Staff Android Engineer – Kotlin

Role Overview

• Own the architectural direction of Saily for Android, spot existing and future bottlenecks in the codebase, build pipeline, and development workflow before they slow the team down.
• Drive decisions on modularization, dependency management and platform-level patterns (navigation, DI, networking, etc.) that keep the codebase scalable as the team and product grow.
• Continuously identify, prioritize and plan reduction of technical debt. Make the cost of inaction visible to Product Owners so it gets scheduled, not just acknowledged.
• Champion app startup time, animation smoothness, memory/battery usage and crash-free rates. Establish performance budgets and automated guardrails.
• Elevate testing practices (unit, integration, UI), prioritize security and work with QA Team to ensure Saily consistently meets a high quality standard.
• Coordinate with all the necessary teams to align on priorities, unblock delivery and ensure mobile needs are represented in platform-wide decisions.
• Hands-on contribution to Saily Android development: building features, interacting with backend REST APIs (providing feedback based on mobile-specific needs) and collaborating with Web, Backend, and UX teams to ship new functionality and raise the bar on existing features.
• Debug and resolve issues surfaced by users, internal testing, and production monitoring.
• Mentor Android engineers and help QA Team through code reviews, pairing, architecture discussions and knowledge-sharing; help individuals grow technically without formal management authority.
• Champion AI usage across the Android platform and beyond. Evaluate and integrate AI tooling into the Android development workflow. Prepare devtools, project structure and documentation for effective agentic coding.
• Evaluate cutting-edge tools, libraries, and Android platform changes. Recommend adoption of new tools when the ROI is clear.

Requirements

• 5+ years of professional Android development experience, with deep expertise in Kotlin, modern Android architecture (Compose, coroutines, multi-module projects) and the Android platform internals.
• Proven records of driving architecture decisions, leading large cross-cutting initiatives and raising quality across a team or organization without relying on positional authority.
• Proven ability to identify systemic issues (build times, flaky tests, architectural coupling, slow release cycles) and drive pragmatic solutions.
• Ability to translate technical complexity for non-technical and cross-platform stakeholders (POs, designers, backend, web) and build alignment around technical direction.
• Actively unblock others, break down complex problems, foster collaborative relationships across teams and platforms and use failure as a blameless learning opportunity.
• Proficiency with CI/CD pipelines, release automation, and mobile-specific observability/monitoring.
