3What this role really is

An XR developer builds virtual and augmented reality experiences, writing code that turns designs into interactive 3D worlds. The work involves using C# or C++ to construct spaces users can step into. It is hands-on, problem-solving work, figuring out how to make things run smoothly and feel real.

4What you'd actually use

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

Unity Engine Intermediate

Building scenes, implementing pre-existing components, writing C# scripts for gameplay logic, and configuring XR settings for various platforms. You'll be spending a lot of time in the editor.

Unreal Engine (C++ & Blueprints) Intermediate

Developing interactive experiences using a mix of C++ and Blueprints, setting up physics, animation, and rendering pipelines. You'll work with the engine's core systems to create immersive environments.

C# (for Unity) / C++ (for Unreal) Intermediate

Writing clean, efficient code to implement game mechanics, UI logic, networking, and custom XR interactions. This is your primary language for building features.

Meta Quest SDK / OpenXR / ARKit / ARCore Intermediate

Implementing platform-specific features like hand tracking, passthrough AR, spatial anchors, and controller input using the relevant SDK APIs. You'll need to know the quirks of each.

Git (GitHub/GitLab) Intermediate

Managing your code with branching, merging, pull requests, and resolving conflicts. You'll need to be comfortable with Git LFS for handling large binary assets like 3D models and textures.

Jira / Asana Advanced

Tracking tasks, updating progress, participating in sprint planning and retrospectives, and ensuring your work is aligned with project timelines. Keeping your tickets up-to-date is crucial.

Blender / Autodesk Maya (Import & Configuration) Basic

Importing and configuring 3D models, textures, and animations provided by artists. You'll need to understand basic material setup and asset optimisation principles.

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 Follows prescribed approach; escalates if unsure. Chooses best approach for assigned feature; consults senior on novel techniques. Defines technical approach for entire workstream; approves junior's approaches.
Code Optimisation Strategy Applies basic optimisations under guidance. Independently identifies and implements optimisations for features; consults on system-wide changes. Defines optimisation strategies and standards for the team; mentors others on profiling.
Bug Prioritisation Fixes assigned bugs; escalates priority questions. Prioritises P2/P3 bugs for owned features; flags P1s to senior immediately. Helps define bug prioritisation for workstream; makes calls on P1 bug allocation.
Tool/Library Selection (within project) Uses existing approved tools. Researches and proposes new libraries for specific feature needs (e.g., a new physics library); requires senior approval. Approves new tools/libraries for workstream; evaluates broader impact.

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.

Task Completion Rate
Successfully completing assigned Jira tickets within the sprint timeframe.
Target · 90%+ of P1/P2 tickets completed per sprint

If you're assigned 10 high-priority tasks in a sprint, you'd be expected to finish at least 9 of them, including all necessary code reviews and testing.

Bug Resolution Time
The average time it takes to fix and verify bugs of a certain priority level.
Target · P2 bugs fixed within 72 hours; P3 bugs within 5 working days

A reported UI glitch (P2) on Monday should be fixed and ready for QA by Thursday morning at the latest.

Performance Compliance
Ensuring your implemented features consistently meet our target frame rate on the specified hardware.
Target · >90 frames per second (FPS) on target hardware (e.g., Meta Quest 3)

After integrating a new interaction system, profiling shows the scene still runs at a steady 90 FPS, without any noticeable drops or hitches during user testing.

Code Review Feedback Incorporation
How quickly and effectively you address feedback from code reviews.
Target · All critical/major review comments addressed within 24 hours (P1) or 48 hours (P2)

If a Senior Developer flags a potential performance issue in your pull request, you'd be expected to investigate and push a fix or a clear explanation within a day.

