3What this role really is

An Immersive Experience Developer builds the interactive features of virtual worlds and digital environments. This means taking designs and turning them into working features, whether that's a button press or a complex environmental interaction. It's a hands-on technical role, where the code written shapes how people experience and move through virtual spaces.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Unreal Engine (C++ / Blueprints) Intermediate

Developing interactive features, optimising performance, integrating assets, and debugging within the Unreal Editor. You'll be writing C++ code and using Blueprints for rapid prototyping.

Unity (C#) Intermediate

Building and optimising VR/AR applications, scripting interactions, managing scene hierarchies, and integrating third-party SDKs using C# within the Unity Editor.

Blender / Maya (Asset Integration & Optimisation) Intermediate

Importing, optimising (e.g., reducing poly count, fixing UVs), and exporting 3D models and animations from these tools into game engines. You won't be a full-time artist, but you'll need to tweak assets.

AWS / Azure (Basic Storage & Deployment) Basic

Uploading and downloading assets from cloud storage (like S3 or Blob storage) for project distribution or collaborative workflows. You might also help with basic deployment of server-side components.

Git / Perforce (Version Control) Intermediate

Managing code and large binary assets (like 3D models and textures) using version control systems. You'll be branching, merging, and resolving conflicts regularly.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Technical Approach for a Feature Proposes options, requires explicit approval from Senior Engineer. Independently decides on approach for routine features; consults Senior Engineer for novel or complex ones. Defines technical approach for entire systems; reviews and approves approaches from mid-level developers.
Asset Optimisation Strategy Executes optimisation steps as instructed by Senior Engineer or Artist. Identifies assets needing optimisation and proposes a plan to artists/Senior Engineer; executes agreed-upon optimisations. Defines overall asset optimisation pipeline and standards for the team.
Integration of New SDK/Tool Assists Senior Engineer with integration under close supervision. Researches and prototypes integration of minor SDKs/tools; requires approval from Senior Engineer/Lead Architect before full adoption. Evaluates and recommends major SDKs/tools for project adoption; leads integration efforts.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Bug Count (Critical/High)
The number of critical or high-priority bugs found in features you've delivered after they've been released to QA or users.
Target · Fewer than 5 critical bugs per feature shipped.

You ship a new avatar customisation system. If QA finds 3 critical bugs (e.g., crashes, broken functionality) and 1 high-priority bug (e.g., severe visual glitch), you're within target. If they find 6, we'll need to look at why.

Performance Budget Adherence
Ensuring the assets and code you integrate or create stay within the defined technical limits for poly count, draw calls, and script execution time to maintain target frame rates.
Target · Assets and features delivered within poly count and draw call limits 95% of the time, maintaining a minimum of 60 FPS on target hardware.

You're adding a new interactive object. If it pushes the scene's draw calls over budget, causing a frame rate drop, that's a miss. We'd expect you to optimise it or flag it early.

Task Completion Rate (Sprint Velocity)
The percentage of assigned development tasks (Jira tickets, for example) that you complete within the agreed-upon sprint timeframe.
Target · Completes 90% of assigned tasks within the sprint cycle.

If you're assigned 10 tasks in a sprint, we'd expect 9 of them to be marked 'done'. If you consistently miss this, we'll work with you to understand why and adjust workload or support.

Code Quality & Maintainability
How clean, well-structured, and easy to understand your code is, including adherence to coding standards and good commenting.
  • Positive feedback during code reviews from Senior Engineers
  • minimal refactoring needed by others
  • clear, concise comments and documentation
  • low technical debt contribution.
Collaboration Effectiveness
How well you work with other team members—artists, designers, and other developers—to get features built and problems solved.
  • Proactively asking for clarification from designers
  • offering constructive feedback in code reviews
  • actively participating in stand-ups and planning sessions
  • positive feedback from peers on cross-functional tasks.
Problem Solving & Proactivity
Your ability to identify technical issues early, propose sensible solutions, and take initiative to improve processes or code.
  • Flagging potential integration issues before they become blockers
  • suggesting optimisations for existing code
  • independently researching solutions to tricky bugs
  • taking ownership of a problem from identification to resolution.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Building Tangible Experiences

You love seeing your code come to life in a 3D environment, knowing that users will physically interact with what you've built. The idea of creating something immersive and interactive genuinely excites you.

Spending an extra hour optimising a character's movement system because you know it'll make the experience feel more fluid and natural for the player.

Solving Technical Puzzles

Complex bugs or performance bottlenecks don't frustrate you; they challenge you. You enjoy the process of dissecting a problem, researching solutions, and implementing elegant fixes.

Spending a morning deep-diving into a shader issue that's causing visual artefacts, eventually finding a clever workaround or optimisation.

Learning New Technologies

You're keen to explore new SDKs, game engine features, or Web3 protocols. The rapidly evolving nature of immersive tech is a draw, not a deterrent.

Volunteering to research and prototype a new haptic feedback system, even if it's not on the immediate roadmap, just to see what's possible.

What frustrates people
  • The Hype Whiplash (scaled down): Getting excited about a new tech, only for it to be deprioritised or deemed 'too early' by leadership.
  • Platform Instability: A key SDK update from Meta or Epic Games breaks a core feature you just built, forcing a quick scramble to fix it.
  • Explaining the Value of 'Nothing': Having to justify why a virtual interaction or asset is important to someone who just sees it as 'a game'.
  • Messy Assets: Receiving 3D models from artists that aren't optimised for real-time performance, requiring you to clean them up.
What this role does not give you
  • A static, unchanging technical environment; expect constant evolution.
  • A role where you're just executing; you'll need to think about how to build things and suggest improvements.
  • Complete creative freedom without technical constraints or performance budgets; you'll work within defined parameters.

