Full Stack Developer

Aivan is a leading Nordic design and innovation studio. We help launch, grow, and evolve progressive businesses by integrating brand, design, and communication.

We are looking for a versatile Full Stack Developer who is passionate about building high-performance web applications and is eager to expand their expertise into the world of real-time 3D environments.

This is a unique opportunity to join our Helsinki-based studio and contribute to the development of our digital team.

In this role, you will serve as the vital bridge between our web-based creative vision and technical execution. You will be responsible for architecting the "connective tissue" between modern web interfaces and real-time rendering engines. While your core strength lies in modern software engineering, this role offers a unique growth path to become a specialist in Unreal Engine 5, learning to push the boundaries of what’s possible in real-time automotive visualization.

We are looking for a forward-thinking innovator—a problem-solver who thrives on balancing aesthetic excellence with cutting-edge technical experimentation.

Key Responsibilities

System Architecture: Design, implement, and maintain scalable frontend and backend architectures that support high-fidelity interactive applications.

Web-to-Engine Integration: Develop and optimize the communication layers (e.g., WebSockets, JSON protocols, REST APIs) between WebUIs and Unreal Engine 5.

Breakthrough Feature Development: Support the implementation of "first-of-its-kind" functionalities, from advanced web-based interactivity to AI-augmented workflows.

UE5 Expansion & Learning: Actively learn the Unreal Engine 5 pipeline, eventually contributing to Blueprint scripting, performance profiling, and "polishing" project features.

Pipeline Automation: Author tools and scripts to automate workflows, improving efficiency across the CGI and development departments.

Documentation & Standards: Author and update technical documentation for tools and best practices to ensure team scalability.

Essential Skills & Qualifications (The Core)

Strong working knowledge of Frontend (e.g., React, Vue) and Backend (e.g., Node.js, Python, Databases) architectures.

Experience with C++, C#, Python, or other object-oriented languages.

Understanding of web technologies and communication protocols (e.g., JSON, WebSockets).

A dedicated team player with a "problem-solving first" attitude and a strong desire to master Unreal Engine 5.

Desired Skills & Qualifications

UE5 Curiosity: Any exposure to the Unreal Engine 5 pipeline (Blueprints, modeling/UV, lighting, or shading) is a massive plus, but not required—we will help you learn.

AI & Machine Learning Interest: Active interest in integrating AI/ML workflows into the production pipeline (e.g., Stable Diffusion/ComfyUI, AI upscaling, or LLM-driven tooling).

Profiling & Performance: Interest in learning performance optimization using tools like Unreal Insights.

Client Relations: Comfortable in client-facing environments, translating technical concepts into clear solutions.

Automotive Passion: Interest in high-end automotive visualization and vehicle technology.

Why Join Us?

Hybrid Innovation: Work at the intersection of high-scale web development and cutting-edge real-time 3D.

Career Transformation: Transition from a traditional developer to a specialized technical innovator in the UE5 and Pixel Streaming space.

High-Visibility Projects: Lead the development of breakthrough features on ambitious projects for world-class brands.

Culture of Learning: A culture focused on innovation, continuous learning, and technical excellence.
