Android Software Engineer
Bjak
Bjak is building AI-native applications for everyday tasks like email, notes, and workflows. As an Android Software Engineer, you'll own how users experience AI on mobile—this is a core product role, not a thin client job. You'll ship real production code that matters.
Your day-to-day: build and maintain Android apps in Kotlin, integrate AI features (chat, vision, voice, recommendations) through backend APIs, and design UX patterns that handle streaming responses, retries, and reliability. The focus is on making workflows fast and dependable on actual mobile devices.
This fits you if you have Android fundamentals, comfort with Kotlin, and genuine interest in how AI interacts with users. A portfolio of shipped work or side projects helps. You don't need years of experience—you need solid engineering basics and the drive to build something users rely on daily.

About this role
About A1 There are over 5 billion users using basic applications today such email, notes, tasks that are not AI-native. Our mission is to build a proactive smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows, with minimal prompting. Our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. Our objective is to help users complete tasks daily enjoyable with over ~90%* reduced time. Role As an Android Software Engineer, you own the Android client experience, how AI feels, behaves, and performs on mobile devices. This is not a thin client role. You will build a production Android application where AI interactions are core to the product, and performance, reliability, and clarity matter. Focus Build and maintain production Android apps using Kotlin. Integrate AI-powered features (chat, vision, voice, recommendations) via backend APIs. Design UX patterns for AI interactions, including streaming responses, retries, and partial results. Optimize performance, memory usage, and responsiveness for AI-heavy flows. Implement analytics, logging, and feedback capture to support AI evaluation and iteration. Collaborate closely with backend and ML engineers on API contracts and system behavior. Ensure app stability, security, and scalability in production environments. Ideal Experiences 3+ years of Android development experience using Kotlin. Hands-on experience integrating AI features (e.g. LLM, vision, speech APIs). Strong understanding of asynchronous programming (Coroutines, Flow). Familiarity with REST or gRPC APIs and structured data formats. Strong debugging and performance profiling skills. Comfort building in environments with latency, partial failure, and non-deterministic behavior. Experience with MLKit or light on-device inference. Published production apps on the Google Play Store. Outcomes Stable, smooth, and reliable real-world use android applications. Performance is optimized: responsive, low-latency, and efficient on memory and CPU. Production issues are detected early, monitored effectively, and resolved with clear root-cause analysis. Tech Stack Kotlin / Java SQL / noSQL TensorFlow Lite (on-device inference) How We Work The best products today in the world were built by small, world class teams. We are a high talent density and hands-on team. We make decisions collectively, move at rapid speed, striking a balance between shipping high quality work and learning. Joining our team requires the ability to bring structure, exercise judgment, and execute independently. Our goal is to put in hands of our users a truly magical product Interview process If there appears to be a fit, we'll reach to schedule 3, but no more than 4 interviews.
