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 881,669 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.

When you pick up your smartphone, the first thing you’ll see are push notifications - maybe there’s a breaking news alert, an HQ Trivia game reminder, a promo from Princeton Review… Whatever it is, chances are the message you’re reading was sent using OneSignal. 750,000 mobile app developers and marketing teams use OneSignal to send push notifications. 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 over 5 Billion push notifications every single day. We are looking for an Executive Assistant who thrives in a fast-paced and entrepreneurial environment. In this role, you will support the calendar and day-to-day operations of our Leadership Team. You will take on a variety of administrative and project coordination tasks.


What you'll do:

  • Interacting with c-level executives and board members
  • Receiving candidates and visitors to the office
  • Providing support on presentations and department-wide programming such as all hands meetings and planning sessions
  • Identifying operational weaknesses and help to refine processes or develop new ones
  • Handling complex calendars on an ongoing basis and prioritizing commitments to maximize time and productivity
  • Arranging complex and detailed travel plans, itineraries, and agendas
  • Supporting our recruiting Initiatives through coordinating, booking travel and scheduling candidate calls and onsite interviews
  • Handling confidential information with discretion


Skills and experience:

  • Have 3+ years of administrative assistant, executive assistant, or similar experience managing and supporting multiple senior leaders 
  • Have experience working in a fast-paced startup wearing multiple hats and pitching in where needed
  • Possess strong verbal and written communication skills
  • Have a can-do "make it happen" attitude: you are comfortable making decisions with little supervision or direction
  • Experience working with Slack, Zoom, Google tools and/or Mac/iOS are bonus  


In keeping with our beliefs and goals, no employee or applicant will face discrimination/harassment based on: race, color, ancestry, national origin, religion, age, gender, marital domestic partner status, sexual orientation, gender identity, disability status, or veteran status. Above and beyond discrimination/harassment based on 'protected categories,' we also strive to prevent other, subtler forms of inappropriate behavior (e.g., stereotyping) from ever gaining a foothold in our office. Whether blatant or hidden, barriers to success have no place at OneSignal.

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

  • 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!
