Job description

Senior Software Engineer – Go

Join to apply for the Senior Software Engineer – Go role at Paddle.

What We Do

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

We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North, and we serve over 5,000 software sellers in 245 territories worldwide.

The Role

As a Senior Software Engineer within our Billing group, you will play a key role in developing core areas of our new billing platform. You’ll provide world‑class experiences to thousands of customers who use and trust Paddle every day. You'll take the lead on discovering new features, planning their implementation, and contributing your technical expertise to shape the future of our billing platform.

You’ll collaborate with multiple teams—engineers, product managers, and designers—working across a wide range of areas that will give you plenty of opportunities to develop your skills and grow your career as a valued member of our engineering team.

What You’ll Do

• Design, build, and maintain high-throughput, highly reliable systems that power core Billing capabilities.
• Take ownership of features from initial design through to production, monitoring, and ongoing improvement. Ensuring systems are built with correctness and precision.
• Architect solutions that scale with growing transaction volumes and customers.
• Write clean, maintainable, well‑tested code and set a high bar for code quality and engineering standards.
• Lead design discussions and contribute to architecture decisions, balancing short‑term delivery with long‑term sustainability.
• Work closely with Product Managers, Designers, Data, Risk, and Operations to translate business requirements into robust technical solutions.
• Help shape product direction by providing technical insights, trade‑offs, and delivery estimates.
• Partner with Customer Support or Operations teams to investigate and resolve production issues.
• Support and mentor other engineers through code reviews, pairing, and design feedback.
• Act as a force multiplier by driving best practices and long‑term decisions for our engineering community.
• Contribute to shaping our team and wider engineering culture to ensure Paddle remains an exceptional place to work.

We’d Love to Hear From You If You Have

• A development background with Go.
• Experience designing and building systems to handle high traffic at scale in a cloud‑based environment in AWS.
• Enjoy collaborating with our technical and non‑technical departments.
• Proactively find ways to improve the code and team processes.
• A strong understanding of the development process— from design through to deployment, maintenance, and day‑to‑day development.
• A strong understanding of API principles and best practices.
• A proven track record of bias for action and strong customer focus.
• Excellent communication and collaboration skills; comfortable working alongside both technical and non‑technical stakeholders.
• Proven success working with complex problems and ambiguity, maintaining high standards while balancing progression and perfection.
