Job ID: 1702
The Role:We're looking for exceptional early-career engineers to grow with us. As an Associate Firmware Engineer, you'll work alongside world-class physicists and hardware engineers to build embedded software for next-generation quantum sensing instruments. This is a hands-on, high-impact role where your code directly enables precision measurement at the frontier of quantum technology.
If you've just completed a degree from a top engineering program and want to do work that matters, not CRUD apps, but real-time control systems running inside instruments that measure the universe, this is your role.
Responsibilities:
- Write and verify embedded firmware for ST microcontrollers, including COTS devices and MCUs integrated into custom ASICs
- Implement control algorithms critical to the operation of high-precision quantum sensing instruments
- Develop peripheral drivers for mixed-signal devices, working directly from electronic schematics
- Partner with hardware engineers on board testing and bring-up activities
- Contribute to a rigorous engineering culture through code reviews, GitHub task tickets, and retrospectives
- Clearly document and communicate your work in a highly collaborative, cross-disciplinary environment
Requirements:- Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or Computer Science from an accredited program, we're targeting graduates from highly rated programs with strong fundamentals
- Demonstrated ability to write production-quality C/C++ for small embedded processors
- Experience writing interrupt service routines, peripheral drivers, and multi-threaded firmware using RTOSs and/or bare-metal environments
- Scripting experience in Python, Perl, or similar languages
- Hands-on experience with lab test equipment (oscilloscopes, function generators, voltmeters)
- Strong debugging instincts, able to isolate and resolve bugs using debuggers and simulation tools
- Comfort working in a laboratory setting
Preferred Qualifications:- Experience designing PID or other control algorithms
- Familiarity with fixed-point arithmetic and digital filter design
- Experience with communication protocols: TCP, UDP, UART, SPI, I2C, or similar
- Assembly language programming for embedded targets
- Experience with lightweight Ethernet stacks (e.g., lwIP)
- Background with SoC or FPGA devices

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying "U.S. Person" (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
