Senior DevOps Engineer
Build a company's entire delivery platform from the first commit, own it outright, and never carry a pager. This is a senior role and it is not a role 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 a new engineering team inside an established international group . We are in Barcelona, we are being built from scratch this year, and we have the backing, the customers and the product portfolio of a company that has been around for decades. You get the interesting part of a new team without the part where you check whether payroll clears.
The group has been running a tech lab in Casablanca for more than eight years — Barcelona is its second, built to sit closer to the teams we build for, and AI-native from the first commit, because it starts from a blank page. What we build is the software that automates professional-services work — across roughly fifteen countries, for businesses drowning in process. 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 our first DevOps engineer, and for a while our only one.
You are writing one.
Hosts, networking, ingress, access, environments — committed, parameterised, reviewable. Make deployment self-serve. Commit to production, an automated test gate, per-branch preview URLs a stakeholder can open from their phone, and a rollback that everyone on the team has rehearsed before they need it.
We are hiring at senior level precisely so that those decisions can be yours — the platform every product here runs on is the one you put in place, and we would rather bring in the judgement than supervise it.
No rota, no pager, no phone number, no "just keep an eye on it this weekend". If something breaks at 3am on a Saturday, or in the second week of August, it gets fixed the next working morning. Plenty of ads say "healthy on-call
