For information about how we use your data for recruitment purposes please see our detailed policy here: https://massive.co/recruitment-data-policy/
You operate at the level where architecture becomes a question of judgement, not just technique. You make Android platform decisions that hold up over years, document them clearly, and bring other engineers along with you. You are credible across multiple Android teams because you do the work and you say what you actually think — not because of your title.
Required
-
8+ years' software engineering experience with at least 3 years at Principal, Lead, or Architect level
-
Substantial production experience with Kotlin and modern Android development, with working command of Java
-
Deep architectural understanding of the Android platform — lifecycle, memory, threading, performance, accessibility
-
Demonstrated experience leading architecture on cloud-connected, high-availability consumer applications
-
Substantial experience with cloud platforms (AWS, Azure, or GCP) and how mobile apps interact with them
-
Demonstrated technical leadership without people management — code quality governance, mentorship, architectural decision authority
-
Comfortable communicating complex Android technical topics to non-technical stakeholders
-
Familiarity with Agile methodologies and DevOps practices
Valued
-
Experience across multiple Android surfaces — phone, tablet, connected TV (Android TV / Fire TV)
-
Background in OTT, video streaming, or B2C consumer apps at scale
-
Experience with React Native or other cross-platform mobile frameworks
-
Familiarity with sports / media tech sector
-
Experience with media-specific concerns — video playback, DRM, encoding
-
Experience mentoring senior engineers (not only juniors)
-
Experience working in a global, distributed team environment
Who Thrives Here
Principal Android engineering at Deltatre is technical authority without distance from the code. You are still the engineer who can sit down with a stuck team and work through the problem with them. You are also the person who can sit in a room with product leadership and explain, in their language, why the architectural choice that looks expensive this quarter is the cheap one for next year.
People who thrive in this role tend to be honest about technical trade-offs (they don't oversell solutions or under-warn about risks), generous with their reasoning (they explain why, not only what), and patient with the long-arc work where the value of a decision becomes visible only over multiple Android releases. The role asks for deep Android expertise plus the patience and credibility to influence other engineers without managing them.
Process and what to expect
Salary starts from €30,000 at entry level rising to €90,000 for those with significant relevant experience. Where you land depends on the experience and expertise 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: a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
-
1-hour Technical round of Interview: we will deep dive on your experience and collect examples of the responsibilities you've been dealing with in your past experience. A chance to deep dive on the role and for you to ask questions.
-
1-hour Competency Based Interview: we will ask you 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. Tell us what would work for you.
