The Role

As a Technical Lead for Real-Time Control Systems, you will provide the architectural vision and technical leadership necessary to build next-generation quantum instruments. You will be responsible for designing complex embedded systems on ARM SoC and ST Micro platforms, developing robust data acquisition pipelines, and implementing the control algorithms that drive precision sensing technology. This role sits at the intersection of hardware and software, requiring you to bridge the gap between physicists, electronics engineers, and firmware teams. Beyond writing production-quality code, you will serve as a mentor and strategist, driving coding standards, hardware bring-up strategies, and the continuous improvement of development infrastructure to ensure the scalability of quantum control frameworks.

Responsibilities

  • Technical Leadership: Provide architectural direction for real-time control systems and lead technical discussions across hardware and firmware teams.
  • System Architecture: Design system controllers on ARM SoC, including user-space drivers, libraries, and reusable frameworks for quantum system control.
  • Software Development: Write high-performance, production-quality code in C/C++ and Rust, establishing team-wide best practices and coding standards.
  • Control Theory & Implementation: Define and implement essential control algorithms, including robust control loops with reliable error handling for precision instruments.
  • Hardware Collaboration: Lead board testing and hardware bring-up strategies in coordination with hardware engineers.
  • Mentorship: Guide junior and senior engineers through code reviews, pair programming, and proactive technical coaching.
  • Process Improvement: Drive the evolution of development processes, tooling, and infrastructure, including CI/CD and automated testing.
  • Strategic Representation: Act as the primary technical voice for the team during cross-functional reviews and strategic planning sessions.

  • BS/MS in EE, CE, or CS with 8–12 years of experience, or a PhD with 8+ years of related work experience.
  • 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.
  • Embedded Expertise: Demonstrated mastery of complex embedded system architecture and designing software systems from the ground up.
  • Systems Programming: Deep understanding of hardware-software interfaces (TCP, UART, MMAP) and low-level system programming.
  • Technical Problem Solving: Strong debugging and troubleshooting skills using profilers, debuggers, and simulation tools.
  • Leadership: Proven ability to lead technical initiatives and influence engineering decisions across multi-disciplinary teams.
  • Communication: Excellent verbal and written skills for articulating complex concepts to diverse audiences.
  • Environment: Must be comfortable working in a laboratory setting.

Preferred Qualifications

  • Rust Proficiency: Extensive experience developing production Rust systems, including async runtimes, concurrency patterns, and performance optimization.
  • C++ Hybrid: Experience with embedded Linux alongside a strong understanding of C/C++ systems programming.
  • Advanced Control Theory: Expert-level knowledge of PID, state-space controllers, and adaptive control algorithms.
  • DSP & Algorithms: Experience with fixed-point algorithms, digital signal processing (DSP), and digital filter design.
  • Hardware-Software Co-design: Strong background working with SoC/FPGA devices and Linux kernel/device driver development.
  • Tooling & Scripting: Proficiency in Python for scientific libraries and developer tool creation.
  • Lab Equipment Mastery: Hands-on experience using oscilloscopes, function generators, and voltmeters to verify code performance.
  • DevOps for Embedded: Familiarity with CI/CD pipelines and automated testing frameworks tailored for hardware/firmware.

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.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
