We're looking for a Founding AI Engineer to lead a new strategic direction where you will design and build AI architecture from scratch, integrate LLMs into a scalable no-code platform, and become the technical core of a product with a global audience of 70+ million users.

About the Company:

Our client is an international technology company with a 15-year track record, founded in 2011 in Canada. The core product is a no-code mobile app builder with a strong focus on Android, which enabled the company to build a large organic user base.

Since 2019, the project has been developed by a CIS-based team:

  • iOS support has been added
  • The engine has been fully rewritten
  • The interface has been redesigned
  • The architecture has been rebuilt for cross-platform development

Scale:

  • 70+ million monthly users
  • 20+ million downloads
  • 80,000+ applications published on Google Play
  • Strong presence in Asia, Africa, and the MENA region

The company is now launching a new strategic direction - an AI-powered builder that generates mobile applications from text prompts.

The product is currently in closed beta:

  • Initial insights have been collected
  • Market demand has been validated
  • Development priorities have been defined

At this stage, architectural limitations of the legacy system have been identified during LLM integration, along with the need to strengthen internal AI expertise to scale the AI core.

To address these challenges, the company is hiring a technical leader with hands-on experience in building generative AI systems.

Responsibilities:

  • Design and develop AI agents (multi-step workflows, prompt engineering, tool and state management)
  • Orchestrate and evaluate multiple LLMs; build evaluation pipelines (evals) and run A/B testing
  • Implement secure code execution in isolated environments
  • Develop full-stack solutions in TypeScript
  • Implement real-time functionality (WebSockets, streaming)
  • Design finite-state machines for complex workflows
  • Implement monitoring systems (tracing, cost tracking, latency metrics)
  • Diagnose non-deterministic errors (model behavior, context handling, prompt issues)

Tech Stack:

  • Infrastructure: Cloudflare Workers, Durable Objects, D1, Containers (serverless-first approach)
  • AI Core: Custom Orchestrator (Cloudflare Agents SDK), OpenAI SDK, Sandbox SDK
  • Frontend: React 19, TypeScript, Vite, TailwindCSS
  • Backend: Hono, Drizzle ORM

Required Experience:

  • Experience building generator platforms / builders / low-code or AI development tools
  • Hands-on experience architecting complex LLM- or agent-based systems from foundation to first users
  • Experience building AI agents
  • Experience working with model APIs (OpenAI, Anthropic, open-source models)
  • Strong prompt engineering expertise
  • Product mindset (rapid prototyping, iteration)
  • Strong TypeScript skills (full-stack development)

Location & Conditions:

  • Compensation: Up to $10,000 gross (negotiable after interviews) + equity
  • Contract Type: B2B
  • Location: Remote (preferably Eastern Europe / CIS)
  • Timezone: CET
