Founding Tech Lead (GrowthBricks)

JetBrainsAmsterdamOn-siteFull-time29 Sept 2026

JetBrains is seeking a hands-on Founding Tech Lead to build GrowthBricks, a shared business brain for GTM teams and AI agents, from zero. The role involves owning the technical side of the product, including architecture, core systems, integrations, and the agent layer, with a focus on turning fragmented business context into reliable memory and agent actions. The ideal candidate has strong hands-on engineering experience with LLMs, agents, and agentic workflows, and can design backend systems and integrations.

What you'll do

Design the core architecture: business context, agents, tools, integrations, and feedback loops.
Build agentic workflows that can reason over company context and act across CRM, sales, marketing, and product systems.
Build context extractors from GTM team artifacts like sales calls, emails, internal documents, CRM state, marketing campaigns, etc.
Work on prompting, context management, memory, tool use, and orchestration.
Connect GrowthBricks to the existing GTM stack rather than rebuilding everything around it.
Decide where to use MCP, APIs, frameworks, or third-party tools and where a custom solution is worth it.
Prototype fast, discard weak ideas, and turn the useful ones into product primitives.
