Software Engineer, Infrastructure

Cursor; California (MO); On-site; USD 120,000 - 180,000; Full time

Job summary

Cursor is building the best tool for professional programmers, owning the cloud and networking foundations that power production. You will shape the infrastructure, cost strategy, and multi-region deployment while enabling teams to ship faster.

As an Infrastructure-focused Software Engineer, you will operate Kubernetes clusters at scale, manage edge security, and drive reproducible, self-serve infrastructure across the organization.

Qualifications

• Deep experience with AWS and VPC networking.
• Operated production Kubernetes clusters at scale with service mesh and autoscaling.
• Understanding of edge networking, CDN/WAF architectures, and traffic management.
• Infrastructure-as-code and reproducibility for self-serve infrastructure.
• Cost optimization at scale or infrastructure migration/unification is a plus.

Responsibilities

• Own the foundational cloud and networking layer that services run on.
• Drive cost management, regional deployment strategy, and infrastructure unification.
• Design and maintain the compute platform and container orchestration strategy.
• Build edge and security infrastructure to protect against abuse and optimize traffic routing.
• Unify deployment patterns across teams to ensure reliable, scalable production.

Job description

Our mission is to automate coding. The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.

About the Role

As a Software Engineer on the Infrastructure team at Cursor, you'll own the foundational cloud and networking layer that every service runs on: network foundations, container orchestration, edge and security infrastructure, and the compute runtimes that power production.

Cursor is one of the fastest-growing developer tools in the world, and you'll drive the cost management, regional deployment strategy, and infrastructure unification that make that growth possible. When your systems work well, every team is more productive, every product surface is more reliable, and Cursor can expand to serve developers everywhere.

Example projects include...

• Owning Kubernetes and cluster foundations: building and operating production clusters with proper service mesh, scaling, and ingress that teams can confidently deploy to.
• Designing the geo-deployment architecture: building a replicable, robust process for deploying geo-replicated services across cloud regions and providers.
• Building edge and security infrastructure: designing the networking and security layer at the edge to protect against abuse, manage rate limiting, and optimize traffic routing.
• Owning cost management and optimization: building attribution systems, identifying waste, and ensuring we're making smart tradeoffs between cost and reliability across all cloud spend.
• Unifying the compute platform: defining a single, opinionated container orchestration strategy so every team gets consistent, reliable deployments out of the box.

You may be a fit if

• You have deep experience with AWS (or comparable cloud providers), especially VPC networking, EKS/K8s, and IAM/account management.
• You've built and operated production Kubernetes clusters at scale, including service mesh, autoscaling, and multi-region deployments.
• You understand edge networking, CDN/WAF architectures, and traffic management at the infrastructure level.
• You care about infrastructure-as-code, reproducibility, and making it easy for other teams to self-serve reliable infrastructure.
• Experience with cost optimization at scale or infrastructure migration/unification is a plus.
• You have strong software engineering fundamentals and enjoy building the platform that makes every other team faster.
