Job description

SpaceXSI is building Super Intelligence to help humanity understand the universe. Its teams are developing the full Super Intelligence stack, bringing together Colossus supercomputers, Grok models, and a suite of applications that includes Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. The company is creating a connected development cycle in which more compute helps train better models, better models enable more useful products, and insights from people using those products inform what the teams build next. SpaceXSI’s work is guided by the belief that a future in which humanity explores the stars is more exciting than one in which it does not, and by the ambition to help make life multiplanetary and expand consciousness to the stars.

About The Role

SpaceXSI is seeking an exceptional Android Engineer to join a small, high-impact team working to create an AI application that delivers meaningful value to users. In this role, you will help shape cutting-edge mobile experiences by combining strong Android engineering skills with thoughtful product judgment and a high standard of craft. You will work on the most important product or technical challenge for the team at any given time, contributing across the application as priorities evolve. You will help build and improve features that make advanced AI capabilities useful, intuitive, and engaging on Android. Success requires more than implementing specifications: you will use your product sense to identify opportunities, make sound technical decisions, and deliver experiences that feel polished and reliable. As part of a small team, you will have meaningful ownership, collaborate closely with teammates, and take responsibility for substantial areas of the product and its underlying implementation.

Qualifications

Candidates should be proficient in Kotlin, Jetpack Compose, and reactive programming, with experience architecting modern, large-scale production applications. You should demonstrate technical excellence and the ability to create intuitive, delightful user experiences. Strong ownership and agency are important, as the role calls for someone who can adapt, take on multiple responsibilities, and make progress on complex challenges with appropriate independence. You should also be able to optimize Android applications for performance, stability, and reliability. Preferred experience includes a track record of shipping standout applications or features that demonstrate both technical quality and exceptional product intuition. Deep familiarity with the Android ecosystem and tools such as Android Studio and Gradle is valued. Experience with Rust for working with backend components is also beneficial.

Responsibilities

Design, develop, and maintain high-quality Android experiences using Kotlin and Jetpack Compose. Build product features that make AI capabilities accessible and useful, and contribute to the architecture of a modern production application. Apply reactive programming practices where appropriate, and make engineering decisions that support maintainability, performance, stability, and reliability. Partner with a focused, high-impact team to identify and address the most critical product or technical needs. Take ownership of significant areas of work, from understanding user and product goals through implementation and refinement. Bring strong attention to detail to interactions and visual polish, and use product judgment to help ensure that the application is intuitive and valuable. Where relevant, contribute to integration with backend components, including work involving Rust.

Benefits

The stated salary range is $180,000–$440,000 USD. Base salary is one part of SpaceXSI’s total rewards package, which also includes equity, comprehensive medical, vision, and dental coverage, short- and long-term disability insurance, life insurance, and various other discounts and perks.
