Principal Engineer - Machine Learning

Define API & SDK Standards: Design and establish robust, developer-friendly APIs and SDKs that enable internal engineering teams and external ecosystem partners to build, deploy, and manage complex agent workflows.

Architect Stateful & Memory Systems: Build and optimize stateful dialog management, shared context systems, and memory services for multi-turn, context-aware autonomous agents.

Implement Multi-Agent Communication Protocols: Establish scalable agent-to-agent (A2A) communication protocols, coordination patterns, and shared memory spaces for distributed multi-agent workflows.

Lead Cloud-Native Microservices Migration: Drive the transition toward cloud-native, event-driven backend services using modern microservices, service mesh, and event-streaming architectures.

Optimize LLM Performance & Cost Efficiency: Design and implement LLM orchestration optimizations—including semantic caching, dynamic batching, token monitoring, and intelligent model routing—to ensure high performance and cost governance.

Own Integrations & Observability: Direct the implementation of enterprise RAG pipelines, vector database integrations (e.g., Pinecone, Weaviate, FAISS), and deep LangSmith/OpenTelemetry tracing for end-to-end evaluation and visibility.

Drive Technical Excellence & Mentorship: Establish rigorous standards for automated testing (unit, integration, load), tenant isolation (RBAC, multi-tenancy), and provide technical mentorship to elevate engineering capabilities across the team.

Must Have:

Experience: 12–18 years of progressive software engineering and machine learning system development experience, with a track record of architecting scalable enterprise backend systems.

Technical Mastery: Deep proficiency in Java and Python, with hands-on expertise building production systems using agentic orchestration frameworks (e.g., LangChain, LangGraph, LangSmith) and workflow engines (e.g., Temporal, Airflow).

Distributed Systems Expertise: Advanced understanding of event-driven architectures, microservices, Kubernetes, Kafka, AWS cloud infrastructure, and mixed database paradigms (PostgreSQL, Vector DBs).

Execute with Excellence: Proven ability to navigate ambiguity, solve complex architectural bottlenecks, anticipate technical risks, and connect cross-functional dependencies to deliver high-impact engineering initiatives at scale.

Lead with Vision & Strategy: Demonstrated capability in translating complex business and AI goals into actionable long-term platform roadmaps while influencing technical decisions across cross-functional engineering partners.

Cultivate a Growth Mindset: A track record of identifying innovative tools, challenging assumptions, and driving technical continuous improvement across the broader engineering organization.

Nice to Have

Experience with AI-driven planning systems, dialog state tracking, or reinforcement learning feedback loops in production environments.

Hands-on experience with enterprise security frameworks, including SSO, OAuth2, RBAC, and multi-tenant data isolation.

Active involvement in open-source AI/ML projects or contributions to major LLM/orchestration libraries.

Please note this is a hybrid role that requires an in-office presence 3 days / week (Tue-Thu).
