Yoptima Media Solutions - Principal Engineer - Generative AI Platform

Were 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 :

- 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 :

- 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.

- Architect and build scalable microservices and APIs that are robust, maintainable, and performant.

- Drive adoption of engineering best practices, including clean architecture, SOLID principles, and design patterns.

- Collaborate closely with cross-functional teams, including Product, DevOps, QA, and UX to deliver quality solutions.

- Mentor and guide junior and mid-level engineers through code reviews, design sessions, and pair programming.

- Proactively identify tech debt and propose scalable, long-term solutions.

- Ensure strong engineering processes through Agile practices, CI/CD pipelines, and DevOps automation.

- Stay updated with emerging trends in technology and evaluate their adoption as needed.

- Contribute to hiring and talent development efforts within the engineering team.
