Senior System Design Engineer

AI Agent Orchestration Platform

system-design champion

What You’ll Own

You’ll be the engineering force behind the platform’s next evolution. This role is for someone who loves deep system architecture and makes distributed systems behave like butter.

You will:

• Architect & optimize a

  high-scale agentic orchestration runtime

• Design and implement

  ultra-low-latency, high-throughput

  backend systems
• Work with Python + Golang to build core orchestration, scheduling, and messaging layers
• Own performance engineering: profiling, caching, concurrency, queuing, and cold-start optimization
• Partner with our AI team to bring agentic workflows to life (even if you're not an agentic expert today)
• Lead engineering decisions around Kubernetes, multi-tenant SaaS, observability, and cloud infra
• Help build a platform that Fortune 1000 enterprises rely on for mission-critical automation

Who You Are (Ideal Profile)

a system design expert first

You may be perfect if you:

Must-Have Strengths

• 7–12 years building

  high-scale distributed systems

  or real-time platforms
• Deep expertise in

  system design

  ,

  architecture

  ,

  performance optimization

  , and

  scalability patterns

• Hands-on mastery of

  Golang

  and

  Python

• Strong understanding of cloud-native architecture: Kubernetes, microservices, queues, caches, load balancing
• Experience building backend systems that handle large volumes of events, messages, or workflows
• Strong ability to take an ambiguous product architecture and make it clean, reliable, and elegant

Nice-to-Have (Not Required)

• Experience with AI Agent frameworks (LangGraph, AutoGen, CrewAI, etc.)
• LLM reasoning orchestration, workflow engines, or RL-based decisioning
• Knowledge of vector DBs, semantic retrieval, or event-driven AI apps
