Close.io

At Close.io we’re building the sales communication platform of the future. We’ve built a next-generation CRM that eliminates manual data entry and helps sales teams close more deals. We are hiring product-focused engineers to help us unify the world's sales calls and emails into one beautiful workflow. Our backend tech stack currently includes Python (Flask, Gunicorn, TaskTiger), Elasticsearch, MongoDB, Postgres, and Redis running in Docker/Kubernetes on AWS. Our backend primarily serves a well-documented public API that our front-end JavaScript app consumes. We open source – using dozens of open source projects with contributions to many of them, and released some of our own.
