The Role

We are hiring a Senior Data Engineer to join our Data Platform & Engineering team, reporting to the Head of BI. You will own the source-to-warehouse pipelines on Microsoft Fabric, harden the data-quality layer, and partner closely with the Analytics & Reporting team so that every Group KPI is computed once, correctly, and from a single semantic source. This is a senior individual-contributor role: you will set patterns, mentor mid-level Data Engineers in the team, and have direct influence on the data architecture across all reporting data flows.

Location: Bucharest (hybrid).

Responsibilities

• Design, build, and operate ingestion pipelines from source systems (ERP, CRM, MT5, PSPs and banks, Everflow, BigQuery and multiple other sources) into Microsoft Fabric.
• Own the medallion architecture (bronze → silver → gold) pipeline transformations, including SCD Type 2 dimensional modelling for customer, broker server, product, and partner dimensions.
• Maintain the dbt-style semantic layer that feeds Power BI and Reporting so KPI definitions stay aligned across consumption layers.
• Set and meet pipeline SLAs — NRT, T+1 for the CEO daily pack at 09:00 CET, near-real-time freshness — and publish the Known Issues register when anything misses SLA.
• Optimise Fabric compute and storage cost, monitor capacity headroom, and recommend right-sizing.
• Maintain the data dictionary across bronze / silver / gold / NRT layers, and contribute to the KPI Dictionary as the single source of truth.
• Mentor the team on Fabric patterns, reconciliation discipline, and review craft. Be the engineer the team escalates to when a pipeline misbehaves.

Requirements

• 5+ years in data engineering, with at least 2 years on a modern cloud data platform (Microsoft Fabric, Databricks or equivalent).
• Strong SQL — advanced window functions, query optimisation, ability to read execution plans — and a track record of building production pipelines at scale.
• Hands-on dimensional modelling experience: Kimball patterns, SCD Type 2, fact vs dimension tradeoffs.
• Python for pipeline code, plus experience with at least one orchestration / transformation framework (Fabric Data Pipelines, Azure Data Factory etc).
• Experience operating a streaming or near-real-time layer (KQL / Eventhouse, Kafka or equivalent).
• Strong reconciliation and data-quality discipline — you are comfortable owning a number end-to-end across multiple source systems and standing behind it.
• Git and code-review fluency, with disciplined documentation habits.
• Professional English, written and spoken.

Nice to Have

• Microsoft Fabric specifically: Lakehouse, Warehouse, Eventhouse, semantic-model authoring.
• Experience in a regulated industry — CFD / FX brokerage, banking, asset management, working awareness of CySEC, MiFID II, or equivalent prudential frameworks.
• Power BI semantic-layer authoring and DAX, even at a basic level — enough to speak fluently with the Analytics & Reporting team.
• PostgreSQL logical replication / azure_cdc / Fabric mirroring experience.
• ERP or trading-platform integration experience.
• ML and AI modelling.

Tech Stack

Microsoft Fabric (Lakehouse, Warehouse, Eventhouse), Power BI, PostgreSQL, MySQL, Python, SQL and Git.
