Company mission
To build and deploy useful, fault tolerant quantum computers.
Role
Who you are
- 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
What the job involves
- 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
- 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
Our take
Quantum computing will change the world more than any other imminent technological development, and PsiQuantum sits at the forefront of the charge to build the first quantum computer that will actually work.
The company is unique for the scale of their ambitions. Rather than focusing on what they term “intermediate milestones” like building smaller proof of concept systems, PsiQuantum builds the first large-scale, error-corrected computer, using photonics to deliver over 1,000,000 qubits (current quantum machines have yet to cross the 1,000 qubit mark).
There are plenty of companies building quantum computers, including the likes of IBM and Google, but these prototypical machines lack the size to correct errors, making them exponentially less useful than what PsiQuantum aims for. While other companies operate in the same sphere, PsiQuantum is unequivocally a leader in its field, founded by world-class academics and recently securing $1B in funding, making it the largest funding round for a quantum computing startup.
