Job Description
Y Combinator is seeking an Infrastructure Software Engineer who will help manage and evolve the shared infrastructure that our software runs on. We have a team of approximately 15 Product Engineers who develop YC’s software products. Those products are developed in Ruby on Rails and run in AWS. Our team’s job is to provide a platform so our Product Engineers don’t have to think (as much) about infrastructure.
The ideal candidate will have experience debugging and developing a very broad stack. They’re comfortable talking about HTTP caching, AWS security groups, Rails monkey patching, n+1 queries in Active Record, CSRF protection, and React components.
Enjoy the many perks of working for a successful company – competitive salary and excellent benefits including fully-paid health care benefits and unlimited vacation – while working on a small, fast-moving and high-impact team.
In your first month, you might:
- Migrate a Rails application from Capistrano and EC2 to Docker and ECS
- Upgrade one of our applications to a newer version of Postgres or Rails
- Move more of our AWS infrastructure into Terraform
- Simplify our use of Webpack and Javascript for both developer productivity and faster deployments
- Create shared infrastructure to help manage email subscriptions and unsubscribes across 5 different product teams
- Triage and respond to bug bounty reports
- Work with outside security auditors to run a penetration test against our applications
Key Responsibilities:
- Provide a stable modern platform for our applications to be deployed to
- Keep our applications and data secure
- Improve our developer experience and tools so the YC Software Team can ship product updates quickly
- Help debug performance issues in our web applications
- Ship Ruby on Rails and TypeScript code that is shared among multiple YC applications
Skills:
- You know how to develop and debug MVC web applications. We use Ruby on Rails, Postgres, and React, but don’t worry if you haven’t used those specific technologies before
- You know how to deploy and run applications with AWS and Docker
- You use Terraform to make infrastructure changes
Experience:
- You have at least 5 years of experience developing and deploying web applications
- You are deeply familiar with the AWS platform specifically ECS, RDS, IAM, and CloudWatch
