About the Role:

We are looking for an AI Enablement Specialist — a highly proactive, cross-functional professional who will help us rethink how digital products are built, delivered, and scaled using AI.

This is not a traditional engineering or design role. Instead, we’re looking for someone who understands product development holistically — spanning business, design, and engineering — and can identify, test, and implement  AI-driven approaches that significantly improve speed, quality, and innovation.

You will play a key role in shaping how we adopt AI across workflows, from early prototyping to delivery and even sales enablement.
 

Key Responsibilities:

— Drive AI adoption and modernization across product development processes.

— Identify, test, and implement AI-powered tools and workflows to accelerate delivery.

— Actively participate in brainstorming, product discussions, and strategic decisions.

— Propose new approaches and ideas — including those the team hasn’t yet even considered.

— Facilitate strong cross-team communication between business, design, and engineering.

— Prototype solutions using modern AI tools instead of traditional workflows where applicable.

— Continuously explore and evaluate emerging AI tools and methodologies.

— Build and showcase real use cases demonstrating efficiency gains and improvements.

— Support client-facing activities and sales, helping articulate AI-driven value propositions.

— Educate and guide teams on how to effectively leverage AI in their daily work.
 

What We’re Looking For:
— Proven examples of process optimization or innovation using AI.
— Strong understanding of digital product development (across design, engineering, and business).
— Experience and deep interest in AI-enabled workflows and tools.
— Experience in pre-sales, consulting, or client interaction.
— A self-starter mindset — someone who brings ideas, not just executes tasks.
— Excellent communication and facilitation skills.
— Curiosity and drive to continuously explore, experiment, and improve.
— Ability to translate complex ideas into clear, actionable insights.
— Understanding of how businesses operate and how technology drives value.
— Experience with rapid prototyping and modern tools (LLMs, AI copilots, no-code/low-code platforms, etc.).
 

What Success Looks Like:
— Faster product development cycles through AI-driven improvements.
— Tangible examples of efficiency gains and innovation.
— Increased adoption of AI tools across teams.
— Increased number of new clients driven by improved delivery capabilities, visible innovation, faster execution, and AI-powered value delivery.
— New, unexpected ideas that push the company forward.
 

What we offer for you to succeed:

— Warm and friendly working environment with flexible start (from 8:00 to 11:00) based on personal preferences and team meetings.

— We put a healthy work-life balance first.

— Caring for physical and mental health.

— Speaking Club and English with a teacher.

— Volunteer projects that help the state get closer to victory.
