Since 2013, we’ve been building a CRM that gets out of your way and helps your team sell more, faster. Now we’re building AI into every part of it, so Close does the busywork and your team does the selling. No manual data entry, no 10-click workflows. Just communication-first, AI-powered sales software designed to help you succeed and scale.
We're bootstrapped and profitable which means we answer to our customers and play by our rules. We're proud of our 120-person, 100% remote team, focused on building Close so that no small, scaling business fails because it can't figure out sales.
Our backend tech stack 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 ElastiCache 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 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 and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check out our open source projects like SocketShark, TaskTiger, LimitLion and ciso8601.
AI is both how we build and what we ship, and that's reshaped what engineering looks like. This is a transformation we’re embracing and find deeply exciting.
Close runs on Python: Flask web apps, TaskTiger, billions of MongoDB documents, a public REST API that customers and external agents both build on. Four product teams ship features on top of that every week. Backend Platform owns the layer underneath them.
The work is building for other engineers. When a product team adds a new API endpoint, most of what they write isn't their feature — it's wiring: authentication, permissions, rate limiting, the shape the endpoint has to take so it looks like every other endpoint when you squint. Multiply that across telemetry, eventing, database migrations, authorization, and local development, and you get the problem this team exists to solve: make the paved road faster to walk than the trail.
The other half of the team's mandate is the AI development platform. We've built DevDawg, cloud-based development environments preconfigured for our entire application stack and our engineering practices, and Spice, our extension layer on top of a coding agent that runs internal review workflows and root cause analysis. Spice is hooked into GitHub and can already approve mergeable pull requests on its own for simple changes. Expanding what it can safely handle is squarely this team's work.
This is a new team. You would be one of the first hires, and you'd have unusual influence over what the team owns and how it works.
One thing to know up front: we do move people between teams as the work shifts. Most engineers here end up on more than one team over their time at Close — this team is where you'd start, but over time you'll likely have the opportunity to work on many different projects.
This role is open at the Senior and Staff levels. You don't need to pick one when you apply: we'll calibrate together during the process.
Tech you'll touch: Python, Flask, FastAPI, GraphQL, TaskTiger, Rust, Typescript, Kafka, Redis, MongoDB, PostgreSQL, Elasticsearch, Docker, Kubernetes, GitHub Actions — plus whatever coding agent ships next.

We ask a few role-specific questions as part of our application process. These questions are designed to help us learn more about you from the start, so please answer each one thoughtfully. We see this as an opportunity to get to know you beyond your resume.
We use AI tools daily at Close and expect candidates to do the same. In evaluating your application, we aim to get a sense for you - the way you think, how you communicate, the work you've done. Applications that read as fully AI-generated will not be considered.
Regardless of fit, you can expect to hear back from our team with an update on the status of your candidacy.
If you progress to the interview process, you'll receive a full outline of the role-specific steps in your first touchpoint with us. We do our best to make the hiring process clear and human.

Close is Fully Remote and has been since 2016, with a team spread across more than 20 countries. Some roles are open only to candidates in the United States, and all current openings are US-only, 100% remote positions.
The careers page lays out a set sequence: an application review, a video intro call, a skills assessment (a 3 to 6 hour take-home that Close says is never used as real work product), video interviews, a final video interview with the founder or VP of Engineering, and reference checks.
Highlights from the careers page include 5 weeks of PTO that grows by 2 days for each year of tenure plus a company-wide winter break, a fully paid 4-week sabbatical every 5 years, a 401(k) with a 6% match that is immediately vested, and medical, dental, and vision coverage where Close pays 99% of monthly premiums.
Close's careers page mentions possible four-day workweeks as part of its async, autonomous culture. Job descriptions specify that this option runs at 80% pay and requires manager approval.
Close suits people building products for inside sales teams at small, scaling businesses, and who thrive with autonomy rather than oversight. Because the company does not track hours and prioritizes written, asynchronous work, it fits self-directed people who prefer flexible hours over a fixed office schedule.
