Why This Role Matters
We’re looking for a Principal Engineer to lead the architecture and execution of our GenAI-powered, self-serve marketing platforms. You will work directly with the CEO to shape, build, and scale products that change how marketers interact with data and AI. This is intrapreneurship in action — not a sandbox innovation lab, but a real-world product with traction, velocity, and high stakes.
What You'll Do
- Co-own product architecture and direction alongside the CEO.
- Build GenAI-native, full-stack platforms from MVP to scale — powered by LLMs, agents, and predictive AI.
- Own the full stack: React (frontend), Node.js/Python (backend), GCP (infra), BigQuery (data), and vector databases (AI).
- Lead a lean, high-caliber team with a hands-on, unblock-and-coach mindset.
- Drive rapid iteration with rigor, balancing short-term delivery with long-term resilience.
- Ensure scalability, observability, and fault tolerance in multi-tenant, cloud-native environments.
- Bridge business and tech — aligning execution with evolving user and market insights.
What You Bring
- 8–12 years of experience building and scaling full-stack, data-heavy or AI-driven products.
- Fluency in React, Node.js, and Google Cloud (Functions, BigQuery, Cloud SQL, Airflow, etc.).
- Hands-on experience with GenAI tools (LangChain, OpenAI APIs, LlamaIndex) is a bonus.
- Track record of shipping products from ambiguity to impact.
- Strong product mindset — your goal is user value, not just elegant code.
- Architectural leadership with ownership of engineering rigor and scaling best practices.
- Startup or founder DNA — you’ve built things from scratch and know how to move fast without breaking things.
Who You Are
- A former founder, senior IC, or tech lead who’s done zero-to-one and 1-to-n scaling.
- Hungry for ownership and velocity — frustrated by bureaucracy or stagnation.
- You code because you care about solving real problems for real users.
- You’re pragmatic, hands-on, and grounded in first principles.
- You understand that great software isn't just shipped — it's hardened, maintained, and evolves with minimal manual effort.
- You’re open to evolving into a founding engineer role with influence over the tech vision and culture.
What You Get
- Equity in a high-growth product-led startup.
- A chance to build global products out of India with full-stack and GenAI innovation.
- Access to high-context decision-making and direct collaboration with the CEO.
- A tight, ego-free team and a culture that values clarity, ownership, learning, and candor.
