Senior Engineer till AOTO

About AOTO

AOTO is a Swedish fintech company building a digital operating system for car dealers, combining inventory financing, automated bookkeeping and digital services like leasing, warranties and insurance in one platform. The goal is simple: help car dealers make faster, smarter decisions and maximise their buy and sell potential.

We're in an exciting early stage as part of the 0TO9 ecosystem, building the product from scratch with clear ambitions to expand across Europe. This role is central to getting us there.

The Role

We're looking for a Senior Engineer who thinks beyond code. You'll shape architecture, own technical decisions and build infrastructure that scales. You're curious, pragmatic and you know that the right technology isn't always the one that looks best on a CV.

What we work with:



Python and SQL/Postgres.



HTMX



AWS core services.

Who you are



Senior backend developer with experience from SaaS or high-growth companies.



You're comfortable in startup environments, fast pace, broad ownership and constant change don't scare you.



You think about the product, not just code, and take responsibility beyond your own tasks.



You prefer simplicity and technology that works over flashy technology that impresses.



You actively use AI tools in your daily workflow (Cursor, Claude Code, Copilot or similar), this isn't a nice to have, it's a must.

Why AOTO?



Join early and help shape a product that's being built from the ground up



Your decisions actually matter, no layers, no bureaucracy



Work closely with CEO Marc Blomberg and CTO Henrik Lagercratz



Grow with the company as we expand into new European markets
