Core Platform Engineer

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.

Were 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 youre excited by how agents actually work under the hood, this role is for you.
• Role Overview
• As a Core Engineer at Lyzr, youll work on the heart of the platform — the framework and services that enable agents to plan, execute, collaborate, and operate safely at scale.
• Youll collaborate closely with product, infra, and leadership to ensure architectural clarity, technical rigor, and production-grade reliability across everything we ship.
• What Youll 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 Were 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

• 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

• 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

• Youll work on real agentic systems, not demos
• Youll shape the core intelligence layer, not just applications
• Youll have ownership, trust, and freedom to build
• Youll influence how enterprises adopt agentic AI globally
