Backend Engineer

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 incredible companies, from fast-growing startups to large enterprises. We’ll share more details when we talk.

You'll build the APIs, services, and data systems that power Lapel's platform, as well as the things our products, integrations, and agents all depend on. This is a broad role with real architectural ownership, close collaboration with our product team and founders, and direct responsibility for the reliability and scalability of what we ship.d

• Build, operate, and scale the core backend systems that power the Lapel platform

• Design and develop robust APIs and services that support product features end-to-end

• Work closely with founders, product, and design to translate ideas into scalable backend solutions

• Help define and shape backend architecture, infrastructure, and tooling decisions

• Own key backend projects end-to-end, from scoping to deployment to post-launch iteration

• Design and manage database schemas, data models, and data flows across systems

• Optimize system performance, reliability, and scalability

• Implement best practices around security, authentication, and data protection

• Contribute to infrastructure and deployment pipelines

• Debug and resolve production issues, ensuring high uptime and system stability

Lapel is built end-to-end in TypeScript in a single monorepo.

• Node.js and Postgres on the backend;

• Temporal and Pulsar to power orchestration.

1. A trillion-dollar problem hiding in plain sight. 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.

2. 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.

3. 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.
