Introduction
At IBM Quantum, our mission is to bring useful quantum computing to the world. We deliver the industry’s most performant quantum systems and empower a global community to pioneer early use cases via Qiskit and the IBM software stack. Today, the IBM Quantum Network brings together over 275 Fortune 500 companies, national laboratories, academic institutions, and startups, all focused on a singular goal: extracting tangible value from quantum computers. As we execute an ambitious roadmap to demonstrate quantum advantage by the end of 2026 and deliver the first fault‑tolerant systems by 2029, we are looking for the innovators who will help us define this next era of computation.

Your Role And Responsibilities
As a Quantum Algorithm Engineer, you will sit at the intersection of high‑impact research, algorithm engineering, and strategic ecosystem growth. You will be responsible for driving research in quantum information science and applications,



with a dedicated focus on leveraging superconducting hardware and HPC integration to achieve demonstrable quantum advantage across a diverse range of domains such as high‑energy physics, chemistry, materials science, and optimization. This role requires a blend of scientific rigor and engineering excellence, as you will design and optimize quantum algorithms, perform system‑level performance modeling, and implement production‑ready software that facilitates reliable R&D; across the IBM Quantum stack.

Your work will be pivotal in bridging the gap between theoretical breakthroughs and real‑world utility for the general scientific community. You will lead high‑visibility technology demonstrations and partner with strategic clients in the IBM Quantum Network to execute research roadmaps – ensuring they achieve peer‑reviewed results through cutting‑edge techniques such as advanced error suppression and mitigation. Simultaneously, you will serve as a primary advocate for the user, identifying critical software gaps and del
