Cityscape Digital is a leading architectural visualisation studio located in London Bridge, on Bermondsey Street. We produce some of the highest-quality visuals, interactive VR and film in the industry, working with the world’s top architects and property developers. We are famed for our inclusive environment and respect for artistry from any creative background and are always looking for a good fit for our culture.

Job Description

We are looking for a UE Developer, specialising in Unreal Engine, to work with us on the delivery of key projects aiming to push the engine to the limit within the architectural space. This opportunity would suit a candidate who is technically strong in Unreal Engine, Blueprints, Python and C++. Experience in real-time rendering, interactive visualisations, or performance optimisation is desirable but not essential. A passion for real-time technology and excellent attention to detail with strong communication skills is key, as is having the confidence to liaise directly with clients, consultants and architects whilst working as part of our valued team.

• Tools & Procedural Pipelines: Design and build custom internal production tools, automation scripts, and procedural systems, utilising Unreal PCG to automate and streamline artists' workflows.
• Performance & Optimisation: Profile, benchmark, and debug real-time application performance on target PC hardware. Apply memory management, draw-call reduction, and frame-rate optimisation strategies.
• Engine AI & Automation: Code and integrate AI agent behaviours, logic workflows, and automated testing/execution features directly within the engine.

Web & Full-Stack Development (Desirable)

• API Architecture & Integrations: Connect real-time engine applications to external data services by designing, building, and maintaining RESTful or GraphQL APIs and backend integrations (utilising web fundamentals like JavaScript/Node.js).
• Full-Stack Application Delivery: Architect and deploy end-to-end web applications incorporating responsive React frontends, robust SQL database schemas, and industry-standard security protocols (authentication, encryption, CORS).

Technical Project Management & Delivery

• Agile Execution: Proven track record leading sprint planning, task allocation, issue triage, and milestone delivery using Jira and structured tracking frameworks.
• Version Control: Experience using Perforce for robust pipeline and asset management.
• Technical Feasibility & Standards: Conduct risk assessments, benchmarking, and prototyping to establish clear pipeline standards and technical guidelines prior to project rollout.
• Documentation & QA: Maintain detailed technical documentation (architecture diagrams, API specs, deployment guides) and report routinely on application performance metrics and system stability.
