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
To comply with the US export control laws, Vector Atomic employees must be U.S. citizens (born or naturalized), lawful U.S. permanent residents (i.e. green card holders), and certain categories of refugees, and asylees.

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

**Benefits will be provided by Vector Atomic, an IonQ Company, and will differ from the benefits listed on the IonQ website.**

The total compensation package includes base, bonus, equity and benefits. It's atypical to be hired at the top end of this range for the role, as actual pay is based on several factors, including job-related knowledge, skills, and experience.

If this role has a commission structure, the compensation range below just reflects the base compensation range.

Wage Transparency:

$107,458—$154,089 USD

Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity. Posted base salary figures are subject to change as new market data becomes available. Our benefits include comprehensive medical, dental, and vision plans, matching 401(k), unlimited PTO and paid holidays, parental/adoption leave, legal insurance, and a home technology stipend.

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.

US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. 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.
