Senior AI Security Engineer — red team for LLM APIs

Nordlys Defense Tech is hiring a Senior Senior AI Security Engineer — red team for LLM APIs on the AI security team (Hybrid · Stockholm, Sweden). This is a hands-on role in LLM & generative AI—not a generic “AI enthusiast” post.

You will own LLM features, retrieval, agents, and evaluation end to end: problem framing, offline evaluation, safe rollout, and iteration from production signals. Success is measured with clear metrics (quality, latency, cost, or business KPIs)—not slide decks alone.

Nordlys — Threat modeling for agentic workflows, prompt injection testing, and secure deployment patterns.

Stockholm hybrid.

Nordlys Defense Tech needs someone who can move LLM features, retrieval, agents, and evaluation from experiment to production—with tests, monitoring, and stakeholder-ready communication.

The AI security group partners closely with product and domain experts; you will translate ambiguous requirements into measurable ML or LLM outcomes.

What you will do

• Design and ship LLM features, retrieval, agents, and evaluation with offline evals, dashboards, and rollback plans.
• Improve datasets, labeling, and metrics that correlate with user or business outcomes.
• Review model changes for safety, bias, latency, and infrastructure cost before wide release.
• Document decisions so on-call, support, and compliance teams can act without guesswork.
• Join design reviews and pairing sessions with engineers and domain experts.

What we look for

• Demonstrated production use of core skills such as Python, Kubernetes, AWS, LangChain—with repos, writeups, or metrics we can verify.
• Comfort operating the listed toolchain (Docker, Automation) in real environments—not tutorials only.
• Ownership of at least one feature or model from design through post-launch review—including failure modes you handled.
• Clear communication on trade-offs (quality, cost, latency, safety) with product and non-technical stakeholders.
• Eligible to work in Sweden (or remote policy as stated in the listing).

Benefits & ways of working

• Parental leave, pension, sauna Fridays optional.
