Software Engineer, Home Design Experience

Higharc is a startup changing how new homes are designed and built through software. The Staff Software Engineer will lead the architecture and delivery of the Home Design Experience, a browser-based 3D home design application, while writing production code, making technical decisions, and mentoring engineers. The role also involves building AI-supported experiences and partnering with product, UX, and platform teams.

Responsibilities:

• Rapidly prototype new home design workflows and turn the ones that land into customer-ready software
• Lead development of interactive 3D home design workflows, connecting the application UI, design data, and real-time 3D scene into a responsive experience. Build AI-supported and agentic interactions that help users design their homes
• Own application architecture and technical delivery from early prototypes through production. Make decisions across the frontend, application state, and service integration, including performance, reliability, and testing
• Be an independent technical partner to the product/UX lead: challenge assumptions, identify risks early, propose alternatives, and help decide what to build next
• Turn ambiguous goals into concrete implementation plans, resolve technical unknowns through working code, and implement the critical pieces yourself to keep delivery moving
• Partner with the platform team to use and improve shared application foundations. Identify which patterns should be reused across Higharc and help implement and document them, keeping immediate product delivery central to those decisions
• Help less experienced engineers take ownership through pairing, code review, and clear technical guidance. Establish patterns they can confidently extend

Requirements:

• A track record of personally architecting, building, and shipping substantial web applications, with responsibility for technical decisions from initial implementation through production use
• Deep hands-on experience with TypeScript, React, and modern web application architecture, including application state, API integration, performance, and maintainability
• Genuine enthusiasm for AI-forward development and for building AI-supported or agentic product experiences
• Experience making technical decisions independently in partnership with a product or design lead. You can explain tradeoffs, challenge a proposed approach constructively, and commit to a path forward
• Sound judgment about what to build for the immediate product and what to generalize for reuse, with experience collaborating across application and platform teams
• Experience helping less experienced engineers deliver through implementation, mentoring, and technical guidance
• A growth mindset and real ease with ambiguity, on a team and product area that's still being defined
• Strong instincts for design and craft, even though you're not the designer on the team
• A strong plus: hands-on experience with Three.js and browser-based 3D applications, especially design or CAD tools. You'll be helping people design homes in 3D, so experience making complex spatial interactions intuitive is particularly valuable
