Does NASA hire theoretical physicists?

NASA employs theoretical physicists in research roles related to astrophysics, space science, and fundamental physics, often requiring advanced degrees such as a Ph.D. and strong analytical skills. These positions may involve developing models, simulations, and contributing to scientific missions, typically within research or engineering teams. Candidates should have expertise in physics, mathematics, and relevant programming tools.

What are the key skills and qualifications needed to thrive as a theoretical physicist?

Excelling as a Theoretical Physicist requires advanced expertise in physics and mathematics, typically supported by a Ph.D. in physics or a closely related field. Familiarity with computational modeling tools (such as MATLAB or Mathematica), programming languages (like Python or C++), and scientific publication systems is common. Critical thinking, problem-solving, and the ability to communicate complex ideas clearly are valuable soft skills in this role. These abilities allow Theoretical Physicists to develop and test new theories, contribute to innovative research, and effectively share their findings with the scientific community.

What jobs can a theoretical physicist get?

A theoretical physicist can work in academia as a researcher or professor, in government laboratories conducting fundamental research, or in industry roles such as data analysis, software development, or technology consulting. They often utilize strong analytical, mathematical, and programming skills, and may require advanced degrees like a Ph.D. to qualify for research positions.

What does a typical workday look like for a theoretical physicist?

A typical day for a Theoretical Physicist often involves formulating and refining mathematical models, running computer simulations, and analyzing data to explore physical phenomena. They may spend time collaborating with experimental physicists, attending research meetings, or reviewing scientific literature to stay current in their field. Writing and revising research papers, preparing for conferences, and mentoring graduate students or team members are also common activities. The work environment is usually a blend of independent research and teamwork within academic institutions, research centers, or government laboratories.

What work do theoretical physicists do?

Theoretical physicists develop mathematical models and use complex calculations to understand fundamental principles of the universe, such as the nature of matter, energy, space, and time. They often work in research institutions or academia, utilizing tools like computer simulations and advanced mathematics to test hypotheses and predict phenomena.

What does a theoretical physicist do?

A Theoretical Physicist studies the fundamental laws of nature by developing mathematical models and theories to explain physical phenomena. They work on abstract concepts such as quantum mechanics, relativity, and cosmology, often without direct experimentation. Their work can lead to new scientific discoveries, influence experimental research, and contribute to advancements in technology. Many Theoretical Physicists work in academia, research institutions, or industries like aerospace and computing.

Quantum Theorist, Atomic Physics Focus

Atom Computing

Boulder, CO • On-site

$160K - $185K/yr

Full-time

Re-posted yesterday

Job description

At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Join a talented team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing.

Atom Computing is seeking a Quantum Theorist to contribute to a variety of projects that help with the development of neutral atom quantum computing. In this role, you'll be working directly with other theorists and experimentalists to model our quantum computers, improve calibration routines, characterize machine performance, and propose methods for their overall advancement. You'll work within an expert team of atomic physics and quantum error correction theorists that shapes future system design and supports experimental progress. 

This role reports to the Quantum Theory Manager within Atom Computing’s Applications & Theory department. Applications will be considered for our Berkeley, CA or Boulder, CO office.

Job Responsibilities
  • Conduct independent and/or collaborative theoretical and computational projects that drive the understanding and development of neutral atom quantum computers.
  • Contribute to the development and operation of a variety of atomic physics simulations and translate them into high-quality, maintainable software solutions.
  • Collaborate with Experimentalists, Quantum Engineers, Error Correction Theorists, and AMO Theorists to model experimental results, develop noise models for quantum hardware, and contribute to the design of neutral-atom quantum computers.
  • Write clean, well-tested, and documented code in multiple languages (preferrably Python, Julia, or C++).
Experience & Education

  • PhD in Physics, Mathematics, Engineering, Computer Science or a related field.

Qualifications
  • Deep understanding of atomic, molecular and optical physics. Experience working with or modeling of Rydberg atoms is particularly appreciated.
  • Excellent written and oral communication skills, with published results within their field of research.
  • Technical expertise spanning atomic structure, quantum optics, and qubit control, e.g. using QutiP, QuantumOptics.jl, or equivalent.
  • Familiarity with modern software development practices: version control, unit testing, continuous integration, and documentation.
  • Temperamentally suited to work at a fast-growing startup: self-motivated, humble, driven, collaborative, with a high tolerance for ambiguity and uncertainty.

Atom Computing provides a wide variety of perks and benefits, including fully paid medical, dental, and vision insurance for our employees and their dependents. Additionally, unlimited paid time off, 401K company matching, short- and long-term disability, FSA, dependent care benefits, and life insurance.  We also offer drinks, snacks, and catered team lunches in our offices, every day!

The base salary range for this position is between $160,000 - $185,000, commensurate with experience. In addition to salary, we offer an annual bonus and equity in the company.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
