AI Application Builder (Vibecoding) - Masters-Level Internship

About Us

Vosyn is a Language Synthesis AI company based in Toronto. We build technology that removes language barriers, so people can access and understand information in any language. We are preparing for an IPO, and the people who join us now help shape both the product and the company itself. Good ideas get heard here, whoever they come from.

About the Role

We are seeking a resourceful, fast-moving AI Application Builder Intern to join our team. This role is ideal for a Master’s level student who builds software primarily by directing AI coding tools rather than writing every line by hand a practice often called “vibecoding.” You will turn briefs, rough requirements, and client roadmaps into working web applications, internal tools, and prototypes at speed, then wire them up to the AI and data layers your teammates build. The ideal candidate knows how to scope a build, prompt iteratively, review and debug AI-generated code, and ship something that actually works and, just as importantly, knows where vibecoding stops and careful engineering has to take over.

Key Responsibilities

• Build responsive web applications, internal tools, and landing pages primarily through AI coding tools such as Cursor, Lovable, Bolt, or v0.
• Translate written briefs, feature requests, and client roadmaps into working, deployable software.
• Prompt iteratively and refine AI-generated output to meet functional and design requirements.
• Review, test, and debug AI-generated code to ensure it is correct, secure, and maintainable - not just “it ran once.”
• Integrate front-end builds with the back-ends, agents, and retrieval services built by the Applied AI and Integration engineers so data and AI features flow end to end.
• Recognize where vibecoding is the right tool and where a problem needs hand-written code or a teammate’s help, and escalate accordingly.
• Deploy applications, gather feedback, and iterate quickly.• Document your work in Notion so others can pick it up.

About You

• Educational Background: Currently enrolled or recently graduated from a Master's program in Computer Science, Software Engineering, or related fields.
• Experience: Strong, demonstrable hands-on experience building applications with AI coding tools such as Cursor, Lovable, Bolt, or v0 - portfolio or shipped work preferred.
• Code Judgment: Able to review, test, and debug AI-generated code for correctness, security, and maintainability - "it ran once" is not your standard.
• Prompting Skills: Excellent iterative prompting and the judgment to know when a problem needs hand-written code instead.
• Coding Fluency: JavaScript/React and/or Python sufficient to fix and extend generated output.
• Communication Skills: Excellent verbal and written communication within a cross-functional team environment.

We believe exceptional talent often emerges from diverse paths. If you possess a profound curiosity, a genuine passion for continuous personal and professional growth, and a strong desire to apply your unique abilities to create significant impact within our team, we strongly encourage you to apply - even if your background doesn’t align perfectly with every single qualification.

Why Join Us

• Work inside a start-up as it prepares for an IPO, and see how that actually gets done.
• Work directly with senior management and members of the advisory board.
• Build experience you can point to: real projects with real outcomes.
• Take ownership of work that matters to the company, with the pace and responsibility of a start-up.

DEI and Workplace Safety

Vosyn is an equal-opportunity employer. We hire people from different backgrounds, disciplines, and countries because the work is better for it, and we want every member of the team to feel respected and supported. We take workplace safety seriously, follow the regulations that apply to us, and expect everyone here to look out for one another. If that sounds like a place you would want to work, we encourage you to apply.

Tools & Tech Stack

• AI-native IDEs / editors: Cursor, GitHub Copilot, Windsurf, or Cline • Prompt-to-app builders: Lovable, Bolt.new, v0 (Vercel), or Replit Agent • Front-end frameworks: React.js / Next.js (the typical output of these tools) • Backend-as-a-service: Supabase or Firebase • Version control: Git / GitHub • Collaboration & documentation: Notion
