Senior Mobile Engineer

Ground News is a platform that makes it easy to compare news sources, read between the lines of media bias and break free from algorithms.

In a world where political polarization and media distrust are at an all-time high, Ground News offers people a better way to stay informed and see every side of the story. Our mobile app, web app, and browser extension are home to a community of mindful readers who use our news comparison platform to engage with news beyond their filter bubble.

Unlike most news companies, our values do not align with any specific political ideology. Unlike most tech platforms, we don't rely on algorithms to keep users on our platform to sell more ads. We are supported by our readers who pay for a subscription to build a more nuanced understanding of the news, the world, and themselves.

As a senior mobile engineer, you’ll share the technical direction of our Android app, which turns curious visitors into engaged, paying readers. This is a senior individual contributor role for someone with a strong, data-informed track record of growing both the user base and revenue from mobile. You'll sit within our mobile chapter and work day-to-day out of the Growth & Monetization pod, partnering closely with Growth, Marketing, the Sponsor ships team, and our Conversion Rate Optimization (CRO) function.

Reporting to the Growth & Monetization App Lead, you'll set the bar for how we build, measure, and experiment on the Android.

Our stack includes Kotlin, Jetpack Compose, MVVM, Firebase and Revenue Cat. You'll bring deep fluency in modern mobile engineering together with a growth mindset: you think in funnels, experiments, and conversion, and you have informed views on what moves the numbers on a consumer mobile property.

A defining goal of this role is to make our CRO, Marketing, and Sponsor ships partners self-sufficient. Within your first 90-180 days, success looks like a marketing or growth teammate being able to ship a landing-page change, a modal, or a pricing experiment without an engineer in the loop. You'll evaluate and mature tooling: visual page and landing-page builders, experimentation platforms, analytics and CDP integrations.

This is a high-leverage role. You'll operate as the senior technical voice for mobile: shaping architecture, raising code quality, and steering the experimentation roadmap that compounds growth over time.

• Share the technical strategy for Ground News' mobile properties, with a direct mandate to grow the user base and subscription revenue from Android.

• Build and ship high-quality Kotlin experiences across our Android app's many conversion surfaces.

• Partner with the CRO, Growth, Marketing, and Sponsor ships functions to translate hypotheses into experiments, making those partners self-sufficient so they can change subscription pages, modals, and copy without engineering in the loop.

• Own and evolve the marketing-tech stack: today our subscriptions work heavily with Revenue Cat and Google Play directly, alongside A/B testing and experimentation platforms and analytics / CDP tooling—you'll lead that evolution and design the guardrails that keep it safe and performant.

• Mature and add rigour to our mobile experimentation program: framing hypotheses, sizing impact, ensuring clean measurement, and shipping winners while reading results honestly.

• Set the bar for mobile performance, accessibility, analytics, and Core Mobile Vitals on a consumer property serving millions of readers.

• Act as the senior voice in code review and architecture for the mobile chapter, expediting the PR process and raising overall engineering quality.

• Manage safe rollouts of the Android app: feature flagging, monitoring conversion…
