Radiant Security is building the most advanced AI SOC platform, featuring unbounded alert triage, investigation, and response for security teams at scale. Our platform ingests alerts from across an organization's entire security stack (SIEM, EDR, identity, cloud) and uses AI to triage, investigate, and surface what actually matters. We're replacing alert fatigue with clear signal, so analysts can focus on real threats.
We're a small, fast-moving team. We ship continuously, stay close to customers, and hold ourselves to a high standard. Our product touches the daily workflows of security teams, and decisions we make have a direct impact on how quickly threats get resolved.
Join us and boost your career with hands-on AI experience.
The RoleThe frontier of applied AI isn't in research labs — it's in production systems solving hard problems under real constraints. As a Staff AI Engineer, you'll be at that frontier, shaping how an entire AI engineering team builds, evaluates, and scales agentic technology in one of the most technically demanding domains there is: cybersecurity.
This role is for engineers who think in systems. You'll own the architecture that underpins every pipeline the team ships — defining how agents are designed, how data flows through complex DAGs, how models are evaluated and swapped, and how the whole system holds together under production load. But you'll also be the person other engineers turn to when a problem is novel, a design decision is hard, or a new capability needs to be pioneered.
The best technology decisions in this space haven't been made yet. You'll make them.
What you’ll do:Architecture & System Design- Own the end-to-end architecture of agentic pipelines: how agents are structured, how data flows between them, how pipelines are composed and versioned, and how the system scales under operational demand. Define the structural patterns for DAG-based agent orchestration. Drive decisions on LLM selection, tool use, retrieval-augmented generation, and memory/state management at the system level.
- Lead multi-engineer projects from technical scoping through delivery, coordinating across engineering, product, and security domain experts. Set best practices for prompt versioning, agent evaluation, dataset curation, and production monitoring. Identify and resolve systemic quality or reliability issues across the pipeline portfolio before they become production incidents.
- Mentor AI Engineers on prompt optimization strategies, experimental rigor, and pipeline design patterns. Conduct design reviews and provide actionable, constructive technical feedback. Identify skill gaps across the team and contribute to hiring, onboarding, and growth planning. Foster a culture of empirical decision-making — every significant change is hypothesis-driven, measured, and documented.
- Stay ahead of the LLM and agentic AI landscape; assess emerging models, frameworks, and techniques for applicability to the team's roadmap. Partner with cybersecurity leadership to translate domain needs into technical requirements and influence the product roadmap.
- Strong programming skills; 8+ years of experience building and deploying production services end-to-end.
- Extensive experience designing and shipping production AI/ML systems at scale.
- Deep expertise in LLM-based agent architectures, including multi-agent orchestration and complex pipeline design.
- Demonstrated ability to lead technical projects involving multiple engineers and cross-functional stakeholders.
- Strong command of evaluation methodologies: statistical testing, benchmarking, regression detection, and metric design.
- Excellent written and verbal communication — able to present complex technical decisions to both engineering and non-engineering audiences.
- Track record of raising the engineering bar on a team through mentorship, standards, and tooling.
- Domain experience in cybersecurity, threat detection, or security operations.
- Experience with large-scale data pipelines and MLOps/LLMOps infrastructure.
- Background in founding or significantly growing an AI engineering function.
- Published work, open-source contributions, or conference presentations in the AI/ML space.
We’re a startup and we make decisions quickly. Our process is designed to give you the best glimpse of our team and allow us to evaluate your technical and culture fit.

What We Do
Radiant Security is a SecOps platform that enables the SOC to leverage the power of AI to streamline and automate analyst workflows. This dramatically boosts SOC analyst productivity, detects significantly more real attacks by deeply investigating every incident, and drastically reduces response times. Radiant’s AI-powered SOC co-pilot automates alert triage and incident investigation to provide unlimited capacity and to detect more real attacks. Incidents are escalated to analysts decision ready— with a complete root cause analysis and full incident scope: including affected users, hosts, applications, etc., and data stitching to follow attacks across data types. Radiant automatically generates a response plan to address each identified security issue, which can be executed manually by analysts, interactively with one-click response actions, or in a fully automated mode. The result is highly accurate triage and investigation that can scale indefinitely to handle any volume of alerts
