Tech Lead (Applications and Solutions)

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.

Technology environment

React, JavaScript, Django, Django REST Framework, Django Channels/ASGI, Python, Node.js/Express, Celery, Redis, Nginx, and AWS (EC2, ALB, S3, CloudFront, ACM, IAM, VPC, and Route 53). Product integrations include OpenLayers, three.js, Autodesk Platform Services, Sketchfab, Stripe, and Google Maps. This describes the current environment; the lead will help determine its evolution.

What you bring

• Substantial experience building and operating production web applications across frontend, backend, APIs, and cloud services, with strong hands-on React and Python/Django capability.
• Experience leading technical design and delivery, reviewing code, mentoring engineers, and aligning technical decisions with product and customer needs.
• Practical AWS and DevOps experience, including IAM and network security, deployment automation, monitoring, and incident troubleshooting.
• Ability to design secure integrations and data flows, manage technical debt, and improve reliability without blocking delivery.
• Clear communication with technical and nontechnical stakeholders, including the ability to explain priorities and tradeoffs in plain language.

Useful additional experience

Django Channels and WebSockets; Celery and Redis; Node.js; WebGL or three.js; geospatial applications; CAD/BIM formats and Autodesk Platform Services; drone imagery workflows; Terraform or CloudFormation; GitHub Actions with OIDC; Docker; and payment integrations.
