Quandela is committed to making quantum computing accessible to all in order to address the most complex industrial and societal challenges. Learn more at: Quandela | Leading Photonic Quantum Computing Solutions Description of the Project As a Quantum Applications Engineer , you will work at the intersection of quantum algorithms, real-world applications and customer projects . Your mission will be to identify relevant problems that can be addressed using Quandela's quantum computing technology, assess their feasibility and define how meaningful performance should be measured. Working directly with industrial and academic partners, you will translate real-world challenges into quantum computing problems, evaluate potential approaches and establish the appropriate benchmarks against classical methods. This is a highly technical role with strong exposure to customers and partners. It is particularly suited to someone with a background in quantum algorithms who wants to apply that expertise to practical use cases rather than focus exclusively on theoretical research. Your Key Responsibilities Identify and assess quantum use cases by working with customers, industrial partners and internal teams to understand their challenges and translate them into relevant computational problems. Perform feasibility studies to determine whether and how these problems can be addressed using current and near-term quantum computing technologies, with a particular focus on NISQ approaches. Define meaningful benchmarks , including relevant problem instances, expected outputs, accuracy targets and classical baselines to objectively evaluate quantum approaches. Explore promising application domains and contribute to application roadmaps, from near-term demonstrations to longer-term utility-scale applications. Evaluate scientific, industrial and economic value to help prioritize the applications where quantum computing can have the greatest impact. Design and maintain strategic demonstrations and Proofs of Concept , working with internal teams or external software partners depending on the project. Follow customer projects throughout their lifecycle , including projects where algorithm development is performed by external partners. Present technical work to customers and partners , explaining quantum approaches, results, limitations and opportunities to both technical and non-specialist audiences. Collaborate closely with Quandela's algorithm, machine learning, product, project management, sales and engineering teams. Depending on the strategic interest of a project, you may also contribute directly to the development and implementation of quantum algorithms in Python. What will make you successful You do not need to know every possible quantum application from day one. What matters is your ability to approach an unfamiliar problem, ask the right questions, understand its computational structure and determine whether quantum computing provides an interesting direction to explore. You are comfortable navigating between research and practical applications : scientifically rigorous enough to challenge an algorithmic approach, pragmatic enough to assess its real-world relevance, and comfortable enough with people to discuss your conclusions directly with customers. Requirements You have a strong technical background
