Stealth Startup | Full-time | Bangalore (on-site/hybrid)
We're an early-stage, stealth-mode startup building AI agents for high-stakes enterprise workflows. We're a small team of experienced builders backed by strong conviction that the next generation of enterprise software won't just assist people — it will do the work, with humans supervising where it matters.
We can't say much publicly yet. What we can say: we're solving hard problems at the intersection of AI agents, browser automation, and enterprise-grade trust — in domains where correctness, auditability, and security aren't nice-to-haves, they're the product.
What you'll do
- Own large pieces of a full-stack platform end to end — from architecture and design docs through implementation, testing, and production operations
- Build agentic systems: LLM-driven execution loops, tool use, human-in-the-loop interaction models, and evaluation harnesses that keep agents honest
- Work across a modern stack: TypeScript/Node.js services, React frontends, browser extensions, real-time systems (WebSockets), and containerized deployments
- Ship into environments where security and compliance matter deeply — RBAC, audit trails, single-tenant deployments, SOC 2/HIPAA-grade engineering discipline
- Shape engineering culture, standards, and architecture as one of the earliest engineers on the team
What we're looking for
- 5+ years (Senior) / 8+ years (Staff) building and operating production software, with clear ownership of systems — not just features
- Strong fundamentals in distributed systems, API design, and data modeling; you can reason about failure modes, not just happy paths
- Depth in TypeScript/Node.js and React, or the ability to get dangerous in them fast
- Genuine curiosity about LLMs and agentic systems — hands-on experience building with them is a big plus, but strong engineering judgment matters more than prompt tricks
- Comfort with ambiguity: small team, fast iteration, direct access to customers and founders, no ticket factory
- Bonus: experience with browser extensions, workflow automation, evals/LLM testing, or regulated industries (healthcare, fintech)
Why join now
- Ground-floor equity and genuine ownership at a company still small enough that your decisions define the product
- Work directly with founders on problems that are technically deep and commercially real — we build for demanding enterprise customers from day one
- A team that values rigor: design docs, code review, and evals over vibes
If this sounds like you, we'd love to talk — even if you're not sure you tick every box. Reach out or apply with a note about the most interesting system you've built.
