Data Engineer

<p>Our Data Engineers work in environments where data comes from multiple sources, moves between different systems or requires reliable structuring before it can be used. They handle both the implementation of new architectures and the evolution, stabilisation or takeover of existing data flows.</p>

<p>Here is what a MySpecialist Data Engineer can handle:</p>

<ul>
<li><strong>Data collection and integration</strong> : connecting applications, APIs, files, databases and external services to centralise data from heterogeneous sources.</li>
<li><strong>Data pipeline design</strong> : building and evolving ingestion, transformation and loading flows required to move data between different systems.</li>
<li><strong>Data transformation and structuring</strong> : preparing, normalising, enriching and organising data to provide consistent and usable datasets.</li>
<li><strong>Data warehouses and data lakes</strong> : designing, feeding and evolving environments used to centralise analytical or operational data.</li>
<li><strong>Data quality and reliability</strong> : implementing controls to identify missing, inconsistent, duplicated or non-compliant data.</li>
<li><strong>Processing orchestration</strong> : managing dependencies, execution sequences, schedules and recovery processes required for automated data processing.</li>
<li><strong>Data flow monitoring</strong> : monitoring executions, analysing errors, handling incidents and identifying failures or anomalies within pipelines.</li>
<li><strong>Processing optimisation</strong> : analysing execution times, volumes, queries and resource usage to improve data processing performance.</li>
<li><strong>Data architecture evolution</strong> : adapting pipelines, models and infrastructure when new sources are introduced, volumes increase or data usage evolves.</li>
<li><strong>Data migration and recovery</strong> : preparing and executing migrations between databases, platforms or environments while controlling transformations and data integrity.</li>
<li><strong>Data availability</strong> : preparing data required by reporting tools, BI teams, analysts, business applications or data science use cases.</li>
<li><strong>Existing environment takeover</strong> : reviewing existing pipelines, processing systems and architectures to identify dependencies, anomalies, performance limitations and required developments.</li>
</ul>

<p>Assignments may involve building a new architecture, making existing data flows more reliable, evolving a platform, migrating data or taking over an environment that has become difficult to maintain. The scope adapts to the systems, volumes, data sources and technical constraints already in place.</p>
