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.
Being frank, but empathetic is the best way to get things done! It’s also more fun.
Your missions.
You will be technically responsible for one or more projects.
You will have the opportunity to solve problems in one of the most demanding IT domains with a reactive architecture.
You will design with the product team the bank by API.
You will improve the performance of a system with a rapidly growing load.
You will ensure the respect of the architecture rules and of the automated tests Our technical environment Kotlin & Scala (JVM) Akka PostgreSQL Kafka Docker K8S AWS Methodology Engineers at Swan are not here to get orders and just start coding, they’re here to co-build.
To get heavily involved with the product.
Swan’s devs collaborate heavily with the product team and are always proposing ideas and challenging what’s doable.
We follow a methodology that’s similar to “Shape up”.
3-week cycles.
Co-building is central to how we work.
Each month, the product and engineering teams work together to plan goals and develop specifications for the next 3 weeks.
During these weeks, we do our best to reach goals, all while planning and designing projects for the next cycle.
1-week cooldown.
After a cycle of building, it’s cooldown week.
We use this time to take care of the remaining tasks and improve tools and processes.
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, you can’t afford to have little bugs (imagine messing up someone’s account statement).
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.
