ICONMA is a Digital Media company seeking a Sr Software Systems Engineer for their Remote location. The role involves building features and fixing bugs for a Desktop browser application while leveraging AI coding tools to maintain high-quality code and improve performance across the application.
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
- 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