Feature Robustness
How well your implemented features handle edge cases and unexpected user input without breaking.
  • Few post-release bug reports related to your features. QA reports fewer critical bugs during testing. Your code is clean, well-structured, and includes appropriate error handling for common scenarios.
Collaboration with Design & Art
Working effectively with XR Designers and 3D Artists to translate their vision into technical reality.
  • Designers and artists frequently comment on your proactive communication and willingness to find technical solutions for creative challenges. You're seen as a partner, not just a code implementer. You ask clarifying questions early on.
Proactive Problem Identification
Spotting potential technical issues or performance bottlenecks before they become major problems.
  • You bring up potential issues in stand-ups or team meetings before they're discovered by QA. You suggest optimisations or alternative approaches during feature planning. You're not just fixing what's broken, you're trying to prevent it.
Contribution to Team Knowledge
Sharing your learnings and helping other team members.
  • You contribute to internal documentation, share useful articles or techniques in team chats, and offer informal help to newer team members. You're seen as someone who helps lift the whole team up.

7Would you like it

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

What people enjoy
Building Tangible Experiences

You get a real kick out of seeing your code transform into a virtual world or an AR overlay that people can actually interact with. The immediate feedback of putting on a headset and seeing your work come alive is a huge driver.

Spending an afternoon refining a hand-tracking interaction, then putting on the headset and experiencing it feel perfectly natural and responsive, is incredibly satisfying.

Solving Hard Technical Puzzles

You thrive on the challenge of figuring out why something isn't working, especially when it involves complex 3D maths or obscure hardware quirks. Debugging a tricky performance bottleneck is your idea of a good time.

Successfully optimising a scene to hit 90 FPS after days of profiling and tweaking shaders, knowing you've squeezed every bit of performance out of the hardware.

Being on the Bleeding Edge

The idea of working with new, unproven technologies and shaping the future of spatial computing excites you. You're happy to learn new SDKs and experiment with new hardware, even if it means dealing with instability.

Being among the first to experiment with a new AR cloud API or a novel haptic feedback device, and figuring out how to integrate it into a project.

What frustrates people
  • The 'Tyranny of the Performance Budget': Spending half your time optimising code and art assets to run on what's essentially a mobile phone strapped to someone's face (like a Meta Quest).
  • SDK Whiplash: Platform holders constantly releasing new, often beta-quality, SDKs and deprecating old ones with little notice, forcing you to refactor major parts of your application just to keep it working.
  • Hardware Fragmentation Hell: A feature that works perfectly on a Quest 2 causes crashes on a Pico 4, looks wrong on a Vive Pro, and has tracking glitches on a HoloLens 2. You'll become a part-time hardware QA tester.
  • Explaining Physics to Product Managers: The recurring, soul-crushing conversation where you have to explain why you can't have 100 photorealistic, physically-simulated characters in a scene running on a standalone headset without it turning into a slideshow.
  • Physical and Mental Fatigue: Literally getting headaches, neck strain, and eye fatigue from wearing headsets for hours on end to build and test the very experiences you're creating.
What this role does not give you
  • Absolute stability in tools and platforms – things change rapidly here.
  • A strictly '9-to-5' coding environment without occasional urgent fixes or late nights to hit a demo deadline.
  • The luxury of always working on greenfield projects; you'll spend time maintaining and optimising existing code too.
  • A role where you can avoid wearing a headset for extended periods during development and testing.

8Who you work with

This role directly impacts the quality and stability of our XR products. Your work ensures that features are delivered on time and perform as expected, which in turn affects user satisfaction, retention, and ultimately, our reputation in the immersive tech space. Get it right, and we build a loyal user base; get it wrong, and we're just another buggy app in a crowded market.

Inside the business
  • Senior XR Developers
  • XR Designers
  • 3D Artists
  • QA Engineers
  • Product Managers (for feature requirements)
Outside the business
  • Hardware platform providers (e.g., Meta, Valve, Pico) for SDK updates
  • External asset creators (occasionally)

9What you need before you start

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

  • At least 2 years of professional experience in game development, real-time 3D, or XR development.
  • Proven ability to independently implement features in Unity or Unreal Engine using C# or C++.
  • A strong portfolio or demonstrable projects showcasing your XR development skills (e.g., GitHub repo, personal projects, published apps).
  • Solid understanding of 3D mathematics (vectors, matrices, quaternions).
  • Experience with version control systems, particularly Git, and handling large binary assets.
  • A genuine passion for immersive technologies and a drive to learn and adapt in a rapidly evolving field.

