Descripción del empleo

Muck Rack is trusted by thousands of organizations around the world to understand how their brands show up across news, social media and AI-generated answers.

Our AI-powered platform connects the entire PR workflow in one place, helping communications teams manage media relationships, understand the conversations shaping their brands, take action and measure their impact. Combined with analyst-led Media Intelligence and advisory services, Muck Rack turns signals into insights and insights into action.

Founder-controlled and growing profitably and sustainably, we have the freedom to build forward-thinking products, put our customers first, and offer an inclusive culture that welcomes diverse perspectives.

• Ship the full experience. Build in-product chat, streaming responses, permission-aware APIs, and our external MCP server
• Make quality measurable. Build evals, catch regressions, and use production feedback to improve quality, latency, and cost
