Site Reliability Engineer

Remote, anywhere

At Close, we're building the sales communication platform of the future. With our roots as the very first sales CRM to include built-in calling, we're leading the industry toward eliminating manual processes and helping companies to close more deals(faster). Since our founding in 2013, we've grown to become a profitable, 100% globally distributed team of 60+ high-performing, happy people that are dedicated to building a product our customers love.

Our backend tech stack currently consists of Python Flask web apps with our TaskTiger scheduler handling many of the backend asynchronous task processing chores. Our data stores include MongoDB, Postgres, Elasticsearch, and Redis. The underlying infrastructure runs on AWS using a combination of managed services like EKS, MSK, RDS and ElasticCache and non-managed services running on EC2 instances. All of our compute runs through CI/CD pipelines that build Docker images, run automated tests and deploy to our Kubernetes clusters. Our backend primarily serves a well-documented public API that our front-end JavaScript app consumes. Our infrastructure is heavily automated using AWS tools, Terraform, and Ansible.

We open source – using dozens of open source projects with contributions to many of them, and released some of our own like ciso8601, LimitLion, SocketShark, TaskTiger, and more at
