Descripción de la vacante

PhysicsX Ltd. is building a production-grade Agentic platform to power AI-driven engineering workflows, with a focus on safety, observability, and scalable deployment.

You will lead architectural decisions and deliver robust, enterprise-grade solutions that enable product teams, field engineers, and customers to compose advanced AI workflows safely. The role blends platform engineering with AI research, operating in a hybrid model that combines time in our Shoreditch office with work-from-home

Formación

• Platform & Backend Foundations: 4+ years of experience in Platform Engineering, Backend, or SRE.
• Strong proficiency in Python/Go, Kubernetes, Docker, and IaC (Terraform).
• Agentic & AI Engineering: Production experience designing Agentic architectures (chains, tools, memory).
• Familiarity with Agentic frameworks (LangGraph, PydanticAI) and patterns like durable execution.
• Understanding of LLM-specific lifecycle issues: non-determinism, systematic evals, and token-based cost tracking.

Responsabilidades

• Agent Observability: Own the implementation to enforce deep tracing, granular cost tracking, and observability across the lifecycle.
• Agent Deployment: Deliver an intuitive deployment lifecycle which simplifies auth, discoverability and resource requirements.
• Agent Sandboxing: Architect secure environments to isolate and allow agents to operate safely.
• Agent Evals: Implement a stack that empowers domain experts to annotate traces, turning qualitative feedback into quantitative, reproducible evaluation datasets.
• Agent Governance: Implement robust identity and access patterns to ensure agents can safely and correctly act on behalf of users in a regulated enterprise environment.
