Principal Engineer - AI

Most boards and executives are currently flying blind when it comes to cyber risk. They are guessing. At Safe, we've built an AI-driven engine that finally gives the C-Suite a clear, quantified, and real-time view of their security posture. We don't just provide data; we provide certainty.

We are a $170M Series C-funded category leader. We don't play in the mid-market; we operate at the highest levels of global enterprise. Today, we are proud to serve 10% of the Fortune 500, protecting global icons such as Apple, Netflix, AT&T, Verizon, and Victoria's Secret.

As we scale toward our next chapter, we are looking for high-performers who want to do the best work of their careers at the intersection of AI and Cybersecurity.

The Culture Memo: Our Operating System

Safe is not a typical corporate environment. We are a high-intensity, mission-driven team. We value builders who want to define a category and work alongside people who are equally committed to excellence.

• Extreme Ownership: We don't do not my job. We hire people who see a gap and own the solution from start to finish.
• The Elite Standard: We serve the most sophisticated companies on the planet. Our work must be bulletproof. Whether it's a line of code or a sales deck, we aim for Tier-1 quality every time.
• Methodology & Rigor: We don't wing it. From Force Management and MEDDICC in sales to data-driven sprints in engineering, we rely on proven frameworks to stay disciplined and predictable.
• Radical Candor: We move too fast for politics or sugar-coating. We value direct, honest feedback that helps us find the right answer quickly.
• The Series C Hustle: We have the stability of a well-funded leader but the heart of a startup.
  
  

The Perks & Ownership:
We want our team to feel like owners because they are owners. We trust our people to manage their results and their time.

• Meaningful Equity: Every Safestar is a shareholder. You aren't just an employee; you are a partner in our success.
• Unlimited Leaves: We don't believe in clock-watching. We offer unlimited leave because we trust you to take the time you need to recharge while staying committed to the mission.
• Comprehensive Benefits: We provide top-tier medical insurance and wellness benefits to ensure you and your family are well cared for.
• Career Trajectory: We are growing aggressively. For high-performers, the path for advancement moves at the speed of your ambition.
  
  

As a Principal Engineer - AI, you will define and lead the technical direction of AI systems that power Safe's CRQ, CTEM, and TPRM products, including agentic workflows, RAG pipelines, LLM orchestration, and AI-native developer tooling. You'll be the hands-on architect behind Safe's AI engineering stack, bridging model intelligence with production-grade infrastructure.

You'll collaborate with product, data, and platform teams to design scalable, explainable, and enterprise-ready systems.

This is a high-impact, technical leadership role that will shape how AI is built, deployed, and governed across Safe.

Core Responsibilities:

• Architect Safe's AI Systems: Design and scale AI-driven components — LLM orchestration, retrieval-augmented generation (RAG), vector stores, prompt pipelines, and AI microservices. Drive architecture for AI observability, safety, and evaluation (precision, recall, F1, hallucination detection, cost metrics)
• Productionize AI Agents: Build multi-turn, goal-oriented agent systems that automate reasoning across TPRM, CTEM, and CRQ domains (e.g., control reviews, issue RCA, automated responses). Ensure reliability, traceability, and deterministic behavior in production
• AI Infrastructure & Platform Ownership: Partner with Platform & DevOps teams to operationalize model serving (AWS SageMaker, Bedrock, or self-hosted Llama), build AI APIs, and manage model lifecycle and versioning. Establish feature stores, embedding management, and in-memory retrieval layers
• Data Pipeline & Knowledge Graph Integration: Work with Data Engineering to design pipelines for structured and unstructured data ingestion, semantic indexing, and context retrieval (Snowflake + Iceberg + LlamaIndex)
• AI Evaluation, Monitoring & Governance: Define internal frameworks for golden dataset validation, LLM evaluation (LangFuse/LangSmith), and safety enforcement policies. Implement human-in-the-loop (HITL) mechanisms and continuous feedback loops
• Mentor & Multiply: Guide AI and backend engineers on architectural design, experimentation methodologies, and prompt optimization. Collaborate with product leaders to translate abstract AI goals into measurable engineering deliverables
  
  

Minimum Qualifications:

• Experience: 12+ years total experience in software engineering, including 4+ years building AI/ML systems or large-scale data/LLM infrastructure
• Core Technical Skills:
• Strong programming fundamentals in Python, Go, or TypeScript
• Deep understanding of LLM-based architectures, prompt engineering, and RAG pipelines
• Hands-on experience with LangChain, LlamaIndex, or equivalent orchestration frameworks
• Vector databases (FAISS, Pinecone, Weaviate, Redis Vector, or Milvus)
• Cloud model deployment (AWS SageMaker, Bedrock, Vertex AI, or custom inference APIs)
• Data systems: Snowflake, Iceberg, S3, Postgres/MySQL
• MLOps & Infra: Familiar with model versioning, CI/CD for ML, and performance optimization for real-time inference
• Applied AI Focus: Practical understanding of evaluation metrics, hallucination detection, RAG reliability, and enterprise AI safety
  
  

Preferred Qualifications:

• Experience integrating AI into cybersecurity or risk management products
• Familiarity with multi-agent systems and autonomous workflows (CrewAI, LangGraph, AutoGen)
• Experience building AI evaluation dashboards and AI observability stacks
• Knowledge of knowledge graphs, semantic search, or retrieval pipelines
• Exposure to data governance, compliance, or SOC2/ISO 27001 environments
• Published research, open-source contributions, or prior leadership of AI teams is a strong plus
