Developer

As a Developer / Data Scientist in our Data Analytics team, you will play a pivotal role in building out our analytics capabilities. You will be working alongside our Statistician and Lead Data Scientist to identify opportunities to develop and leverage new applications. You will get the opportunity to put your expertise to the test rapidly on use cases such as:

• Supervised and unsupervised forecasting models and algorithms
• Master and reference data/entity mapping
• LLM fine-tuning and entity-recognition + data extraction
• Data visualization/reporting

We are looking for your expertise in building and deploying models and end-to-end pipelines that significantly impact our client products, solutions, and engagements. You must have experience with machine learning and AI, but you will have access to our existing colleagues' vast knowledge in that space. Ideally, you are conversant on data modeling and can act as a partner to our architecture team to accelerate the delivery of our solutions to our AWS cloud-based environment. Success in this role means delivering production-ready models that are actively used in client-facing tools, building stable and scalable data pipelines with clear documentation, and enabling faster team iteration through reusable components and streamlined data flows. A successful experience at the intersection of machine learning and organizational psychology or social sciences is a plus. LOCATION AND TEAM STRUCTURE

• Joining the Amsterdam office.
• Collaborating very closely with our Lead Data Scientist.
• Providing technical expertise and 'coding' mentorship to data analysts.
• Collaborating closely with our architecture team.
• Interacting routinely with the broader Data Analytics and client teams (Head Data Analytics, Practice Leaders, Innovation team…)., * Collaborate with the data analytics team and other stakeholders to identify and prioritize opportunities for innovative D&A applications.
• Develop, test, and deploy machine learning models, entity mapping models, and reporting solutions (including NLP and AI technologies).
• Design and implement data pipelines and APIs that facilitate seamless data circulation across teams and systems.
• Stay abreast of industry trends and advancements in data science, ensuring our approaches and technologies remain at the cutting edge.

Do you have a Master's degree?, * Advanced degree in Computer Science or Data Science.

• Demonstrated ability to take ownership of data science projects from ideation to deployment with an emphasis on machine learning, NLP, and AI technologies (along with a strong understanding of their applications and limitations).
• Strong programming skills in Python and strong familiarity with ML frameworks (e.g., TensorFlow, PyTorch). Bayesian modelling experience is very valuable.
• Although not required immediately, some background and/or keen interest in developing a skillset in data visualization for reporting is considered very valuable (JS libraries such as Chart Js, C3/D3.js, Plotly or similar).
• Excellent analytical and problem-solving abilities, with a keen eye for detail and accuracy.
• Strong communication and interpersonal skills, with the ability to convey complex concepts to non-technical stakeholders.
• Self-motivated with the ability to work independently and as part of a team in a fast-paced environment.

PREFERRED QUALIFICATIONS

• Prior experience in consulting or working closely with business stakeholders.
• Direct experience developing and deploying models in NLP and LLM applications, particularly those that enhance client-facing tools or internal knowledge workflows.
