Role Overview

The Role: Build the Product Experience

As a Frontend-Leaning Full-Stack Engineer, you’ll play a central role in shaping the product experience from day one. You’ll own complex, data-heavy user interfaces while collaborating closely with backend systems to deliver fast, intuitive, and reliable workflows.

This is a high-impact role for engineers who enjoy product ownership, move quickly, and care deeply about usability and clarity in complex systems.

Key Areas of Responsibility

• Own the Frontend Experience: Design, build, and maintain responsive, data-dense dashboards and workflows using modern frontend frameworks
• Translate Complexity into Clarity: Work closely with backend systems to surface complex logistics and AI-driven data in a way that is intuitive for users
• End-to-End Feature Delivery: Take ownership of features from product discovery and technical design through production release and iteration
• Collaborate on System Design: Contribute to API design, data contracts, and system architecture to ensure frontend and backend scale together
• Mentor and Scale: Help shape engineering best practices, contribute to team culture, and support future hires as the team grows

Technical Requirements

• Experience: 3–5 years of professional software engineering experience, ideally in a startup or high-growth environment
• Modern Frontend Expertise: Strong proficiency in React, with experience building complex, high-performance user interfaces
• Full-Stack Capability: Comfortable working across the stack, including backend services (e.g., Python) and APIs
• Data & APIs: Solid understanding of how frontend systems interact with APIs, databases, and real-time data
• Databases: Working knowledge of SQL (PostgreSQL) and data modeling to support frontend use cases
• AI/ML Integration (Plus): Familiarity integrating AI APIs (OpenAI, Anthropic) or consuming outputs from vector databases is a bonus

Success Metrics (How We’ll Measure You)

• Feature Velocity: Ability to ship polished, user-facing features quickly from wireframe to production
• Frontend Quality: Performance, reliability, and usability of frontend systems in production
• Code Quality: Clean, maintainable, well-documented code that scales with the team
• Product Impact: Measurable improvements in user adoption, workflow efficiency, and overall product experience
• Autonomy: Ability to solve complex product and technical problems with minimal supervision

Is This the Right Fit?

You’ll Love This Role If You:

• Thrive in early-stage, zero-to-one environments
• Are a product-minded engineer who cares deeply about user experience
• Prefer ownership and trust over rigid ticket queues
• Enjoy turning complex systems into simple, usable interfaces

This Might Not Be for You If You:

• Prefer working only on isolated frontend components with little backend context
• Need heavy process, large teams, or fixed long-term roadmaps to be productive
• Are uncomfortable with ambiguity and rapid iteration in an early-stage startup
