Their technology autonomously handles over 75% of client support interactions across email, SMS, WhatsApp, and voice. We are seeking a heavy-hitting Senior to Principal level Software Engineer (7–12 years of experience) to join a lean "rockstar" engineering team. You will help scale the engineering organization from 6 to 12+ members while maintaining a rapid shipping velocity. This is a backend-leaning, full-stack role for an elite Individual Contributor who wants to build at the frontier of AI. What You’ll Do * Architect & Ship: Lead the development of major features for omnichannel AI agents, making critical decisions on infrastructure and system design. * Build with AI: Integrate AI coding tools (Cursor, Claude Code) into your daily workflow to accelerate development. * Collaborate: Work directly with the CTO and founders to shape technical strategy and product direction in fast-paced weekly cycles. * Scale Systems: Design and deploy scalable, high-impact systems on AWS that support 6–7x year-over-year revenue growth. * Operate Full-Stack: Move fluidly across the stack as needed—shifting priorities weekly based on business impact rather than staying in a technical silo. Who You Are * The Veteran IC: 7–12 years of production experience at top-tier Big Tech firms or recognizable high-growth startups. You are a builder, not a manager. * Python Expert: Deep production experience with Python as a primary backend language. Familiarity with TypeScript and React is a strong plus. * AI-Native Developer: You are highly proficient with modern AI coding tools and believe in the "10x engineer" potential of agentic workflows. * Product-Minded: You understand the business context of your code and care about the "why" behind the product. * Education & Background: Strong academic background (Top CS programs) or previous experience as a founder/CTO is highly preferred. Why Join? * Work with a team of ex-Meta, Google, and Microsoft engineers. * Massive equity upside in a company that has proven product-market fit and explosive revenue growth. * High autonomy in a "no-ego" environment where the best ideas win.
