Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.
The role
This company builds the realtime messaging infrastructure behind products used by millions of devices, processing billions of messages daily for global brands. Their customers are developers. Earning their trust means obsessing over every surface they touch: the analytics dashboard, the documentation, the sign-up journey, the billing UI.
This is a Staff-level, full-stack role. You'll report directly to the CTO, co-own the DevEx vision, and lead a team of five engineers responsible for every customer-facing web application. You are the target user of what your team builds; this isn't a feature factory. You'll set the technical architecture, push for rapid iteration, and ensure your team acts as principal stakeholders, not just implementers.
The work
This is a rare leadership role at a company building critical infrastructure, often hard to find through traditional channels. Apply through Dex to cut through the noise: we'll match you to this role and others like it, brief you thoroughly before any interviews, and help you skip the cold-apply process entirely.
