Be our first marketing hire and build demand for CosX in the US and Europe - the person who makes a CTO in London, San Francisco or Toronto discover CosX, trust CosX, and reach out to us first.
Own the top of our enterprise sales funnel — research high-value accounts across India and international markets, run personalised outreach, and set up qualified conversations that the founders close.

Own the analytics behind CosX's marketing motion - from content performance to pipeline attribution - and turn data into clear recommendations the team can act on.
Design the product surfaces that operators actually use - dashboards, agent control planes, and the small interactions that make AI feel trustworthy day to day.
Build the high-performance services and runtimes behind production AI agents - low-latency inference paths, data pipelines, and the platform glue that everything sits on.
Work alongside senior AI engineers on real production agents - from evals and prompt engineering through model integration and the messy bits of shipping AI into live workflows.
