- Work with product managers and designers to translate requirements into well-architected, scalable systems.
- Integrate with LLM-based and agentic backend systems built by the AI/ML engineering team.

- Working proficiency with modern front-end frameworks (e.g., React) to build and integrate user-facing features.
- Experience with relational/NoSQL databases, caching and cloud infrastructure.
- Ability to move fast in a zero-to-one environment while maintaining code quality and system reliability.
- Strong communication skills this is a customer-facing role, and you will be expected to clearly articulate technical concepts, decisions and trade-offs to both technical and non-technical stakeholders, including customers.

Good to Have :
