# Senior Data Engineer - Real Time Streams

> Globaldev Group · Ukraine (Remote) · Full-time · Posted 2026-08-25

**Workplace:** remote

**Department:** Dream Team

## Description

You will be a senior engineer on the team that owns the real-time data platform. The platform turns operational events (orders, driver locations, geofence transitions, shifts, MQTT session events) into live analytics, routing inputs, and warehoused data across Postgres/TimescaleDB, ClickHouse, and BigQuery. You will own the platform end-to-end: design, implementation, deployment, and production operation of the streaming jobs, CDC pipelines, Kafka Connect bridges, and downstream sinks that move this data.

### Responsibilities 

\- Designing, implementing, and operating stateful Apache Flink streaming pipelines: keyed state, windowing, watermarks, timers, side outputs, custom sources/sinks.

\- Designing, developing, deploying, and maintaining Change Data Capture (CDC) pipelines using Flink CDC or Debezium, moving operational database changes into the streaming platform with correct snapshot/incremental handling, schema evolution, and downstream idempotency.

\- Building and operating Kafka and Kafka Connect pipelines: topic and partition design, source/sink connectors in distributed mode, schema and converter management, and deadletter routing.

\- Owning the path from Kafka → Flink → Postgres / TimescaleDB / ClickHouse / BigQuery, including schema design, idempotency strategy, batch tuning, and observability.

\- Diagnosing and fixing production issues: checkpoint failures, backpressure, state growth, sink slowness, autoscaler oscillation, restart loops.

\- Hardening the platform: delivery guarantees, watermarks, DLQ handling, schema migrations, alerting coverage. \* Code reviews and mentoring mid-level engineers.

\- Contributing to the deployment side: Helm charts, ArgoCD applications, GKE configuration, Grafana dashboards, Prometheus alert rules.

\- Influencing direction: state backend choices, schema migrations, when a pipeline needs to be split or rebuilt.

### Requirements

\- 5+ years of professional software/data engineering experience, with strong Java expertise.

\- Production experience with Apache Flink and stateful real-time streaming pipelines.

\- Strong Apache Kafka experience, including Kafka Connect, consumer groups, partitions, delivery guarantees, and schema management.

\- Hands-on CDC experience using Debezium or Flink CDC.

\- Experience designing and operating Kafka → Flink → database/data warehouse pipelines in production.

\- Strong understanding of PostgreSQL and experience with at least one analytical database such as ClickHouse or BigQuery.

\- Experience with Kubernetes and deploying/operating production data workloads.

\- Proven ability to troubleshoot and optimize production streaming systems—backpressure, checkpoint failures, state growth, latency, lag, and sink performance.

\- Strong understanding of data consistency, idempotency, schema evolution, and observability.

\- Ability to work independently and own a data platform component end-to-end, from design through production operation.

### Will be a plus 

\- Experience with TimescaleDB, hypertables, and time-series data.

\- Experience with PostGIS and geospatial/spatial query optimization.

\- Deep ClickHouse performance tuning, including MergeTree and partitioning strategies.

\- Strong BigQuery optimization and data modeling experience.

\- Experience with Flink Kubernetes Operator and Flink autoscaler tuning.

\- Experience with ArgoCD, Helm, GKE, Prometheus, and Grafana.

\- Experience designing high-throughput, low-latency real-time systems at scale.

\- Experience with MQTT or IoT/event-driven systems.

\- Knowledge of Kafka Schema Registry, Avro/Protobuf, and advanced schema evolution.

\- Experience mentoring engineers and leading technical decisions around streaming architecture.

\- Experience with routing, logistics, delivery, mobility, or location-based platforms would be particularly relevant.

### What we offer 

\- 20 days of paid vacation, 5 sick days, and public holidays.

\- Flexible schedule with a high level of autonomy.

\- Opportunity to influence product and technical decisions.

\- Professional growth and learning opportunities.

\- Comfortable working environment with a supportive team.
