PhD in Physics, Math or Computer Science, with a focus on quantum information theory or quantum computation will be preferred. * Experience with quantum algorithms and compiling in the regime of fault tolerant gates preferred. * Experience working with partners in academia or industry to analyze real-world quantum applications of interest preferred. * Proven team player with an ability to work effectively across departments, sites and time zones. * Ability to work independently and contribute to fast-moving start-up environment. * Experience programming in Python, C++ or similar languages. ## Description Within the Quantum Algorithms team, we develop and adapt quantum algorithms, identify and scope promising use cases, and analyze their resource requirements. In this role, you will translate computational tasks into abstract quantum-algorithm specifications, analyze their asymptotic performance, and define meaningful problem instances that lie beyond the practical reach of classical computation. You will also work closely with PsiQuantum's Compilation team to develop explicit implementations of these algorithms and evaluate their resource requirements on our architecture. In this position, you will be expected not only to conduct outstanding individual research, but also to formulate and lead broader research programs that draw on the work of other researchers and collaborators. You will contribute to cross-team initiatives spanning PsiQuantum's applications, architecture, and compilation efforts, helping to connect algorithm design with the practical requirements of fault-tolerant quantum computation. The role will also involve external collaboration. You will have the opportunity to lead projects with industrial and research partners, working with domain experts to identify important computational challenges, formulate them as well-defined problems, and map them to appropriate quantum algorithms. Success in this work requires the ability to communicate across disciplinary boundaries and to move fluently between real-world applications, mathematical abstractions, algorithmic complexity, and implementation-level resource analysis. The ideal candidate combines deep technical expertise with scientific leadership, intellectual independence, and a collaborative mindset. They will be comfortable shaping open-ended research directions, assessing the practical significance of algorithmic advances, and guiding projects from the initial identification of an application through to a concrete fault-tolerant quantum algorithm and a detailed resource estimate., * Propose initiatives into research and development of quantum algorithms tailored for fault-tolerant quantum computers; act as primary contributor to research programs beyond the current state of the art in quantum algorithms design. * Work closely with external partners to instantiate, validate and optimize quantum algorithms for use cases across a variety of domains, such as life sciences, industry and sustainability. * Establish families of benchmarks and problem instances to validate post-classicality of quantum algorithms. * Guide both the simulation and analysis of resource requirements for fault tolerant implementation of quantum algorithms in photonic quantum computing. ## Related Videos - [Quantum Computing - How Does It Work, How Will it Affect Us and When?](https://www.wearedevelopers.com/videos/100293-quantum-computing-how-does-it-work-how-will-it-affect-us-and-when) - [System Resilience: Surviving the Software Storm](https://www.wearedevelopers.com/videos/874-system-resilience-surviving-the-software-storm) - [How Regex Works: The Secret Sauce Behind Pattern Matching](https://www.wearedevelopers.com/videos/1212-how-regex-works-the-secret-sauce-behind-pattern-matching) - [Quantum DevOps - Quantum Application Development](https://www.wearedevelopers.com/videos/1441-quantum-devops-quantum-application-development) - [Quantum Computing - The tiny and the big challenges](https://www.wearedevelopers.com/videos/934-quantum-computing-the-tiny-and-the-big-challenges) - [Quantum computing for developers: Solving optimization problems with Qiskit](https://www.wearedevelopers.com/videos/777-quantum-computing-for-developers-solving-optimization-problems-with-qiskit) ## Related Articles - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [The Fastest-Growing Tech Sectors to Look Out for in 2025](https://www.wearedevelopers.com/magazine/373-the-fastest-growing-tech-sectors-to-look-out-for-in-2025) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
