Senior Backend Software Engineer

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OpenPhone is the modern, sophisticated answer to the clunky, outdated phone systems that have been slowing down businesses for years.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 part of the Connect Squad within the Growth and Scale group, this Senior Backend Software Engineering role is pivotal in driving initiatives that directly contribute to our company's strategic objectives. Our team’s mandate is seamlessly connecting OpenPhone into the small business (SMB) tech stack to better support existing customers, capture new ones, and build strategic product partnerships.

Some of the areas you’ll support:

• OpenPhone’s (New) API: Architecting & building our very own public api. Our V1 Public API will allow users to programmatically send text messages, sync contacts, and log messages and calls to other applications in their tech stack. And this is the beginning!
• Integrations: Right now, we support integrations such as Hubspot and Salesforce. You’ll help us to move away from bespoke single integrations to supporting various integrations at scale. We’ll start by supporting CRM-type integrations and moving onto other integration types.
• Contacts: A key area of the product we plan to evolve this year. You’ll help us design and build an evolved solution with other teams and cross-functional stakeholders to scale efficiently.

Your contributions will directly impact our ability to grow and scale as a company. 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 lead a project. You might also spend time providing technical guidance, code reviews and design and deliver on small/medium size projects end-to-end.

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 how you found them.
