YC-backed Sei is hiring a senior DevOps engineer to build scalable infrastructure for its agentic AI platform serving global financial institutions.

Sei, an agentic AI platform specializing in financial services, is recruiting a DevOps/Platform Engineer to strengthen its infrastructure as enterprise adoption grows. The Y Combinator-backed startup (W22 batch) serves financial institutions across the US, Europe, and APAC, reporting double-digit monthly growth since launch.
The role focuses on scaling the platform's technical backbone: AWS infrastructure managed via Terraform, Kubernetes orchestration, and AI component deployment including LLMs, speech-to-text systems, and telephony integrations. Key responsibilities include cost optimization through auto-scaling, implementing open-source monitoring and security tools, and managing real-time communication infrastructure like WebRTC servers and PSTN gateways.
Technical Requirements
Candidates must demonstrate:
- 6+ years building platforms from early to growth stages
- Mastery of AWS, Kubernetes, and Terraform
- Hands-on experience with AI/ML systems and LLMs
- Proven ability to scale systems under real-world loads
The tech stack combines TypeScript for backend services, React for frontend, and Python for AI agents. Sei emphasizes practical skills over credentials, prioritizing candidates with tangible projects, open-source contributions, or technical blogging over academic pedigree.
Cultural Expectations
Sei's culture centers on:
- Continuous feedback: All team members exchange constructive criticism
- Product ownership: Engineers participate in customer discovery and support
- Action orientation: Founders code and sell daily; minimal hierarchy
- Human-centricity: Focus on end-user experience in financial workflows
The role requires working from Gurugram or Chennai offices 4 days weekly. Compensation includes ₹1.5M-₹3.5M INR annually plus equity (0.02%-0.14%), with flexibility in cash/equity allocation.
Candidate Warnings
The founders explicitly discourage applications from those seeking:
- Low-intensity work environments
- Minimal accountability structures
- Fully remote arrangements
- Superficial task completion without deep engagement
Interested engineers must email [email protected] answering six screening questions about their AI experience, ambitious projects, and work preferences. The process includes technical interviews with CTO Ramkumar Venkataraman (ex-Deutsche Bank, Amazon) and culture-fit discussions with CEO Pranay Shetty (ex-PayPal, TransferWise).
Sei's approach reflects growing demand for specialized infrastructure talent in financial AI, where reliability and scalability requirements exceed typical SaaS applications. Their public warnings about work intensity signal intentional team-building for high-growth environments.
