Team Overview 

PsiQuantum's Applications Software Engineering Team builds tools for quantum algorithm developers: cloud development environments, circuit design tools, and resource estimation systems that help researchers write, simulate, and optimize quantum algorithms for the world's first utility-scale, fault-tolerant quantum computer. 

We're hiring a platform engineer who bridges software infrastructure with GPU-accelerated computing, someone who can improve our AWS platform while helping researchers run quantum simulations efficiently on GPU clusters.  

Role Overview 

We're looking for someone to partner with our existing platform engineer, splitting responsibilities across a growing platform and making it easier for quantum researchers to do their best work. 

That platform includes AWS infrastructure, Terraform configs, CI/CD workflows, and the GPU clusters our researchers depend on for large-scale, computationally intensive quantum simulations. There's a real opportunity to shape how all of it evolves. 

The right person for this role is comfortable making judgment calls under uncertainty; they will have a lot of latitude, and accountability to match. 

Responsibilities:

How You’ll Spend Your Time 

Platform Engineering (70%)  

• Own our AWS infrastructure end-to-end and actively shape how it evolves; building, not just maintaining.
• Reduce friction in the deployment pipeline so developers can ship without infrastructure blockers.
• Harden systems with intention: lock down IAM roles, container images, and authentication flows in ways that reflect a clear understanding of where the real risks are.
• Implement monitoring and alerting that catches production issues before users notice them.
• Make deployments faster to roll out, easier to roll back, and less prone to failure.
• Lead incident response and post-mortems when necessary.

GPU/HPC Bridge Work (30%) 

• Make GPU clusters and other infrastructure invisible to the researchers running it.
• Own CUDA compatibility and driver versions across heterogeneous GPU clusters.
• Build standardized SLURM job submission workflows that researchers can use without help.
• Package and containerize Python simulation code for reproducible execution.
• Monitor job health across utilization, cost, and runtime efficiency.

Experience/Qualifications:

Required Qualifications 

• Experience: 5+ years in Platform Engineering, DevOps, or SRE roles.
• Production AWS experience: Built and maintained systems on ECS/EKS, managed multi-account networking (VPCs, security groups), and dealt with real-world infrastructure complexity.
• Infrastructure as Code: You've written and maintained Terraform (or Pulumi/CDK) in production, including applying ongoing changes as requirements evolved.
• CI/CD: Improved build pipelines in production (reduced build times, increased reliability, made deployments easier to debug), including experience with GitLab CI, GitHub Actions, or equivalent.
• GPU/HPC experience: Supported GPU workloads in production environments, including code optimization, CUDA debugging, and job scheduler setup.

Preferred Qualifications 

• Background in scientific computing, research infrastructure, ML platforms, or early-stage startups (especially research computing vendors).
• Security & compliance experience: You've implemented auth systems (Auth0/Okta), managed encryption (KMS), or worked on FedRAMP/compliance-driven infrastructure. FedRAMP experience is a strong plus.
• Exposure to quantum computing SDKs (Qiskit, Cirq, PennyLane) or hybrid classical-quantum workflows is a plus, but not required; genuine interest in quantum computing matters more than prior exposure.

What We’re Not Looking For 

• Candidates focused on enterprise-scale batch computing rather than cloud-native platform engineering.
• Platform engineers without exposure to GPU workloads or HPC concepts.
• Candidates who prioritize architectural purity over iterative delivery.

PsiQuantum provides equal employment opportunity for all applicants and employees. PsiQuantum does not unlawfully discriminate on the basis of race, color, religion, sex (including pregnancy, childbirth, or related medical conditions), gender identity, gender expression, national origin, ancestry, citizenship, age, physical or mental disability, military or veteran status, marital status, domestic partner status, sexual orientation, genetic information, or any other basis protected by applicable laws.

PsiQuantum’s mission is to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. 

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries. 

Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. 

In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale. 

PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact. 

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Job Summary:

Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum we’re building a general-purpose silicon photonic quantum computer to tackle these very problems.

We are seeking a senior API & Workflow Platform Architect to design and scale the integration architecture that connects our photonic IC (PIC), passive, and active IC design toolchains. Our engineering workflows span schematic capture, layout, DRC/LVS, EM simulation, optical modeling, process modeling, packaging co-design, and silicon validation. These flows rely on a combination of commercial EDA tools, in-house solvers, Python-based automation, and data pipelines.

An ideal candidate is a systems-minded API and workflow architect who thrives at the intersection of SW engineering and advanced hardware design environments (photonics, semiconductor, or EDA toolchains). They bring deep experience designing and governing APIs across heterogeneous systems—proprietary CAD tools, simulation engines, layout databases, EM/optical solvers, test platforms, and CI/CD pipelines—while defining canonical data models that preserve design intent and traceability from schematic through layout, extraction, verification, and tape-out. They are equally comfortable writing production-grade Python services and debating schema versioning strategy, event-driven orchestration, or data lineage requirements. The ideal candidate combines architectural rigor with pragmatism: able to reduce toolchain chaos into scalable, observable, and secure integration platforms that enable automation, reproducibility, and rapid innovation across PIC, passive, and active IC design teams. Above all, they think in systems, communicate clearly across software and device engineering teams, and build platforms that others are excited to adopt.

Responsibilities:

• Key member of the software solutions team responsible for developing and deploying software for test systems, product platforms and manufacturing data management.
• Design and standardize APIs enabling interoperability between EDA tools, in-house photonic solvers, PDK infrastructure, and CI/CD systems (Gitlab is a plus).
• Build and maintain middleware/adapters for commercial and proprietary tools with inconsistent or limited APIs.
• Establish API versioning, schema validation, and backward compatibility strategies to support evolving toolchains without breaking downstream flows.
• Implement observability and traceability mechanisms (logging, metrics, lineage tracking) to ensure reproducibility and auditability of design runs.
• Collaborate with device, layout, and simulation engineers to translate domain requirements into robust platform abstractions.

Experience/Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Physics, or related technical field.
• 7+ years of software engineering experience, with significant exposure to systems integration or platform architecture.
• Proven experience designing and governing APIs (REST, gRPC, event-driven architectures) in complex, multi-tool environments.
• Familiarity with data interchange formats (protocol buffers, avro, etc.)
• Experience integrating with data platforms (DataBricks, Tableau, etc.)
• Strong programming skills in Python (required) and at least one systems or backend language (Go, C++, Java, Rust, or similar).
• Experience integrating heterogeneous tools, including proprietary or vendor software with limited or inconsistent APIs.
• Demonstrated experience defining canonical data models and managing schema/versioning strategy.
• Familiarity with CI/CD systems, containerization (Docker), and orchestration platforms (e.g., Kubernetes or equivalent).
• Experience implementing logging, monitoring, and observability for distributed systems.
• Strong understanding of software architecture principles: modularity, loose coupling, scalability, reliability.
• Experience working in engineering-heavy domains (EDA, semiconductor, hardware, scientific computing, or similar).
• Proven team player with an ability to work effectively across departments, sites, time zones.
• Excellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences.
• Strong critical thinking, creative, innovative, analytical, and detail-oriented problem-solving skills.
• Proven track record of impactful results.
• Ability to work independently with limited direction.
• Demonstrated ability to lead and juggle multiple priorities and deliver against a schedule.
• Demonstrated interest in quantum computing.
• Ability to contribute to a fast-paced start-up environment.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries. 

Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. 

In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale. 

PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact. 

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

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!

PsiQuantum’s mission is to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. 

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries. 

Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. 

In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale. 

PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact. 

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.
