Backend Software Engineer (Core AI)

As a Backend Engineer, you'll work on the core infrastructure that makes our AI platform fast, reliable, and scalable.

You'll be joining the Core AI team, responsible for the foundational layer of our AI product, covering orchestration, memory, low-level security, and system harness.

This is a role for someone who thrives at the intersection of backend engineering and applied AI, thinking about latency, reliability, and model behavior all at once.

What you'll do

You'll be tackling challenges across:

AI orchestration: owning the core layer that coordinates AI workflows, model calls, multi-step reasoning, and multi-agent delegation, including RAG pipelines and knowledge bases

LLM integration: integrating and tuning new LLMs into a production-grade backend, with a focus on security, guardrails, and evaluation (latency, response quality)

Data ingestion & export: building robust pipelines and services to handle a variety of file formats reliably and at scale

Context & token optimization: designing strategies to maximize LLM efficiency, manage context windows, and keep costs in check

Infrastructure & observability: designing scalable APIs, automating deployment pipelines, monitoring, and testing to keep the platform reliable and performant

Architecture & engineering culture: participating in tech stack decisions, documenting technical knowledge, and continuously driving innovation across the AI platform
