At LapelAt 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 incredible companies, from fast-growing startups to large enterprises. We'll share more details when we talk.About This RoleYou'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. We believe that AI should be used to help scale the human moments and deliver exceptional service across any customer touchpoint. Your job is to build the infrastructure that makes that possible.What You'll DoDesign systems that help agents remember, summarize, and retrieve context across long-running customer interactionsBuild workflows and tools that reduce failure modes and make agents easier to trust in productionSet up the observability and eval infrastructure we use to monitor agent behavior, debug issues, and raise quality over timeHelp to scale multi-tenant systems that keep customer and agent context isolated, reliable, and ready for enterprise useOur StackLapel is built end-to-end in TypeScript in a single monorepo.React, Vite, and Tailwind on the frontend;Node.js and Postgres on the backend;Temporal and Pulsar to power orchestration.We ship quickly, and care about creating a developer experience where anyone can prototype, experiment, and get ideas into production fast.You'll Thrive in This Role If YouHave 3+ years of backend or software engineering experience, with a track record of building reliable systems in productionAre excited to build the systems that make AI agents more useful, dependable, and easier to improveAre comfortable designing APIs, working with databases, and building workflows that run reliably over timeUnderstand system design, debugging, observability, and production reliability at a practical levelAre customer-focused and able to translate product needs into reliable agent infrastructureEnjoy working in fast-paced environments with high ownership and autonomyAre proactive, detail-oriented, and take pride in building high-quality systemsThe ProcessWe aim to hire with intention, respect your time, and offer feedback along the way.Initial conversation (20 minutes) We'll explore your motivations, share what we're building, and answer your questions.In-depth interview (45 minutes) We'll go deeper into your craft and experience.

Companies spend over $1T a year on customer-facing teams and $150B on the tools meant to support them, yet every team still pieces context together across a dozen disconnected systems. We're rebuilding this from the foundation, and AI makes now the only moment it's possible.The most interesting place to apply AI is where the work actually happens. Customer operations is one of the largest, most under-built surfaces in software. Every company runs on it, every team feels the pain, and the tools haven't been seriously reimagined in fifteen years. We think the next generation of category-defining B2B companies will be built here.One platform, every customer-facing team.
Sales, success, support, and ops all serve the same customer relationship, but each one buys a different tool to do it. Owning the foundation means the surface area grows with the company, from a single team to the entire revenue org to the whole business. That's the market, and the mission: better service at internet scale.Lapel works in person in San Francisco, five days a week, at our office on Market Street.
