OneSeven Tech (OST)
Argentina · Full-time · Mid-Senior

First Engineering Hire | Build the Future of Code Quality

CodeOpps is solving one of software development's most critical challenges with AI that audits, fixes, and tracks tech debt. We've completed multiple audits and validated strong demand from companies ranging from venture-backed startups to legacy SMB's and PE/M&A firms seeking technical due diligence. Now we're building the world's largest code dataset to power next-gen AI coding tools for digital transformation.

The Role

As our first AI-First Full-Stack Engineer, you'll build the core systems connecting GitHub repositories to AI-powered auditing engines and create enterprise dashboards that process millions of lines of code. You'll also assist with manual audits for new customer sales while we complete the fully automated AI version - giving you invaluable insights into tech debt patterns.

This isn't just development work—you're solving a problem where 66% of software projects fail due to tech debt and 30% of developer time is wasted maintaining bloated systems.

About You

You're an AI-first developer who uses tools like Cursor, Claude, Windsurf, GitHub Copilot, and ChatGPT to program faster and build intelligent applications. You're an integration specialist who can INTEGRATE ANYTHING - whether it's Nylas, GitLab, Slack, or any other platform.

You thrive in fast-paced environments, can work extra hours when needed, and are comfortable with 1-week production-ready sprints. You can build complete web applications end-to-end and write comprehensive unit tests for all your code.
