Vibe Engineering: AI-Assisted Development & Productivity
We believe that modern developers leverage state-of-the-art dev tools to maximize engineering efficiency.
The ideal candidate is experienced with AI-assisted development workflows, leveraging tools such as GitHub Copilot, Cursor, or similar LLM-based environments to rapidly prototype, debug, and evolve complex systems.
You should be comfortable translating ambiguous problem statements into iterative prompts, guiding AI agents to generate high-quality, maintainable code while applying strong engineering judgment. The role requires an ability to blend traditional software engineering practices with modern AI tooling-using automation, code generation, and conversational development to accelerate delivery without compromising architecture, reliability, or security.
