Android Engineer

Android Engineer

This is an extraordinary moment to join us. We're in the middle of a fundamental agentic shift in software development, and are embracing the change. We're operating in an agentic-first world, where the role of a builder is shifting from writing every line of code to designing systems that build, test, and improve themselves.

At Speak, you'll use AI agents as core collaborators in your day-to-day workflow—helping you move faster, explore more ideas, and focus on the highest-impact problems. That means embracing ambiguity, iterating quickly, and working fluidly across functions—not just within a single discipline.

We're looking for an Android Engineer who is excited to rethink how work gets done in an AI-native environment, and who want to help define what building looks like in this new paradigm.

As an Android Engineer on Speak's engineering team, you will be responsible for a variety of features including improving how we serve our content, run A/B tests on monetization features, support launching of new markets and new languages. You will collaborate closely with backend engineers and our partners in Product and Design. You'll be responsible for shipping product features to millions of users.

What you'll be doing:

• Build growth loops -> referrals, in-app shareables, Speak on web
• Improve new user acquisition and user retention
• Pricing and packaging
• Launch new markets and languages
• Improving our text to speech system
• Improving our audio and video streaming systems

What we're looking for:

• 3+ years of industry experience working as a Mobile Engineer, preferably in a fast-paced startup environment
• Proficiency in Kotlin, with a strong understanding of common mobile architectures including MVC/MVVM
• Experience using coding agents (e.g. Claude Code, Codex, Cursor) as core collaborators in your day-to-day workflow — not just as autocomplete, but as active partners in designing, testing, and shipping.
• Reactive programming(RX Java, etc)
• Knowledgable in mobile build practices(eg jenkins, bitrise)
• Knowledgable in Google Play Billing
• Excellent problem-solving and communication skills, and the ability to work independently or as part of a team
• Coach and mentor other engineers
• Strong product sense: ability to think broadly/cross-functionally about product experiences

Office: San Francisco, CA

Why work at Speak:

1. Join a fantastic, tight-knit team at the right time: we're growing very quickly, we've most recently raised our Series C from some of the top investors in the valley, and we've achieved product-market fit in our initial markets. You'd join at a magical time when a single person could significantly change the course of the company.
2. Do your life's work with people you'll love working with: we care strongly about our craft and want every person at Speak to feel like they're growing every day. We believe in the idea that working with people you both enjoy and have respect for makes everything better. We hire thoughtfully and only work with people we admire deeply.
3. Global in nature: We're live in over 40 countries and launching in a number of new markets soon. We have dedicated offices in San Francisco, Ljubljana, Seoul, and Tokyo, and you'll have the opportunity to talk to users in each of these regions on a regular basis as well as travel.
4. Impact people's lives in a major way: Learning a language is one of the single most life-changing skills one can learn, and right now 99% of people never achieve their goal because the process is broken. We're helping millions of people achieve their goals and improve their lives.
