We are looking for a Senior Full Stack Software Engineer for Application Engineering . As a Software Engineer on the Applications Engineer team you'll be part of a cross-functional team whose mission is to deliver real-world applications and deliver value from the jump forward in computing that quantum solving represents. We don't just build the world's best quantum computers - we apply cutting-edge quantum tools to real-world problems. Until this year our team for Applications Research has been building prototypes and doing research by working closely with our customers. Our new department Applications Engineering transforms those prototypes and research into applications for broad use. Our work makes those innovations available to more people and businesses as libraries as APIs and ultimately as whole SaaS applications. Our Application Engineering team has a commitment to engaging user experience and showing quantum advantage not just talking about it. We are especially focused on clearly communicating the value of hybrid computing and making clear outputs to visualize domain specific problems. It’s a chance to shape how quantum computing is conceptualized in contrast to classical computing To support that goal and lay the groundwork for future quantum-enhanced services this role will also help polish our internal tools APIs and integrations. Along with humans other digital tools and systems will need to easily read and parse the solutions we generate. That means designing APIs and library interfaces often in domain specific terms or formats to speak to experts in tools and systems they already know deeply. You will be a key contributor in taking novel quantum approaches to cutting-edge problems and turning them into clear concise tools. You will help shape how everyday developers visualize and use quantum computing to solve problems in close collaboration with Developer Tools Infrastructure and Product teams.
will be excited about working on a chemistry simplification via Quantum Computing tool one month and working on visualizing novel topology solver the next.
Creating simple and clear interfaces in cooperation with domain experts. We bridge quantum computing to specific domain by creating clear API interfaces in the language and visuals domain experts are experts in. Designing the API endpoints and intuitive software library interfaces making applications and tools easy to maintain and update Working closely with peers in Applications Developer Tools and Field Engineering teams to share best practices and give feedback on internal tools especially rich data API’s to support large data sets and where applicable visualization Mentoring junior developers with the team.
