About IonQ:

The Role:

We are looking for a Staff 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.

The ideal candidate will be excited about working on a chemistry simplification via Quantum Computing tool one month, and working on visualizing novel topology solver the next.

Responsibilities:

  • 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.

Requirements:

  • Bachelor's degree in Computer Science, Engineering, Physics, or a related field, or equivalent training, fellowship, or work experience
  • 8+ years of experience as a full stack developer, preferably in backends based on JavaScript, Python, Golang
  • 8+ years of experience in REST, GraphQL, or gRPC frameworks for robust data delivery
  • Previous work in scientific computing, quantum computing, or a technical consulting fields
  • Experience building or supporting rich UIs, especially with data visualization tools like three.js, D3, WebGL
  • A track record of shipping applications that solve real business problems
  • Familiarity with Agentic AI coding tools and techniques such as skills, docstring generation, code review, and best practices for AI coding

Preferred Qualifications:

  • 10+ years of experience as a full stack developer, preferably in Python or Golang as a backend language,
  • 5+ years frontend experience in Three.js, D3 or WebGL, for heavier visualization. Previous work in quantum computing, quantum algorithms, or a degree in quantum physics
  • Experience in scientific computing, especially in numpy, pandas, or in C/C++
  • Experience packaging backend API’s and UI into containerized solutions for deployment to cloud services such as AWS, GCP, etc.
