Sr Software Systems Engineer (Desktop AI app)

Our Client, a Digital Media company, is looking for a Sr Software Systems Engineer (Desktop AI app) for their Remote(EST city)  location.
 
Responsibilities:

• Build features, fix bugs, and ship product on the Desktop browser application (macOS/Windows), which is built on top of Chromium.
• Use AI coding tools (Claude Code, Codex) to write and maintain high-quality, efficient code our team does not write code by hand.
• Work across layers of the Desktop app from UI components and browser chrome to backend service integrations using AI tools to ramp quickly on unfamiliar areas.
• Debug and resolve issues related to rendering, networking, and system integration on desktop platforms.
• Participate in code reviews as applicable, weekly meetings, daily standups, and weekly demos (Fridays).
• Occasionally work across platform boundaries when needed (e.g., touching backend services or shared code used by other platforms).
• Desktop browser feature development: AI-driven features, custom browser UI, and service integrations
• Performance, stability, and quality improvements across the Desktop app
• Developer tooling, CI/CD, and build system improvements as needed
• Feature velocity — shipping user-facing desktop features within our 1-week cycle cadence
• Effective use of AI coding tools leveraging agents for implementation, managing multiple agent sessions, and maintaining quality through review

 
Requirements:

• Ability to ramp quickly on unfamiliar parts of the codebase using AI tools to bridge knowledge gaps
• Quality — PRs pass CI, don't regress existing features, and follow established convention
• PRs shipped per week
• Stability metrics crash rates, bug count, CI pass rate on desktop builds
• Peer feedback and ability to unblock other engineers
• 6+ years of professional software engineering experience
• Strong proficiency in at least one systems or application programming language (e.g., Swift, C++, Rust, C#, or similar) — the Desktop app uses Swift (macOS) and C++ but AI tools help bridge language gaps
• Experience building and shipping complex desktop applications on macOS and/or Windows
• Strong problem-solving skills and comfort navigating large, unfamiliar codebases
• Willingness and ability to use AI coding tools (Claude Code) as the primary development method — this is non-negotiable
• Ideal experience level (years, leadership, industries):
• 6-10+ years of software engineering with a track record of shipping consumer desktop products
• Prior experience with large-scale desktop apps (browsers, IDEs, media apps, productivity tools, or similar)
• No management or leadership requirement  this is a hands-on IC role

 
Why Should You Apply?

• Health Benefits
• Referral Program
• Excellent growth and advancement opportunities
