Machine Learning Engineer — LLMs, Retrieval and MLOps for NATO with security clearance
WLG The Hague, South Holland, Netherlands
Financial Services · 2-10 employees
About the role
You will design, build, and maintain end-to-end machine learning pipelines and AI components within a secure, production-oriented environment. This includes managing data extraction, model evaluation, and ensuring the reliability and traceability of AI systems in service.
What they look for
Requirements
The role requires a strong background in software engineering applied to AI, with hands-on experience in MLOps, LLMs, and retrieval-augmented generation. Candidates must be capable of working within secure development practices and possess proficiency in Python, containerization, and database management.
Full description
A multinational defence organisation is building its own applied AI capability, andis looking for an engineer who can take a model all the way into service. You would work on realdatasets and real problems, own the pipeline around the model as much as the model itself, and doit inside an environment where reliability and traceability matter more than novelty.
What you would be doing
- Bringing machine learning and data science methods to new datasets and new questions, andjudging honestly how well the result performs and how good the data underneath it is.
- Finding what is wrong in models, pipelines and datasets, and fixing it in ways that survivecontact with production.
- Designing, writing, testing, documenting and refactoring the programs, scripts and AIcomponents the capability is made of.
- Working to the engineering standards and secure development practices of the organisation, sothat what you build can be maintained by someone else.
- Supporting the whole lifecycle: gathering what is actually needed, choosing how the teamworks, and automating build, test, release and monitoring.
- Defining AI modules for integration, producing the build definitions and validating finishedmodules against agreed functional, quality, security and performance criteria.
- Building and improving the data pipelines that feed all of it, including extraction,transformation and loading work.
- Keeping colleagues informed — progress, risks and blockers — and sharing delivery ownershipthrough reviews rather than handovers.
- Watching what is arriving in the field and contributing to technology assessments, roadmapsand internal knowledge sharing.
What you would bring
- Hands-on history of developing, optimising, deploying and maintaining complete AI pipelines,including training, packaging, monitoring and lifecycle management.
- Strong programming alongside the machine learning: software engineering discipline applied toapplied AI work.
- A solid grasp of model evaluation — how performance is measured, how it is assessed and how amodel is actually improved.
- Practical use of pre-trained and foundation models, large language models and generativetechniques on problems that needed solving.
- Retrieval-augmented generation, embeddings, vector stores and production agent backends, withframeworks such as LangChain, LlamaIndex or Pydantic AI.
- MLOps in earnest: version control, continuous integration and delivery, experiment and modellifecycle practice, automated build and release.
- Backend craft — REST services and modern Python with FastAPI, Pydantic or similar.
- Containers and orchestration: Docker, Kubernetes, Helm, cloud provisioning, and workfloworchestration such as Airflow or Argo.
- Guardrails and operational control for language-model systems: observability, logging andmonitoring that tell you when something has drifted.
- SQL and NoSQL databases, and enough TypeScript, Node.js or Next.js to meet the front endhalfway.
- Nice to have: experience of working in secure, restricted or disconnected environments.
Extensions are offered where the work goes well. Applications are reviewed as theyarrive.
