Founding Member of Technical Staff
San Francisco Bay Area
In office
Full-time
As a Founding MTS, you’ll join at the true zero-to-one stage. Leveraging AI heavily, you’ll work side by side with the founding team to architect and build the core product, work closely with customers, solve challenging technical problems around large-scale AI-powered application building and data integrations, and ship features that create immediate real-world impact. This is a rare opportunity to influence both the technology and culture of a venture-scale company from the beginning.
What you’ll do
- Design and build core systems from scratch
- Own technical decisions across the stack, from AI tools to backend architecture and deployment.
- Work on problems at the edge of AI app generation using LLMs, AI reasoning, RL-trained verifiers, enterprise AI deployments, and data integrations.
- Collaborate directly with customers and founders to drive rapid iteration and impact
What we’re looking for
- 3+ years of software engineering or research experience (bonus for startup or high-growth background)
- Strong fundamentals in either AI research, AI solutioning, or full-stack engineering & system design
- Comfortable working in ambiguous and fast-moving environments
- Entrepreneurial mindset and eagerness to shape a product from the ground up
Why join
This is a true day-zero, founding-level role:
- Redefine how software is built and used at enterprises today using AI
- Build core systems that define the trajectory of the company
- Significant QSBS-eligible equity and competitive compensation with massive upside
- Backed by top-tier investors and Fortune 100 design partners already showing interest
- Access to the best operators, capital, and networks in the industry
- Learn what it takes to build a successful company
- Work directly with experienced founders with AWS/FAIR/Hugging Face backgrounds and world-class investors
- Opportunity to have outsized ownership and impact at the earliest stage
