Junior Full-Stack Engineer: Master Debugging & Payments

SOUND DECISIONS; Illinois; Presencial; USD 60.000 - 90.000; Jornada completa

Descripción de la vacante

SOUND DECISIONS is seeking a junior software engineer to dive into how systems operate, not just how to compile. You’ll learn in a small senior team with real production scope, mentored to become exceptional.

Formación

• Working knowledge of software development fundamentals: data structures, complexity, state, and how a request moves from a browser to a database and back.
• Experience with, or demonstrated ability to learn, TypeScript and full-stack web development.
• Familiarity with Git and the core concepts of pull requests, merging, branching and code review.
• A decent level of maturity with AI coding tools: you have used them on personal or open source projects, you have been burned by them at least once, and you can describe what you check before you trust the output.
• The ability to work independently on defined tasks while asking for help when appropriate, and the judgment to tell the difference.
• Comparable experience counts. Building backend or full-stack applications with Node.js and TypeScript is directly relevant; Scala and functional programming are valuable but not required.

Responsabilidades

• Develop how to understand priorities: know which ticket matters this week and why.
• Learn to provide solutions, not just problems: arrive with what you tried, what you found, and what you think.
• Learn to anticipate needs: if a change touches the portal, you already checked who consumes it.
• Build credibility: small promises kept, every time.