8Who you work with

Your work directly influences the quality and stability of our immersive products. You're building the interactive layer that users engage with, so your code needs to be solid. Good experiences mean happy users and better adoption of our metaverse initiatives. Poor execution could lead to negative user sentiment and a perception that our metaverse efforts are just 'fluff' or 'another video game', which, frankly, we're trying to avoid.

Inside the business
  • Senior Metaverse Engineers (your direct manager and peers)
  • 3D Artists & Modellers (who hand over assets)
  • UX/UI Designers (who define the user journey)
  • Product Managers (who define the 'what' and 'why' of features)
  • QA Testers (who'll try to break your code)
Outside the business
  • Hardware vendors (e.g., Meta, Apple for SDK updates)
  • Engine providers (e.g., Epic Games for Unreal Engine updates)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • Solid grasp of object-oriented programming principles, ideally in C++ or C#.
  • Proven ability to build and ship interactive 3D experiences, even if they're personal projects or game jams.
  • Familiarity with 3D mathematics (vectors, matrices, quaternions) for transformations and spatial calculations.
  • Experience with debugging complex software systems and optimising for performance.

10What to practise next

Where the job is going, and what to do about it starting this week.

Real-time Ray Tracing Optimisation

As GPU hardware advances, real-time ray tracing is becoming more prevalent, offering incredibly realistic lighting and reflections. Understanding how to implement and optimise this without killing performance will be crucial for next-gen immersive experiences.

Ray tracing vs. rasterisation · BVH (Bounding Volume Hierarchy) structures · Denoising techniques · Hybrid rendering pipelines · GPU architecture for ray tracing

  • This month: Explore the ray tracing features in Unreal Engine 5 or Unity's HDRP and experiment with simple scenes.
  • Month 2: Read documentation and tutorials on optimising ray-traced scenes, focusing on performance budgets.
  • Month 3: Try to implement a small feature that uses ray tracing and benchmark its performance on different hardware.
  • Month 4: Participate in online forums or communities discussing real-time ray tracing techniques.

Quick win: Enable ray tracing in a sample project and observe its impact on performance and visual quality. Start tweaking settings to see the immediate effects.

Decentralised Identity & Wallet Integration

As Web3 concepts mature, users will expect more control over their digital identities and assets across different virtual worlds. Integrating decentralised identity solutions will become standard for secure, interoperable experiences.

Self-Sovereign Identity (SSI) · Verifiable Credentials (VCs) · Wallet Connect protocols · On-chain vs. Off-chain authentication · User data privacy in Web3

  • This month: Set up a MetaMask or Phantom wallet and interact with a few dApps on a testnet to understand the user experience.
  • Month 2: Research different decentralised identity frameworks (e.g., DID, Verida) and their potential for immersive apps.
  • Month 3: Prototype a simple login system in Unity/Unreal that uses Wallet Connect to authenticate a user.
  • Month 4: Read up on best practices for securing user data and digital assets in Web3 environments.

Quick win: Integrate a basic Web3 wallet connection into a simple demo app. It's a great way to understand the practicalities without building a full identity system.

11Staying current once you are in

What people here do to keep up
  • Participating in game jams or hackathons to rapidly prototype new ideas and learn new skills under pressure.
  • Contributing to open-source projects related to immersive tech or game development.
  • Attending industry conferences (e.g., GDC, AWE) or local meetups to network and stay updated on trends.
  • Completing online courses or specialisations in advanced 3D graphics, real-time rendering, or Web3 development.

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine having a super-smart assistant that handles the tedious bits of immersive development, letting you focus on the fun, creative challenges. That's what AI can do for you here.

In this role, we're not just talking about AI as a buzzword; we're actively using it to make our development process faster, smarter, and frankly, more enjoyable. From generating placeholder assets to analysing user behaviour, AI is becoming an indispensable tool in our technical toolkit. You'll be expected to get comfortable with these tools pretty quickly, because they're genuinely game-changers.

3D Asset Generation Automation

Use text-to-3D and image-to-3D AI models (like Luma AI or Meshy) to rapidly generate prototype assets and environmental textures. This drastically cuts down on manual modelling time for early-stage concepts, letting you quickly test ideas without waiting for a full art pass. Think of it as having an instant placeholder artist.

Virtual Behavior Analysis

Deploy AI agents to analyse user behaviour within virtual environments. This means generating heatmaps of where users look, identifying points of confusion in user flows, and predicting which virtual items or interactions will be most popular. It helps you iterate on your features much faster, based on real (virtual) data.

R&D Synthesis Engine

Use a specialised LLM agent to constantly scan, synthesise, and summarise technical whitepapers, competitor platform updates, and new Web3 protocols. This delivers a weekly intelligence briefing on critical threats and opportunities, keeping you up-to-date with the bleeding edge without spending hours trawling the internet.

Code & Documentation Drafting

Use AI coding assistants (like GitHub Copilot or similar) to generate boilerplate code, suggest optimisations, and even help with debugging. Beyond code, AI can draft first passes of technical documentation for your features, saving you the tedious task of writing it from scratch.
