Software Engineer (Core Infrastructure)

About the Role

Core (aka Browserbase Core Infrastructure) is the backbone of everything we do. This team keeps our browsers running at scale, solving massive distributed systems challenges and making sure our platform is fast, reliable, and scalable.

What you’ll do

• Build, operate, and grow the Browserbase Core platform — designing and developing robust, scalable distributed backends with developer-friendly APIs.
• Work closely with the rest of Engineering, gathering input and providing great support so every team can build on Core with confidence.
• Help define, scope, and review key projects; set priorities on the roadmap; and sequence deliverables that push the platform forward.
• Establish and reinforce best practices around development, operations, and reliability.
• Continuously enhance the platform to meet rapidly expanding customer adoption and demand.
• Investigate, troubleshoot, and resolve operational issues that arise in production.

Technical skills

• Deep experience building and scaling distributed systems, with scale on the order of hundreds or thousands of instances.
• Strong expertise coding in Go or Typescript; bonus if you’ve touched Firecracker or similar VMMs.
• Familiarity with CI/CD pipelines, Kubernetes and Docker, message queues, relational databases, automated testing, performance optimization, and zero-downtime multi-region deployments.
• A systems-thinking mindset you understand how infrastructure choices ripple all the way up to customer experience.
• Have a strong sense of ownership and bias toward action.
• Are excited to work 5 days a week in our San Francisco HQ (or open to relocating here).

Why join us

• Work on some of the hardest problems in modern infrastructure.
• Build core technology that every Browserbase product depends on.
