Fibr AI · HSR Layout, Bengaluru (in-office) · Full-time · 5–9 years

About Fibr
Websites were built for humans clicking around, and that’s changing fast. Visitors now arrive from ChatGPT and Claude, and AI agents increasingly browse, compare and act on people’s behalf. Fibr is building the experience layer that adapts every website to whoever is visiting, human or agent.
We’re Accel-backed and cash-flow positive. Our customers include 20 of the Fortune 500 and 3 of the top 5 global banks. We recently launched Agent Experience Optimization (AXO), which extends 1:1 personalization to AI agents.

What you’ll do
Lead a small engineering pod: set direction, review designs and code, and help 1–2 engineers grow, while staying hands-on as a builder yourself.
Own multi-agent systems end to end: ad and LLM intent to personalized pages, agentic site audits that launch experiments, and real-time AI-agent detection on live sites.
Make the architecture calls on LLM orchestration, workflow engines, evals and observability.
Scope problems with customers and product, prototype fast, and take what works from POC to production.
Set the engineering bar for quality, reliability and speed on the AI platform.

What we’re looking for
5–9 years building backend or product systems, mainly in Python (Django or FastAPI) with Postgres.
1–2 years managing people: you’ve directly led 1–2 engineers, including their reviews, mentoring and delivery.
At least 1.5–2 years shipping LLM or agent features to real users in production.
Hands-on with agent frameworks, RAG, tool-calling, structured outputs and eval-driven iteration.
Strong product judgment: you turn ambiguous problems into shipped software and use production data to decide what to build next.
Product-company or startup background.

Nice to have
Personalization, experimentation, CRO or martech experience.
Temporal or similar orchestration, LLM gateways or observability, Kubernetes or GCP.
Experience working directly with enterprise customers.

Why Fibr
Lead the engineering behind a new category: agent readiness.
High ownership in a small team, working directly with the CEO.
What you and your team ship goes live for global brands and banks.
