Work type: remote
Location: USA - Remote
Salary: $140,000 – $210,000/yr
Type: Full-time
This role is ideal for a seasoned backend engineer with at least 5 years of experience (8+ for Staff level) who enjoys working in a high-scale, distributed environment. While Python is the primary language, the team values architectural expertise over specific syntax. You’ll thrive here if you have hands-on experience with high-volume data stores like MongoDB, PostgreSQL, or Elasticsearch and enjoy the "craftsmanship" side of building robust, public-facing APIs. The compensation is highly competitive ($140k–$210k) and comes with a standout "80% Work Option," allowing you to switch to a 4-day work week. As a 100-person, bootstrapped, and profitable company, they offer a stable alternative to the typical VC-backed burnout culture. Perks include a 6% 401k match, 5 weeks of PTO, and annual international retreats (Paris in 2025). **You might be a good fit if you:** * Want to solve complex scaling issues involving billions of documents and terabytes of logs. * Value autonomy and want to join a "no BS" team that prioritizes open-source contributions. * Are excited about integrating AI/LLMs to automate real-world sales workflows. * Prefer a 100% remote, USA-based role with a culture of discipline and transparency.
# About Us
[Close](https://close.com/) is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful individuals who prioritize taking ownership and making a meaningful 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 a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully designed, all-in-one, communication-focused CRM.
Our backend [tech stack](https://stackshare.io/close-crm/close) consists primarily of Python Flask web apps with our [TaskTiger](https://github.com/closeio/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. We have CI/CD pipelines that build Docker images, run automated tests and deploy to Kubernetes clusters. We also use these images in our local development environment allowing coding locally against all of our services. We have a well-documented [public API](https://developer.close.com/) that is consumed by our front-end JavaScript app as well as numerous integrations. Our infrastructure is heavily automated using Terraform, Ansible and other AWS tools.
We love open sourcing our code and ideas on [our GitHub](https://github.com/closeio) and on [The Making of Close](https://making.close.com/), our behind-the-scenes Product & Engineering blog. Check out our open source projects like [SocketShark](https://github.com/closeio/socketshark), [TaskTiger](https://github.com/closeio/tasktiger), [LimitLion](https://github.com/closeio/limitlion) and [ciso8601](https://github.com/closeio/ciso8601).
