Applied AI Engineer (CyberSecurity)

• We are seeking an Applied AI Engineer to build the customer-facing cyber service and use‑cases on top of our cyber harnesses
• You will turn “we have agents” into “we shipped something a client uses
• “ This role is about composing red‑team/blue‑team agentic workflows, configuring harnesses for real‑world scenarios, and delivering value directly to clients
• Your work will bridge the gap between our foundational cyber harnesses and the agentic solutions that clients deploy
• While SWE‑Cyber makes the platform robust and scalable, and Pentesters run the solution and guide the direction, you will focus on building the agentic use‑cases and client‑facing service that solve real security problems
• Client‑Facing Agentic Solutions
• Compose red‑team / blue‑team agentic workflows for production use‑cases
• Configure harnesses for cloud defense, vulnerability scanning, dynamic red‑teaming, and penetration testing scenarios
• Work directly on client use‑cases, translating security requirements into agentic solutions
• Turn prototype agents into deployed services that clients rely on
• Context Engineering & Orchestration
• Design and implement context engineering that enables agents to operate effectively in cybersecurity domains
• Orchestrate multi‑agent systems for complex security workflows
• Build the agentic layer that sits between the harness and the client
• Service Delivery
• Ship fast and iterate based on client feedback and real‑world performance
• Operate independently while leveraging internal building blocks and frameworks
• Collaborate with pentesters to ensure domain accuracy and effectiveness
• Partner with SWE‑Cyber to ensure the platform supports your use‑case requirements
• In certain specific situations, we will also consider remote candidates based in one of the countries listed in this job posting — currently France & UK. In that case, we ask all new hires to visit our local office:
• For the first week of their onboarding (accommodation and travelling covered)
• Then at least 3 days per month

Some cyber context is a real plus, but not mandatory - we can pair you with pentesters for domain depth. You ship fast, with a bias toward action and delivery. Excellent communication skills and collaborative attitude. Operate independently with a customer‑led mindset. Strong applied AI engineer with hands‑on experience building agents, LLM orchestration, context engineering, evals, and RAG systems. Strong problem‑solving abilities and attention to detail. Able to reuse internal components and bricks effectively. Genuine cyber or pentest knowledge. Experience building agentic harnesses or multi‑agent systems end‑to‑end. Strong background in evals and benchmarking of agent systems. Experience with security tooling or workflows. Prior work on production AI systems in regulated or high‑stakes environments.
