends Transforming Hiring Requirements

The AI Integration Reality

The +5 point increase for FastAPI is one of the most significant shifts in the web framework space, signaling a strong trend towards using Python for building performant APIs. This reflects how AI integration is becoming table stakes, not a nice-to-have feature.

Practical application: When hiring backend developers, evaluate their experience with AI-ready frameworks, not just traditional web development tools.

Memory Safety and Security Focus

C’s popularity appears to be on the wane, falling from fourth to ninth place on the Spectrum ranking and from 7th to 13th on the Jobs ranking. This shift represents a fundamental change in how we approach systems programming and security.
