About the role

Founding tech lead role to design and build GrowthBricks from zero, turning fragmented business context into reliable memory and agent actions, reporting directly to the product founder.

Responsibilities

  • 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.

Qualifications

  • 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.
  • Working knowledge of context management, memory patterns, prompting strategies, and tool orchestration.
  • Practical understanding of modern GTM stacks (such as CRMs, enrichment tools, or marketing automation) or sales/marketing workflows is a plus.
