Infleqtion is hiring a Software Engineer

About the Role

Infleqtion is seeking a Software Engineer with deep expertise in Rust and familiarity with embedded systems to join our cross-functional engineering team. You will work across the entire technology stack—from low-level embedded Rust and gateware integration to higher-level Rust application interfaces and frontend technologies—collaborating closely with hardware, firmware, and application teams to build reliable, high-performance systems.

What You'll Do

  • 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.

What We're Looking For

  • Bachelor’s degree in computer science, Electrical or Computer Engineering, or a related technical discipline (or equivalent practical experience).
  • Minimum of 5 years of industry experience in Rust Development.
  • Exposure to embedded software development using Rust and/or C++.
  • Working knowledge of gateware development and hardware/software integration (e.g., FPGA-based systems).
  • Exposure to frontend development (e.g., JavaScript/TypeScript, React, or similar frameworks).
  • Strong background in developing and debugging embedded Linux environments.
  • Familiarity with embedded and system-level communication interfaces (SPI, I²C, UART, PCIe, Ethernet, etc.).
  • Solid understanding of systems programming concepts (memory safety, concurrency, performance).

Nice to Have

  • Background in high-reliability or performance-critical systems.
  • Knowledge of WebAssembly (WASM) and Rust-based frontend frameworks.
  • Familiarity with real-time operating systems (RTOS) and bare-metal development.
  • Demonstrated experience in architecting embedded control systems and integrating them into hardware platforms.

Technical Stack

  • Rust, C++, JavaScript/TypeScript, React
  • FPGA, Embedded Linux
  • SPI, I²C, UART, PCIe, Ethernet
  • WebAssembly (WASM), RTOS

Team & Environment

You will be part of a cross-functional engineering team, working directly with hardware, firmware, and application developers.

Benefits & Compensation

  • Compensation: $120,000 to $145,000 + equity via our Equity Program.
  • 100% company-paid medical, dental, vision, short/long-term disability.
  • Employer-funded Health Savings Account.
  • Unlimited PTO.
  • 401(k) match.
  • Company-paid Life and AD&D Insurance.
  • Flexible Savings Account.
  • Paid FMLA, Maternity/Paternity Leave.
  • Employee Assistance Program.
  • Student Loan Repayment.

Infleqtion is an equal opportunity employer.
