Senior Mobile Engineer

We're looking for a Senior Mobile Engineer to help build and evolve the Android experience that millions of readers and writers rely on every day. You’ll own Android features end to end, from understanding the problem to shipping and analyzing performance.

What You’ll Do

• Own Android features end to end: Understand the problem, build it, ship it, and see how it performs in the real world.
• Shape what gets built, not just how it gets built. Push back on scope, propose simpler solutions, and raise platform constraints early.
• Write idiomatic, well-tested Kotlin and Jetpack Compose UI that fits naturally into the team’s existing architecture.
• Work directly with iOS, web, or backend engineers depending on what a feature needs, and help decide where functionality should live.
• Partner with our leadership team, design team, and engineers in the US and France to turn a rough idea into something that ships well on Android.
• Bring superb judgment to ambiguous requests. Ask good questions, spot edge cases early, and propose reasonable first steps when the full scope isn’t clear yet.
• Own shaping product and feature spaces, maintaining and driving forward momentum even when the final destination isn’t clear.
• Help raise the bar for the mobile team on code quality, testing, and product thinking.
• Attend Medium’s twice-yearly, in-person offsites (hosted in locations around the U.S.).

What You Have

• You’ve spent several years building production Android apps and are genuinely fluent in Kotlin, Jetpack Compose, coroutines, and Flow, and modern Android architecture.
• You’re an expert with all things Android engineering but can also hold your own on at least one other platform (web, iOS, or backend).
• You think like a product engineer. You don’t just build what’s asked but can own and appreciate the impact of your work at a product level. You understand the problem underneath the request, push back when something doesn’t add up, and care about whether it actually worked once it shipped.
• You’ve worked closely with designers and engineers on other platforms before. You’re good at explaining a technical tradeoff in a way that lands for non-engineers.
• You have good instincts about systems, are adaptable, and are genuinely eager to learn. You can advocate for an approach while staying open to a better one.
• You have the ability to push forward in ambiguity and make great trade-off decisions to keep a project moving.

Nice to Haves

• Experience using AI to improve a team’s leverage, reach, output, and impact.
• You’ve owned product direction yourself rather than just executing someone else’s plan.
• You personally use Medium and are genuinely excited to contribute to its mission.
