[Hiring] Founding Tech Lead @JetBrains

Role Description

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.

Qualifications

• 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.

Requirements

• 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.
• A practical understanding of modern GTM stacks (such as CRMs, enrichment tools, or marketing automation) or sales/marketing workflows is a plus.

Benefits

• Strong base salary – We offer competitive pay that reflects your skills and experience.
• Flexible work schedule – Enjoy the freedom to work from home or from the office.
• Extra time off – More days to relax, recharge, and do the things you love.
• Learning and development opportunities – Access to conferences, courses, and language classes.
• Relocation support – Assistance to help make your move as smooth and stress-free as possible.
• Free meals and snacks – Lunch and refreshments provided to keep you fueled.
• Health and wellness – On-site gyms or sports club stipends.
• Internal events – Company-wide celebrations and team gatherings.
