Quantum computing holds the promise of humanity's mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.

By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today's most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.

PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don't feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.

In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing's potential impact and the need to scale this technology to unlock that potential. And we won't just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.

Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.

There's much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

Join our OS/Platform team to build and operate a unified, high-performance observability and data-acquisition platform that supports both our on-premises datacenters and growing AWS footprint. You will design and automate infrastructure with Terraform and Kubernetes, develop Python tooling to streamline workflows, and integrate metrics, logs, and traces so product teams can monitor services in real time, troubleshoot confidently, and ship software quickly and safely.

Responsibilities:

• Architect document and implement a data acquisition and observability framework, supporting logs, metrics, and traces.
• Develop high-throughput data pipelines for ingestion, transformation, and storage.
• Build API services and integrations for system monitoring and device communication.
• Optimize pipeline performance for low-latency, high-bandwidth environments.
• Collaborate with calibration and infrastructure engineers on deployment and data engineers on schema and reporting needs.
• Maintain monitoring, alerting, and visualization tools for system observability.
• Ensure security, compliance, and scalability across cloud and on-prem environments.
• Gather functional requirements from external stakeholders, refining them into technical requirements considering performance, scalability, and usability.
• Troubleshoot complex problems and incidents, working with cross-functional teams and end-users to identify root causes.

Experience/Qualifications:

• Bachelor's Degree or higher in Computer Science, Engineering or other related technical field.
• 10+ years designing and operating infrastructure using Terraform (or similar) and Kubernetes.
• Python development skills focused on automation and tooling.
• Practical experience configuring and managing GitLab CI/CD.
• Proven success deploying observability stacks (Grafana, Prometheus, Loki, Tempo) in production.
• Working knowledge of core AWS services and networking fundamentals.
• Experience with Kafka a plus.
• Familiarity with regulated industry requirements and cross-regional architectures.
• Excellent communication, problem-solving, and cross-team collaboration skills; comfortable acting as a platform generalist.
