• Write maintainable and well-documented code without reliance on AI-generated boilerplate.

The company values technical depth and expects candidates to critically evaluate their preliminary code before applying.

Screening Process

POS+ utilizes a unique, collaborative recruiting process that involves:

• An Initial Intro & System Design session lasting about 45 minutes where candidates discuss their experience, technical strategies, and general system architecture decisions.
• A Live Code Review & Debugging Session for about 60 minutes, where candidates will audit a poorly structured JavaScript/TypeScript codebase and suggest improvements live, showcasing their ability to identify issues and refactor code efficiently.

Key Responsibilities

The role includes the following core responsibilities:

• Develop and maintain scalable full-stack features using Node.js, React, and TypeScript.
• Optimize database queries and create efficient schema designs to manage high transaction volumes.
• Ensure the security and scaling of APIs for rapid synchronization in varying software environments.
• Proactively seek and eliminate technical debt, adhering to strict coding standards and robust testing methods.
• Collaborate synchronously with core product and engineering teams.

Required Skills

Candidates must display proficiency and experience in various key areas:

• 5+ years of professional experience in full-stack JavaScript/TypeScript applications.
• Comfort in handling asynchronous programming challenges, race conditions, and memory management in Node.js.
• In-depth knowledge of React, including state management, rendering optimization, and UI component construction.
• Strong communication skills in English, with a focus on live collaboration and architectural justification.
• Experience with cloud technologies (AWS or GCP), CI/CD pipelines, and containerized environments using Docker (preferred).

Compensation and Work Environment

POS+ offers competitive compensation tailored to geographic location and level of expertise, ensuring it remains attractive to top-tier talent. The role comes with the following benefits:

• Direct Contractor Engagement with streamlined contracting processes and monthly invoicing.
• Emphasis on autonomy, allowing engineers to work independently while being responsible for their modules and code quality.
• Opportunity to make an impact by working on core systems affecting thousands of transactions daily in real-world merchant settings.
