The Role
Handshake is building the infrastructure layer that powers the next generation of AI agents across our platform. As a Software Engineer on our Agentic Infrastructure team, you’ll be at the forefront of AI at Handshake, architecting and building the foundational systems that allow AI agents to plan, execute, and operate autonomously at scale. This is a rare greenfield opportunity to define how an AI‑first company builds for the agentic era — at the intersection of infrastructure, AI, and direct product impact.
- Architect & build the core agent orchestration layer — including tool use, memory, and multi‑step reasoning systems — that powers AI‑driven features for 20M+ users & 1M+ employers across Handshake’s platform
- Design evaluation, observability, and reliability frameworks that ensure agent behavior is safe, auditable, and production‑ready at scale
- Establish engineering standards for agentic development across Handshake’s platform teams, enabling every engineer to build with AI
- Partner with ML, product, and platform engineers to ship agent‑powered features from infrastructure to production at Olympic pace
You Have
Must‑Haves:
- 2-4 years of backend engineering experience, with strong proficiency in NodeJS, Typescript, and/or Python
- Experience designing and operating distributed systems at significant scale for developer experience
- Hands‑on experience building with LLM orchestration frameworks (LangChain, LlamaIndex, or similar)
- Deep understanding of agent architectures: tool use, multi‑step reasoning, memory management, and evaluation
- Experience with cloud infrastructure (AWS, GCP, or Azure) and infrastructure‑as‑code tools like Terraform
- Experience with Node, JavaScript, CI/CD, Docker
- A track record of shipping production systems with high reliability, low latency, and strong observability
- Strong communication skills and ability to drive alignment across engineering and cross‑functional partners
Bonus Points:
- Open‑source contributions to LLM or agent frameworks
