  • Supporting AI-related infrastructure and intelligent tooling initiatives
  • Enhancing developer tooling, automation, and deployment systems
  • Contributing to visualization and interactive engineering experiences
  • Collaborating across software, infrastructure, and simulation teams

Requirements
We are looking for engineers with strong technical fundamentals, curiosity, and the ability to ramp up quickly in complex environments.
You may be a strong fit if you have:
  • 3 to 6 years of professional software engineering experience
  • Strong programming skills in one or more languages such as Python, C++, Rust, Go, Java, or JavaScript
  • Experience building backend systems, APIs, or distributed services
  • Familiarity with Linux-based development environments and Git workflows
  • The ability to independently drive technical projects and collaborate effectively across teams
  • Strong problem-solving ability and attention to detail
  • A degree in Computer Science, Engineering, Physics, Mathematics, or a related technical field

Preferred Skills
  • Experience with cloud infrastructure such as AWS, GCP, or Azure
  • Familiarity with Docker, Kubernetes, or containerized environments
  • Exposure to AI infrastructure, ML systems, or data engineering workflows
  • Experience with performance optimization or distributed computing systems
  • Interest in scientific computing, GPU acceleration, or simulation platforms

Why Flexcompute?
Flexcompute offers the opportunity to work on deeply technical challenges with real-world impact across aerospace, semiconductors, energy, advanced computing, and AI-driven engineering.
You will join a fast-growing team building next-generation technologies at the intersection of GPU computing, cloud infrastructure, scientific simulation, and AI. Engineers at Flexcompute are given significant ownership, access to world-class mentors, and the opportunity to contribute to products used by some of the world's most innovative organizations.
