• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related technical field.
• 8+ years of experience in architectural modeling or simulation platforms, preferably with experience in AI or high-performance computing projects.
• Strong understanding of system-level challenges in AI compute systems, including network bandwidth, memory, and thermal considerations.
• Proficiency in C and C++ for high-performance SW development and Python for handling machine learning workloads and related tasks
• Hands-on experience in performance analysis, profiling tools, and model validation techniques.
• Strong analytical and problem-solving skills, with a focus on identifying and solving complex system-level challenges.
• Excellent collaboration and communication skills to work effectively across hardware, software, and systems teams
  
• Provide technical leadership and mentorship to junior software engineers.
• Entrepreneurial mindset, adaptable to fast-paced, dynamic environments.

Bonus Points:

• Experience in AI hardware or deep learning workloads.
• Familiarity with performance modeling tools, simulators, or architectural exploration platforms.
• Experience in start-up environments or working with early-stage technologies.

What we offer:

• A competitive salary and benefits package, tailored to recognize your dedication and contributions.
• The opportunity to collaborate with leading experts in AI and cloud computing, learning from the best and the brightest, fostering continuous growth.
• An environment that values innovation, collaboration, and mutual respect.
