About OneSignal

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

Today, OneSignal is the leading solution for sending effective messages across channels including mobile push notifications, web push notifications, in-app messaging, SMS, and email. We support over 1,400,000 of the world's leading marketers and developers.

OneSignal is available on every platform and development environment, letting content creators focus on quality user engagement instead of complex implementation.

Covid-19's Impact on OneSignal

Covid-19 has accelerated OneSignal's growth. Near the beginning of Covid, we saw a 20%+ increase in new accounts created for OneSignal each day and a 20%+ increase in daily message delivery volume. This trend has continued as more businesses seek to better engage with their customers on digital channels.

We are growing faster than ever, and hiring in all departments. We hope you'll apply and we look forward to meeting you!

About the role

Skills: RabbitMQ, TypeScript, Ruby on Rails

OneSignal has a lot of the great tech startup qualities you'd expect, but we don't stop there. Our massive scale and small team, emphasis on healthy life balance and kindness in all our interactions, and focus on ownership and personal growth make OneSignal a uniquely great place to work.

Our product engineering group builds our main product interface (https://www.onesignal.com) and API. With over 9 billion messages sent each day and over 1 million users, our small team’s work makes a massive impact. We tackle challenges at the intersection of engineering and product development, like notification authoring for over a dozen different platforms and multiple mediums (push, in-app, SMS, and email) and intelligent message delivery customized to each recipient.

Our team engineering process is extremely lightweight (inspired by the original Agile Manifesto), driven by clear ownership, and built for learning. We work closely with our product and design teams throughout the development process and opt for collaboration over hand-offs. As part of our team, you’d help build the technical foundations for great new features and drive those features from inception through completion.

Since we’ve built our early MVPs and found product-market fit, we’re now building the systems we need to scale our product and productivity for the future. That means a core part of our short term work is remodeling our early systems for the long term by paying down technical debt and putting maintainability before magic. If this sounds like a good challenge, you'll find constant support from your peers up through executive management. All our managers are highly technical and know that great engineering is the key to our continued success.

We view software engineering as a team endeavor, and partake in fun and collaborative engineering practices like technical tea times, pair and mob programming, and hobby/game nights—including work-hour Game Times.

In a typical month, a Senior Product Engineer at OneSignal might:

  • Solve challenging business use-cases in a project with elegant, readable code and clear tests
  • Propose a technical investment to make our systems faster, safer, more maintainable, or better in another way you’re passionate about—then drive it forward with your colleagues.
  • Iterate with product on product specs and designs, weighing in not just on feasibility but on opportunities driven by great tech.

Skills & Experience:

  • Modern client-side development expertise with TypeScript + React or an equivalent
  • Modern server-side development expertise with Ruby + Rails or an equivalent
  • A passion for mentoring junior and mid-level software engineers to achieve technical excellence together
  • Experience breaking down complex technical challenges into easily understandable tasks and working with a team to drive projects forward
  • 4+ years software engineering experience building consumer or business applications

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.
