Job summary

LineLeap in the United States is seeking a senior software engineer to own large-scale features for a high-traffic consumer platform. You will ship from concept to production, diagnose production issues, and influence product and technical direction with autonomy.

You will work on both frontend and backend in a modern stack (Flutter, TypeScript, Node.js, GCP) and thrive in a fast-paced, high-ownership environment with strong emphasis on reliability and scale.

Qualifications

• 4+ years of experience writing high-quality production code.
• 2+ years of on-call experience for critical production services.
• Demonstrated ability to work independently and own large pieces of work.
• Experience building or scaling high-traffic services where uptime matters.

Responsibilities

• Build and ship high-impact product features from idea to production and launch.
• Solve hard scaling and reliability problems as traffic grows.
• Shape product direction with the team, turning goals into plans.
