• Data & Orchestration: Build pipelines and serving layers that power adaptive, real‑time features.
• Collaboration: Partner with other engineering teams to ensure performance and reliability.

• Proficiency in Python modern API frameworks such as FastAPI or Flask.
• Hands‑on experience with CI/CD pipelines (we use GitLab) and infrastructure‑as‑code (we use Terraform).
• Practical experience delivering AI/ML features – RAG, orchestration, embeddings, or agentic workflows – in production.
• Commitment to engineering quality – you design for reliability, testability, and long‑term maintainability.

Bonus points if you have:

• Experience with LLM and orchestration frameworks (LangChain, LangGraph, Hugging Face, PyTorch).
• Familiarity with data processing and analytics tools (PySpark, Polars, or Parquet).
>A habit of turning new discoveries into reusable knowledge for the team.

Why This Team

• Impact with purpose – build AI that protects people, not just data.
• Collaborative culture – small, high‑ownership teams that ship fast and learn together.
• Modern stack – Bedrock, LangGraph, FastAPI, PyTorch.
• Continuous learning – budgets for certifications, conferences, and dedicated exploration time.
• Transparency and trust – radical candor, low ego, high accountability.
• Global scale – your work will help protect users across 70,000+ organizations.

Ready to Join Us?

If you’re passionate about building the systems that make AI safe, scalable, and genuinely useful, come help us protect people from the threats technology alone can’t solve.
