We are seeking a skilled and experienced Software Engineering Intern, to work on Systems Modeling & Benchmarking.

Founded by Brijesh Tripathi and Dali Kilani, who bring experience from Nvidia, Apple, Tesla, Intel, Lifen, and Zoox, FlexAI is not just building a product – we’re shaping the future of AI. Our teams are strategically distributed across Paris, Silicon Valley, and Bangalore, united by a shared mission: to deliver more compute with less complexity.

 If you're passionate about shaping the future of artificial intelligence, driving innovation, and contributing to a sustainable and inclusive AI ecosystem, FlexAI is the place for you !

Position Overview:

FlexAI is seeking a brilliant and motivated Software Engineering Intern to join our team in Paris. In this hybrid role, you’ll explore performance modeling beyond LLMs, build advanced system benchmarks, and contribute to the development of our frontend tools.

You’ll work alongside experts at the intersection of AI infrastructure, performance engineering, and user-facing analytics. If you’re passionate about systems, algorithmics, and performance — this is a unique opportunity to learn, contribute, and grow in a fast-paced AI startup environment.

What you’ll do:   

• Model System Performance: Work on mathematical and algorithmic models to characterize and predict performance across various AI workloads (beyond LLMs).

• Develop Benchmarking Tools: Design and implement benchmarking pipelines to evaluate models, workloads, and infrastructure components.

• Contribute to Frontend Development: Build user-facing components using React, delivering intuitive dashboards and benchmark visualization tools.

• Collaborate Across Teams: Work closely with both backend and infrastructure engineers to ensure modeling and benchmarking results are actionable and integrated into product workflows.

• 
  

What you’ll need to be successful:

• Final-year student, or 4th-year from a top engineering school, ideally with a strong background in mathematics, algorithmics, and software engineering.

• Strong coding skills, particularly in Python, React, and/or Linux environments.

• Solid understanding of performance modeling, systems concepts, or interest in low-level metrics (e.g., latency, throughput, memory usage).

• Analytical mindset, with the ability to reason mathematically and think in terms of performance tradeoffs.

• Autonomous and proactive, with a passion for building robust and meaningful tools.

What we offer:

• A rewarding internship experience with a competitive stipend and benefits tailored to support you during your time with us.
• The opportunity to learn from top experts in AI and cloud computing, gaining hands-on experience and mentorship in a high-performing team.
• A culture that values curiosity, collaboration, and innovation, where your ideas are welcome and your contributions matter.
• Support for your personal and professional growth, with access to tools, guidance, and feedback to help you learn and improve every day.
• The potential to transition into a full-time role after your internship - we see this as the beginning of a longer journey together.
