Full Stack Engineer

Description:

As a Full Stack Engineer, you will build systems that power a dynamic, ever‑evolving automated red teaming framework and sandboxing for GenAI models with a focus on LLMs, and the pipelines that evaluate those prompts across providers. 

We’re looking for a product‑minded, hands-on developer who is comfortable moving from frontend UX to backend services and has a familiarity with GenAI apps. 

Key Responsibilities

• Build prompt management, versioning, and metadata services
• Implement evaluation runners that execute prompts against multiple model backends (Hugging Face, Amazon Bedrock, Azure) and collect metrics, logs, and failure cases.
• Create analytics dashboards and APIs to compare guardrail effectiveness across models, policies, and releases.
• Design reliable, secure AWS workloads (Lambda, S3, EC2, Step Functions) and SQL pipelines (Athena/Redshift) for data ingestion and reporting.
• Ship production‑quality code end‑to‑end: tests, CI/CD, observability, and documentation.
• Collaborate with AI security researchers to translate red‑team findings into productized workflows aligned with frameworks such as OWASP AI Security, MITRE ATLAS, and NIST AI RMF

Must-Have

• 3+ years programming in Python, React, Node.js/FastAPI
• Experience with AWS (Lambda, S3, EC2; bonus: Step Functions, EventBridge).
• Experience in SQL and data modeling; advantage: Redshift or Athena.
• Demonstrated experience across both frontend and backend development

Nice-to-Have

• B.Sc in Computer Science, Electrical Engineering, Mathematics, or related field.
• Hands-on‑on with Agentic AI frameworks (LangChain, AutoGen) and protocols (MCP, A2A).
• Background in content safety, abuse prevention, or adversarial testing.
