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.

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 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.

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 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 work do theoretical physicists do?

Theoretical physicists develop mathematical models and theories to understand fundamental physical phenomena, such as particles, forces, and the universe's structure. They often work with complex equations, computer simulations, and collaborate with experimental physicists to test their hypotheses, typically working in research institutions or academia.

Job description

Company Overview

Pronoia Energy is a pioneering deep tech startup at the forefront of quantum energy storage innovation. As a lean, mission-driven team, we thrive on rapid prototyping, cross-disciplinary collaboration and solving complex engineering challenges to turn quantum physics into practical, scalable products. Our current focus is on developing our groundbreaking room-temperature macroscopic quantum energy storage technology that promises orders of magnitude greater energy density, faster charging, and higher power delivery as well as being cheaper and safer compared to existing battery technology. This represents a paradigm shift in energy storage with applications spanning consumer electronics, electric vehicles, renewable grids, and beyond.


Role Summary

To meet our ambitious goals we are hiring a Theoretical Physicist to provide additional layers of validation for our innovative inventions. This will be an early scientist in our most fundamental research function, working directly with the co-founders. In this role, you will develop the theoretical foundation of our quantum-energy approach and derive what our experiments should show, identifying which directions are promising versus dead ends, and give the company a principled map of its upcoming frontier. You will partner directly with the co-founder leading Research and Science and translate deep theory into experimental direction the rest of the team can act on. This role is onsite in Torrance, California.


Key Responsibilities

  • Develop and refine the theoretical foundations of our quantum-energy-storage approach.

  • Derive testable predictions and translate deep theory into concrete experimental direction.

  • Distinguish real, robust effects from fragile or artifactual ones, keeping the science honest.

  • Partner directly with the founders leading Research and Science.

  • Help set the company's scientific roadmap and priorities.


Required Qualifications

  • A physics PhD with genuine theoretical depth in a relevant subfield, such as quantum thermodynamics, condensed-matter theory, quantum optics, or statistical mechanics.

  • Published works, intellectual honesty and deep humility.

  • A self-starter who thrives amid ambiguity and rapid iteration with the ability to turn theory into direction the rest of the team can act on.


Preferred Qualifications

  • Research experience directly relevant to quantum batteries, superlattices, or solid-state energy storage.

  • Standing relationships in the academic quantum-thermodynamics or condensed-matter communities.

  • Experience translating theory into experimental programs.

  • Prior work bridging academia and a company or national lab.


What We Offer

  • Chance to solve one of the world's biggest engineering challenges and pioneer quantum energy storage.

  • The opportunity to be the founding scientist of a new field's company, with real ownership and direct partnership with a founder.

  • Competitive salary, equity in a transformative startup, and performance-based incentives.

  • Access to cutting-edge labs, tools, and resources in a flexible, collaborative work environment.

  • Comprehensive benefits: health insurance, unlimited PTO, professional development stipend, and relocation assistance if needed.
