Full job description

SpaceXAI's mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company's mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

ABOUT THE ROLE:

We're seeking an exceptional iOS engineer to join a small, high-impact team dedicated to creating the world's most valuable AI application, judged by the impact it delivers to users. You'll shape cutting-edge mobile experiences, blending technical mastery with product brilliance.

RESPONSIBILITIES:

Dream up and craft delightful, intuitive user experiences that redefine how people interact with AI on mobile.
Obsess over every pixel, animation, and interaction, ensuring the experience feels magical and seamless.
Build blazing-fast, highly performant systems where every millisecond counts.
Drive technical and product decisions, collaborating with AI researchers and engineers to deploy state-of-the-art models globally.

BASIC QUALIFICATIONS:

Expert in Swift, with deep knowledge of SwiftUI and UIKit.
Proficient in performance optimization—memory, CPU, GPU—using low-level tools to deliver blazing-fast systems.
Experienced in designing and shipping intuitive, pixel-perfect mobile UIs that redefine how users interact with AI.
Skilled in concurrency and reactive programming (Combine) for responsive, real-time apps.
Built high-throughput integrations with APIs (REST, gRPC) or AI model outputs, ensuring seamless data flow.
Capable of owning complex features end-to-end, from architecture to App Store deployment, with a focus on speed and scalability.

PREFERRED SKILLS AND EXPERIENCE:

Deep expertise in the Apple ecosystem and related development tools.
Rust for working with our backend components.
AVFoundation for real-time audio processing.
Track record of shipping standout apps or standout features within apps.
Deep expertise in iOS development, particularly with Swift. We seek individuals who operate at the highest levels of their craft.
Excel at delivering results swiftly, often in a fraction of the time others require. Speed is a core value at SpaceXAI—we must act decisively to succeed.
Sharp product sense, with an ability to empathize with users, anticipate their needs, and translate that into features that delight and deliver value.

COMPENSATION AND BENEFITS:

£107,000 - £262,000 GBP

Base salary is just one part of our total rewards package at SpaceXAI, which also includes equity, comprehensive healthcare and dental coverage, cash plan, income protection, life insurance, and various other discounts and perks.
