Senior Quantum Software Engineer information

What is the difference between Senior Quantum Software Engineer vs Quantum Software Developer?

AspectSenior Quantum Software EngineerQuantum Software Developer
Required CredentialsBachelor's/Master's/PhD in Computer Science, Physics, or related field; experience with quantum algorithmsBachelor's or higher in relevant field; familiarity with quantum programming languages
Work EnvironmentResearch labs, tech companies, academia; often involved in project leadershipStartups, tech firms, research teams; focused on coding and implementation
Industry UsageUsed across quantum computing, research, and development sectorsPrimarily in software development teams within quantum tech companies

The main difference is that a Senior Quantum Software Engineer typically has more experience, leadership responsibilities, and a broader understanding of quantum algorithms, while a Quantum Software Developer focuses on coding and implementing quantum programs. Both roles require strong technical skills, but the senior role often involves guiding projects and strategy.

Job description

About the role

As a Software Engineer on the Boulder Opal team, you will build the backend infrastructure that supports our quantum software platform. You'll work alongside compiler engineers and researchers to develop scalable backend systems, APIs and performance‑critical services while growing your understanding of compiler technologies and quantum computing.

This role is ideal for a strong backend engineer interested in systems programming who wants to develop expertise in compiler engineering over time.

What you’ll be doing:

  • Design, build and maintain scalable backend services in Python and C++.
  • Develop APIs and backend services supporting our compiler and quantum runtime.
  • Build reliable distributed systems and cloud‑native services.
  • Improve performance, reliability and observability across backend components.
  • Collaborate with compiler engineers to integrate new compiler capabilities into production systems.
  • Work with researchers and product teams to deliver new platform capabilities.
  • Learn and contribute to compiler infrastructure as your expertise grows.

Ideally, you’ll have:

  • Bachelor's degree in Computer Science, Engineering or related discipline.
  • Strong programming skills in Python.
  • Experience with modern C++.
  • Experience building backend systems or distributed services.
  • Experience designing APIs using REST, gRPC or GraphQL.

It would be fantastic (but not essential) if you bring:

  • Experience building high‑performance backend systems.
  • Experience with asynchronous programming and concurrency.
  • Experience with FastAPI, Flask or Django.
  • Familiarity with compiler concepts or programming language implementation.
  • Exposure to LLVM or MLIR.
  • Interest in quantum computing or scientific software.
  • Experience with Rust, Go, or other systems programming languages.

Salary

The targeted base salary range for this position is between $130,000 - $170,000 and will ultimately be determined by specific job‑related skills, experience, level, location and other contributing factors. Depending on the position offered, this role may be eligible for annual discretionary bonuses, equity and other forms of compensation outside of the targeted base salary range.

Qualified applications with arrest or conviction records will be considered for employment in accordance with the Los Angeles County Fair Chance Ordinance for Employers and the California Fair Chance Act.
