Full Job Description

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 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

Requirements

Qualifications: Education & Experience

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.

We highly value

Excellent verbal and written communication skills, with the ability to effectively share information with both technical and non-technical audiences
Strong collaboration and engagement skills, with a sense of ownership, pride in your work, and a constant drive for success
A strong sense of urgency and responsibility, paired with attention to detail where it matters most
An open communication style and a positive, professional attitude reflected in daily work habits
Strong problem-solving skills and the ability to learn quickly in new domains
The ability to work with a high degree of autonomy—taking high-level goals and defining, resourcing, and executing an effective plan—while also collaborating closely and incorporating feedback from teammates as needed

Benefits

Salary range: $106,000 to $145,000

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
Equity Program
