About Clash Nexus AI

Clash Nexus AI is an AI-powered construction technology platform that helps contractors, engineers, consultants, and preconstruction teams identify drawing conflicts, missing information, coordination issues, specification gaps, and constructability risks before they become RFIs, delays, rework, or change orders.

We already have a live production platform, active customers, and an existing codebase. We are now looking for a Founding CTO to take ownership of the technology and help scale the Company.

The Role

This is a hands-on technical leadership role, not a management-only CTO position.

The Founding CTO will work directly with the Founder & CEO and lead the technical vision, architecture, reliability, security, AI strategy, infrastructure, and engineering roadmap of Clash Nexus AI.

You will be expected to write and review code, improve the existing platform, solve production issues, and build the engineering team as the Company grows.

Key Responsibilities

Own the existing production codebase, architecture, infrastructure, and technical roadmap
Lead full-stack development across frontend and backend systems
Build and maintain backend services, APIs, and data pipelines
Improve AI accuracy, reliability, monitoring, and evaluation
Manage AI/ML, OCR, and third-party technology integrations
Establish strong testing, CI/CD, security, deployment, and release practices
Improve scalability, performance, and technical reliability
Support customer demos, enterprise evaluations, and technical diligence
Recruit and manage engineers and technical contractors as the Company grows
Maintain technical documentation and reduce key-person dependency

Required Experience

Strong professional full-stack development experience
Strong hands-on knowledge of Python
Experience building scalable SaaS or cloud-based applications
Strong backend, API, database, and software architecture experience
Experience with modern frontend technologies
Hands-on experience with AI/ML, LLMs, APIs, data pipelines, or document-processing systems
Experience with cloud infrastructure, CI/CD, monitoring, and production deployments
Strong understanding of security and customer-data protection
Startup, founding engineer, technical lead, senior engineer, or CTO experience is highly preferred
Construction, AEC, BIM, OCR, computer vision, or document-AI experience is an asset

Compensation

This is initially an equity-based Founding CTO opportunity.

The successful candidate will have the opportunity to participate meaningfully in the long-term value created by Clash Nexus AI through performance-based equity.

The Company intends to transition the role into a salaried executive position as agreed Company milestones are achieved and the business continues to grow.

Full equity, compensation, and milestone terms will be discussed with selected candidates and documented in the formal employment and equity agreements.

Who We Are Looking For

We are looking for a technical builder who wants to take ownership, move fast, solve difficult problems, and help build the Company from an early stage.

This role is best suited for someone who wants to be both a hands-on engineer and a technical leader, with the ambition to build and lead the engineering organization as Clash Nexus AI scales.

To apply, please include your résumé or LinkedIn profile, GitHub or portfolio where available, and a short summary of your full-stack, Python, SaaS, and AI experience.

Requirements

The role requires strong professional full-stack experience, hands-on Python expertise, and experience building scalable SaaS or cloud applications with robust backend, API, database, and architecture skills.
