Software Systems Architect

About us

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 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.

We’re assembling a founding team to help us build the full‑stack systems that will power this next leap in computing.

If you’re excited to build something that’s never existed before at the cutting edge of physics and engineering, the chance to shape both the technology and the company from the ground up, come build with us!

About this role

This is a senior systems‑level engineering and architecture role focused on controlling hardware, acquiring and analyzing large volumes of data, and eventually enabling microsecond‑scale decision‑making. You will design and lead implementation for our core software stack.

You’ll work directly with physicists and hardware engineers to design our core software stack, and refine your designs using real workloads as our machines come online. You’ll build:

• Hardware Control Interfaces: Software layers that communicate with cameras, data acquisition systems, and other electronic devices. You’ll design clean abstractions so we can swap hardware components without rewriting the whole stack.

• High‑Throughput Data Acquisition & Storage: Systems to ingest and archive multiple terabytes per day of diagnostic and camera data, with pipelines for both real‑time and offline analysis.

• Low‑Latency Distributed Systems: Infrastructure capable of dispatching commands to hardware with low‑latency (sub‑100 μsec) performance across a distributed system.

You might be a good fit if you have experience with:

• Leading projects and mentoring junior engineers

• C/C++ or Rust for systems programming

• Systems‑level architecture for controlling large arrays of hardware devices (e.g., robotics, lab instrumentation).

• Designing stable APIs for hardware systems

• Communication and device I/O: Ethernet/UDP/TCP, PCIe, DMA

• Real‑time Linux environments and deterministic scheduling

• High‑rate data acquisition (TBs/day scale)

No quantum physics knowledge required (although we’re happy to teach you).

Logiqal provides a comprehensive range of perks and benefits, including:

• fully paid medical, dental, and vision insurance for employees (with a significant contribution for dependent coverage)

• unlimited paid time off for vacation, sick leave and personal days

• equity in the company.

The base salary range for this position is between $150,000 - $215,000, commensurate with experience.
