• 10+ years of professional software or platform engineering experience.
• Deep expertise in Python, including building production services and shared libraries used by others.
• Hands-on experience with modern AI systems, including LLM integration, RAG, embeddings, and applied generative AI patterns.
• Strong background in machine learning engineering, including model deployment, monitoring, evaluation, and lifecycle management.
• Expert-level understanding of FastAPI, Flask, or similar frameworks, and REST/gRPC service design.
• Strong proficiency with cloud-native development on AWS, GCP, or Azure.
• Minimum 5 years of containerization and orchestration experience (Docker, Kubernetes).
• Production experience with CI/CD pipelines, version control, and modern DevOps practices.
• Demonstrated ability to own large, ambiguous problems and deliver high-value, high-quality solutions.

Nice To Haves

• Experience shaping engineering culture or influencing architectural direction across teams.
• Experience with generative AI tooling (e.g., LangChain, LlamaIndex, PydanticAI, or similar).
• Strong understanding of deep learning frameworks (PyTorch, TensorFlow).
• Experience with distributed systems (Akka, Flink, or similar).
• Prior work building platforms rather than one-off applications.
• A track record of pragmatic decision-making, balancing innovation with maintainability and long-term value.

Responsibilities

• Platform Strategy & Architecture Lead the design, development, and evolution of internal developer platforms tailored for agentic AI use cases, focusing on self-service capabilities, intelligent automation, and an optimized developer experience for building and deploying AI agents.
• Define architectural patterns and best practices for infrastructure, agent deployment and lifecycle management, and operational excellence, ensuring security, scalability, and cost-efficiency across agentic AI workloads.
• Evaluate, select, and integrate foundational agentic AI technologies, including cloud-based agent orchestration frameworks, container orchestration (Kubernetes), infrastructure-as-code (IaC) tools, agent workflow orchestration platforms, and observability solutions for agentic AI systems.
• Drive the adoption of platform-as-a-service (PaaS), infrastructure-as-code (IaC), and agent-as-a-service principles to standardize and automate environment provisioning, agent training, and agent serving.
• Cloud Infrastructure & Agentic AI Operations Architect, deploy, and manage core infrastructure and platform services on cloud platforms (GCP preferred), leveraging agentic AI and ML services such as Vertex AI, Compute Engine, GKE, and Cloud Storage.
• Design and implement advanced networking, security controls, and access management (IAM) for agentic AI systems, supporting compliance and responsible AI guidelines.
• Establish and manage comprehensive monitoring, logging, tracing, and alerting systems for agent workflows, models, and applications, ensuring the reliability, performance, and health of both platform and hosted agentic AI solutions.
• Developer Experience & Agentic AI Tooling Build and maintain robust CI/CD and agentic AI pipeline automation (e.g., GitLab CI/CD, Jenkins, Kubeflow, ArgoCD) for automated testing, deployment, release management, and agent lifecycle management.
• Develop internal tools, APIs, and services that abstract agentic AI infrastructure complexity, enabling application and data science teams to self-service their agent/agent group training, deployment, and monitoring needs.
• Champion best practices for code quality, testing, security scanning, and automated deployments, integrating agentic AI-assisted developer tools (e.g., GitHub Copilot, Claude Code, Gemini CLI) into platform offerings.
• Provide guidance and support to engineering and data science teams on leveraging platform agentic AI capabilities to improve development workflows and operational posture.
• Backend Engineering for Agentic AI Platform Services Develop scalable backend services and APIs using Python, specifically designed to power agentic AI platform functionalities and developer tools.
• Design and implement REST-compliant or gRPC endpoints with versioning, comprehensive error handling, and clear documentation (e.g., OpenAPI/Swagger) for agentic AI platform services.
• Architect database schemas and manage data persistence for platform metadata, agent artifacts, configuration, and telemetry data.
• Build secure, high-performance services capable of handling demanding internal agentic AI platform workloads.
• Cross-Functional Collaboration Partner closely with application, data science, security, and operations teams to understand agentic AI needs, gather feedback, and evolve the platform to meet enterprise requirements for agent-based solutions.
• Contribute significantly to enterprise architectural decisions for agentic AI infrastructure and lead technical planning efforts for complex agentic AI platform initiatives.
• Conduct thorough code and agent review, define platform engineering standards, and champion best practices for reliability, security, and operability of agentic AI systems across teams.
• Clearly document platform architectures, agentic AI API specifications, runbooks, and critical technical decisions for knowledge sharing and maintainability.
