We are seeking a Quantum Compiler Engineer for our Broomfield, CO location.

Our compiler team is at the forefront of bridging the gap between groundbreaking quantum applications and the unparalleled computing power of quantum machines. As a Quantum Compiler Engineer, you are invited to join an interdisciplinary team of physicists and software developers dedicated to transforming platform agnostic quantum algorithms into concrete, executable instructions tailored for our state-of-the-art trapped-ion quantum computers.

In this role, you will engage in pioneering work, collaborating closely with compiler specialists to forge user-friendly languages and tools designed for crafting quantum programs. Your expertise will be instrumental in advancing the development of sophisticated heuristics and algorithms. These innovations are critical for optimizing the routing of ions across complex topologies, significantly enhancing the speed and efficiency of quantum applications executed on our platforms.

By contributing to our team, you will not only play a key role in optimizing code generation for quantum computing but also in shaping the future of quantum technology. Your work will ensure that our quantum computers can realize their full potential, unlocking new possibilities for solving some of the world's most challenging problems.
