One method, many products

This is a senior role, and not one we can hire junior into — you are the first, for a while the only, and the platform everyone else builds on is the one you put in place.

Mainloop is an engineering company in Barcelona. We own what we build and we answer to ourselves. You get the interesting part of a new company, with a real customer and real products from day one.

What we build is the software that automates professional-services work — across roughly fifteen countries, for businesses drowning in process. We build those products and we run them. That second half is why this role exists,



and it is not a formality: a team that owns how its software is built should own how it ships.

You are the person who ends that. You are our first DevOps engineer, and for a while our only one.

What the job actually is

You are not inheriting a platform. You are writing one.
