• Ship customer facing features across the full stack, with a focus on smooth user experiences. • You’ll design and build intelligence features from zero-to-one from loosely defined specs, collaborating closely with your product, design, and engineering teammates. • You should be comfortable making calls, evaluating outcomes, and iterating on your work to make the best experience for customers. • Sweat the front-end craft. • You care about responsiveness, streaming/loading states, accessibility, and the small details that make an assistive feature feel reliable rather than gimmicky. • Stay close to customers. • Join customer calls when more context is needed to design the right solution, participate in a support escalation rotation, and watch session recordings on the features you own. • Bring that signal back into the work. • Own outcomes, not just output. • Before a project starts, you and a PM agree on a specific outcome metric the work is trying to move. • You instrument it, and after it ships you're watching the dashboard and talking to customers to ensure its impact. • Co-author the solution. • PMs own strategy and sequencing; you bring the judgment and craft for how solutions actually get built. You'll often shape the product thinking too. • The best work happens when engineers, designers, and PMs support each other. • Own production readiness from the start. • Automation, reliability, monitoring, alerting, and logging are all part of how you ship. • The work continues after merge. • Use AI tools every day as part of your craft. • We expect fluency with Cursor, Claude Code, or similar. • If you saw a way to make the team's AI workflow better tomorrow, you'd say so. • Help us hire. • From time to time, partner with our Talent team to interview future teammates. This is one of the highest-leverage things any engineer here does.

• Building a next-gen stack for resilient, decentralized search • Empowering anyone to create a self-organizing search engine for various data types • Innovating in peer-to-peer architecture with no centralized index

• Maintain and manage CT's Azure cloud infrastructure such as App Services, Front Door, SQL Server, and Web Application Firewall • Manage client security questionnaires, write and maintain security policy documentation, and run disaster recovery testing • Communicate directly with clients during new software installations and troubleshoot connectivity or configuration issues as they arise • Generating 30%+ of your code output using AI-assisted development tools—and using them thoughtfully to accelerate delivery without sacrificing quality • Shepherd end-of-life cycle products while keeping existing systems running smoothly
