Role summary You will lead the design, development, integration, and operation of H3Zoom’s web applications and customer-facing solutions. You will set technical direction across frontend, backend, real-time services, and cloud infrastructure while contributing code to the most important or complex work. Working with product, AI and data engineering, R&D, field operations, and customer-facing teams, you will turn inspection workflows into secure, usable, maintainable software. You will guide engineers and external delivery partners as the team grows. Key responsibilities • Own application architecture and technical roadmaps for Facade Inspector, Site-Check, and related solutions; make and document pragmatic tradeoffs on scalability, maintainability, security, and cost. • Lead delivery from discovery and solution design through implementation, testing, release, and production support; break requirements into clear milestones and coordinate dependencies across teams. • Contribute hands-on to our React frontend, Django and Django Channels backend, Node/Express services, APIs, WebSocket features, and asynchronous processing with Celery. • Design integrations for drone and 360° imagery, geospatial maps, 3D/BIM viewing, Autodesk Platform Services, and other external services where customer workflows require them. • Establish engineering practices for Git, code review, automated testing, CI/CD, observability, incident response, documentation, and reproducible infrastructure. • Own the technical health of the H3 Zoom application ecosystem, including access control, secrets, deployment pipelines, performance, and availability. • Mentor engineers through design reviews, pairing, feedback, and clear standards; assess technical work by vendors and partners when needed. • Work directly with stakeholders to scope feasible solutions, explain technical tradeoffs, and support customer implementation and issue resolution.
