Job description

You will work on the core of NeuroStrike: multi-agent orchestration, tool use, model evaluation and fine-tuning of open-weight models that run on European infrastructure. Your work directly decides how many real vulnerabilities we find and how reliably we prove them.

• Design and improve agentic workflows: planning, tool calling, memory and context management
• Build evaluation harnesses and benchmarks that measure real exploitation success
• Fine-tune and serve open-weight models (SFT, preference and RL-based methods)
• Optimise cost, latency and reliability across multiple model providers
• Turn engine traces into high-quality training data

• You must be willing and eligible to be authorised for classified information at BEGRENSET / NATO RESTRICTED level, and to undergo security clearance (sikkerhetsklarering) under the Norwegian Security Act if a customer assignment requires it. This is required due to the nature of our customers.
• Professional experience building production systems on top of LLMs
• Strong Python and/or TypeScript skills
• Hands-on experience with evaluation — you measure before you claim an improvement
• Understanding of model limitations: hallucination, prompt injection and tool-use failure modes
• Professional working proficiency in English
