Senior Data Engineer (m / f / d)

As a Senior Data Engineer, you will lead the development and evolution of our company-wide data platform for flight data. You will play a central role in shaping how flight logs are collected, processed, stored, and analyzed across R&D, production, testing, and customer support.

You will join our Data Engineering & Cloud team (currently 5 engineers) and take technical ownership of the data platform, setting direction, defining best practices, and driving architectural decisions.

Working closely with stakeholders in Ukraine and Germany, you will enable teams to extract reliable insights from large-scale flight telemetry and push the boundaries of drone technology.

This is a hands-on leadership role combining system design, implementation, and technical mentorship.

Own and lead the development of the flight data platform, from ingestion to analytics

Design, build, and maintain scalable back-end systems for tool-based flight data analysis used across R&D, production, and support

Architect and manage robust, high-performance database solutions for large volumes of time-series and telemetry data

Define and implement data pipelines, APIs, and cloud infrastructure to support automated analysis and testing

Continuously improve system reliability, performance, and observability

Expand and maintain automated test suites and data quality checks

Collaborate closely with cross-functional teams to translate domain needs into technical solutions

Act as a technical mentor, promoting engineering best practices within the team
