3What this role really is

A Junior UI Programmer writes the code behind menus, health bars and quest logs in a game. You build the player's window into the game, working with programmers and designers to shape how players see and interact with it.

4What you'd actually use

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

Unreal Engine (UMG) or Unity Engine (UGUI/UI Toolkit) Intermediate

Implementing new UI widgets, connecting them to game data, debugging visual issues, and navigating the engine's UI editor.

C++ or C# Programming Language Intermediate

Writing clean, functional code for UI components, implementing game logic hooks, and debugging runtime issues. We're looking for solid fundamentals.

Git or Perforce (Version Control) Basic

Committing your code changes, pulling updates from the team, pushing your work, and resolving simple merge conflicts. Following our branching strategy is key.

Figma or Adobe XD (Design Inspection) Basic

Inspecting design mockups to extract pixel values, font sizes, colours, and asset specifications to accurately implement UI elements.

Unreal Insights or Unity Profiler (Performance Tools) Basic

Running the profiler to identify basic performance bottlenecks in your UI code, such as high draw calls or unexpected memory allocations, with guidance.

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 New UI Widget Escalate to Senior UI Programmer for guidance and approval. You'll propose an idea, but they'll make the final call. Propose a solution to the Lead UI Programmer, discuss trade-offs, and get their agreement before proceeding. Define the technical approach, consult with Lead/Architect, then proceed with implementation.
Bug Prioritisation Work on bugs as assigned by your Senior Programmer or Lead. If you spot something critical, flag it immediately. Prioritise your own bug queue based on project needs, but consult with Lead on high-impact issues. Prioritise bugs for your workstream, negotiate with QA/Production on critical fixes.
Code Style & Standards Strictly follow existing coding standards. Any deviation requires explicit approval from Senior/Lead. Adhere to standards; may propose minor improvements for discussion with the team. Enforce coding standards, lead discussions on improvements, update style guides.
Asset Integration (UI textures, fonts) Integrate assets as provided by the Art team, following established pipeline. Report any issues. Integrate assets, troubleshoot minor pipeline issues, suggest optimisations to Art team. Define asset integration pipeline, work with Art/Tech Art on optimisations and tooling.

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
The percentage of assigned UI tickets (bugs, new features) that you finish within the estimated sprint timeframe.
Target · 85%+ within sprint estimates

If you're assigned 10 UI tasks in a sprint and complete 9 of them on time, that's a 90% completion rate. We'll look at the complexity too, of course.

Bug Re-open Rate
How often bugs you've 'fixed' are actually re-opened by our QA team because the issue wasn't fully resolved or a new one was introduced.
Target · Less than 15% of your fixed bugs are re-opened

You fix 20 UI bugs in a month. If 3 of those get re-opened by QA, your re-open rate is 15%. The goal is to get it right the first time, or at least the second!

Code Review Feedback Incorporation
How effectively and quickly you take on board feedback from code reviews by senior programmers and apply it to your work.
Target · 90%+ of critical feedback addressed, with decreasing need for similar feedback over time.

If a senior highlights a common memory leak pattern in your code, we'd expect you to not make that same mistake in the next few code reviews. It's about learning, not just fixing.

Implementation Fidelity
How closely your implemented UI elements match the pixel-perfect designs provided by the UI artists and designers.
Target · <10% rework required from design review, decreasing over time.

You build a new settings menu. If the designer only has to point out a couple of minor alignment issues or font size discrepancies, that's great. If they need you to redo half the screen, we'll need to look at why.

Proactive Learning & Asking Questions
You're actively seeking out knowledge, trying to solve problems yourself first, and then asking well-thought-out questions when you're genuinely stuck. You're not just waiting to be told what to do.
  • You'll be seen researching documentation, looking at existing code, and coming to your mentor with specific questions rather than vague 'I don't know how to do this'. You'll also share interesting things you've learned with the team.
Adherence to Coding Standards
Your code is clean, readable, well-commented, and follows the team's established style guides and best practices. It's not just about getting it to work, it's about making it maintainable.
  • Code reviews will consistently show your code is easy to understand, uses consistent naming conventions, and doesn't introduce unnecessary complexity. You'll also be mindful of performance implications, even at a junior level.
Collaboration & Communication
You're communicating clearly with your team members, especially UI designers and other programmers. You're quick to flag blockers or potential issues, and you're open to feedback.
  • You'll be actively participating in stand-ups, asking designers clarifying questions early in the process, and letting your Senior Programmer know if a task is taking longer than expected before it becomes a crisis. No surprises, please.
Ownership of Small Tasks
Even for smaller tasks, you take responsibility for seeing them through from start to finish, including testing your own work before handing it over to QA.
  • You won't just 'throw it over the fence'. You'll make sure your UI elements are hooked up correctly, that they behave as expected, and that you've done a quick sanity check before marking a task as done.

7Would you like it

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

What people enjoy
Learning & Growth

You'll be excited to dive into new parts of the engine, learn new coding patterns, and soak up knowledge from senior team members. Every bug fix is a lesson, every new feature an opportunity to expand your skillset.

Spending an extra hour after work reading engine documentation or trying out a new UI technique you saw online, just because you're curious.

Tangible Impact

You love seeing your code come to life on screen. The immediate visual feedback of building a menu or animating a health bar is what gets you going. You want to contribute to something players will actually see and interact with.

The satisfaction of seeing a new UI element you coded appear perfectly in the game, knowing thousands will use it.

