Role Description:

We are seeking a Senior Frontend Software Engineer to help build and evolve the frontend systems that support Matterport's mobile capture and marketplace experiences. This role sits within the mobile organization and focuses on developing TypeScript-based frontend components and workflows that integrate directly into native mobile applications and connect with Matterport's 3D and platform services.

We are looking for someone who enjoys building frontend systems that operate at the intersection of mobile, platform, and 3D workflows. In this role, you'll work closely with iOS, Android, and 3D engineering teams to develop embedded frontend experiences, support capture and review workflows, and integrate Matterport technology into CoStar's marketplaces. This is not a native mobile or 3D rendering role, but a frontend engineering position focused on building reliable, maintainable, and scalable frontend functionality that lives alongside mobile products.

Responsibilities:

• Design and deliver high-quality Front End systems and user interfaces using TypeScript and modern frontend frameworks, with a strong focus on maintainability, and scalability.
• Build components and experiences that support and extend mobile workflows by embedding the components into native applications
• Develop complex workflows which can run offline and support two-way communication between native applications and web components
• Utilize libraries and frameworks to visualize spatial data within mobile components
• Stay current with evolving mobile and TypeScript ecosystems, applying new tools and patterns where they provide clear value.
• Work with a cross-functional team of product managers, designers, mobile engineers, and platform engineers to deliver features that integrate into CoStar's mobile products and marketplace ecosystems.
• Collaborate closely with 3D engineering teams to integrate frontend experiences with 3D-powered services
• Champion frontend best practices including TypeScript patterns, strong typing, performance optimizations, and clean architectural design.
• Create prototypes or proof-of-concepts to validate new frontend ideas, integrations, or platform capabilities where they intersect with mobile or marketplace products.
• Implement and maintain appropriate unit and integration tests to ensure frontend reliability and long-term stability.
• Work closely with QA and customer-facing teams to triage issues, maintain existing functionality, and improve overall product quality.

Basic Requirements:

• 5+ years of experience designing and delivering frontend applications using TypeScript
• Experience working with cross-functional teams including Product, Design, and Engineering
• Experience writing maintainable code and participating in code reviews
• Experience implementing unit and integration tests
• Familiarity working with frontend systems that integrate with backend services or platform APIs

Preferred Requirements:

• Familiarity with WebGL concepts or visualizing spatial data in frontend applications
• Experience working adjacent to 3D systems or data pipelines
• Experience using frontend frameworks or libraries to visualize maps, spatial data, or capture progress
• Exposure to mobile workflows, field tools, or capture-based products
• Experience building prototypes or proof-of-concepts
• Experience supporting frontend features used by consumer or marketplace platforms
• Prior experience in real estate, mapping, visualization, or geospatial products
