Threat Investigation Engineer (Backend/Platform)

Remote | 1-year Contract

About the Role

We are seeking a Threat Investigation Engineer to build, improve, and support AI-powered systems used in high-stakes safety and threat investigations.

This is a hands-on software engineering role combining backend development, production troubleshooting, and platform reliability. You'll work closely with investigators and engineering teams to develop practical solutions, improve existing workflows, and ensure critical investigation systems operate reliably.

The ideal candidate is a strong Python engineer with experience building and maintaining production applications, troubleshooting complex systems, and integrating AI-powered capabilities. You should be comfortable navigating ambiguous technical challenges, working directly with end users, and taking ownership of solutions from initial problem definition through deployment and ongoing support.

This position includes participation in a rotating on-call schedule, including weekend and holiday coverage, to support critical investigation workflows.

What You'll Do

• Design, develop, test, and maintain backend services and AI-assisted applications that support threat investigation workflows.
• Partner directly with investigators to understand operational challenges, identify opportunities for improvement, and translate requirements into practical engineering solutions.
• Build and integrate AI-powered features, APIs, and services that improve the efficiency, accuracy, and reliability of investigation processes.
• Troubleshoot and resolve production issues, including failed workflows, processing delays, data inconsistencies, and system errors.
• Participate in rotating on-call coverage, including weekends and holidays, to diagnose issues, implement fixes, and escalate when necessary.
• Improve system reliability and observability through monitoring, logging, automated testing, documentation, and operational tooling.
• Investigate complex technical issues across backend services, data pipelines, and AI-assisted workflows, identifying root causes and implementing sustainable solutions.
• Collaborate with engineering and platform teams to deploy improvements, maintain system stability, and support evolving operational needs.
