Backend by top VCs and trusted by leading collectors, advisors, and institutions.Job Objective:We're hiring aStaff Fullstack Engineerto be a technical leader who can move fluidly across the entire stack—from database design to user interfaces.
As one of the first fullstack hires, you'll own end-to-end features, establish fullstack engineering standards, and serve as a bridge between our backend and frontend tech leads.
This is asenior technical rolewith high autonomy and the opportunity to mentor future fullstack engineers as the team scales.Reporting & Collaboration:You'll report directly to ourHead of Engineering,a highly hands-on technical leader who you'll partner with on cross-stack architecture and technical strategy.
You'll work closely with our Staff Backend and Staff Frontend engineers to ensure seamless integration across the platform, and help define patterns that enable rapid end-to-end feature delivery.You'll also collaborate closely with our CPO (Chief Product Officer), designers, and company leadership to rapidly prototype, test, and iterate on new tools and user experiences.
This isn't just about implementing tickets—it's about owning entire features from conception to production, making smart tradeoffs, and shipping intelligent, scalable applications quickly.This is a hands-on, high-ownership role.
We move fast using tools like Cursor and Claude Code, and actively leverage AI in our product and development workflows.
This is an adecuado role for someone who thrives in early-stage environments,



enjoys rapid prototyping and iteration, and believes AI development tools can 10 X their output.Responsibilities:
Technical Leadership & Ownership:

Collaborate with product and designto rapidly prototype, test, and iterate on new tools and user experiences
Build intelligent interfacesthat surface LLM outputs, human-in-the-loop workflows, and real-time data insights
Work across layersto integrate with backend APIs, data services, and AI pipelines
Contribute to both frontend and backend architecture , including component design,state management, API patterns, and performance optimization
Own features from DB to UI , including schema design, business logic, API endpoints, and user interfaces
Ship fast, learn from users,and continuously improve the product based on real-world feedback
Cross-Functional Collaboration:
Partner with Head of Engineeringon cross-stack technical decisions and architecture
Collaborate with Staff Backend and Staff Frontend engineersto define integration patterns and shared standards
