As a Software Engineer, you will define features of our ever evolving products - Channels, Chatkit and Beams. You will have strong ownership over these features and have opportunities to blog/talk about them publicly. You will use your experience shipping these features to help prioritise new features and shape our roadmap.

  • You will need to be able to work comfortably solving ambiguous and complex problems
  • Contributing to the full feature lifecycle: ideation, prototyping, releasing, iteration, maturation, sunsetting
  • You will need to dive into both new and familiar areas of our code to support more inexperienced members of your team, and communicate effectively whether it be pair-programming, in a code review, or in a proposal for a new improvement or service
  • Work with our team to refine our product development process. We want to turn the feature development pipeline into a well-oiled machine
  • Helping customers successfully integrate Pusher products into their apps
  • Participating in our on-call rota supporting our operational reliability targets including uptime and latency

We use a modern tech stack. Our services are written in Go and deployed on Kubernetes. Pusher uses and supports many other projects from the Cloud Native Computing Foundation.

We use a wide range of tools and products including languages such as Go and Ruby. Terraform and Puppet for infrastructure management. Jenkins, Travis, Prow for our CI pipeline. Open source tools such as Postgres, Redis, Kafka, all running on Linux and AWS/Heroku. We advocate using whatever is best suited for the task at hand.


What Pusher is like

We are in an extended phase of change and growth: after a period of success as a smaller company, we are learning how to be a successful global company. This process is challenging, rewarding, frustrating, and invigorating, often all at the same time! We are trying to do very big things — at the end of the day, we want to help hundreds of thousands of developers who will impact hundreds of millions of users.

We strongly believe in the importance of diversity and inclusion. For us, diversity means “difference” and inclusion means “making the differences work together” – and the result is a company that strives to practice consistently high levels of belonging. Inclusivity provides a better working environment for all, improves the quality of our services, and positively impacts outcomes. We welcome people of different nationalities, backgrounds, experiences, orientations, ages, abilities, and perspectives.

We are here to help our customers build delightful applications. By solving significant engineering challenges and packaging them into easy to use APIs, we let developers focus on making their users happy. We believe the growing demand for software will greatly improve developer productivity and, in turn, increase the quality of the apps we all use on a daily basis.

We put emphasis on collaboration between people and teams. Everyone is on the same mission, so sharing work helps us reach our goals faster. We strive for transparency. Keeping everyone well-informed is crucial for building trust, efficiency, and satisfaction at work.
