Job description

POSITION SUMMARY

Infleqtion is a global quantum technology company solving the world’s most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products, Infleqtion enables “quantum everywhere” through our ecosystem of devices and platforms.

Infleqtion is seeking a Senior Embedded Systems Engineer to support the development and integration of advanced Quantum RF (QRF) sensing systems.

This role focuses on designing and implementing the gateware, software, and hardware to enable opto-electrical control systems for our quantum sensing solutions. In this role, you will work closely with a cross-functional team of software engineers, opto-mechanical engineers, and physicists to develop unique control algorithms and complex data processing tools. You will be part of a purpose-built team to bring quantum systems from lab environments to field demonstrations.

JOB RESPONSIBILITIES

The duties and responsibilities outlined below include essential functions of the role.

Design, develop, and maintain embedded software and gateware for control of QRF systems and subsystems
Key contributor towards developing control system architectures for future quantum sensors
Subsystem integration into quantum systems, including verification, validation, and debugging
Deploy high test coverage and fully leverage our CI pipelines and hardware test beds to have confidence that your designs will work as expected
Develop programmable logic and low-level CPU interfaces to control integrated systems and peripherals including quantum sensors, magnetic field controllers, and lasers

Create test scripts to validate subsystems and components of integrated systems
Support board bring-up and debugging efforts, providing feedback to design teams.
Work closely with electrical, mechanical, software, and physics teams to ensure successful system integration and deliver high-performance real time embedded systems
Support applications and demo teams by improving system usability and reliability
Operate and interface with a range of electrical and optical lab test equipment
Working with Rust firmware engineers to define architecture and drivers

EDUCATION AND EXPERIENCE

BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related field
4+ years of experience in embedded systems, FPGA development, or mixed signal design
Familiarity with one two following areas, proficiency in both areas preferred:
Embedded system development in Rust. If you have relevant expertise but with C/C++, you may still be successful in this role if you have interest in Rust and have some idea of how Rust can be used to rapidly develop safe and performant systems
FPGA development in any HDL with experience in RF synthesis. Whether you like to work in Verilog/VHDL or bleeding-edge languages like SpinalHDL, nMigen, or MyHDL
Experience interfacing with hardware (SPI, I2C, UART, Ethernet, etc.)
Strong debugging skills across hardware and software boundaries
Experience with common benchtop test equipment, such as oscilloscopes, spectrum analyzers, multimeters, and power supplies
This position may require access to information protected under U.S. export control laws and regulations, including the Export Administration Regulations (EAR) and the International Traffic in Arms Regulations (ITAR). Please note that any offer for employment may be conditioned on authorization to receive software or technology controlled under these U.S. export control laws and regulations without sponsorship for an export license

PREFERRED / NICE-TO-HAVE SKILLS

Experience with RF systems, signal generation, or data acquisition hardware
Familiarity with control systems or feedback loops
Experience with FPGA-based systems
Experience developing test or automation frameworks
Exposure to scientific instrumentation or R&D environments
Exposure to hardware design and schematic capture

TRAVEL

Up to 10% travel may be required.

WORKING CONDITIONS and PHYSICAL REQUIREMENTS

Work will normally be performed in an office and laboratory environment and around technical equipment including computers and lasers. Able to sit, stand, bend, lift and carry up to 40 pounds without assistance. Able to efficiently use automated office equipment such as laptops, copiers, and printers; able to effectively engage in communications (via phone, computer, or in-person). Any required Personal Protective Equipment will be provided and must be properly used in accordance with company requirements.
