The Sr.ETL is the "Captain" of a single squad. This is a squad leader role focused on delivery predictability, technical excellence, and day-to-day execution. You are a Senior+ Engineer who manages people, not a manager who used to code; if you cannot open the IDE and debug a production issue, you cannot perform this role.

Meet the Job

• Delivery Mastery: Optimize the team’s "Idea to Production" cycle time and strengthen delivery predictability.
• BS Detector: Use your technical depth to spot unrealistic estimates, fragile designs, or risk blind spots.
• Hands-on Leadership: Spend ~50% of your time on system design and ~20% on hands-on development like code reviews and unblocking technical issues. 
• Conflict Resolution: Mediate interpersonal or cross-team conflicts early to protect team cohesion and delivery.
• Talent Density: Team growth performance calibration, involved in hiring , and succession planning for your squad of 6–9 engineers.
• Emergency Response: During critical incidents, jump in technically or coordinate the response effectively.
• AI-Native Engineering: Lead the adoption of agentic tooling, LLM workflows, and AI automation within your team to accelerate the development lifecycle.

How About You?

• You have 5+ years of experience and have shipped production code recently. Web, Mobile, Backend (Angular, Kotlin, Swift, Python, …)
• You have an explicit desire or experience leading people but remain an active technical contributor.
• You possess high emotional intelligence and resilience under pressure.
• You are a strong unblocker who translates and synthesizes rather than just relaying messages.
• You are based in Madrid and open to coming into the office once a week.