10What to practise next

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

Advanced XR Graphics & Rendering Pipelines

As hardware gets more powerful, and users demand higher fidelity, understanding how to squeeze every bit of visual performance out of the GPU will become even more critical. This means going beyond basic materials and into custom rendering techniques.

Custom rendering pipelines (e.g., Unity's URP/HDRP · Advanced shader development (HLSL/GLSL, compute sh · Global illumination and real-time ray tracing in X · Foveated rendering and eye-tracked optimisations · Post-processing effects for immersive visuals

  • This week: Dive into the documentation for your engine's rendering pipeline (URP/HDRP or Unreal's renderer).
  • This month: Try writing a simple custom shader to achieve a specific visual effect.
  • Month 2: Experiment with foveated rendering settings on a target device if available.
  • Month 3: Benchmark different rendering techniques for performance impact on XR hardware.

Quick win: Spend an hour or two exploring the different post-processing effects available in your engine and see how they impact visual quality and performance in an XR scene.

Cross-Platform XR Development & Abstraction Layers

The XR market is still fragmented, with many different headsets and platforms. Being able to develop once and deploy everywhere, or at least with minimal changes, will save immense development time and unlock broader audiences.

OpenXR standard and its role in cross-platform dev · Developing custom abstraction layers for input, re · Platform-specific optimisations within a unified c · Build pipeline automation for multiple XR targets · Managing platform-specific asset variations

  • This week: Read up on OpenXR and its architecture.
  • This month: Try building a simple XR app that targets two different platforms (e.g., Quest and PCVR) using OpenXR.
  • Month 2: Research existing cross-platform XR frameworks or libraries.
  • Month 3: Design a simple input abstraction layer that works for both hand tracking and controller input.

Quick win: Ensure all new input code you write uses an abstract input system (like Unity's Input System or OpenXR input) rather than direct SDK calls, making it easier to swap platforms later.

11Staying current once you are in

What people here do to keep up
  • Actively participate in XR developer communities (e.g., local meetups, online forums, Discord servers).
  • Contribute to open-source XR projects on GitHub.
  • Attend industry conferences and workshops (e.g., GDC, AWE, XRDC) to stay current with trends and network.
  • Dedicate time to personal XR projects or game jams to experiment with new technologies and hone your skills.
  • Follow key XR thought leaders and technical blogs for insights into emerging techniques and best practices.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, XR development is complex, time-consuming, and often involves a lot of repetitive tasks. But what if you could offload some of that grunt work to AI? Imagine spending less time on boilerplate code or sifting through dense documentation, and more time actually building groundbreaking experiences.

Our team is actively exploring and integrating AI tools to make your job as an XR Developer more efficient and frankly, more fun. We're not talking about replacing you; we're talking about giving you superpowers. Here's how AI can genuinely boost your productivity day-to-day:

Automated Code & Asset Scaffolding

Use AI tools like GitHub Copilot to whip up boilerplate C# or C++ code for common XR interactions (think grabbing objects, UI pointers, or basic locomotion). Generative AI can even create placeholder 3D models, textures, and sound effects from simple text prompts, letting you prototype ideas in minutes instead of hours.

Intelligent Performance Profiling

Leverage AI-powered profilers that don't just show you a spike in frame time, but actually analyse the data and suggest probable causes. Instead of manually digging through hundreds of draw calls, AI might tell you, 'High draw calls from transparent shaders in the particle system are likely the culprit.' This cuts down complex debugging time significantly.

Accelerated R&D and SDK Analysis

Imagine using an AI assistant to summarise dense technical documentation for a new Meta Quest SDK, or to quickly compare the feature sets of competing ARKit and ARCore updates. This means less time reading and more time implementing, helping you stay ahead of the curve and make informed technical decisions faster.

Generative Testing & World Building

AI can procedurally generate complex test environments and scenarios. This helps us find those tricky edge-case bugs in physics or interaction systems that manual QA might miss. It can also populate large virtual worlds with varied, non-repeating scenery, saving our artists and designers significant time on environmental setup.
