[Hiring] Unreal Engine Engineer @Journi

Role Description

We’re looking for a Mid–Senior Unreal Engine Engineer to join this mission — someone who enjoys working hands-on at the intersection of real-time 3D, web interfaces, and large-scale systems.

The platform helps architects, developers, and planners visualize, analyze, and collaborate on urban environments in real time, combining spatial data with highly detailed 3D models to support smarter city planning and decision-making.

You’ll be helping shape the core of a real-time 3D streaming platform, with a strong focus on web-based experiences powered by Unreal Engine pixel streaming. Your work will directly impact how users:

• Explore interactive city-scale 3D environments
• Visualise and analyse complex spatial data
• Collaborate around urban planning decisions in real time

What you’ll do:

• Build and maintain features for a high-performance 3D streaming platform
• Develop web-based interfaces and UI for Unreal Engine pixel streaming
• Design and manage CI/CD workflows using Horde
• Work on server-side rendering infrastructure
• Improve system performance for high-load / high-scale environments
• Contribute to cloud infrastructure across AWS, Azure, or GCP
• Implement and maintain Infrastructure as Code (IaC)
• Support and optimise 3D asset pipelines
• Collaborate closely with cross-functional teams in a distributed setup

Qualifications

• Strong experience with Unreal Engine (UE4/UE5)
• Hands-on work with pixel streaming architectures
• Experience with Horde CI/CD
• Solid understanding of web technologies and UI development
• Experience with public cloud platforms (AWS / Azure / GCP)
• Familiarity with Infrastructure as Code
• Experience with server rendering infrastructure
• Proven experience working with high load / distributed systems
• Understanding of 3D asset pipeline management

Requirements

• Experience building interactive 3D web applications (Nice to have)
• Background in real-time rendering, gaming, or simulation platforms (Nice to have)
• Exposure to digital twin / geospatial / visualization tools (Nice to have)

Working Setup

• Contractor role -- 3 months
• 100% remote
• Collaboration with a UK-based client (some time zones overlap expected)

Why you'll love the role?

This isn’t just another Unreal role — you’ll be working on a product that brings entire cities to life in 3D. You’ll be part of building something that sits at the intersection of:

• real-time rendering
• spatial / city-scale data
• and web-based user experiences
