Job Description

To support our growth, we are recruiting Senior Consultants specializing in Data Engineering solutions. You will lead client engagements, co-design data engineering solutions through close collaboration with clients, manage stakeholders, and ensure impactful project delivery from strategy through execution.

Responsibilities:

  • Google Cloud (GCP): Hands-on experience with Google Cloud computing, data, and AI/ML services, including cloud architecture, compute and storage, IAM, cost optimization, and Infrastructure as Code. Experience applying GCP to data engineering and/or machine learning workloads is required.

  • Cloud & Distributed Systems: Designing and implementing data solutions leveraging modern cloud platforms (e.g., AWS, Azure, GCP) and distributed computing frameworks (e.g., Spark, Kafka).
  • Database Design & Data Modeling: Developing logical and physical data models and optimizing database solutions for various data types and workloads, including relational, NoSQL, time-series, and graph databases.
  • Data Integration & Loading Patterns: Implementing best practices for batch, streaming, and real-time data integration, adapting to structured, semi-structured, and unstructured data sources.
  • CI/CD & DataOps Practices: Enabling continuous integration and deployment of data services and infrastructure, using modern DevOps tooling to ensure reliability, versioning, and automation in data workflows.

Within Sia itself you will:

  • Develop and enhance our Data Engineering offerings through internal training sessions, working groups, and internal/external publications.
  • Represent Sia at professional events, contributing actively to thought leadership initiatives (articles, white papers, webinars).
  • Drive business development by crafting compelling proposals, identifying new collaboration opportunities, and fostering long-term client relationships.
  • Manage client engagements, serving as a trusted advisor and subject matter expert to middle and senior-level management.
  • Supervise and mentor junior to medior consultants, guiding their professional growth, reviewing deliverables, and facilitating the development of technical and interpersonal skills.

Your profile

  • Analytical thinker with a structured and proactive approach.
  • Experienced communicator capable of clearly articulating complex technical ideas to varied audiences.
  • Effective stakeholder manager, comfortable guiding teams through project delivery.
  • Demonstrated ability to mentor colleagues and facilitate professional development.

Qualifications

  • Completed WO Master's degree in Data Science, Econometrics, Applied Mathematics, Computer Science, (Energy) Engineering, or a related technical field involving substantial programming.

  • 3-6 years of relevant professional experience (or equivalent academic research).
  • Strong analytical mindset with systematic problem-solving abilities.
  • You have a strong interest in data and AI-related topics, the ability to quickly build expertise in these areas, and you’re excited about helping our clients seize the opportunities they offer.
  • A fast learner who demonstrates strong communication skills, adaptability, and entrepreneurial drive.
  • Fluency in English, with excellent communication and presentation abilities. Dutch or French fluency is a must.
  • Proven interest in Data Engineering, and relevant sectors such as Energy and Finance.

What do we offer?

  • Competitive salary package, including annual salary increase, bonuses, and flexible mobility options (company car or personalized mobility plan).
  • Tailored training and development opportunities to position you as an expert in your field.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
