Principal Full-Stack Data Engineer

• Lead and shape mission-critical data and ML platforms that power Eneco’s entire energy balancing chain, from long-term forecasting to real-time trading at national scale.
• Operate as a hands-on Principal Engineer who designs, builds, and unblocks complex, cross-team systems while setting the technical standard across data, ML, and platform engineering.
• Have direct impact on the energy transition by modernizing and stabilizing high-stakes, time-series-driven data systems where reliability, governance, and performance truly matter.

At Eneco, we are accelerating the energy transition. With our ambitious One Planet Plan, we aim to be the first energy company to become climate neutral by 2035. That means no more reliance on fossil fuels — and a full focus on smarter, cleaner, and more resilient energy systems.

Achieving this requires data platforms that are reliable at scale and capable of supporting decisions across the entire energy value chain, from long-term forecasting and asset planning to near-real-time trading and balancing. As a Principal Full Stack Data Engineer, you will work on the systems that make this possible, modernizing and stabilizing mission-critical data and ML platforms, improving data quality and lineage, and setting technical standards across teams.

At Eneco, you combine deep technical ownership with real-world impact, working alongside strong engineering and product peers in an environment where engineering excellence directly supports both the energy system and the transition to a sustainable future.

What you’ll do

Eneco is accelerating the energy transition, and resilient, high-quality data systems are foundational to that mission. The energy balancing chain—from long-term forecasting, asset modeling and planning, all the way to short-term intraday trading—relies on reliable, well-architected, and scalable data platforms.

As a Principal Data Engineer, you will operate across multiple engineering domains, collaborating with various platform teams and supporting business-critical initiatives. You will tackle some of the most complex technical challenges in the energy value chain: stabilizing and re-architecting critical data systems, coordinating large engineering projects, improving data lineage and governance, and unblocking projects that impact multiple engineering and business teams.

This is a hands-on technical leadership role, not a conceptual “architect”. You will design, build, review, decide, and guide. You will work closely with Engineering Managers, Staff Engineers, and Product Managers to drive technical clarity and consistent engineering practices across the organization.

You’ll be responsible for

• Driving large-scale system and architecture initiatives across long-term energy planning, long- and short-term trading, including data flows, integration with neighboring systems (provisioning, asset management, reporting), and the ongoing evolution of the data landscape.
• Stepping in to unblock or lead complex engineering efforts—for example, clarifying and redesigning lineage for datasets in a domain, fixing systemic data quality issues, and improving cross-team integrations.
• Shaping and reviewing technical designs, ensuring robustness, scalability, and alignment with Eneco’s enterprise architecture.

Hands-On Engineering & System Design

• Leading the design and implementation of data and ML platforms and pipelines using Databricks, Delta/Unity Catalog, Airflow, dbt, Snowflake, Azure, and related services, applying best practices in data modeling, orchestration, storage, and streaming.
• Modernizing and refactoring legacy data and ML workflows to enhance reliability, transparency in data lineage, maintainability, and management of metadata, lineage, content, and master data.
• Designing and building systems that integrate data and ML pipelines with other platforms and user-facing products, while applying engineering best practices in DevOps, CI/CD, infrastructure as code, observability, and incident management.

Platform & Governance Alignment

• Improving coherence and standardization across teams by promoting common patterns for ingestion, modeling, streaming/batch processing, feature engineering, ML model development, experimentation, testing, and serving.
• Ensuring solutions meet Eneco’s standards for security, compliance, and operational resilience.

Mentorship, Enablement & Cross-Team Collaboration

• Advising and supporting Engineering Managers and Senior Engineering Managers in technical decision-making (e.g., framework selection, architectural direction, build-vs-buy decisions).
• Assisting with planning topics such as team sizing, hiring needs, and sequencing of technical roadmap items.
• Sharing best practices, running design reviews, and coaching engineers to level up the engineering bar across Eneco.

Is this about you?

Must-Haves

• 8+ years of experience in data engineering or software engineering, with at least 3 years in a senior, staff, or principal role driving multi-team technical decisions.
• Deep hands-on expertise with Databricks, Delta Lake/Unity Catalog, Airflow, Snowflake, dbt, and Azure cloud services.
• Demonstrable experience designing, operating, and stabilizing mission-critical, distributed data systems where reliability, correctness, and continuity are essential requirements. Including end-to-end data pipelines, event-driven architectures, and platform integrations.
• Strong understanding of data architecture, data modeling, streaming, data lineage, data quality frameworks, and metadata management.
• Good knowledge across ML engineering, including feature engineering, model lifecycle management, experimentation, performance monitoring, and MLOps.
• Solid knowledge of software engineering and DevOps fundamentals, including CI/CD, infrastructure as code, observability, containerization, API design, and operational excellence.
• Experience with timeseries analytics environment (databases, analytics, processing and modelling).
• Ability to drive alignment across engineering and product teams, especially in ambiguous or high-impact problem spaces.
• Excellent written and verbal communication skills, with the ability to translate technical topics for both engineering and business stakeholders.

Nice to have

• Experience in energy markets, commodity trading, or near-real-time operational systems.
• Experience with forecasting platforms, ML lifecycle design, and integrating data & ML systems into production.
• Familiarity with high-frequency or low-latency data processing patterns.

This is where you’ll work

You’ll work at the core of Eneco’s energy trading and forecasting domain, where data platforms directly support long-term planning, asset optimization, and near-real-time trading decisions. You’ll collaborate across multiple platform teams in a highly technical, business-critical environment, building and stabilizing data and ML systems where reliability, scalability, and governance are essential to keeping the energy system balanced.
