Job description

About the Company

Logiqal is on a mission to build the first scaled quantum computer, deploying millions of qubits to tackle the world’s most important problems. Our thesis is that you have to build a full scale machine to learn what the actual hard parts are, just like you have to build a full scale rocket before the first launch. We’re looking for a few visionary scientists and engineers to join our team, to move fast and blow stuff up.

Based in Princeton, NJ our founding physics team has decades of combined research experience at leading academic and industry labs including Princeton, Harvard, Yale, MIT and Google Quantum. Our approach is based on neutral atom qubit technology developed in research labs at Princeton by the founding team. Our scalable systems are composed of manufacturable sub-modules, controlled by state-of-the-art CMOS optoelectronics, and designed around a unique computer architecture.

If you’re excited to build something that’s never existed before at the cutting edge of physics and engineering—together with an awesome team with deep technical expertise—come build with us!

About the Role

As a Software Engineer on the controls side, you will develop and own components that enable nanosecond-level timing of laser modulation signals, precision acquisition from high-speed cameras, and complex system-of-systems monitoring and diagnostics. We are looking for candidates who can work across the software/hardware boundary with strong backgrounds in hardware-in-the-loop testing, data pipelines for calibration and operations, and distributed infrastructure monitoring and control. You will collaborate with atomic physicists and other controls engineers to establish and monitor performance benchmarks that ensure our controls stack sustains robust, distributed quantum computations.

This position requires hands‑on instrumentation work and strong software fundamentals. It benefits from experience integrating technologies such as high‑speed cameras, RF signal generators, GPUs, and Linux kernel customizations. A physics background is a plus but not essential — we find that engineers from adjacent fields bring valuable perspective. No knowledge of quantum computing is not required, though we’re happy to teach you.

__________

Compensation consists of a base salary and equity. The salary range for this role is $150-235k, commensurate with experience. We also provide comprehensive benefits, including fully paid medical, dental, and vision insurance for our employees and highly subsidized benefits for spouses and dependents, a 401k and FSA.
