OneSignal, Inc.; United Kingdom; Remote; GBP 50,000 - 90,000

Job description

OneSignal is a leading omnichannel customer engagement solution, powering personalized customer journeys across mobile and web push notifications, in-app messaging, SMS, and email. On a mission to democratize engagement, we enable over a million businesses to keep their users - including readers, fans, players and shoppers - engaged and up to date by delivering billions of messages daily.

1 in 5 new apps launches using OneSignal! We support companies in 140 countries, including Zynga, USA Today, Bitcoin.com, Eventbrite, Tribune, and many more - from startups and small businesses just getting off the ground to established companies communicating with millions of customers.

We’re Series C, venture-backed by SignalFire, Rakuten Ventures, Y Combinator, HubSpot, and BAM Elevate. We offer remote work as the default option in the United States in California, New York, New Jersey, Oregon, Pennsylvania, Texas, Utah and Washington, as well as in the UK and Singapore - with plans to expand the locations we support in the future. Some roles are hybrid roles and will be listed as such. We have offices in San Mateo, CA and London, UK, and offer flex seating options for employees to work together in-person where we don't have offices.

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.

About The Team:

We have grown rapidly to where we are today serving billions of HTTP requests daily. We achieved this scale by writing scale-sensitive components in languages like Rust and Go. This potent combination of high performance with efficient resource utilization has given us an incredible competitive edge.

We are hiring a Platform Engineer to help us continue to scale by operating and engineering the future of our infrastructure. We are maintaining 99.95% uptime today, and we are investing to ensure we maintain that as the business continues to grow and as the product evolves.

Your primary task will be software engineering with a focus on infrastructure, operations, and automation. You'll be building systems to run our product, improving internal services, and advising product teams on architecture as it relates to the operability of the service.

The systems you'll be responsible for include all of the services which power our product. This ranges from off-the-shelf services like PostgreSQL, Scylla, Redis, Kafka, Kubernetes, etc. to our in-house services such as the Rails web app, various Rust backend services, and our high-performance API layer written in Go.

You'll be working with Kubernetes to automate our data center operations and writing operational services to automate database operations. One of the key challenges in this role is to not only understand systems to the point of being able to manually operate by hand but also to understand in sufficient detail to write software systems to automate such operations.

Your Responsibilities:

• Optimize and Elevate Performance: Identify bottlenecks in our systems and unleash your creativity to introduce cutting-edge optimizations. You'll have the chance to improve the performance of our databases and evaluate innovative storage technologies that will elevate our infrastructure to new heights.
• Forge Infrastructure as Code: Take the lead in setting up robust infrastructure and configuration as code using Kubernetes and Terraform. You'll be at the forefront of shaping our foundational architecture, ensuring it’s both resilient and scalable.
• Drive Observability and Monitoring: Establish and maintain a state-of-the-art observability and monitoring stack. Your insights will enable us to stay ahead of potential issues, ensuring our services remain reliable and performant.
• Craft the Golden Path for CI/CD: Define and implement best practices for continuous integration and deployment. Your work will streamline the deployment process for our engineering teams, allowing them to roll out new features swiftly and safely.
• Collaborate Across Teams: Work closely with various engineering teams to architect highly scalable and observable services. Your collaboration will be essential in creating a cohesive and efficient development environment.
• Be a Key Player in Incident Response: Join the on-call rotation and be a crucial part of maintaining our systems' health. Your expertise will be vital in troubleshooting and resolving issues, ensuring our services always meet the highest standards.

What You'll Bring:

• At least 8 years of platform experience
• Experience operating reliable production systems at scale
• Knowledge of Linux systems internals
• Desire and ability to automate tasks
• Experience in managing PostgreSQL for high-scale throughput systems or similar experience with other relatable SQL datastores.
• Operational experience deploying and managing Kubernetes
• Experience working with Cloud Providers (AWS/GCP/Azure)

We value a variety of experiences, so these are not required. It would be an added bonus if you have experience in any of the following:

• Recently writing Go and/or Rust
• Working with Layers 1-3 of the OSI networking model

Qualities we look for:

• Friendliness & Empathy
• Accountability & Collaboration
• Proactiveness & Urgency
• Growth Mindset & Love of Learning

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 in our workplace.
