Full Stack Engineer

Team: Engineering Commodities

Location: Athens

Commitment: Full-time

Workplace Type: hybrid

Key Responsibilities

Lead end-to-end integration architecture: Drive the full engineering lifecycle—from external feed ingestion and domain modeling to streaming, entity resolution, and UI distribution.

Design robust ingestion & entity-resolution systems: Map incoming barge data onto Kpler reference data (vessels, zones, installations, products) using existing Elasticsearch and PostgreSQL matching patterns.

Build scalable Kafka streaming pipelines: Construct event-driven contracts, schemas (Avro), deduplication mechanisms, and dead-letter queue replays with Python and Scala.

Deliver data across customer surfaces: Surface integrated barge data cleanly across Elasticsearch read models, external APIs, data warehouse feeds, and the Kpler Terminal (TypeScript/Vue).

Champion production quality & observability: Maintain full operational ownership of your services, setting SLOs, participating in on-call rotations, and driving post-incident improvements.

Ensure data integrity & analyst alignment: Validate external feeds and integrate human-in-the-loop analyst workflows so corrections seamlessly apply to barge movements.

Mentor and elevate engineering craft: Guide and mentor crew members, document architectural designs, and actively contribute to decomposing legacy estates into event-driven services.

Experience & Background

What you'll need (Must-haves)

• Production data engineering experience: ~5+ years of experience designing, operating, and maintaining data-intensive production systems with full ownership.

• Advanced Python & SQL expertise: Proven ability to build clean, well-bounded services within large, complex, and evolving codebases.

• Event-driven streaming proficiency: Hands-on experience with Kafka streaming in production, including schema management (Avro/Schema Registry), deduplication, and replay patterns.

• Third-party integration & entity resolution: Demonstrated background integrating external data feeds, managing schema mapping, and building data quality monitoring frameworks.

• Operational mindset: Direct experience managing production observability, writing documentation, and resolving incidents in a distributed system environment.

Nice-to-haves

• Functional programming & Scala: Experience or familiarity with Scala (Kafka Streams) or a track record of rapidly mastering new languages.

• Geospatial & domain knowledge: Familiarity with geospatial data tools (PostGIS) or exposure to maritime, logistics, or commodities domains.

• Modern data stack exposure: Experience with Elasticsearch, Airflow, Snowflake/lakehouse table formats, Kubernetes, and GitOps deployments.

• UI/Frontend collaboration: Working knowledge of TypeScript or Vue to collaborate on user-facing terminal features.
