Software Engineer - Developer Experience (Go) in London

Paddle offers digital product 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 6000 software sellers in 245 territories globally.

The DX team at Paddle is focused on making Paddle a world-class experience for developers integrating our billing platform. We do that by owning the systems and tooling that underpin how sellers connect to Paddle, from the APIs and SDKs they use every day, to the notification infrastructure that handles tens of millions of events, to the authentication services that power every seller interaction.

We're looking for a Go engineer to join our team. You'll work on some of the highest-traffic and highest-stakes services in Paddle, alongside a cross-functional team of engineers, product managers, technical writers, and designers. This isn't a supporting role; you'll take real ownership of features and systems from day one, and grow into leading medium-sized projects as you find your footing.

If you care about building reliable systems at scale, have strong opinions about what makes an API actually good to build against, and want your work to directly shape how thousands of developers experience Paddle, this is the right place.

What you'll do:

• Write Go and own features across our core backend services: webhooks, email notifications, authentication, and our app marketplace.
• Build and maintain SDKs that help thousands of developers integrate Paddle faster.
• Help mature our API practices and processes, reviewing API changes, improving consistency, and ensuring we don't ship things we'll regret.
• Work with AWS services (ECS, SQS, EventBridge, and more) to keep Paddle's infrastructure performant and reliable.
• Perform code reviews and contribute constructively to your teammates' work.
• Contribute to documentation, both internal and developer-facing, so the knowledge you build doesn't stay siloed.
• Work closely with engineers, product managers, and technical writers to shape what great developer experience actually looks like at Paddle.

We'd love to hear from you if you:

• Have strong backend engineering experience with Go as your primary language. Our interview is Go-based.
• Have a good grasp of API design principles and what makes an API actually pleasant to build against.
• Have experience building and maintaining services in production, you've been on the receiving end of an alert and know what it takes to keep things stable.
• Can take a medium-complexity problem, break it down, and deliver it independently with limited oversight.
• Have a product mindset. You think about the developers who will use what you build, not just whether it compiles.

We'd also love to see:

• A curiosity about AI and how it's reshaping software development, someone who's already exploring it in their day-to-day.
• Comfort working with AWS infrastructure and the services commonly found in event-driven, high-throughput systems.
• Experience contributing to or maintaining SDKs, open-source libraries, or other developer tooling.

We'd be especially excited if you:

• Have hands-on experience with distributed systems and the failure modes that come with them.
• Are genuinely excited about AI, not as a buzzword, but as a real part of how you think about building better tools for developers.
