Software Engineer

Software Engineer

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 Software Engineer with deep expertise in Rust and familiarity with embedded systems development to join our cross-functional engineering team. In this role, you'll work across the stack—from low-level embedded Rust and gateware integration to higher-level Rust application interfaces, with exposure to frontend technologies. You'll collaborate closely with hardware, firmware, and application teams to build reliable, high-performance systems.

While a physics background is not required, experience working with physical systems or scientific instrumentation is beneficial. The ideal candidate is fundamentally a software engineer, with strong embedded systems intuition and a commitment to continually deepening their technical expertise.

Job Responsibilities

The duties and responsibilities listed below describe the essential functions of the role. Actual responsibilities may vary based on business needs and may change or expand over time.

• Collaborate closely with cross-functional teams—including hardware engineers, physicists, and software developers—to deliver fully integrated product solutions.
• Maintain documentation of designs, workflows, and processes in compliance with internal and regulatory standards.
• Contribute to integrating Rust-based middleware and driver software used for device control.
• Collaborate with hardware and FPGA teams to develop software drivers and interfaces for embedded devices.
• Develop and maintain system-level APIs and communication layers
• Contribute to frontend development where needed to support tooling, visualization, or user interfaces
• Write clean, well-tested, and well-documented code
• Participate in code reviews and technical design discussions
