Mainstay is hiring a Real Estate Agent for the single-family rental industry, fully remote within the US. The role involves managing both sides of residential property transactions (acquisitions and dispositions) for institutional buyers/sellers: putting together offers, negotiating, managing listings, and keeping deals together. Requires 5+ years of active real estate transaction experience. This is a real estate brokerage role supported by AI tools, not a software engineering position.

Mainstay is an AI-native market intelligence platform for the single-family rental industry, spun out from Opendoor in 2024 and backed by Khosla Ventures. This full-stack senior software engineer role sits on the core platform team and involves designing and shipping AI-powered workflow management systems that enable operations at scale—from retrieval pipelines and guardrails to backend services and user-facing product. You'll contribute across the entire development lifecycle, own technical decisions for systems directly influencing investor decision-making, and work closely with product, design, and data teams; the tech stack is Python, TypeScript, React, and AWS. The role requires 5+ years building production-grade software at early-stage startups with proven hands-on experience deploying production AI features, strong full-stack skills with Python backend expertise, React frontend experience, and comfort with data-heavy systems and ambiguity. This is a particularly strong fit if you want end-to-end ownership of high-leverage systems and enjoy working at the intersection of data, product, and business impact, but won't work if you lack backend depth, prefer narrow scope over ownership, or struggle with cross-functional collaboration. Notably, the company emphasizes autonomy and iteration in a remote, collaborative environment—this is an AI-first role where you'll use AI to ship reliably across the stack.
