About Calvis
* Calvis is making the trillion-dollar physical security industry AI-native. Today the industry is outdated, fragmented, and run on pen and paper. With Calvis, Humans + AI work together to secure the world.
* Our marketplace connects businesses with vetted security guards who work every shift using our AI copilot. It briefs them, takes their reports, and helps them do a great job. Meanwhile, every shift generates data that continuously makes our AI better.
* We enhance guards with robots and AI video monitoring, making Calvis the only all-in-one security offering on the market.
* Clients across the country, from critical infrastructure to manufacturing facilities, trust Calvis to help keep them safe.

Why join?
* Very small team, in person, in office. Work directly with the CEO and CTO.
* The business has grown fast over the last year, and our growth rate is only accelerating.
* Complete ownership and autonomy. You own what you work on, end to end, and you decide how to build it. We have plans, but autonomy is the point: it means looking around corners and building for what's coming before it's on our roadmap.
* Your work ships fast and lands in the real world with real guards.
* Everything is still early. The systems you build here become the foundation an entire industry runs on.

The role
* Build agents that understand the physical world: directing guards, robots, and sensors working together on a live site.
* Own products end-to-end. You get to understand the guards and customers who use what you build, figure out what they need, and ship.
* Work full stack across every surface we have: backend server, web dashboard, native iOS and Android apps, and the agent infrastructure underneath all of it.
* Take what’s working and scale it. Our products have real usage and real revenue but are still early. You’ll harden them, iterate against live data, and turn v1s into systems thousands of sites depend on.### Who you are
* Worked at a high-growth startup before. You thrive in chaos, change, and uncertainty.
* You work hard, and you’re wired in. The business, the problems, and the thing you’re building stay on your mind because you actually care.
* You build with AI every day and treat staying at the frontier as part of the job. You’re constantly learning from new models, tactics, and workflows, and folding them into how you work.
* Product mindset. You don’t just ship code, you dig into what users are actually struggling with and care about the experience you build.
