Kaspar& — Building the future of investing and retirement in Switzerland

Kaspar& is a fast-growing Swiss FinTech building the infrastructure for the next generation of

investing and retirement solutions.

Our mission is simple: make investing and retirement savings radically accessible.

Through our platform, users can access our white-label investment and pension solutions to

automatically invest into ETFs and retirement products. B2B partners on the other side can plan

individual investment and retirement solutions for their clients and generate an entire new

investment experience. Our goal is to make saving and investing as effortless as buying a coffee

on the way to work.

We work with banks, insurance companies, and pension providers — and our products already

serve thousands of users across Switzerland.

The role

We believe great products are built on top of great infrastructure.

At Kaspar&, automation, reliability, and scalability are not nice-to-haves — they are core to our

business model. We serve mass-market customers, which means our systems must be efficient,

resilient, and built to scale from day one.

We are looking for a Backend Software Engineer (Junior to Mid-level) who wants to help us build

and scale critical backend systems powering financial products used by thousands of real users.

You will work on core backend services, observability, and infrastructure foundations — and help

us scale our platform to the next level.

📍 Based in Braga (Portugal) — hybrid setup possible.
