Senior Software Engineer: Numerical and High Performance Computing

Remote

Who We Are

We exist to unlock human potential.

Too often, AI drains it—drains budgets, drains energy resources, drains ownership of data. OpenTeams was founded to change that. We build AI that empowers. Our models are energy-efficient, cost-effective, and fully yours. 

Our ethos is open source. That means freedom, trust, and accountability are built into every line of code. We reinvest 3% of our profits back into the open-source community, because we believe tech is most powerful when it serves everyone.

At our core, we value freedom, teamwork, accountability, and uncompromising quality. If you want to fight Goliath, and shape tools that set people free, OpenTeams is the place to do it.

We’re looking for a highly motivated Software Engineer with a strong background in numerical computing, high-performance computing (HPC), or deep learning frameworks to join our PyTorch-focused engineering team. If you’re passionate about building performant systems, contributing to open source, and shaping the future of the Python AI ecosystem, this role is for you.

What You’ll Do

Have you seen the explosive growth of Python in data science and machine learning? Are you excited by the impact of tools like PyTorch, NumPy, Triton, Numba, and Dask? In this role, you’ll help advance that ecosystem by building features and performance improvements used by millions.

You will:

  • Develop, optimize, and maintain core components of PyTorch and related open-source libraries
  • Contribute directly to projects such as PyTorch, TorchRL, TorchAO, and Triton
  • Work across C++, CUDA, Python, C, and MLIR
  • Design and implement new features, performance enhancements, kernel optimizations, and infrastructure improvements
  • Debug complex numerical, performance, and scalability issues in large, production-level codebases
  • Engage with the broader PyTorch community, including maintainers, contributors, and users
  • Collaborate closely with internal engineering teams and client partners using PyTorch at scale
  • Participate in code reviews, architectural discussions, and team mentoring
  • Build your presence and impact within the Python and open-source communities

What We’re Looking For

You don’t need to be an expert in every PyTorch submodule — we care about strong fundamentals and the ability to learn quickly. If you have experience with large-scale systems and modern numerical or GPU computing, you’ll thrive here.

Strong candidates will have experience with:

  • C++ and Python in production environments
  • GPU programming (CUDA preferred)
  • High-performance or numerical computing
  • Working in large, complex codebases
  • Debugging low-level or performance-critical issues
  • Communicating clearly within engineering teams and open-source communities

Bonus experience (nice to have, not required):

  • PyTorch, NumPy, or other scientific Python libraries
  • Deep learning fundamentals or experience with training/inference systems
  • MLIR, Triton, or compiler-related tooling

We invest heavily in helping engineers grow within both OpenTeams and the Python open-source ecosystem. If you’re excited about advancing open-source AI infrastructure and collaborating with world-class maintainers, we’d love to talk.

Grow With Us

At OpenTeams, growth isn’t just about the company—it’s about you.

We believe the best careers are built at the edge of your potential. That is where new tools, ideas, and technologies change the world. Here, you’ll work alongside pioneers of AI, solving problems that matter: making AI more transparent, more ethical, and more empowering. 

Opportunities aren’t limited by geography. You’ll collaborate with global experts, contribute to open source projects that power the world’s technology, and stretch your skills daily.

We invest  in curiosity, creativity, and ownership. That means you’ll be trusted to take big swings, supported to learn fast, and celebrated for bold thinking.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
