AI Technical Lead

About us

At the company, we don’t just follow technology trends – we redefine what’s possible with AI. Every project we take on is a chance to build meaningful digital experiences powered by smart, scalable AI solutions. Whether we’re automating complex processes, enhancing user journeys, or enabling data-driven decisions — we’re here to make innovation real.

Excited about solving tough challenges for startups, scale-ups, and enterprises around the world? Curious about how AI can drive real business value, not just hype? That’s the space we operate in. You won’t have to choose between commercial impact and meaningful tech — our portfolio includes Open Source projects, nonprofit work, and deep partnerships with forward-thinking companies.

Apart from that, you will find yourself in an authentic and open company culture. Our non-hierarchical structure means minimal management and transparent communication with everyone (including the CEO).

Now, let’s see what else makes joining our Crew so exciting! ⛵

• Strong background in TypeScript, Node.js, React, and Next.js.

• Proven experience leading AI projects end to end, from scoping and estimation to production rollout.

• Solid understanding of RAG architecture, vector databases, and LLM integrations.

• Experience with multi-agent frameworks, workflow orchestration, validation, and observability.

• Familiarity with textbots, voicebots, image/video generation, avatars, and automation systems.

• Strong knowledge of AI models and providers, including cost optimisation and API management.

Your responsibilities will include

• Designing, leading, and implementing production-ready, AI-driven solutions, including multi-agent architectures and RAG-based systems.

• Conducting technical discovery and estimation sessions with clients — translating requirements into architecture and implementation plans.

• Advising product and tech teams on AI strategy, tool selection, and long-term scalability.

• Ensuring technical excellence, code quality, and mentoring team members.

• Supporting the adoption of AI-UX and agentic design principles across products.

• Monitoring the performance and resilience of deployed systems to maintain quality over time.

What success looks like after 6 months

• Led 1-2 agentic projects end to end, from discovery through production launch.

• Established strong architecture standards for RAG and agentic systems.

• Mentored 3-5 engineers and helped raise the team’s technical bar.

• Improved production systems by reducing hallucinations, latency, and infrastructure costs.
