Senior Backend Engineer / Founding Full Stack Developer (Hybrid – San Francisco)

Location: San Francisco, CA (Hybrid, 2–3 days onsite)
Compensation: $160,000–$190,000 base + equity + benefits
Type: Full-Time | Founding Team Role | Early-Stage Startup


ABOUT THE ROLE

The client is building the platform that will redefine how teams use data to make fast, intelligent decisions.

Think of it as the infrastructure layer that bridges analytics, AI workflows, and real-time collaboration — built from the ground up for speed, scale, and simplicity.

As the Senior Backend Engineer, you’ll own the system architecture that powers it all. You’ll help design APIs, data models, and core backend services — while collaborating with our founders to turn big ideas into shipped features.

If you’ve ever wanted to build a 0→1 product where your architectural decisions define the company’s trajectory, this is that opportunity.


YOU’LL BE DOING
 
  • Architect and implement scalable backend systems, APIs, and data pipelines.

  • Design data models and caching strategies for real-time interactions and analytics.

  • Lead the integration of third-party APIs and internal microservices.

  • Collaborate with the product and frontend teams to deliver intuitive user-facing functionality.

  • Establish best practices around CI/CD, testing, and observability.

  • Mentor junior developers as the team grows.


 

OUR CURRENT TECH STACK

We move fast, but think long-term about architecture.
You’ll likely work with:

  • Backend: Node.js (TypeScript), Python (FastAPI), or Go

  • Frontend: React / Next.js

  • Databases: PostgreSQL + Redis for caching

  • Infrastructure: AWS (ECS, Lambda, CloudWatch)

  • DevOps: Docker, Kubernetes, GitHub Actions (CI/CD)

  • APIs: REST + GraphQL

  • Bonus: Experience with AI/ML integrations or event-driven systems


 

WHAT WE’RE LOOKING FOR

  • 5–8+ years building production-grade applications at scale

  • Deep backend expertise and comfort working full stack when needed

  • Experience designing APIs, managing data flow, and scaling systems

  • Comfort in startup environments where you build and iterate quickly

  • Excellent communication — able to explain complex ideas simply

  • Curiosity for AI, automation, and elegant architecture


WHY JOIN US

  • Shape the foundation of a product that’s still being written

  • Collaborate directly with founders who are builders themselves

  • Work on complex, meaningful technical problems

  • Competitive pay + meaningful early equity

  • Hybrid culture rooted in trust, creativity, and technical excellence
