Core Platform Engineer

Core Platform Engineer Think in agents. Build the core. Apply to build the future of intelligent systems About Lyzr AI Lyzr is building the foundation layer for agentic AI systems — making it radically simpler to build, deploy, and scale intelligent agents in production. We believe the future of software is agent-first. Not wrappers. Not demos. Real systems that reason, act, observe, and improve over time. We’re looking for Core Engineers who want to work at the deepest layers of agentic infrastructure — the runtime, orchestration, memory, tool execution, and guardrails that power real-world AI systems. If you’re excited by how agents actually work under the hood , this role is for you. Role Overview As a Core Engineer at Lyzr, you’ll work on the heart of the platform — the framework and services that enable agents to plan, execute, collaborate, and operate safely at scale. You’ll collaborate closely with product, infra, and leadership to ensure architectural clarity, technical rigor, and production-grade reliability across everything we ship. What You’ll Work On Build and evolve the Lyzr agent runtime (planning & execution loops, memory systems, tool/function calling, multi-agent coordination) Develop core agent services (event-driven orchestration, RAG pipelines, Text-to-SQL, tool invocation layers) Design secure tool execution environments and sandboxing mechanisms Implement model & data integrations (LLM providers, embeddings, vector stores, connectors, RAG pipelines) Build observability & guardrails (tracing, token-level logging, eval harnesses, safety filters, policy enforcement) Ship multi-tenant SaaS and enterprise / on-prem deployments with RBAC Own scalability & resilience (profiling, load testing, autoscaling, failure handling) Contribute to open-source components and help build a strong developer ecosystem around Lyzr What We’re Looking For Platform Engineering Fundamentals Strong hands-on backend engineering experience Excellent command of Python, FastAPI, MongoDB, and Docker Proven experience building and scaling systems from scratch Solid grasp of distributed systems, system design, and API architecture AWS experience required (Azure is a plus) Product-minded engineers with strong ownership and initiative Clear communicator and collaborative problem-solver Role Bands & Expectations Staff Core Engineer Designs and owns entire complex systems end-to-end Deep expertise in distributed systems and scalable architectures Owns core agent architecture: orchestration, tool execution, memory, RAG, Text2SQL, guardrails Strong cloud, CI/CD, monitoring, logging, and tracing experience Research-driven mindset — pushes the platform forward with new ideas Mentors engineers, leads design reviews, sets quality standards Demonstrated track record of building impactful systems Senior Core Engineer Leads development of key systems within the agent stack Strong system design and clean architecture instincts Ships high-quality components quickly and reliably Mentors junior engineers and collaborates deeply across teams Comfortable operating in cloud-native environments Core Engineer Ships well-scoped features with quality and speed Strong Python fundamentals (Go or Rust is a bonus) Familiar with AWS and CI/CD workflows Breaks down complex problems, identifies edge cases, and asks the right questions Why Lyzr? You’ll work on real agentic systems, not demos You’ll shape the core intelligence layer, not just applications You’ll have ownership, trust, and freedom to build You’ll influence how enterprises adopt agentic AI globally Department Product Locations Bengaluru Remote status Hybrid
