The Engineering team is by far the largest at Swan. This team includes Software developers, who build payments and end-customer applications, as well as Infrastructure, DevOps, QA and Security.

Swan has a diverse team of engineers from all over the place. Co-building is at the heart of the way we work. We believe in challenging each other. We believe that the values of honesty and frankness, while respecting others and showing empathy, are the best way to working together and get things done in a healthy environment.

Methodology

At Swan, we build a product that is mainly designed to be consumed by other engineers. As such, we expect Engineers to take a real role in co-building the product we offer, proposing ideas and challenging what’s doable.

To facilitate this, Engineers are split into independent squads of 4 to 8 engineers working alongside dedicated Product Managers. They build together the roadmap on a quarterly basis and are able to iterate on it in cycle of 2 to 4 weeks.

Because the stability of our system is important, we expect engineers to come up with technical projects that help us scale and to add them to the roadmap like we would any feature.

Our product

Swan makes it extremely easy for anyone to embed banking features, whether they’re a dev or an entrepreneur (or both). It’s exciting to build a bank that can be integrated by anyone! We’d love for Swan to become the reflex for European engineers who want to build something with banking and payments.

The banking domain is a fascinating and challenging place to grow your skills. It’s state-of-the-art and covers everything you’ve learned at school: security, consistency, and scalability, but building a “bank” is a lot different from building another type of startup. In banking sector, you can’t compromise on product quality and leave issues unresolved. That’s why Swan puts security and robustness first and foremost. Join Swan and you’ll be pushed to reach the highest standards of quality and precision.
