Job description

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
