• Value the quality of your code.
• Are able to solve the required technical tasks and communicate throughout the process (for example, asking clarifying questions promptly).

At Renaissance AI, we help organisations turn AI from “something people have access to” into something they confidently use every day. Our simulation-based platform helps enterprise teams (primarily in banking and corporate sectors) build practical AI habits within Microsoft Copilot, Claude, and Gemini based on a methodology featured in Harvard Business Review.
 

What you’ll be doing:
You’ll design interactive learning modules and practical scenarios, helping corporate users apply AI in real work tasks through practice.
 

Your responsibilities:
• Designing the structure of learning modules and matching them with corporate job profiles (Compliance, Risk, Operations, etc.).
• Conducting research on practical AI use cases, user pain points, and key limitations of LLMs.
• Creating concise, no-fluff theory blocks and setting up contextual scenarios for exercises.
• Developing step-by-step logic for practical tasks, simulations, and interactive quizzes.
• Reviewing, testing, and improving content quality to ensure high accuracy.

What we’re looking for:
• Experience creating educational, product training, or instructional design content.
• Structural thinking: ability to turn scattered information into a coherent, task-oriented learning journey.
• Confident daily use of AI tools (ChatGPT, Copilot, Gemini, Claude) and understanding of their limitations.
• Clear writing style, strong attention to detail, and ability to adapt tone for corporate clients.
• Experience in or understanding of corporate workflows (Finance, Banking, Legal, Compliance) is a major plus.

• Result-Oriented: Focused on delivering high-quality end products that align with business goals and reach the “Done” state
• A Strong Communicator: Able to articulate complex technical concepts clearly to both technical and non-technical stakeholders
• Flexible: Ready to quickly adjust to changing requirements, new technology stacks, or shifting project priorities
• Value-Driven: A contributor who looks beyond “just coding” to propose architectural improvements and process optimizations
• A Collaborative Team Player: Committed to knowledge sharing, active participation in code reviews, and supporting colleagues
   

What You Need For This Position

• 3+ years of experience in embedded software development (C/C++)
• Hands-on experience with Embedded Linux (Yocto/Buildroot) or RTOS (FreeRTOS or similar)
• Hands-on experience with hardware peripherals (UART, SPI, I2C) and memory management
• Experience with CMake, Python/Bash scripting, and Git
• Ability to create maintainable technical specifications and code documentation (Doxygen, Wiki, Markdown)
• English Proficiency: Upper-Intermediate (B2). Ability to conduct technical discussions, participate in meetings, and write professional documentation/emails for international clients
   

Nice to Have

• Deep understanding of Linux kernel-level debugging and architecture
• Ability to read datasheets/schematics and hands-on experience with oscilloscopes and logic analyzers
• Experience with embedded ML or Edge Computing
• Experience with wireless connectivity: BLE, WiFi, Matter, LoRaWAN
• Familiarity with ZephyrOS
   

What We Offer For Your Success

• Zero bureaucracy and no time tracking
• Flexible working hours (start your day between 8:00 and 11:00)
• 20 working days paid vacation and 15 days of sick leave
• Additional days of leave for important life events
• Professional English courses in small groups by level
• Education and anniversary bonuses
• Providing all the necessary equipment
• Full accounting support for employees
• The opportunity to rotate on projects to learn new technologies
• Opportunity for development and career growth in the areas of Tech/Team leadership, mentoring
• Office in the historical part of Kyiv (Podil) with convenient transport links and autonomous power systems, uninterrupted Internet connection, coffee, tea, and snacks
