AppFolio is more than a company. We’re a community of dreamers, big thinkers, problem solvers, active listeners, and multipliers. At every opportunity, we set the pace while delivering innovation built to carry real estate into the future. One in which every experience feels effortless, yet meaningful. Where customers are empowered to take on any opportunity. We show up as one team, connected by our values to be a force for good. Because together, we have the power to create extraordinary outcomes for our customers, our communities, and ourselves.
What You’ll Do
You will be helping them to build common infrastructure as well as help improve the reliability, quality of services and overall observability patterns.  Along with your team, you’ll ensure all aspects of our shared product spaces have a plan to address any opportunities for exception reporting, capacity planning, monitoring and alerting, backups, runbooks, configuration management, DDoS protection, infrastructure as code, and disaster recovery. You’ll collaborate or embed with engineering teams, helping them to improve the reliability and quality of their services and infrastructure as we look to support the business success of AppFolio.
You’ll be a member of the team that provides reliable, scalable observability and infrastructure for key components of the AppFolio Real Estate Platform. You’ll help build the future of reliable, critical services, and support rapid and sustainable growth of new features.

Must-Haves
  • Experience developing Service Level Indicators and Service Level Objectives for the above systems.
  • Proven ability to diagnose and monitor performance and reliability issues across the stack: relational databases, web servers, networking, OS, containers, load balancers, etc. You’ll chase down performance problems and uncover root causes of system failures.
  • Strong coding background: you’ve written code to perform critical tasks or in production. The exact language doesn’t matter, though we give bonus points for Go, Ruby, or Python.
  • Expertise with Infrastructure as Code (Terraform, CloudFormation, Pulumi, etc.)
  • Expertise with Kubernetes or other container orchestration tooling and technology patterns
  • Experience with Amazon Web Services (commonly EKS, RDS Aurora, Lambda, S3, EBS, Route53, DynamoDB, and VPCs)
  • Bachelor’s degree and at least 5 years industry experience, or equivalent work experience
Ways To Stand Out From The Crowd
  • Mastery experience with some areas of our tech like Ruby on Rails, Kubernetes, MySQL, Linux, container orchestration, Networking, etc.
