Virtue AI is looking to build the essential guardrails and red-teaming tools that enable organizations to deploy multi-modal AI applications confidently and responsibly

Requirements

  • Strong backend and cloud engineering skills and experience building developer-facing libraries, APIs, or tools
  • Strong product sense for internal platforms: you think in interfaces, reusability, and team velocity
  • Experience building ML infrastructure or tooling for training, tuning, and inference workflows
  • Comfortable working with systems like Sagemaker, Vertex AI, Kubernetes, Ray, or similar distributed compute environments
  • Strong familiarity with the ML development lifecycle and tools like W&B, HuggingFace, MLFlow, DVC, or custom registries
  • Proficiency in Python (strongly preferred) and cloud infrastructure
  • Experience with containerized deployment patterns (e.g., Docker, Helm charts) and infrastructure abstraction

Responsibilities

  • Develop SDKs, CLIs, APIs that expose platform capabilities (training & fine-tuning pipelines, inference stacks, feedback loops, quantization, and deployment) in a consistent, developer-friendly way across heterogeneous environments (e.g., Vertex AI, GKE, Together.ai)
  • Design and build core components of our ML platform, including model registries, experiment tracking integrations (W&B), and cataloging systems for red-teaming, guardrails and agentic datasets and models
  • Create tooling that supports reproducibility, version control, and benchmarking of models and datasets across internal R&D, on-prem and SaaS
  • Build robust abstractions over infrastructure (e.g., Vertex AI, Ray, Kubernetes), enabling ML practitioners to run jobs and deploy models without needing to understand low-level infra
  • Develop and maintain internal libraries that integrate with CI/CD, model tracking, QA, and security/compliance review workflows
  • Implement lightweight and performant observability tooling across training and inference platforms (e.g., GPU utilization and performance (accuracy, latency, throughput) regressions)
  • Help define the model packaging and deployment interfaces used across our on-prem (Helm, Docker, HuggingFace, Github Actions) and cloud environments

Other

  • Collaborate with security and compliance stakeholders to ensure platform tools are secure, tenant-aware, and audit-ready
  • Support internal onboarding and usability by contributing to platform documentation, quickstarts, and dev support workflows
  • Virtue AI, Inc. is an Equal Opportunity Employer
