Founding Engineer (w/m/d)
SkalarTL;DR
Founding Engineer.
Build v1 -> v10. Join the early core team of experienced entrepreneurs (scaled to millions of users, $100m+ exits). Build the future of tax & accounting with AI. Ship features end-to-end, influence the stack, and lay the foundations for scale. Grow into leadership as we expand across countries. Above-market pay + meaningful equity.
The opportunity
How taxation, accounting and payroll work today is a pain for everyone. Still every business must do it continuously. It is the backbone that our economy runs on.
Enabled through AI, we are turning this often-painful process into a radically simple experience for our customers, so they can focus on what matters to them: growing their business.
About us
We are a team of experienced entrepreneurs who have scaled businesses to 10s of millions of users, 10s of millions in revenue, multiple countries, and 9-digit exits - and we are just getting started. We are backed by leading venture investors and expanding rapidly.

Your work will be the driving force behind our revolutionary customer experience, enabled through AI, offering radical simplicity to our customers.
