Founding Engineer – RetainSure (Bengaluru)

Full-stack • Python/FastAPI • React • Postgres • AWS • Early-stage.

RetainSure is an AI Customer Success Manager that eliminates the need for CSMs for low-touch accounts and reduces headcount by 80% for high-touch teams. 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.

• Build high-quality user-facing experiences in React.
• 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.

What We’re Looking For

Must-haves

• 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.
• Opportunity to architect systems that will scale globally across enterprise customers.
