What are the responsibilities and job description for the Senior and Staff Software Engineers || San Francisco, California position at GD Resources LLC?
Role: Senior and Staff Software Engineers
Location: San Francisco, California
Our client is a fast-growing technology company reinventing how industrial businesses manage labor — developing fully autonomous, orchestrated multi-agent AI workflows that connect businesses with vetted workers to meet their staffing needs. Their mission is to build a world where the global supply chain operates at peak efficiency.
They're hiring Senior and Staff Software Engineers to join the founding team and help build their core product suite — mobile apps for both workers and businesses, and web platforms for business customers and the internal Ops team. You'll be one of the first handful of people building the SF office from the ground up, working closely with the CTO on key architectural decisions, the product roadmap, and the foundational tech platform that will scale over the next several years.
What You'll Do
- Lead frontend and backend development, guiding and mentoring other engineers when necessary.
- Architect core systems — from real-time job matching algorithms to autonomous worker vetting pipelines powered by ML and AI agents.
- Design and build scalable web and mobile applications, distributed systems, and APIs to meet the growing needs of the business.
- Partner closely with product and design to create a seamless user experience while maintaining high standards for UI/UX.
- Establish and promote best practices for code reusability, performance, and build processes across the stack.
- Implement monitoring systems for application health and performance, helping the team understand user experience and resolve issues proactively.
- Be a key player on a scrappy founding team, contributing to the future of flexible light industrial staffing.

- Proven track record with high-performance, high-caliber teams
- Strong full-stack fundamentals — TypeScript/JavaScript, React/React Native, and Node.js or Python
- High-ownership mindset; willing to do whatever it takes to drive business impact in fluid, high-context environments
