Backend Engineer, Agents
Lapel, San Francisco
About the job
At Lapel, we believe the most hospitable companies win. We're building the data, infrastructure, and tools that help customer-facing teams understand every customer and act on that insight at scale throughout the entire customer lifecycle.
Most internet businesses want to treat customers well, but their tools work against them. We’re building the layer that makes every interaction feel personal again: unifying context, coordinating action, and closing the gap between intent and experience.
It’s a technically ambitious challenge spanning data infrastructure, AI, and systems design – with a deeply human outcome: helping software companies serve people better. We call it hospitality at scale.
We’re well-funded, backed by top-tier investors, and already working with exceptional companies, from fast-growing startups to large enterprises. We’ll share more details when we talk.
About this role
You’ll own the systems that power long-horizon agents at Lapel: how they remember, retrieve context, reason over customer history, use tools, take actions, and improve over time. This includes the memory, orchestration, observability, evaluations, and internal frameworks that make agents reliable across our products.
