About Blacklight AI

Remote-first. Open to candidates anywhere in the US.

Blacklight AI is an agentic AI platform disrupting how the world approaches cybersecurity. We are not improving the old model. We are replacing it: autonomous monitoring, detection, response, and threat hunting, powered by AI that moves faster than any attacker and never stops working.

We operate across North America, the UK, the UAE, Australia, and Asia, serving some of the most security-conscious organisations on the planet across Financial Services, Government, Healthcare, Energy, and beyond. The cybersecurity industry has been running on the same broken playbook for decades. Blacklight AI was founded to change that.

Recognised by Google. Recognised by Wavestone. Recognised by Accenture Fintech Innovation.

About the Role

We are looking for a Full Stack Developer to help extend and scale our globally-distributed cybersecurity SaaS platform. You will write clean, elegant code and take features from build through to deploy and into production monitoring.

Responsibilities

  • Write clean, maintainable code with strong refactoring discipline, including when working with AI-assisted IDEs
  • Build and maintain backend services using Express.js and Bun
  • Operate the application in production: provisioning, deployment, and monitoring
  • Build and maintain responsive, high-quality frontend interfaces using Vue
  • Take end-to-end ownership of features: from first commit to production alert

Who You Are

  • Hands-on exposure to incident response, network traffic investigation, or offensive security
  • Prior experience designing and shipping security-focused software
  • Energised by fast-paced cycles and eager to prototype novel concepts
  • You care how software performs in the field, not just in the test suite

Skills and Qualifications

  • 5+ years of full-stack development experience (mid to senior)
  • Strong JavaScript experience across Bun, Express.js, and Vue
  • SaaS experience: shipped and operated a production web application
  • Familiarity with Linux
  • Cloud experience including:
    • Provisioning: VMs, networking, storage, managed services
  • Monitoring and observability: metrics, logs, alerting
  • Security-conscious configuration and operational hygiene
  • Familiar with Martin Fowler's refactoring concepts and able to apply them in practice

Nice to Have

  • Exposure to threat intelligence pipelines, SIEM integrations, or event stream processing
  • Experience with WebSockets or real-time data pipelines
