Description

Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders-of-magnitude improvements in sensing and computing applications. As a deep-tech startup, we embrace a results-driven, fast-paced, and customer-focused approach to innovation.

We are seeking a Senior Software Engineer to lead the development and productization of our software systems that interface with cutting-edge quantum and embedded hardware. This role focuses on full-stack software engineering, team leadership, and the establishment of strong software engineering practices.

While a physics background is not required, familiarity with physical systems or scientific instrumentation will be helpful. The ideal candidate is a software engineer first, with strong embedded systems awareness and proven leadership in modern software development environments.

Role and responsibilities

  • Leadership & Coordination of global software development efforts for quantum sensing products
  • Serve as technical lead for the software engineering team, guiding day-to-day operations and development priorities.
  • Collaborate with project managers and technical leads to plan and execute development milestones.
  • Lead daily stand-up meetings, manage the Jira board, and ensure timely completion of sprint goals.
  • Oversee and enforce software engineering best practices, including code reviews, testing standards, documentation, and CI/CD processes.
  • Act as the liaison between the software engineering team and the broader multidisciplinary project team.
  • Software Development
  • Lead development of the frontend application built with React/Next.js, ensuring high performance, maintainability, and scalability.
  • Own the backend REST API written in Python (FastAPI), ensuring robust integration with hardware control and middleware layers.
  • Contribute to integration with Rust-based middleware and/or driver software used for device control.
  • Collaborate with embedded systems engineers to ensure seamless interaction between software and hardware components.
  • Participate in architecture discussions and contribute to technical design documentation.
  • Support the transition of projects from prototype to production-ready systems.

Requirements

  • Bachelor’s or Master’s degree in Computer Science, Software Engineering, or equivalent experience.
  • 4+ years of professional software engineering experience.
  • Expert-level proficiency in Python and JavaScript/TypeScript.
  • Strong experience with React and Next.js frontend frameworks.
  • Experience with FastAPI or similar modern Python web frameworks.
  • Familiarity with embedded software concepts (device drivers, low-level APIs, hardware communication protocols).
  • Demonstrated experience leading software development teams or acting as a technical lead.
  • Deep understanding of modern development workflows (Git, Jira, CI/CD pipelines, automated testing).

Desired Qualifications

  • Experience with Rust (especially in middleware or systems contexts).
  • Exposure to or interest in scientific instrumentation, hardware control, or physics-related systems.
  • Familiarity with Docker, Kubernetes, or other containerized deployment systems.
  • Experience in startups or R&D-focused environments.
