❄️ Please note: Our team will be on Winter Break from December 23rd - January 3rd. We will not be reviewing applications during this time. We will do our best to share an update on your candidacy promptly in the new year.
We are looking for US-based Software Engineers to join our team. Base salary range for Senior I II is $140,000 to $210,000.
About Us
Close 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 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. 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.
Our product development process is inspired by Shape Up. 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.

How We Work Together
- Productivity, Quality Impact: We don’t track hours. We trust you’re an adult and know best how to prioritize, meet your goals and contribute at a high level.
- Asynchronous communication collaboration: We have team members all over the world. We don’t expect anyone to work untraditional hours, that means our default is async. Most teams have 2-5 hours of internal meetings weekly.
- Appreciation for Deep Work: *During your normal work day, not after a day of meetings*.
- Autonomy Freedom: Create a work environment that is sustainable for you. We place a high amount of trust and responsibility with our team members from the start.
Working from 22+ countries, we’re a collection of talented humans rich in diverse backgrounds, lifestyles, and cultures. Close has been 100% remote since 2016, creating an intentional workplace around asynchronous communication and collaboration. Every year we meet up somewhere around the world to spend time with one another. These gatherings are an opportunity to strengthen the relationships within our global community.
We practice a mature approach to the workplace -- manage your time effectively, communicate thoughtfully with your teammates and customers, and produce high quality work. We have impressive tenure amongst the team; we stay at Close because we love working with our colleagues, we appreciate the autonomy, and we thrive in an environment that challenges us to do our best work.
Unanimously, our favorite value is “Build a house you want to live in.” We make decisions that are rooted in helping our customers become more successful. We care equally about the health of our business and the wellbeing of our people.
Our application process was designed to promote equitable and unbiased hiring practices. We ask a small series of questions that are similar to what would be asked in the first interview. This helps us learn more about you right from the start so please be sure to answer each question thoughtfully. Regardless of fit, you will hear back from us letting you know if we'll be moving forward.
While we are excited by all the opportunities that generative AI has unlocked, we request that you refrain from relying on AI tools when completing an application. We ask these questions because we want to get to know you, your experience, and your communication style. All responses are read closely by multiple humans and any obviously AI generated applications will be disregarded.
