Familiarity with construction, real estate, or PDF workflows is a bonus. Proficiency with Tailwind CSS is a nice-to-have. Empathetic, honest communicator who thrives in a small, fast-moving team. Genuine motivation to make housing more accessible, not just to maximize compensation. Exceptional recent graduates with strong fundamentals and hustle are welcome to apply.