Team Contribution

You enjoy being part of a team, contributing your piece to a larger puzzle. You're happy to help out where needed and celebrate collective successes, even if your part is small.

Volunteering to take on a tricky bug fix that's blocking a designer, just to help the team keep moving forward.

What frustrates people
  • The 'Pixel-Perfect' Paradox: Spending ages on a detail only for the design to change.
  • Last-Minute Localization Nightmare: Text strings breaking layouts just before release.
  • Fighting the Engine: When built-in UI tools just don't want to do what you need.
  • Vague Feedback: Translating 'more juice' into actual code and animations.
  • Performance Scapegoat: UI often gets blamed first for frame rate drops.
  • Scope Creep via Polish: Simple screens slowly morphing into complex, animated features.
What this role does not give you
  • Complete creative freedom over UI design (that's the designer's job, you implement it).
  • A perfectly stable, unchanging set of requirements (game dev is iterative by nature).
  • A quiet, solitary coding experience (you'll be talking to a lot of people).
  • Immediate recognition for every single line of code (it's a team effort, and your work is part of a bigger picture).

8Who you work with

Your work directly impacts the player's first impression and ongoing interaction with our games. A smooth, responsive, and visually appealing UI is absolutely crucial for player retention and overall game quality. You'll be contributing to the foundation of that experience, making sure the building blocks are solid and well-implemented.

Inside the business
  • Senior UI Programmers (for mentorship and guidance)
  • UI Designers (to understand design intent and provide feedback)
  • QA Testers (they'll be finding your bugs, so you'll work closely with them)
  • Gameplay Programmers (to connect UI elements to game logic)
  • Art Team (for assets, animations, and visual polish)
Outside the business
  • None directly in this role. Your focus is internal development.

9What you need before you start

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

  • A solid grasp of fundamental programming concepts (data structures, algorithms, object-oriented programming) in C++ or C#.
  • Some practical experience with a game engine (Unreal or Unity), even if it's from personal projects or university assignments.
  • An understanding of what makes good UI in games, probably from playing a lot of them and thinking about how they work.
  • The ability to work effectively in a team, communicate clearly, and take on feedback.
  • A genuine passion for video games and game development – it's a tough industry, and passion helps a lot.

10What to practise next

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

Advanced Game Engine UI Systems

You'll move beyond just using the built-in UI editor to understanding how to create custom UI components, extend engine functionality (e.g., custom Slate widgets in Unreal, advanced UI Toolkit features in Unity), and deeply optimise for performance. This is where you really start to master the tools.

Custom Widget Creation · UI Rendering Pipeline · Engine Integration · Performance Optimisation Techniques

  • This week: Read through the official documentation on custom UI elements (e.g., Unreal Slate or Unity UI Toolkit scripting) in your engine.
  • This month: Try to implement a simple custom UI widget from scratch, without relying on the visual editor, to understand the underlying code.
  • Month 2: Take an existing complex UI screen in our game and try to identify 2-3 areas where its performance could be improved, then discuss with your mentor.
  • Month 3: Experiment with different UI rendering options or materials to see their performance impact and visual quality trade-offs.

Quick win: Volunteer to fix a tricky UI bug that requires digging into the engine's source code or a custom material. It's a great way to learn by doing.

11Staying current once you are in

What people here do to keep up
  • Participate in game jams: They're brilliant for quickly learning new skills, working under pressure, and building a portfolio.
  • Contribute to open-source game projects: A great way to get real-world coding experience and collaborate with others.
  • Follow game development blogs and tutorials: Stay up-to-date with new techniques, engine features, and industry trends.
  • Attend industry conferences or local meetups (online or in-person): Network with other developers and learn from experts.
  • Build personal game projects: Nothing beats hands-on experience for solidifying your skills and exploring new ideas.

Working with AI on the job

Working with AI

Where AI is starting to help

As a Junior UI Programmer, you're here to learn and build. The good news is, AI isn't here to replace you; it's here to be your super-smart assistant, helping you get up to speed faster and tackle tasks with more confidence. Imagine having a senior programmer looking over your shoulder 24/7, ready to offer code snippets or spot potential issues. That's roughly what AI can do for you.

In the world of game UI programming, AI tools can seriously cut down on the tedious, repetitive bits, letting you focus on the interesting challenges and learning opportunities. You'll be able to generate boilerplate code, prototype layouts, and even catch potential issues before they become big problems. It's about working smarter, not harder, right from the start of your career.

UI Component Boilerplate Generation

Use tools like GitHub Copilot, trained on our project's codebase, to instantly generate the C++/C# boilerplate code for new UI widgets. Just type a comment like '// Create a UMG widget for a settings slider with a label, value text, and reset button', and watch the magic happen. It's like having a coding buddy who knows all the common patterns.

AI-Assisted Layout Prototyping

Imagine converting a rough sketch or a Figma wireframe directly into a functional, engine-ready UI layout file (like a UMG widget or Unity prefab). Emerging AI tools can give you a first-pass implementation in minutes, rather than hours, letting you iterate on designs much faster and learn layout principles by example.

Proactive Localization Testing

Integrate an AI service that scans your UI screens and automatically simulates how longer text strings from languages like German or Polish might break your layouts. It'll flag potential text overflow issues before they ever reach a human translator or QA tester, saving you a huge headache later on.

Automated Code & Documentation Suggestions

Beyond generating code, AI can suggest improvements to your existing code for readability or performance. It can also help draft comments or explain complex functions, making your code easier to understand for others and helping you learn best practices on the fly.
