Cover Letter – Software Engineer, macOS (Speechify)

Dear Hiring Team,

I’m excited to apply for the Software Engineer – macOS role at Speechify. With 7 years of experience building high‑performance macOS applications that serve millions of users, a deep passion for accessibility, and a proven track record of shipping polished, user‑centric features in fast‑moving, remote teams, I believe I can help Speechify continue to make reading a barrier‑free experience for everyone.

Why Speechify?

• Mission‑driven impact – Turning text into speech for 50 M+ users aligns perfectly with my belief that technology should empower every learner, regardless of ability.
• Accessibility focus – My recent work on an assistive‑reading macOS app earned the Apple Accessibility Award, reinforcing my commitment to inclusive design.
• Fast‑paced, remote culture – I thrive in distributed environments where autonomy, clear communication, and rapid iteration are the norm—exactly the setting you describe.

Relevant Experience & Achievements

Role	Highlights (macOS)
Senior Software Engineer – XYZ Corp (2021‑2024)	• Led the redesign of a macOS PDF‑viewer used by 3 M+ users, increasing launch speed by 45 % and reducing memory footprint by 30 %. • Implemented a SwiftUI‑based UI layer that co‑existed with legacy AppKit code, enabling a seamless migration path while preserving feature parity. • Built a custom concurrency framework using Combine and async/await, cutting background processing latency from 800 ms to 120 ms.
iOS/macOS Engineer – ABC Labs (2018‑2021)	• Delivered a cross‑platform (iOS/macOS) text‑to‑speech engine that integrated with VoiceOver and TalkBack, achieving 4‑star accessibility ratings on the App Store. • Designed and shipped a Bitrise‑powered CI/CD pipeline that reduced build‑time feedback loops from 30 min to under 5 min, supporting daily releases.
Software Engineer – Open‑Source Contributor (2016‑2018)	• Maintained the SwiftUI‑Toolkit library (10 k+ stars) and authored several performance‑critical components used by the community.

Key Technical Strengths

• Swift / SwiftUI – Expert‑level proficiency; comfortable mixing SwiftUI with AppKit for incremental migrations.
• macOS Frameworks – Deep knowledge of AppKit, Core Animation, AVFoundation, Accessibility APIs, and the new AppKit‑SwiftUI interop layer.
• Concurrency – Mastery of Grand Central Dispatch, Combine, and Swift’s modern async/await model; built thread‑safe data pipelines for real‑time audio processing.
• CI/CD – Hands‑on with Bitrise, GitHub Actions, and Xcode Cloud; automated UI tests with XCUITest and performance benchmarks with XCTMetric.

What I’ll Bring to Speechify

1. Product‑first engineering – I’ll partner with designers and PMs to translate user stories into elegant, performant code, always asking “How does this improve the listening experience for a user with visual or reading challenges?”
2. Scalable architecture – Leveraging SwiftUI’s declarative paradigm and a modular AppKit bridge, I’ll help future‑proof the macOS app while keeping the codebase maintainable for a growing engineering team.
3. Performance & stability – Proven ability to profile and optimize CPU, GPU, and memory usage, ensuring the app remains snappy even with large PDFs or long‑form books.
4. Accessibility advocacy – I’ll champion inclusive design patterns, conduct regular accessibility audits, and mentor the team on best practices for VoiceOver, Dynamic Type, and color‑contrast compliance.
5. Remote‑first mindset – Strong written communication, clear documentation, and a habit of delivering small, shippable increments that keep momentum high across distributed teams.
