Backend/Platform Software Engineer

We believe quantum computing will change everything.  It will have the power to transform the foundations of giant industries that rely on intensive computation.  PsiQuantum is on a mission to build the world’s first useful quantum computer, capable of delivering these transformative results.  We know that means it will need 1 million qubits, error correction, 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 is uniquely positioned to deliver on the promise of quantum computing years earlier than our competitors. Our architecture is based on photonics which gives us the ability to produce our components using existing high-volume semiconductor manufacturing processes, the same processes that are today producing billions of chips for telecom and consumer electronics applications. Since photons don’t feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like the Stanford Linear Accelerator (SLAC).  And because photons are in fact light, they can move between subsystems at tremendous speed using standard fiber connectivity.

Our team is building a utility scale quantum computer and the software tools needed to build fault tolerant quantum applications. We’re a highly motivated and collaborative group focused on a singular goal - building the world’s first useful quantum computer on the fastest path possible. 

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

Job Summary:

PsiQuantum is singularly focused on the delivery of a useful utility-scale fault tolerant quantum computer. In addition to deploying a world-class quantum computer, we aim to deliver a world-class quantum software user experience to both our external customers and internal developers.  After many years of development, we have created an incredible developer platform for the design of quantum algorithms.  We are now scaling our platform to many users while continuing to expand the power of our toolkit.

As our first in-house Senior Backend Platform Engineer, you’ll be instrumental in shaping our algorithm developer platform product.  You will take ownership of all our backend components and infrastructure, ensuring we have robust, secure, and scalable backend systems using AWS services. 

Responsibilities:

• Collaborate with development teams to ensure that infrastructure, automation, and monitoring are aligned with development and operational goals.
• Write robust, modular, and maintainable Infrastructure as Code (Terraform, AWS CDK, Pulumi) code to manage AWS infrastructure and operational tasks and integrations.
• Collaborate with the QA team to develop test plans and support testing to identify bugs and ensure systems function correctly before, during, and after deployment.
• Oversee GitLab environments, including version control, automated builds, and deployment processes.
• Develop and support our backend AWS architecture for scalability, reliability, and security, in collaboration with the IT, engineering, and product teams.
• Implement monitoring and logging tools to ensure system reliability and preemptively identify issues.  
• Implement security best practices in all stages of the development lifecycle, from design to deployment, including ensuring proper authentication and authorization controls.   Create and document best practices for ensuring system uptime and quickly resolving system failures.

Experience/Qualifications:

•  5+ years of experience in software engineering, with a strong focus on platform engineering, operations and DevOps practices.
• Proficiency in designing and managing infrastructure using EKS, ECS, Lambda, VPC, S3, etc.
• Knowledge and experience with CI/CD pipelines (Gitlab CI Pipeline/Github Actions), and cloud infrastructure-as-code tools like Terraform.
• Experience with containerized architecture (Docker, ECS) and microservices (Lambda, API Gateway) is a must.
• Experience with SQL and NoSQL database management (RDS, DynamoDB, Redis) is a must.
• Experience with security-related services (such as Okta, Auth0, IAM, and KMS) is a must.
• Familiarity with self-hosted or cloud-based Git systems.
• Experience with multi-environment infrastructure (dev, staging, prod) is a must.
• Familiarity providing hosted, managed IDEs to developers, data scientists, or researchers.
• Some experience building for public sector customers with compliance needs is a plus.
• Having AWS Certified Solutions Architect (SAA or SAP) or similar cloud certifications is a strong plus.
