We integrate deeply across product, CRM, support, billing, and external signals to build a unified intelligence layer, and deploy specialized AI agents that behave like a human CSM across backstage, in-meeting, and in-product workflows.
We’re now hiring a Founding Engineer to join our core team and help build the next $100M+ AI infra layer for Customer Success.

- Design, optimize, and maintain database schemas and high-throughput workflows.
- Work directly with the founders to define product, ship fast, and iterate with customers.
- Own modules end-to-end, from concept → architecture → implementation → monitoring.
- Set engineering standards, improve dev velocity, and lay the foundation for the engineering culture.

- 2+ years of experience as a Full-Stack Engineer in high-velocity environments.
- Strong backend fundamentals: Python, FastAPI, SQL/Postgres, distributed systems basics.
- Solid frontend engineering with React.
- Strong grasp of DSA, algorithms, and database internals.
- Deep comfort with AWS (EC2, S3, Lambda, RDS, VPC, IAM, etc.).
- Bias toward action, ownership, and solving real customer problems.
- Ability to move fast without compromising code quality.
Cherry on Top
- Ambition to start your own company in the future: we love founders-in-the-making.
- Experience building large-scale SaaS systems, data platforms, or AI-driven workflows.
- Worked in early-stage startups or shipped 0→1 products before.
What You’ll Get
- Founding-level ESOPs with outsized ownership.
- Work with founders experienced in building/scaling SaaS (Rubrik, Mailmodo, ClearTax).
- High trust, zero bureaucracy, rapid execution environment.
