Founding Full Stack Engineer

Founding Full-Stack / Product Engineer (Onsite — San Francisco, CA) Location: San Francisco, CA (onsite)

Employment Type: Full-time

About the Role

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.

What We’re Looking For

3-7 years of professional software engineering experience.

Strong TypeScript/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.

Nice to Have

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.

Why This Role

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.
