Sr. or Staff Software Engineer – Backend/Python

Close is a bootstrapped, profitable, 100% remote, ~90 person team of thoughtful individuals who value autonomy and impact. We’re eager to make a product our customers fall in love with over and over again.

We 💛 small scaling businesses. Since 2013, we’ve been building a CRM  that focuses on better communication, without the hassle of manual data entry or complex UI. Our goal: double the productivity of every sales rep.

Our backend tech stack currently consists primarily of Python Flask web apps with our TaskTiger scheduler handling many of the backend asynchronous task processing chores. Our data stores include MongoDB, PostgreSQL, 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 Terraform, Ansible and other AWS tools.

We’re looking for high achieving full-time Software Engineers to join our engineering team. Someone who has a good understanding in web technologies and wants to help design, implement, launch, and scale major systems and user-facing features.

You’re comfortable working in a fast-paced environment with a small and talented team where you’re supported in your efforts to grow professionally. You’re able to manage your time well, communicate effectively and collaborate in a fully distributed team.
