Founding Full-Stack / Product Engineer (Onsite — San Francisco, CA)
Location:
San Francisco, CA (onsite)
Employment Type:
Full-time
We’re building a new category of sales performance technology that helps go-to-market teams observe and replicate top-performer behaviors. The product is scaling quickly with enterprise adoption, and we’re doubling headcount this year. As a Founding Engineer, you’ll own major chunks of architecture, performance, and product direction—shipping fast, talking to customers, and shaping what the platform becomes.
This is a true 0-1/1-n role for someone who loves full-stack work, thrives in ambiguous environments, and wants outsized ownership and impact.
What You’ll Do- Build and ship end-to-end features across React/Next.js (frontend) and Node.js/NestJS (backend).
- Design reliable data models and services using PostgreSQL and MongoDB.
- Integrate backend services with Python FastAPI endpoints that power ML workflows.
- Drive architectural decisions to improve performance, scalability, and developer velocity.
- Contribute to AWS infrastructure, deployment strategies, and CI/CD pipelines.
- Collaborate directly with founders and early customers; scope and deliver customer-facing projects.
- Maintain high code quality through reviews, testing, and clear documentation.
- Gather early user feedback and iterate quickly.
- 3-7 years of professional software engineering experience.
- Strong Type Script/JavaScript across the full stack.
- Proficiency with React/Next.js and Node.js/NestJS.
- Comfort owning projects end-to-end in a fast-paced startup environment.
- Excellent communication; able to work directly with customers and stakeholders.
- Onsite requirement: role based in San Francisco.
- Experience with Python (FastAPI) for ML integrations.
- AWS cloud infrastructure and CI/CD experience.
- Background in sales tech, AI, or B2B SaaS.
- Early-stage/founding engineer experience and/or meaningful side projects.
- Founding-level ownership and impact during a period of rapid growth.
- High velocity team culture with clear product-market pull.
- Opportunity to help define the engineering org and best practices as we scale.
- Learn a ton, fast—across product, customers, systems design, and team building.
