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 world-class team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing.

Atom Computing is looking for a Senior Software Engineer to implement the quantum computing platform. In this role, you'll work across the full stack to deliver the platforms and applications that give our customers access to our quantum computers, while accelerating the development of our next-generation systems. Your work will span quantum job compilation, quantum error correction, instrument calibration, and experimental data management — touching the layers of the stack where physics meets production software. You'll collaborate closely with a talented, tight-knit team of engineers and physicists, reporting to the Software Engineering Manager. This is a rare opportunity to work at the intersection of deep science and engineering.

Candidates will also be considered for Atom's location in Boulder, CO and Austin, TX.  Under exceptional circumstances we may allow the position to be fully remote.

Responsibilities
  • Develop and maintain public API features and open-source SDKs for running customer-provided jobs on our quantum hardware and simulators.
  • Develop and maintain infrastructure for automating system tuning and calibration.
  • Develop and maintain software for scheduling the execution and analyzing the results of quantum algorithms.
  • Work closely with our Quantum Engineers to write idiomatic, tested and extensible code for executing experiments and algorithms on our quantum hardware.
Experience & Education
  • BS or MS in Computer Science, Computer Engineering, or equivalent.
  • Minimum 5 years of post-degree professional experience as a software engineer. 
Qualifications
  • A passion for writing software and a track record of implementing architecture level features in complex computer systems.
  • Proficiency with Python and SQL. Experience with a compiled language such as C++ or Rust is preferred. 
  • Familiarity with Git version control, automated testing, and software development best practices.
  • Willingness to learn atomic, optical, laser physics, and quantum mechanics concepts required to put work in context.
  • Experience with Azure, AWS and Terraform, Javascript, UI/UX design for webapps, and a background in physics are welcome, but not required.

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 $140,000 - $185,000, commensurate with experience. In addition to salary, we offer an annual bonus and equity in the company.
