Powering the world's messages

What we do

We provide a simple, developer-friendly interface to push notifications and email for apps and websites.

We started as app developers who just wanted a developer-friendly API for push notifications. Finding no good solution, we built one ourselves.

Today, we are the leading solution for push notifications and email, supporting over 691,440 developers. OneSignal is available on every platform and development environment that supports push, letting content creators focus on quality user engagement instead of complex implementation.

Our goal is to democratize communication tools for everyone from individual blogs to top tier apps.

What we believe

We strive to build a happy, healthy work environment driven by our core values:

We create an environment where each person directly helps the company meet its goals. We hire great people and bring out the best in each other through regular feedback, creating an inclusive and conscientious work environment, providing opportunities for learning, and being humble.

We provide mission-critical products for our clients and they depend on us for exceptional support, highly available service, great documentation, and listening to their feedback. Ensuring the success of our customers is everyone’s responsibility.

Huge leaps are made not by taking the road well traveled, but by trying novel approaches and occasionally succeeding. Because of the nature of risk taking, we celebrate both successes and failures, and we view such failures as a learning opportunity.

We lead by example, putting rigor into our work and communicating with transparency and intellectual honesty. To demonstrate this we set aggressive goals, address issues in their nascency, and take personal responsibility for helping the company meet its goals.

We believe that happiness, fun, and energy fuels creativity and innovation and creates a more open and communicative workplace. We host regular off-sites and social events to bring the team closer together. We’re grateful for our successes and we celebrate them.

We started as a Y Combinator-backed game developer. Our founders were frustrated with existing push notification tools, so we built our own system. It took off like wildfire. Now we help businesses send 4.5 Billion push notifications every single day. The company is growing quickly both in terms of revenue and employees.

  • Strong data analytics skills - including strong SQL skills and the ability to formulate / structure complex analyses to answer key product questions
  • Product execution - a demonstrated track record of delivering high-quality products at scale

Senior Backend Engineer

San Mateo, California


We're looking for an engineer interested in writing Rust. Experience with the language is not required, but we are looking for experience in some sort of statically typed language and a couple years of experience. We have several projects using Rust today including the OnePush delivery service, pstats, our stats daemon that runs on each server, and oscachemgr, a cache manager for our front end servers. We've recently started another Rust project pertaining to analytical work on our ever-growing data set. We're also starting to plan a project to integrate Rust into our Rails application. In addition to the Rust projects, business needs may at times require you to work on another part of the application such as Rails or infrastructure.


What you'll do:

  • Work closely with a small team shipping lots of code
  • Write Rust and Ruby
  • Add features to and improving our push delivery service
  • Work on native Rust extensions to our Rails application
  • Open source contributions - we have contributed patches to several crates and released one of our own. We aspire to do more of this as time progresses
  • Contribute to our stats monitoring process (Rust) which runs on all of our servers
  • Architect solutions to address our scaling needs
  • Design and build a custom message queue


Skills and experience:

  • 5+ years of experience writing software for distributed systems
  • Experience writing with a statically typed language such as Rust, Java, C++, etc
  • Solid understanding of web service architecture, systems and how they fit together such as: http clients, DNS, load balancers, reverse proxies, CDNs, application servers (ex. Rails), databases, and caches
  • Open to learning and writing Rust and Go
  • Proficiency in written and oral communications
  • Ability to collaborate well on a team
  • Friendliness and empathy
  • Modesty
  • Can deliver solutions independently
  • Love of learning


Preferred skills and experience:

  • Experience extending an interpreted language with native code
  • Familiarity with Redis, PostgreSQL and Kafka
  • Proficiency with Linux systems
  • Familiarity with POSIX C APIs
  • Understanding of how multiplexed I/O works
  • Again, these are nice-to-haves. Even if you don't know them, we hope you are interested in learning them!


Compensation:

  • Salary: $120k - $165k
  • Equity: 0.1% - 0.25%
