Behind every great game, there is groundbreaking tech and a vision brought to life. If you're the kind of person driven by a pure passion for building, this summer could be different.

Welcome to Builders Lab, our internship program at Gameloft Bucharest.

This program is designed around you and your potential. Because true builders learn by doing, this is your chance to step inside a true hub for technology and innovation, and experience it firsthand.

Builders Lab is a hands-on journey where you get to prove your skills by actually creating something real.

If you bring a proactive, problem-solving mindset and a drive to build real products and meaningful experiences for millions of players worldwide, this is your space to turn those ideas into reality.

If your application is shortlisted, you’ll be invited to the final stage of our selection process:a live hackathon on June 16 – 17, from 10:00 to 17:00, in our studio. This is where you'll get to show your skills in action, and where we’ll select the final interns joining our team. You’ll be working in cross-functional teams to engineer a gaming platform from scratch. It's a real studio environment where you get to brainstorm, debate, and build side-by-side, supported by our mentors.

Shape your career with our internship roles, experience our true studio culture from the inside, and start building.

Role Purpose

Join the team that builds the cross-platform libraries, SDKs and developer tools used across all our games.

Our team focuses on building cross-platform C++ libraries and SDKs for mobile (iOS / Android), Windows, and console platforms (PlayStation, Xbox, Nintendo Switch), as well as internal tools, web tools, and R&D initiatives for new and interesting topics.

As part of the team, you will experience what it means to be the backbone behind every great game. Your focus within the team will depend on your interests and strengths.

You will learn how code evolves into a stable, versioned product used by multiple teams, rather than a standalone feature.

Responsibilities

• Implement features, improvements, and bug fixes in existing cross-platform C++ SDKs.
• Write and maintain integration examples, sample applications, unit tests and integration tests.
• Contribute to internal tools and webtools that improve productivity across game and publishing teams.
• Investigate and reproduce issues reported by teams using our SDKs; document findings and fixes.
• Participate in R&D spikes by prototyping ideas or PoCs (Proof of Concept), evaluating libraries/approaches and presenting trade-offs.
• Write and improve technical documentation for APIs, tools and workflows.

What You Will Learn

• How a cross-platform SDK is designed, versioned and shipped to production.
• Real-world C++ practices in game development (memory management, build systems, platform-specific behavior on iOS, Android, Windows and Consoles).
• Principles of good API design: naming, error handling, backwards compatibility, deprecation strategies.
• Debugging across complex stacks: native code, mobile platforms and CI/build systems.
• How to translate unclear requirements into well-scoped technical tasks.
• Code review practices, technical writing and presenting technical trade-offs.

Candidate Profile – Must Have

• Strong programming fundamentals in at least one mainstream language (C++, C#, Objective-C, Python, etc.).
• Comfortable reading and understanding unfamiliar codebases.
• Debugging mindset: ability to systematically investigate issues and describe findings.
• Basic Git knowledge (clone, branch, commit, pull request).
• Conversational English (written and spoken); most code, documentation and communication is in English
• Hands-on experience with technical projects (university, personal projects, apps, web, hobby projects, Arduino, etc.)
• Required Knowledge / Tools

Required at the start:

• Git and a comfortable development environment (IDE or code editor)
• Basic command line usage
• Ability to use AI coding assistants (ChatGPT, Claude, Copilot, etc.) responsibly — understanding generated code, not just copying it

You will learn here:

• C++ in a real production codebase
• Visual Studio, Xcode, Premake and internal CI/tooling systems
• Platform-specific tooling required for SDK development

Benefits:

• Hybrid Work (2 days/week from the office);
• MyBenefits platform - meal tickets with the value of 45 Ron/day;
• Day off for your birthday, your children`s birthday and company’s anniversary. Everyone is celebrated!
• Short Friday, so you can start your Weekend at 4pm!
• Medical subscription package, in partnership with Regina Maria Clinic;
• Unique creative and professional work culture that embraces diversity;
• Supportive working climate, a team with a free communication style;

Please note that only selected candidates will be contacted and your CV will be saved in our files for a period of 6 months.
