Who Thrives Here
We are looking for people who bring rigour and curiosity to their work in equal measure. You take quality seriously — not as a constraint, but as a standard you set for yourself. You communicate clearly, flag issues early, and treat your colleagues' time and context with respect. You are honest about what you know and what you are still learning.
This is an environment that rewards initiative. If you are looking for genuinely interesting engineering problems on a technically demanding platform, with colleagues who hold themselves to a high standard, this may be exactly right.
Not sure which level is right for you? Apply anyway and tell us where you think you sit. We'll figure it out together.
Process and what to expect
Salary starts from of €30,000 at entry level rising to €90,000 for those with significant relevant experience. Where you land depends on your experience, technical background, and the stack you bring. If your expectations sit outside the range, tell us anyway —we're happy to have an open conversation. Internal progression is assessed through a structured process combining a technical assessment and a competency-based interview. The role falls under CCNL Commercio| D.Lgs. 96/2026
Assessment stages:
-
Introductory conversation: this is a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
-
Take-Home Assessment: we have a coding challenge waiting for you, to grab a sense of what you'll be dealing with. This step is the entry point in our process, and mandatory to acccess to the followng steps.
-
1-hour Technical round of Interview: we will use your Assessment as a starting point for a discussion with Senior team members in the video team. You will do code review and discuss additional technical aspects in details. This conversation, combined with the output of the assessment will allow us to make a solid technical evaluation.
- 1-hour Competency Based Interview: we are going to ask you some situational questions around how you deal with real-life scenarios at work. Easier doing it, more than explaining it!
If any of these formats would be difficult for you, tell us — we adjust regularly and can usually accommodate.
Accessibility and accommodation questions are welcome at any stage, including before you apply. Tell us what would work for you.
