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OpenPhone is the modern, sophisticated answer to the clunky, outdated phone systems that have been slowing down businesses for years.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 Senior Backend Engineer at OpenPhone, you will spend a majority of your time coding, architecting, and owning moderate to complex components. Beyond your technical work, you may also lead a small team or a project. You might also spend time providing technical guidance, code reviews, and design and delivering on small/medium size projects end-to-end.
Potential areas of focus include:
- Leveraging AI and advanced technologies to help customers manage and derive insights from their data, optimizing the customer onboarding experience.
- Empowering users to independently set up, manage, and scale their accounts with a seamless and compliant process.
- Enhancing core messaging and calling features, improving customer data management, and optimizing the visibility of conversations and contacts.
In any of these areas, you’ll have the opportunity to tackle impactful challenges and help build scalable backend systems that will support a growing user base.
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
- Strong experience with Typescript, or experience with object-oriented languages such as Java or C# and Javascript/Node.
- Strong 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 support your teammates and customers through the continuous pursuit of knowledge. 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.
