• You raise the bar for engineers around you

Experience & Expertise

• 5+ years in full stack development, owning production systems end-to-end

• Experience influencing architecture and mentoring others
• Bonus: Experience in real estate technology

Qualifications

• Degree in Computer Science, Software Engineering, or equivalent experience
• Cloud or AI/ML certifications are a plus

Key Responsibilities

• Use AI coding assistants and agentic tools to accelerate development (scaffolding, refactoring, testing, documentation)
• Build automated engineering workflows (code review support, API scaffolding, migrations, test generation)
• Integrate LLM-powered features into products (e.g. intelligent search, document processing, reporting)
• Evaluate and drive adoption of emerging AI development tools

Product & Technical Leadership

• Translate ambiguous business problems into clear technical solutions
• Lead requirement discovery with stakeholders and challenge assumptions early
• Contribute to architecture and technical strategy—not just delivery
• Mentor engineers and elevate team standards through collaboration

Full Stack Development & Architecture

• Build scalable, performant frontend and backend systems
• Design secure RESTful and GraphQL APIs
• Own integrations with third-party systems (CRM, ERP, property platforms)
• Optimize data models and system performance as the product scales

Quality, Testing & Delivery

• Implement robust automated testing (unit, integration, E2E, AI-assisted)
• Improve CI/CD pipelines and release processes
• Maintain high standards for code quality, security, and maintainability
• Respond to production issues with a root-cause mindset

Who You Are

• You take ownership and move things forward without waiting
• You embrace AI as a productivity multiplier—but think critically
• You have deep technical expertise and care about quality
• You think beyond tickets and focus on solving real problems
• You continuously learn and apply new technologies
• You elevate the people and systems around you
