Job Description

What do we do?

Paddle offers SaaS companies a completely different approach to their payment infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we’re a Merchant of Record for our customers. That means we take away 100% of the pain of payment fragmentation. It’s faster, safer, cheaper, and, above all, way better.

We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North and serve over 3000 software sellers in 245 territories globally.

The role:

As a Senior Software Engineer on either our Retain or Integrations teams, you will play a key role in solving some of the most interesting technical challenges and opportunities we face with our Retain and Metrics products. You’ll be instrumental in improving the product experience for our customers; for scaling our application to service tens of thousands of companies providing us terabytes of data; for integrating Retain and Metrics with the Paddle Core system; and for implementing our exciting new product vision of using AI and machine learning to increase our customers’ revenue — automatically.

You’ll collaborate with multiple teams, alongside engineers, product managers, and designers. You’ll get involved in a wide range of areas which will provide you with plenty of opportunities to develop your own skills and ultimately grow your career as a valued member of the engineering team.

Tech stack:

  • Python (Django) for our Retain and Metrics monolith.

  • Docker in production and local development.

  • Kubernetes to orchestrate our containers.

  • RabbitMQ for our asynchronous message queues.

  • Redis for key/value store.

  • MySQL, Postgres and S3 for persistent data storage.

  • Terraform for infrastructure management.

  • Grafana and InfluxDB for monitoring.

What you'll do:

  • Engineer high-performance background workers for consuming queues

  • Design robust, scalable systems that process terabytes of data

  • Develop high traffic APIs used by hundreds of thousands users per month

  • Practise DevOps, you’re responsible for getting your code to production and supporting it

  • Use the latest AWS services available to run your code

  • Help design a stable platform to support phenomenal growth

  • Mentor and coach other engineers

  • Play a part in an agile team, either kanban or scrum as needed

We'd love to hear from you if you:

  • You have a development background with Python

  • You have experience designing and building systems to handle high traffic at scale in a cloud-based environment in AWS

  • You enjoy collaborating with our technical and non-technical departments

  • You proactively find ways to improve the code and team processes

  • You have a strong understanding of the development process - from design through to deployment, maintenance, and what that means for day-to-day development

  • You take pride in what you build

  • You are interested in what new tools and techniques you could introduce to us!
