Game developer

A game developer programmes the features that make a video game playable. They turn design ideas into behaviours, interactions and software systems, then check that they work. Their work may include game rules, interfaces, menus or the technical integration of visual and audio assets. The details depend on the project, the target platform and how work is divided within the team.

The role covers programming and maintaining the game, from building a new feature to fixing a fault. The developer tests their code, investigates the cause of a malfunction and improves how the game runs when technical constraints demand it. Playtesting may lead them to change an interaction or revise an implementation. This work involves regular discussion with the people who design the game, create its content and test it.

The title does not describe a single technical specialism. Depending on the need, the role may focus mainly on gameplay, engine systems or tools used to produce the game. The features to be assigned should therefore be specified before choosing languages, an engine and the expected level of autonomy. Managing programmers and making technology decisions for the team belong to a lead role when required; they cannot be inferred from the title “game developer” alone.

Game developer, game designer and tools programmer: who does what?

• The game designer designs the principles, rules and mechanics of the game. They set out the intended experience for the player.
• The game developer turns these requirements into code, integrates them into the game and fixes problems with how they work. They discuss matters with design when a technical solution requires a rule to be clarified.
• The tools programmer develops software that helps create game content. This specialism may be separate from gameplay programming.

In a small team, one person may cover several of these tasks. The job description should then specify what they will produce themselves and which decisions they will share with other disciplines.

Hiring a game developer addresses a specific programming need: making the planned rules, interactions and content work in the game. The right scope depends on what remains to be built and what is already in place. A team creating game mechanics will not necessarily seek the same experience as a team maintaining technical systems or building production tools.

A vague scope makes assessment difficult. If a job advert combines gameplay, engine work, interfaces and tools without distinguishing priorities, candidates may show interesting work that has little bearing on the responsibilities involved. Identify the priority features, target platform and disciplines with which the person will collaborate. This also clarifies how responsibilities are divided between programming and design.

How well the game works is another consideration. Testing, debugging and optimisation are integral to programming. A feature that appears ready may still fail during a playtest or behave differently across platforms. The person hired should be able to explain how they detect a problem, investigate its cause and verify a fix. For the recruiter, that process matters as much as a visible result on screen.

Hypothetical example: a team is planning new interactions and already has a game designer and artists. It might seek a developer who can implement the rules and integrate the assets, with a technical lead to approve architecture decisions. If it also expects that person to decide on technology and manage other programmers, it is describing lead responsibilities and should say so explicitly.

Finally, collaboration affects the quality of the result. A design intention must become a technically feasible solution, then be adjusted in response to testing. The recruitment brief should therefore clarify who sets out the requirements, who decides when a constraint arises and who tracks faults through to resolution.

• Programme game behaviours, actions and rules according to design requirements.
• Develop interactions between the player and the game environment.
• Create or adapt interfaces and menus within the scope of the role.
• Technically integrate visual and audio assets produced for the game.
• Test features and investigate the causes of identified faults.
• Fix bugs and maintain the systems assigned to the role.
• Optimise how the game runs on its target platforms.
• Adjust code in response to playtesting and discussions with other disciplines.

A computing background or specialist video game training can prepare someone for the role. The industry occupational framework mentions, among other routes, a French vocational bachelor's degree followed by a master's degree, engineering schools and video game schools. France Travail also lists the French BTS, DUT, BUT and vocational bachelor's degree in computing as possible foundations. These routes indicate skills and knowledge to look for; they do not establish a single qualification required for every role.

To assess an application, start with the work to be assigned. A game project may show how someone programmed a mechanic, integrated an interface or made visual and audio assets work. Ask which part they actually developed, what constraints they faced and how they checked the result. For a team project, distinguish their contribution from those of game design, art and other programmers.

Useful skills include programming, problem solving, use of a relevant engine or libraries, and writing technical explanations. Proficiency with a particular tool should be judged against the role's environment. Someone who has worked with another engine can show how they approach a new codebase; the recruiter can then decide which knowledge must be usable from day one.

Relevant experience is better understood through responsibilities already held than through years of experience alone. Has the person built a feature, fixed faults through to resolution or supported changes arising from playtesting? If the role involves managing programmers or making technology decisions for the team, seek evidence of those specific responsibilities. They fall within a lead remit and should not be assumed of every developer.

The following steps are assessment advice to adapt to the role's features, tools and level of autonomy.

1. Define criteria before interviews

List the tasks the person will actually perform: programming interactions, integrating assets, fixing faults or working on technical systems. Separate skills needed on arrival from those that can be learned with the team. Specify the platforms and development environment relevant to the project without turning a commonly used tool into a universal requirement.

Also clarify who will make technology decisions. If the role requires managing programmers, assess that responsibility as a separate criterion. Link each criterion in the assessment grid to a specific deliverable and exclude technologies unrelated to the features to be produced. During interviews, observe whether the candidate can explain how their technical choices supported the features they built.

2. Examine past work

Ask the candidate to choose a feature for which they can explain their personal contribution. What did the game designer request? Which part did the candidate programme? What assets did they integrate, and which constraints changed the implementation? Look for a clear sequence from requirement to code, test and adjustment.

Then examine a problem they encountered: how did they reproduce, isolate and fix it? A strong answer distinguishes observed facts, tested hypotheses and verification after the fix. Pay attention to collaborative projects: an impressive result alone does not prove that the candidate wrote or maintained the code shown.

3. Set a task close to the role

Choose a limited exercise that reflects an everyday decision. Hypothetical example: an interaction specified by design works in the first level but fails in another gameplay situation. Ask the candidate how they would investigate the cause, what tests they would run and how they would explain their fix.

Observe their method more than their knowledge of a particular engine, unless that tool is essential from day one. A positive sign is the ability to explain assumptions and verify the result. A warning sign is a proposed fix without diagnosis or a check that it works after the change.

4. Assess collaboration and autonomy

Present feedback from design, art or testing that calls for a feature to be revised. Ask what the candidate would clarify with each discipline and how they would communicate a technical constraint. Look for an accessible explanation accompanied by a concrete proposal or a question that helps the team decide.

Ask about a past technical decision: what freedom did the candidate have, and who approved the solution? This helps compare the autonomy they exercised with that required by the role. A warning sign is claiming sole credit for decisions that belonged to the team without explaining how responsibilities were shared.

5. Check references and divide assessment responsibilities

With the candidate's consent, ask someone who has worked with them to describe their role in a feature, how they dealt with faults and how they worked with other disciplines. Ask questions related to the role rather than seeking a general appraisal.

If the company lacks the expertise to assess code or technical diagnosis, involve someone technically competent on the project or an independent technical assessor. Give them the criteria established in step one and ask for reasoned observations. Keep the hiring decision tied to the stated responsibilities; do not let one test replace an examination of the candidate's actual work.
