This is not your average SaaS job. You’ll be building real-world technology that helps keep construction and industrial sites safe and secure - think intelligent monitoring systems, intrusion detection, and field asset tracking.

After years of steady growth, a major investment has just landed. The engineering team is now breaking apart a legacy monolith to build focused, product-led teams from the ground up. You’ll play a pivotal role in building a brand-new customer-facing platform, with real ownership across infrastructure and feature development.

What you’ll be working on

  • Greenfield development: New platform to replace an 8-year-old legacy system (currently in maintenance mode).
  • Customer-facing features: First up? A smart intrusion detection system - smart scheduling, site control, real-time feedback loops.
  • DevOps meets Engineering: You’ll bridge software with infrastructure - managing CI/CD, cloud infra (AWS), security, observability.
  • Shape the stack: Most of the new work is in TypeScript and AWS - but you’ll help choose the right tools for the job.
  • Build it right: Define how software is shipped, tested, monitored, and evolved - from local dev through to production.

You might be the one if you…

  • Are a senior backend/software engineer with TypeScript/Node experience (or similar).
  • Have solid cloud infrastructure chops - ideally AWS - and know your way around CI/CD and infra-as-code.
  • Thrive in ambiguous, high-growth environments - startup or scale-up experience preferred.
  • Love to solve problems that touch the real world.
  • Are comfortable being the "go-to" on your team and enjoy figuring things out from scratch.

Bonus points if you’ve dabbled in:

  • DevOps or Site Reliability Engineering (SRE)
  • Building out monitoring and alerting systems
  • Supporting product-focused teams while managing infrastructure

The culture

You’ll be joining a tight-knit, high-trust team where everyone’s close to the work.

It’s hands-on, high-impact, and collaborative.

Interested?

You don’t need a perfect resume. You just need to show us you’re hungry to build and curious about the intersection of hardware, software, and people.
