What we're building

We're a small, sharp team — founders, IIT/IIM folks, and industry veterans who've done this before. No bureaucracy, no layers, no meaningless standups. You'll work directly with the founding team on problems that are genuinely hard.

What we need from you

You've spent 4–8 years in AI/ML, and at least 2 of those years building real multi-agent systems — not demos, not POCs that never shipped. You've worked on at least 2 multi-agent platforms (AutoGen, CrewAI, LangGraph, custom orchestration — whatever, as long as agents were actually coordinating and not just chained prompts).

You think about:

• Agent memory, state, and context management
• Inter-agent communication and task delegation
• Failure handling, retries, and graceful degradation
• Tool use, MCP, and external system integration
• Evaluation and observability of agent behaviour

You're probably a fit if:

• You've debugged an agent loop at 11pm and found it weirdly satisfying
• You have opinions about when not to use an agent
• You care about systems that work in production, not just on your laptop

You're not a fit if:

• Your portfolio is mostly RAG pipelines and chatbots
• Your multi-agent experience is only a tutorial project or a hackathon demo

What we offer

• Best-in-class pay — we benchmark against top-tier tech and don't lowball on talent
• Direct access to founders and a senior team of IIT/IIM grads and industry veterans
• Flexible work — async-friendly, output-driven, no performative office hours
• Real technical ownership — you'll make architecture decisions, not just implement them
• Small team means your work ships fast and actually matters

Why Sentiaflow, honestly We're early. That means some things aren't figured out yet. But it also means the person we hire here will have shaped how this company thinks about agentic systems from day one. If you want to inherit a codebase and execute tickets, we're not the right place. If you want to build something from scratch with people who take the craft seriously, let's talk.

How we hire A quick intro call to get to know each other. If there's a fit, show us something you've built — a demo, a walkthrough, a system you're proud of. That's the interview. No better signal than watching someone talk about their own work.
