About the Role

Our team owns NewsBreak’s first-party monetization stack end to end — from the client, through the auction server, to our in-house ad platform. It’s a small team with wide surface area, which means two things: the distance between the code you write and the revenue it drives is very short, and you’ll own your area outright rather than picking up tickets from a queue.

You’ll be the person responsible for how ads load, render, and behave on iOS — in our own app, in the SDK we ship to third-party publishers, and across the external ad networks we mediate.

What You'll Do

  • Build and maintain iOS ad functionality across our app and our publisher-facing SDK
  • Own ad rendering and the ad experience: how creatives load, display, and perform, for both rich-media and native formats
  • Own viewability and event accuracy — impressions, clicks, and billing signals have to be right, and they have to reconcile with what our partners measure
  • Own the client-side mediation layer: how we request, prioritize, cache, and fall back across demand sources
  • Integrate and maintain external ad SDKs (Google, Meta, and others) through version upgrades and platform changes, and own the tradeoffs when their behavior conflicts with ours
  • Own production health for the iOS ad stack — you’re the person who responds when something breaks, including problems originating inside vendor SDKs you can’t see into. Ad code ships in our app and in our publishers’ apps, so a rendering bug is an app stability problem, not just a bad ad
  • Measure your own work — ship behind experiments and be able to show that an experience change didn’t cost revenue

What We're Looking For

  • 3+ years of production iOS development in Swift and/or Objective-C. We care more about the depth of what you’ve owned than the exact number of years.
  • You’ve owned a meaningful module end to end — design, implementation, launch, and the aftermath.
  • Experience with ad rendering standards such as MRAID or OMID — or comparable experience rendering third-party content inside a native app.
  • Strong debugging instincts. You can work backward from a crash stack and sparse logs to a root cause without a reliable local repro, and you’re comfortable investigating systems you don’t have the source for.
  • Judgment about AI tools. You use AI coding assistants as part of your normal workflow, and you can articulate where they help you and where you override them.
  • Comfort with numbers. You’ve shipped behind experiments before and can reason about a metric moving without needing someone to interpret it for you.
  • Ownership. On a team this size, work isn’t handed to you pre-scoped — you spot problems, define them, and drive them to done. And you treat “it shipped” as the start of your responsibility, not the end.
  • Clear communicator who’s comfortable working directly with product, QA, and other non-engineers.

Nice to Have

  • Mediation or in-app bidding experience
  • SDK development experience — public API design, backward compatibility, dependency discipline
  • Background in feed, video, or other latency-sensitive surfaces
  • Familiarity with mobile privacy and consent frameworks

How We Work

We use AI coding tools as part of our normal workflow, and we expect you to. To be clear about what that means: we use them to take the tedium out of the job, not to compress three people’s work into one.

It’s also worth being honest about where they help. A lot of this role — debugging vendor SDKs you have no source for, chasing rendering issues across the native/web boundary, working out what a metric movement actually means — is work the tools are still bad at. That’s the part we’re hiring for. If you enjoy the debugging more than the typing, you’ll like it here.

You’re welcome to use AI tools throughout our interview process, including the hands-on session. The only expectation is that you can explain and defend whatever you submit.

The US base salary range for this full-time position is listed below. Pay may vary based on a number of factors including job-related skills, level, experience, geographic location and relevant education or training. At NewsBreak, we design our overall rewards package to attract top talents. Depending on the position, the role may also be eligible for discretionary bonus and options. Your recruiter can share more details during the hiring process.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
