Responsibilities

IOS technical leadership: Define architecture, engineering standards, and delivery practices for a high-quality iOS codebase

Build best-in-class Swift/SwiftUI experiences: Create polished, responsive UI with strong state management, clean composition, and modular design

Performance & animation excellence: Ensure buttery-smooth interactions (scrolling, transitions, gestures), optimize render pipelines, and aggressively reduce jank, dropped frames, and memory pressure. Obsess about the animation and performance

On-device inference optimization: Implement and optimize ML inference pipelines with a focus on latency, battery, thermal limits, memory usage, and throughput

CoreML / MLX integration: Build reliable inference flows using CoreML and modern ML stacks (including MLX where appropriate), managing model formats, quantization strategies, and runtime constraints

Metal-enabled acceleration: Use Metal (and related GPU tooling) to accelerate graphics or computation where it meaningfully improves user experience and performance

Offline-first architectures: Design robust offline flows with local persistence, sync strategies, conflict resolution, and resilient background behavior

Observability & quality: Establish performance monitoring, crash/error reporting, regression testing, and release processes that keep quality high as the product scales

Cross-functional collaboration: Partner closely with product, design, and backend to translate goals into crisp technical plans and deliver reliably

Mentor and raise the bar: Coach iOS engineers through pairing, code reviews, and thoughtful guidance; drive a culture of craftsmanship and velocity

Required

6+ years of professional iOS development experience, including significant ownership of a production iOS app

Strong expertise in Swift and SwiftUI, with demonstrated ability to build complex, high-performance interfaces

Deep understanding of iOS performance: Instruments, Time Profiler, memory leaks, frame pacing, rendering costs, concurrency, and energy impact

Experience building offline-first mobile apps: persistence layers, background tasks, sync engines, and reliability under poor network conditions

Familiarity with Metal (or strong graphics/GPU optimization instincts) and when to apply it

Practical experience shipping on-device ML features using CoreML (and/or related inference runtimes), including model lifecycle and optimization considerations

Strong software engineering fundamentals: architecture patterns, testability, maintainability, and thoughtful API design

Proven leadership: driving technical direction, mentoring, and making pragmatic tradeoffs to ship

Preferred

Experience with MLX or modern on-device ML toolchains (quantization, distillation, model compression, latency tuning)

Experience building advanced animations or custom rendering (Core Animation, Metal shaders, SwiftUI performance tuning)

Experience with secure local storage, encryption at rest, and privacy-sensitive mobile features

Background in real-time systems, graphics pipelines, or compute-heavy mobile workloads

Competitive salary and performance-based incentives.

Comprehensive health, dental, and vision benefits package.
