Staff Engineer Jobs in San Francisco, CA

About the OpenClaw Foundation

The OpenClaw Foundation is the steward of the world's largest open-source AI agent project. Our mission is grounded in a foundational conviction: AI should be open, safe, and ultimately owned by the individuals and communities who use it.

The Foundation operates across three core mandates:

• Advancing research into the human-agent relationship while continuously evolving the OpenClaw platform.

• Ensuring the security, reliability, and long-term sustainability of the OpenClaw codebase.

• Establishing open standards for agent configuration, communication, trust, transactions, and user identity.

Inspired by organizations like the Linux Foundation and W3C, we are building a neutral, multi-stakeholder ecosystem that enables individuals and organizations to participate in the future of open-source AI.

About the Role

OpenClaw Foundation is looking for our first Mobile Engineer (Member of Technical Staff) to help build and evolve the mobile experience for OpenClaw from the ground up (0-1).

As the sole mobile developer, you'll work on the applications and infrastructure that bring personal AI agents directly into users' everyday lives. This includes building intuitive, high-performance mobile experiences that allow users to interact with, configure, manage, and communicate with their agents from anywhere.

This is a hands-on engineering role for someone with demonstrated experience building and shipping applications across both iOS and Android. You'll be responsible for delivering polished, reliable mobile experiences while navigating the unique technical requirements of each platform.

You'll work closely with product, design, and platform engineering to translate complex agent capabilities into simple, accessible mobile experiences. The ideal candidate is comfortable operating in a fast-moving, open-source environment, takes ownership of features from concept through production, and enjoys working across the full mobile stack.

What You'll Do

1. Mobile Product Development

• Build, ship, and maintain high-quality mobile applications across both iOS and Android.

• Develop core experiences that allow users to interact with, manage, configure, and communicate with their AI agents directly from their mobile devices.

• Translate complex agent capabilities into intuitive, accessible, and performant mobile interfaces.

• Own features end-to-end, from technical design and implementation through testing, release, and iteration.

• Build and optimize real-time interactions, messaging, notifications, and agent communication experiences.

• Ensure consistent functionality and a polished user experience across different devices, screen sizes, and operating system versions.

2. Mobile Architecture & Infrastructure

• Contribute to the architecture and technical direction of OpenClaw's mobile applications.

• Build scalable, maintainable mobile infrastructure that supports an evolving ecosystem of agents, tools, and integrations.

• Integrate mobile applications with OpenClaw's backend services, APIs, and agent communication protocols.

• Develop reliable approaches to background processing, state management, synchronization, and offline functionality.

• Work with cross-platform frameworks and native iOS and Android capabilities to deliver consistent experiences without compromising platform-specific functionality.

• Ensure applications perform reliably across different devices, operating systems, and network conditions.

3. Performance, Security & Reliability

• Optimize application performance, responsiveness, battery consumption, memory usage, and network efficiency.

• Implement secure authentication, session management, permissions, and data handling.

• Account for the unique security and privacy considerations of AI agents accessing user data, local devices, and external systems.

• Build robust error handling, monitoring, logging, and debugging capabilities.

• Identify and resolve technical issues across the mobile stack and both operating systems.

• Establish testing and quality standards to ensure reliable releases across iOS and Android.

4. Cross-Functional & Open-Source Collaboration

• Work closely with product designers, platform engineers, and the broader OpenClaw community to deliver cohesive product experiences.

• Partner with design to translate product vision into polished, production-ready mobile experiences.

• Collaborate with backend and platform engineers to integrate new agent capabilities into the mobile experience.

• Contribute to technical decisions, code reviews, documentation, and engineering standards.

• Participate in open-source development, contributing improvements and engaging with developers across the ecosystem.

• Help identify opportunities to improve the overall developer and end-user experience.

What We're Looking For

• 6+ years of professional experience building and shipping production mobile applications.

• Demonstrated experience developing for both iOS and Android, with a strong understanding of each platform's architecture, capabilities, and development requirements.

• Experience with native development using Swift (iOS) and Kotlin (Android).

• Experience shipping and maintaining applications across both the Apple App Store and Google Play Store.

• Strong understanding of mobile architecture, state management, API integrations, and asynchronous programming.

• Experience working with REST APIs, WebSockets, real-time communication, and backend services.

• Strong understanding of mobile performance optimization, debugging, testing, and release management.

• Experience with authentication, secure data storage, permissions, and mobile application security.

• Ability to deliver consistent, high-quality experiences across both platforms while accounting for native functionality and usability.

• Ability to own features independently, make sound technical decisions, and deliver high-quality code.

• Strong product instincts and an appreciation for the details that make mobile experiences feel intuitive and polished.

• Comfortable working in a fast-moving environment with evolving requirements and a high degree of ownership.

Nice to Have

• Experience building AI-powered applications, AI assistants, or agentic products.

• Familiarity with LLM integrations, streaming responses, tool calling, and real-time agent interactions.

• Experience with background tasks, push notifications, deep linking, and mobile-to-device communication.

• Experience with native iOS and Android capabilities beyond cross-platform development.

• Experience with open-source projects and community-driven development.

• Familiarity with Linux, self-hosted infrastructure, or developer tooling.

• Experience building applications that interact with local devices, APIs, and external services.

• Experience optimizing applications for different network conditions, offline usage, and background execution.
