Founding Engineer
Help us build the operating system that hotels actually run on. You will own real surface area, ship every day, and shape the product for years to come.
You will work directly with the founders out of our Mission office in San Francisco. We move quickly, write clear code, and treat reliability and security as first-class features because hotels around the world run their operations on what we ship.
What you will do
- Design, build, and operate end-to-end product surfaces across the Harlow platform: agent runtime, integrations, dashboards, and APIs.
- Own integrations with property management systems, channel managers, messaging platforms, and telephony providers.
- Build the evaluation and observability tooling that keeps the agent reliable, fast, and trustworthy in production.
- Take features from a customer call to a shipped, monitored product in days, not quarters.
- Set the engineering bar for the team that comes after you: code review, testing, security review, and incident response.
What we are looking for
- Five or more years writing and operating production software, with deep experience in TypeScript or Python.
- Comfort across the stack: APIs, data, queues, infra, and a UI when needed.
- Strong sense for product. You can read a customer conversation and design the right thing.
- Calm under pressure. You enjoy debugging hard problems and care about the experience of the team on call after you.
Bonus
- Built or operated agentic systems on top of LLM APIs in production.
- Worked at a seed-stage company where you owned a meaningful slice of the product.
- Background in hospitality, communications, or vertical SaaS.
