Build the platform a $50 billion industry runs on!

Belfry is changing how the security guard services industry runs. We give back-office teams and field officers one modern platform to do their best work, and we are early enough that the engineers who join now will decide what it becomes.

This is a seat for an engineer who wants the full early-stage experience: shape the tech stack, own real pieces of the product, learn directly from industry experts and investors, help build the team, and share in the upside through meaningful equity.

What you'll own

You will have real responsibility from day one. A few of the problems waiting for you:

  • AI agents for real customers. Build agents that solve actual customer problems, not demos.

  • The architecture. Design the foundation that lets Belfry scale as our user base grows.

  • How we build. Evolve our software development lifecycle to take full advantage of agentic tools.

  • Reliability you can trust. Deploy and scale systems with secure, available, performant best practices, and improve monitoring and telemetry so we always know how the product is behaving.

  • Standards and team. Set the technical standards across the full lifecycle, and improve the practices that make your fellow engineers faster.

Built for Engineers who..

  • Have 6+ years as a software engineer and have owned complex backend or infrastructure projects before.

  • Want a high degree of responsibility and are excited to shape a company, not just a codebase.

  • Explain technical decisions and product ideas clearly, and grow by helping the people around them grow.

  • Pick the right tool for the job, and are actively exploring how AI coding tools change the way software gets built.

  • Have familiarity with React, Python, TypeScript or React Native. This is a plus, not a requirement.

Why join Belfry?

  • Significant equity in a high-growth startup with a clear path to significant outcomes.

  • Real ownership. Shape the tech stack, own the product, and help build the team.

  • A team with a fantastic track record, plus direct access to industry experts and investors.

  • Fully covered healthcare, dental and vision.

  • Unlimited PTO and 11 paid holidays, and we actively encourage you to use them.

Sound like the kind of problem you want to own? We would look forward to you applying!
