Lead Product Manager - Physics-AI & Thermal-Mechanical Systems

Flexcompute Inc.
Watertown, MA Full Time
POSTED ON 4/1/2026
AVAILABLE BEFORE 6/1/2026

Flexcompute is the physics company. We scale first-principles physics into neural physics foundation models to redefine the boundaries of industrial simulation and design.

Our core technology features the world’s fastest GPU solvers, delivering orders-of-magnitude speedups over traditional tools. By integrating these solvers with our proprietary AI models, we enable engineers to explore design spaces that were previously computationally inaccessible. At Flexcompute, we don’t just make simulations faster; we make the “impossible” solvable, helping our partners tackle the most critical challenges in 3D-IC design, aerospace, and beyond.

  • The Domain Expert: You have a deep understanding of thermal and structural simulation (FEA/CFD). You know the limitations of the current status quo and are frustrated by how slow traditional tools are.
  • The Strategist: You have 5-10 years of experience in Product Management, ideally in CAE, EDA, or high-performance computing (HPC).
  • Technically Fearless: You hold a degree in Mechanical Engineering, Physics, or a related field. You are comfortable discussing GPU architectures, solver convergence, and neural network latencies with PhD-level researchers.
  • Future-Oriented: You believe that the future of engineering is AI-accelerated and are eager to build the platform that makes that a reality.

The Role

  • Market Discovery: Identify and prioritize high-impact use cases for our thermal-mechanical solvers. You will look beyond 3D-ICs to thermal management in data centers, electric drivetrains, and satellite systems.
  • Product Roadmap: Own the product lifecycle from inception to launch. You will define the features, UI/UX requirements, and API capabilities that allow engineers to harness the world’s fastest solver seamlessly.
  • AI Product Strategy: Define how our Physics AI Foundation Models translate into tangible value for end-users. How does an engineer interact with a “neural” simulation? You will answer that question.
  • Strategic Partnerships: Collaborate with industry leaders to pilot new technologies, ensuring our product solves real-world pain points like package warpage, thermal-mechanical fatigue, and high-flux cooling.
  • Competitive Moat: Position Flexcompute against legacy incumbents by highlighting our advantage in speed, accuracy and scale,  and our unique ability to scale first-principles physics into AI.

  • Competitive compensation with equity of a fast-growing startup.
  • Medical, dental, and vision health insurance.
  • 401(k) Contribution.
  • Gym allowance.
  • Friendly, thoughtful, and intelligent coworkers.
