The Role

Vector Atomic is building next‑generation quantum devices designed for real‑world applications, including GPS‑free navigation, high‑precision timing, geophysical exploration, and telecommunications. As a Senior Rust Software Engineer, you will serve as a technical leader within a rapidly growing, collaborative team of over 50 professionals delivering practical, transformative quantum technologies. In this high‑impact role, you will architect and write production‑quality Rust code, driving the software strategy for our advanced quantum instruments. You will collaborate deeply across disciplines with physicists, electronics engineers, and firmware engineers, taking ownership of system controllers, data acquisition pipelines, and critical control algorithms on ARM SoCs from concept to deployment.

Responsibilities

• Lead the design and development of reliable, high‑performance, production‑quality software architectures in Rust.
• Architect and verify system controllers on ARM SoCs, designing robust user‑space drivers for complex peripherals (including mixed‑signal devices) and low‑latency data acquisition pipelines.
• Implement and optimize critical control loops and precision algorithms essential to the stability and operation of quantum sensing instruments.
• Partner closely with hardware teams to lead board testing, hardware bring‑up, and the implementation of fault‑tolerant error‑handling systems.
• Oversee the development and scaling of core software libraries used for the control and automation of next‑generation quantum systems.
• Champion continuous improvement within the development process—leading technical code reviews, project retrospectives, and mentoring junior engineers.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, with 6+ years of professional software engineering experience (with a proven track record in embedded or hardware‑adjacent environments).
• Must be a U.S. citizen, lawful permanent resident, or eligible refugee/​asylee as required by U.S. export controls.
• Fully comfortable working hands‑on in a laboratory environment alongside physical hardware and complex test setups.
• Exceptional communication and collaboration skills, with the ability to bridge technical gaps between hardware engineers, software teams, and physicists.

Preferred Qualifications

• Extensive background coding in C/C++ or utilizing Python and its scientific libraries for data analysis and modeling.
• Deep expertise in designing, modeling, and coding advanced control algorithms (such as PID loops) and fixed‑point digital filters.
• Advanced experience interfacing with external hardware devices through protocols like TCP/UDP, UART, SPI, and I²C.
• Comprehensive background working with SoC/FPGA architectures and developing specialized Linux device drivers.
• Highly proficient in using standard test and measurement equipment—including oscilloscopes, function generators, and voltmeters—to benchmark, validate, and debug software performance.

Benefits

• Platinum‑level family health coverage (medical, dental, vision)
• Health and dependent care Flexible Spending Accounts (FSA)
• Employer 401(k) contributions
• 20 days of paid time off & 11 paid holidays
• Paid parental leave
• Fully stocked kitchen

Approximate base salary range: $142,113 – $186,063 per year. Total compensation includes base, bonus, equity, and benefits. Pay is based on post‑job‑application evaluation of candidate qualifications and experience.
