Site Reliability Engineer

The AdGear Site Reliability Engineer is a software engineer responsible for ensuring that the AdGear platform's services are designed, implemented, deployed, and operated such that they are highly available, highly performing, and scalable.

The ideal candidate for the Site Reliability Engineer position typically self-identifies as a "hacker", who is both a "jack of all trades" as well as possesses deep knowledge in multiple areas of software development, Linux/unix systems administration, networking, internet protocols, databases, and distributed systems. The ideal candidate has a mix of software development and infrastructure operations skills, and approaches infrastructure operations from the perspective of a software engineer.

You'll be working in a small team of SREs, supporting a medium-sized team of software engineers working on building the next generation of AdGear's administrative interfaces, ad decisioning, delivery, data processing and analytics systems.

Relevant industry experience is important, but ultimately less so than your demonstrated abilities and attitude.

  • Continual improvement of internal services for ease of packaging, configuration and deployment
  • Monitoring of all critical services, sharing pager duty, troubleshooting and addressing problems as they arise (including any needed changes in code, topology, resources, or configuration)
  • Backups/DR implementation, plans, documentation and exercises
  • Co-own technical relationships with several service providers and vendors

  • You enjoy working with others who are smart and passionate about building useful, reliable, performant products
