Founding Tech Lead (GrowthBricks)

Founding Tech Lead (GrowthBricks)

Are you a hands-on engineer who loves zero-to-one challenges? Do you want to build systems with real context and memory that do more than reason, use tools, and drive actual business outcomes?

About JetBrains

We create intelligent software development tools for developers and teams. More than 15 million users, over 300,000 companies, and 88 of the Fortune Global Top 100 rely on our products to solve real, complex problems. Our mission is simple: make development teams more productive and AI adoptable at scale.

GrowthBricks is a new project at JetMinds, backed by JetBrains, designed to give GTM teams and AI agents a shared business brain. Business context usually gets fragmented across CRMs, documents, dashboards, and people's heads. GrowthBricks brings that context together so agents and people can make decisions and execute effectively across the sales, marketing, and product stack.

What you’ll do

As our Founding Tech Lead, you will own the technical architecture and core systems from the ground up. Working directly with the product founder, you'll tackle the core challenge of turning messy, shifting business data into reliable memory and agent actions, then measuring whether those actions deliver real results. You will shape the product primitives, write much of the early code, and decide how our technical approach evolves as we learn what works.

Day to day, you will:

•Design the core architecture across business context, agents, memory, tools, and feedback loops.

•Build agentic workflows that reason over company context and act across CRM, sales, marketing, and product systems.

•Create context extractors to process sales calls, emails, internal docs, CRM states, and campaign data.

•Work closely with prompting, context management, memory, tool choice, and orchestration.

•Connect GrowthBricks directly to the existing GTM stack rather than rebuilding existing tools.

•Decide where to leverage MCP, APIs, or open-source frameworks, and where custom solutions are worth building.

•Prototype quickly, discard weak ideas, and turn effective ones into production primitives.

What you’ll bring

•Comfort working in zero-to-one environments with high technical autonomy.

•A practical mindset that values clear, simple solutions over unnecessary complexity.

•Confidence making key architectural decisions when requirements are still evolving.

•A focus on end-user impact and willingness to iterate based on real feedback.

What you’ll need

•Hands-on experience building, evaluating, and refining LLM applications, agents, or agentic workflows used by real people.

•Demonstrated experience designing backend systems, data models, APIs, and integrations.

•A working knowledge of context management, memory patterns, prompting strategies, and tool orchestration. …
