Job Title: Senior iOS Engineer

Company Name: Sully.ai

Job Url: https://careers.kula.ai/sully/25360

Job Description: Key Responsibilities
Own end-to-end engineering execution for iOS, from architecture and roadmap through delivery and reliability.

Drive step-function performance improvements, targeting at least 50% reductions in app launch time, memory usage, and crash rates.

Design and operate robust observability, metrics, and automated testing systems to ensure consistent performance at scale.

Lead iOS execution rituals including daily and weekly standups, backlog ownership in Linear, and tight cross-functional coordination with Product, Design, and Backend teams.

Translate product goals into clear dependencies, timelines, and deliverables to keep teams unblocked and shipping.

Drive mobile EHR integration excellence, ensuring seamless integration with Epic Haiku, Epic HyperSpace, and other mobile EHR platforms.

Hard Requirements
Founder-level ownership mindset. You operate like the business depends on your decisions and execution.

Senior, hands-on iOS engineering ability. You actively design systems, write and review production Swift code, and set the technical bar by example.

Deep iOS platform expertise. 7+ years of iOS development with Swift/SwiftUI, UIKit, and modern iOS architectures. Experience shipping consumer-grade iOS apps to the App Store at scale.

Experience in high-intensity environments such as YC-backed startups, early-stage companies, or zero-to-one teams where speed and judgment matter.

Mobile leadership experience. You've led iOS teams (3+ engineers) and own mobile engineering processes, release management, and cross-platform coordination.

Comfort with ambiguity. You turn incomplete product direction into clear technical plans and ship without heavy process.

Bias toward leverage and simplicity. You choose durable solutions and know when to optimize versus when to ship.

Key Results (First 90 Days)
Take full ownership of iOS engineering. Establish yourself as the DRI for all iOS architecture, quality, and delivery decisions.

Ensure end-to-end observability and alerting for core iOS workflows including note generation, medical assistant features, and EHR sync.

Define key performance, reliability, and quality metrics for the iOS app (crash-free rate, memory usage, app launch time, user satisfaction scores).

Identify and ship at least one high-impact improvement — whether performance optimization, memory leak fix, or critical user experience enhancement.

Establish execution cadence, priorities, and quality standards including iOS release process, QA workflows, and automated testing infrastructure.

Audit and improve iOS technical debt including architecture issues, memory leaks (IOS-307), and automation testing setup (E-6337).
