Who we are:

Chartboost is the leading in-app monetization and programmatic advertising platform.

Chartboost is hiring a Senior iOS Engineer to help us build and maintain our newest SDK product.

The Helium SDK is a mobile advertising SDK that combines traditional waterfall impression placement and programmatic real-time bidding. Real-time bidding is a new technology in the mobile advertising industry, and Helium brings that new technology to 1,000’s of game developers.

Helium is a new product and we have an exciting roadmap ahead. This role will help shape that roadmap and ensure its timely implementation.

  • Develop and maintain internal apps used for debugging and testing purposes
  • Apply and promote iOS development best practices in order to keep a high-quality development process in our SDK
  • Create and enhance integrations with new and existing partners, such as Ad Mob and Facebook.
  • Enhance your understanding of low-level implementations whilst working on UI utility apps with the latest technologies
  • Work closely with QA team members in order to establish procedures that will keep our SDK stable
  • Carefully balance performance, memory, and network usage, respecting users, app developers, and our network
  • Keeping up to date with iOS technologies as well as maintaining and evolving an Objective-C codebase to a modern Swift environment
  • Timely communication with Product and Business to ensure priorities are always aligned with company goals

Who you are: 

  • You have 5+ years of professional iOS software development experience
  • A quality-oriented professional with strong unit test skills 
  • Highly proficient in iOS development using Objective C, Swift, the latest iOS development tools, and XCTest for testing.
  • You have shipped iOS apps and/or iOS SDKs/Frameworks with a server component

The following experience would be a plus: 

  • Ad Tech
  • Built and shipped SDKs or libraries
  • Debugging proxies (Charles Proxy, preferred)
  • Unity 3D game or plugin development
  • Migrated Objective C code to Swift
  • CocoaPods build process and creating Pods


  • The opportunity to help continue to build a company with the founding team
  • Restricted Stock Units (RSUs) - you will have a stake in the future success of Chartboost and Zynga
  • Comprehensive medical, dental and vision insurance 
  • 401(k) plan with match through Fidelity
  • Catered lunches and fully stocked kitchens 
  • Commuter Program
  • Flex Vacation – personal time to refresh your mind/body/soul, spend time with loved ones and celebrate life events. There is no accrual or specific limit to the amount of time an employee may use
