Job Description
CENSUS, a globally recognized cybersecurity firm delivering top-tier IT and OT security solutions, is hiring a Junior AI Engineer for a full-time, fully remote position based in Europe. This role invites engineers to join the AI team to build, evaluate, and ship production-ready, security-relevant artificial intelligence systems and products. The position suits professionals with a background in machine learning who want end-to-end ownership of features spanning data collection, evaluation, deployment, and iteration.
The person chosen for this role will design LLM-based capabilities, work on retrieval-augmented generation and agent tool-routing systems handling real security data, fine-tune open models, and help guide interns on the team. Candidates will collaborate alongside world-class security and AI experts, receiving mentorship and regular code reviews during their first months. The position provides a clear advancement path toward an AI Engineer title as responsibilities grow to encompass larger and less defined tasks.
Responsibilities
- Design, build, and ship LLM-based features along with corresponding evaluations

- Scope individual tickets alongside a mentor and provide before-and-after results for changes
- Review peer pull requests and assist in guiding team interns
Requirements
- Minimum of one year of practical experience in AI, machine learning, or data science engineering
- Demonstrated history of shipping at least one ML or LLM feature into production or a shared codebase
- Proficiency in Python with tested, readable code
- Familiarity with team codebases utilizing Git, pull requests, and code review processes
- Hands-on experience building and evaluating LLM applications beyond basic API calling
- Solid understanding of machine learning fundamentals, experimental design, and objective result analysis
- Working proficiency with SQL and Docker
- Ability to work independently on scoped tickets and communicate early when blocked
- Strong written English communication skills and the habit of supporting claims with evidence
Qualifications
- Experience fine-tuning large language models using LoRA, SFT, or DPO
- Background in GPU training or model-serving technologies such as vLLM
- Familiarity with vector databases, cloud platforms, or Kubernetes
- Published research papers or prior research experience
- Graduation with a Bachelor's, Master's, or PhD in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or a related field
- Interest in cybersecurity or cryptography
Core Skills
Benefits
- Assigned AI-team mentor for the initial months of employment
