Unity SDK Developer

VYBS is a mobile gaming loyalty and CPI marketplace: players discover games in the VYBS app, hit in-game milestones and earn rewards, while advertisers get measurable, high-intent installs.

The role. Game studios come to us today as advertisers, buying installs. The Unity SDK opens the other direction: a studio embeds a VYBS placement in their game, players who tap it land in the VYBS app, and the studio gets paid for them. It's a new revenue line, competing for a slot against rewarded video and offerwalls, and judged on the same terms — revenue per DAU.

You'll be the first dedicated engineer on the SDK, owning architecture, public API, releases and the partner experience end to end.

What you'll do

• Design and build the SDK: in-game placement components, app-to-app handoff, deep linking, and the referral identifier that survives the store visit and install.
• Build the native layer: iOS and Android bridges, IL2CPP, Gradle and Xcode plugin plumbing, coexistence with the other SDKs in the build.
• Hold size, cold-start and frame-time budgets, enforced in CI.
• Own versioning, UPM/Asset Store distribution, Unity LTS support, and migration paths.
• Build the test surface: sample game, cross-version build verification, integration tests, debug mode, and the docs.

What we're looking for

• 5+ years engineering, substantial Unity/C# shipped to iOS and Android.
• You've built or core-contributed to a library or SDK other developers consume, with opinions on API design and backward compatibility.
• Deep knowledge of the Unity mobile build pipeline.
• Comfortable below C# in Kotlin/Java and Swift/Obj-C to build bridges and debug platform behaviour.
• Profiling discipline, and strong written English.
• Nice to have: a monetization SDK — offerwall, rewarded video, mediation — or attribution and deep-linking at an MMP; mobile game development or live-ops; reward-fraud work.
