👩🏽‍💻 Senior Full-stack Engineer

San Francisco, California
We're looking for several engineers who make phenomenal web applications, from front-end to back. That might be you if any or all of these apply:

🎨 You implement beautiful component systems with precision and accuracy.

🧬 You are comfortable designing complex data models, APIs, and back-end architectures.

⏱ You strive for easy deploys, peak performance, and continuous uptime.

🕵🏾‍♂️ And you build for easy diagnosability, just in case.

As a Full-stack Engineer, you'll work alongside our iOS, Android, and full-stack engineering team in handling scale, improving product insights, and crafting the OpenPhone experience.

We believe professional communication should be as easy as personal communication. Teams have Slack, groups have WhatsApp, but businesses are stuck with email and carrier calling. Our vision is to change all that, and we're starting with the phone. Today OpenPhone is the easiest way run a supercharged business phone from your personal device.


    • You've done this before. You've got a Bachelor's degree in Computer Science or a related field, or equivalent training or work experience.
    • You've built a deep understanding of web frameworks, reactive paradigms, and component lifecycles.
    • You have proven experience developing performant Javascript code and the ability to diagnose issues.
    • You've honed a detailed knowledge of AWS services, web development and debugging tools, and general deploy systems.
    • You've deployed and maintained apps using modern web technologies, especially Node.js, Redux, and PostgreSQL.
    • You love getting better at this. You want to always be improving your own work and your team's work.

Bonus Points

    • 🎨 If you lean toward the front-end, React or similar experience would be ideal.
    • ⏱ Our infrastructure is very new and lightweight — we're primarily using Serverless. If you love dev-ops, strong opinions on deploy and scaling infrastructure would be appreciated.
    • ☎️ If you've ever worked on a VoIP or SMS platform, or you're comfortable with the WebRTC or SIP, you might be a phenomenal fit.
    • 👩🏼‍🔧 As an early-stage company, our product, marketing, and billing data still live in different sources. We want to improve this, so if you have any experience architecting early data-flow systems, it would be a huge plus.
About Us

We're growing our customer base quickly and organically by focusing on deeply understanding our users and building the best product we can. It's working! So we recently closed our Seed round, found an office, and started devising our roadmap. If you're looking to make a huge impact at early stage with lots of promise, let's get to know one another.

We are also an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
