Summary: Robots & Pencils is seeking a Senior Android Developer to lead the development of an agentic AI co-pilot for commercial truck drivers, focusing on robust mobile solutions in challenging environments. Highlights: 1. Lead complex Android features end-to-end for an AI co-pilot platform 2. Architect robust voice interaction flows and optimize speech AI for mobile 3. Influence architecture and mentor engineers in a real-world, high-impact role Robots \& Pencils is seeking a Senior Android Developer to lead the development of a voice\-enabled, on\-device agentic AI co\-pilot for commercial truck drivers. The platform runs on fleet\-issued Android tablets and proactively diagnoses device, connectivity, and application issues while assisting drivers with scheduling, compliance, and troubleshooting, even in low\-connectivity environments. This is a hands\-on senior engineering role. You will own complex Android features end\-to\-end, contribute to architectural decisions, and ensure the reliability, performance, and scalability of mobile systems operating under real\-world constraints. You will collaborate closely with AI engineers, product managers, designers, and backend teams to deliver resilient, production\-grade mobile solutions. As a Level 4 developer, you are expected to lead implementation efforts, influence technical direction, proactively identify risks, and uphold high standards for maintainability, performance, and operational excellence. **Key Responsibilities** **Android Application Development** * Own the design and implementation of complex Android features for fleet\-managed tablets * Architect and implement scalable UI and background functionality aligned to established patterns and evolving system needs * Design and maintain offline\-first behaviors that ensure seamless operation in low\-connectivity environments * Integrate Android applications with on\-device AI components and system\-level services * Lead performance optimization, stability improvements, and technical debt reduction initiatives * Establish and uphold testing strategies to ensure reliability across diverse field conditions **AI \& Voice Feature Leadership** * Lead integration of Android components with agent\-based AI systems * Architect robust voice interaction flows including push\-to\-talk and guided troubleshooting * Integrate and optimize speech\-to\-text and text\-to\-speech services for mobile execution * Ensure AI\-driven workflows are predictable, user\-safe, and operationally resilient **Device \& Connectivity Architecture** * Design solutions leveraging Android APIs to monitor connectivity state and device health * Architect diagnostic workflows across application, OS, and network layers * Lead root\-cause analysis efforts for complex production issues affecting performance or reliability **Integrations \& Backend Collaboration** * Own Android\-side integrations with REST APIs, including Motive ELD / HOS systems * Define and validate integration contracts in collaboration with backend and AI teams * Contribute to API design discussions to ensure mobile scalability and resilience * Lead code reviews and promote high engineering standards within the team **Technical Leadership \& Delivery** * Drive technical planning, estimation, and delivery of mobile initiatives * Proactively identify architectural risks and propose mitigation strategies * Mentor Level 2–3 engineers through code reviews and technical guidance * Contribute to documentation, shared standards, and mobile best practices * Communicate progress, risks, and tradeoffs clearly to cross\-functional stakeholders **Required Skills \& Qualifications** * **5\+ years of experience** developing production Android applications * Strong expertise in Kotlin and modern Android development practices * Deep knowledge of Android lifecycle management, permissions, and background execution * Expertise in architecting offline\-first mobile solutions, ensuring reliable data persistence and background synchronization across varying or limited network conditions * Strong experience integrating REST APIs and managing mobile\-network interactions * Proven ability to debug complex issues across application, OS, and network layers * Experience optimizing performance for device\-constrained environments * Upper\-intermediate English (written and spoken) **Technology Environment** **Mobile:** Android **AI / Agent Systems:** Agent runtimes, planning \& tool\-execution workflows **Voice AI:** Speech\-to\-text, text\-to\-speech, push\-to\-talk interaction **Systems:** Connectivity monitoring, device state, MDM\-managed environments **Integrations:** REST APIs (Motive ELD / HOS), support and messaging platforms **Nice to Have** * Exposure to on\-device or edge\-constrained computing environments * Experience with voice\-enabled or conversational mobile applications * Familiarity with MDM\-managed or enterprise Android deployments * Familiarity with AWS AI and agentic services supporting intelligent system workflows **Personal Competencies** * **Technical Ownership** – Leads complex features from design through production * **Engineering Pragmatism** – Designs solutions aligned to device and OS constraints * **Architectural Thinking** – Makes sound design decisions under real\-world tradeoffs * **Collaborative Leadership** – Elevates team quality through mentorship and review * **Product Awareness** – Balances user needs with operational reliability * **Accountability** – Owns outcomes, not just implementation **Why Join Robots \& Pencils?** We build systems that operate in the real world, not ideal conditions. As a Level 4 Android Developer, you will play a key role in shaping a highly visible platform that blends mobile engineering with applied AI under tight constraints. You'll influence architecture, mentor peers, and deliver production\-grade systems that support real users in complex operational environments. This is a role for experienced builders who want to lead technically, solve meaningful problems, and operate at the intersection of mobile systems and intelligent software.
