Full-time
For millions of teams working in dozens of industries, day-to-day business gets done on the phone. So why — despite the huge leaps we've taken in design and usability — does most business phone software still look, feel, and act like it was born in the 90s? OpenPhone is changing that.
We’re a new type of business phone with a mission to help people communicate better and be more productive.
We’re backed by Y Combinator and some of the best venture firms around including Tiger Global, Craft Ventures, Slow Ventures, and others. We take pride in providing an exceptional customer experience and a product people love, which is why we’re excited that our customers have rated us the #1 VoIP Provider on G2.
OpenPhone is the modern, sophisticated answer to the clunky, outdated phone systems that have been slowing down businesses for years. With thousands of happy customers and several rounds of funding in just five years, it's safe to say we're onto something big.
About the Role
As a Backend Engineer at OpenPhone, you'll join a dynamic team working on our innovative communication platform for small and medium-sized businesses. You'll contribute to one of our specialized engineering pillars that power different aspects of our growing platform, and join one of our teams across our Engineering pillars, who own different areas of our platform:
- Workflow Automation, who develop a highly configurable workflow engine that caters to the diverse operational needs of SMBs using OpenPhone.
- Communication, who improve messaging, calling, and internal collaboration features for customer-facing teams and their managers.
- Connect, who connect OpenPhone into the SMB tech stack to better support existing customers, capture new ones, and build strategic product partnerships.
- AI Agent Engine, who own and build our AI Agent, Sona
Technical stack and tools:
- Our backend is built on Node using Typescript.
- We use Kubernetes on AWS to orchestrate our infrastructure setup and deployment.
- The overall architecture is event-driven microservices with RabbitMQ at the center of it.
- We use a variety of databases for different purposes: Postgres, Mongo, Elastic, and Redis.
- We use Kong as our public API Gateway.
- Observability Tools: Datadog
- Other Tools: Figma, Linear, Notion, and Slack
About you:
- Experience with Typescript, or experience with object-oriented languages such as Java or C# and Javascript/Node.
- Experience with observability tools, including metrics, structured logging and distributed tracing
- You take ownership of your work and understand the importance of communication. You hold yourself to a high standard and help empower others to do the same.
- You are intentional about how your work impacts customers, the community, and each other. You practice empathy, generosity, and thoughtfulness as you evaluate tradeoffs in pursuit of the best solution.
- You are curious. You better seek to understand the ‘why’ behind things, so that you can better plan and build the ‘how’. You don’t hesitate to ask the questions when necessary. You’re a lifelong learner.
- Your code is a pleasure for your teammates to read and understand and you strive to ensure it is readable, testable, and maintainable. When working in the codebase, you leave things better than you found them.
