Profile match
Flexcompute is a computer-aided engineering (CAE) and deep-tech simulation software company. Headquartered in Watertown, Massachusetts (in the Greater Boston area), and spun out by researchers from MIT and Stanford, the company develops high-performance physics simulation engines that accelerate hardware R&D across aerospace, defense, automotive, photonics, and semiconductor sectors.
Backed by Coatue

Flexcompute is a cutting-edge technology startup that specializes in ultra-fast simulation technology. Our products are utilized by companies in designing and optimizing technology products, with applications ranging from designing airplanes and cars to wind turbines and quantum computing chips. Our customer base includes both household names and startups in emerging industries. Our company was founded by world-renowned leaders in simulation technology from Stanford University and MIT. Backed by top VC firms, we are poised to disrupt the billion-dollar engineering simulation industry with our fast-growing trajectory

The program, running from 2024 through 2026, is designed to enlist ten exceptional recent graduates from the fields of Engineering, Physics, Mathematics, or Computer Science. These recruits will grow into the core part of our technical team, driving our company's growth into the 2030s. You will be paired with a senior technical staff member who will serve as your mentor. Working closely with one of the best engineers and scientists in the world of scientific computing, you will learn and grow quickly. From day one, you will work on challenging technical problems, from analyzing stubborn divergence to untangling complex system coupling, from streamlining workflow to optimizing GPU efficiency, from multi-physics to multi-scale. These challenges are not suitable for everyone. But if you are ambitious, motivated, and prepared to make a significant impact in the field of scientific computing, you will find them immensely rewarding.

Immediate Responsibilities:

  • Physics computing: Develop algorithms and software for physics simulation in electromagnetics, photonics, fluid dynamics, thermal and structural analysis.
  • Infrastructure computing: Develop algorithms and software to deliver exceptional computing experiences. This includes optimizing efficiency of GPU computing systems, management and visualization of high-volume large-scale scientific data, geometry handling and computing, AI for scientific computing, and next-generation workflow optimization.

Growth Trajectory in 3 years:

  • Respected experts in computational electromagnetics, fluid dynamics, thermal and structural analysis.
  • Senior frontend or backend developers.
  • Elite HPC specialists.
  • Emerging software architects.
  • Dynamic engineering managers.
  • Creative product managers.
  • Persuasive marketers.
  • Result-driven technical sales.

Requirements

Required Qualifications:

  • Recent graduate or graduating students in Engineering, Physics, Math, or Computer Science.
  • Exceptional programming skills in C++. (The lack of C++ skills can be offset by a proven record of extensive contribution to open source projects in other programming languages.)

Preferred:

  • Strong background in Electromagnetics, Photonics, Computational Geometry, Fluid Mechanics, Structural Mechanics, Aeroacoustics, Conjugate Heat Transfer, or adjacent fields.
  • Familiarity with numerical methods for solving large scale partial differential equations.
  • Master degree or PhD in an applicable technical field with 0-3 years of industry experience.
  • Familiarity with version control systems such as git and the Linux command line.
  • Familiarity with MPI, OpenMP, CUDA.

Join our "Rising Stars in Scientific Computing" program and seize the unique opportunity to work with leading experts in the field of scientific computing. Be part of a company that is pushing the boundaries of innovation. Apply today!
