• Proficiency in TypeScript and JavaScript , with clean, maintainable component architecture
• Familiarity with frontend performance profiling , accessibility, and design system integration

Responsibilities

• Lead End-to-End Builds
• Own projects across the full development lifecycle - from greenfield prototypes to scaling out mature systems. You’ll take loosely defined problems and return well-architected, production-ready solutions
• Design for Clarity and Change
• Build backend services and user interfaces that are modular, testable, and ready to evolve. You prioritize simplicity, knowing where abstraction helps - and where it just adds noise
• Drive Pragmatic Scalability
• Design for growth without overengineering. You’ll apply best practices in schema design, API modeling, and state management with a clear sense of tradeoffs and long-term maintainability
• Collaborate Closely
• Partner with product, design, and other stakeholders to understand real-world needs and shape the right technical solutions. You'll operate autonomously but never in isolation
• Continuously Level Up
• Bring curiosity and humility. We’re a senior team that shares learnings freely and pushes each other to do our best work

Preferred Qualifications

• You know how to ship fast without creating tech debt landmines
• You balance product intuition with a strong technical foundation
• You default to clarity and modularity, especially when designing for unknowns
• You’ve worked at early-stage startups or launched new systems from scratch
• You value peer collaboration and open sharing of technical learnings
• You care just as much about why you're building something as how you build it

Benefits

• Competitive compensation
• Equity participation: Employee Stock Options
