Data Engineer – Cost Index Optimization

Engineering | Odense, Denmark | Full-Time

Jeppesen ForeFlight builds software that airlines and pilots around the world rely on every day. From our Odense office, you'll join an international engineering organization where your work has a direct, measurable impact on airline fuel efficiency and emissions.

Own the data platform behind a new flight optimization engine

We're hiring a Data Engineer for a new team building our next-generation Cost Index Optimization (CIO) product. Decoded flight recorder (QAR) data arrives from upstream providers — everything after that is yours: the lakehouse, data quality, per-tail training datasets, and the savings reporting our airline customers see.

What You’ll Do

Build the data lakehouse (Iceberg/S3, Bronze/Silver/Gold layers) for flight data at fleet scale

Own data quality at the ingestion boundary — automated validation of inbound QAR data, including duplicate detection, date/route checks, and cross-checks against independent sources like ADS-B

Build per-tail training and validation datasets and the feature engineering layer for the modeling team

Build the savings reporting framework that quantifies fuel and cost savings per customer fleet

Support large-scale reprocessing as models, parsers, and quality rules evolve

What We’re Looking For

Strong data engineering experience with Python, SQL, and a modern lakehouse or warehouse stack (Iceberg, Delta, or similar) in production

Experience running pipelines on AWS (S3, batch processing/orchestration, infrastructure as code)

A data-quality mindset — you treat validation as a product feature, not an afterthought

Comfort working with large volumes of noisy sensor or time-series data

Interest in aviation is a plus; domain expertise is not required
