ABOUT OUR CUSTOMER

It is a European company building exciting new products from scratch for startups and helping mature companies in their journey towards data-driven innovation and AI-based solutions. Their expertise spans EnergyTech, FinTech, ClimateTech, and more.

Founded in Ukraine and developed based on Scandinavian culture, HBM is hiring both in Ukraine and the EU. We combine the agility of a startup with a human-oriented leadership team and a strong focus on work-life balance.
 

PROJECT OVERVIEW

Our customer is a leading Icelandic energy company providing electricity, geothermal water, and carbon storage. We are looking for a Middle Data Engineer with a focus on support and optimization.

Unlike a typical "build-from-scratch" role, this position is centered around maintaining and stabilizing a complex DWH ecosystem. You will be the "guardian" of data flow, ensuring that daily operational pipelines run reliably and investigating failures in the legacy and modern stack.
 

TECH STACK

• Platforms: SQL Server, Azure
• BI Stack: Microsoft BI (SSRS, SSIS, SSAS — Olap and Tabular), Power BI, Tableau
• Tools: TimeXtender, exMon (monitoring)
• Languages: SQL (primary), Python, PowerShell
   

CHALLENGES & RESPONSIBILITIES

• Pipeline Troubleshooting: Investigating failed ETL tasks, timeouts, and execution errors.
• Root Cause Analysis: Identifying why data extractions from in-house systems (like SCADA) fail and fixing them.
• Monitoring: Working with exMon to resolve warnings and ensure data consistency in business-critical tables.
• DWH Maintenance: Correcting configuration issues in pipeline parameters, schedule triggers, or source/target connections.
• Collaboration: Working closely with the Icelandic on-site team and the Data Engineering Lead in an Agile environment.
• Documentation: Updating Jira tickets with clear English descriptions of problems and resolutions.
   

REQUIREMENTS

• Experience: 3–5 years of commercial experience with DWH solutions and data pipelines.
• SQL Mastery: Strong debugging skills, specifically with MS SQL Server.
• ETL Expertise: Solid experience with ETL/ELT workflows (SSIS, ADF, or similar).
• Analytical Mindset: Ability to parse log outputs, identify root causes, and correct code-level issues.
• DWH Concepts: Deep understanding of fact tables, dimensions, and staging layers.
• Soft Skills: Proactive "action-oriented" approach and the ability to communicate effectively with stakeholders.
• Language: Upper-Intermediate or Advanced English.
• Location: You are a Ukrainian currently residing in Europe.
   

NICE TO HAVE

• Experience with Python or PowerShell for data processing and automation.
• Background in the Energy sector or working with IoT/SCADA data.

RECRUITMENT PROCESS

1. HR Interview (30 min)
2. Managerial Interview (30 min)
3. Technical Interview (1.5 hours)
4. Customer Interview (30–45 min)
    

WE OFFER

• Long-term engagement with a stable Icelandic partner.

Requirements:
A Full-Stack Craftsman: You are an expert in Ruby on Rails and TypeScript, capable of building everything from complex dashboards and billing UIs to sleek documentation platforms.

The "DevEx" Champion: You have a natural empathy for other developers. You’ll develop deep knowledge of our platform (Pub/Sub, Chat, LiveSync) and use the product yourself to gain a first-hand understanding of the developer experience.

Comfortable with Ambiguity: You thrive in high-level vagueness. You can take a feature from a loose concept to a shipped product with minimal hand-holding, identifying problems and proposing solutions independently rather than waiting for a roadmap.

Accountable & Reliable: You take pride in high-quality, well-tested code. You meet your delivery commitments, provide realistic estimates based on technical complexity, and communicate proactively if a timeline is ever at risk.

An Owner: You monitor what you build in production and take personal ownership of quality issues. You see a feature through its entire lifecycle, from the first line of code to the final metric.
