Senior Frontend Engineer

About the Role This is a high-ownership Senior Frontend Engineering role at a fast-growing AI platform company serving the logistics and trade compliance industry. You'll architect and evolve a real-time, data-intensive product used daily by operations teams navigating complex global trade workflows - bridging sophisticated backend AI with the humans who depend on it. What You'll Do Lead the migration and evolution of frontend architecture to support real-time, data-heavy dashboards using TypeScript, React, and Tailwind CSS. Build intuitive human-in-the-loop AI interfaces that make automated workflows transparent, explainable, and easy for operations teams to manage. Own the full product lifecycle - from technical discovery and scoping through to production monitoring. Define frontend technical vision, mentor incoming engineers, and raise the bar for engineering culture. Ensure core services maintain high uptime while gracefully handling unpredictable real-world document inputs. Work directly with leadership and customers to understand operational needs and ship fast. What We're Looking For 6-8+ years of professional software engineering experience in high-growth, fast-paced environments. Deep proficiency in TypeScript and React, including architecting complex state management for data-intensive applications. Strong command of Python for backend services and advanced SQL (PostgreSQL) for database design and query optimization. Prior startup experience in a meaningful engineering role (not just a small side project). Bias for action - prefers shipping over over-engineering and drives cross-functional delivery with minimal supervision. Solid CS fundamentals and engineering foundations. Experience integrating AI APIs and handling complex document extraction workflows is a plus. Familiarity with logistics, supply chain, or enterprise workflow software is a plus. Compensation & Benefits Base salary range: $180,000 - $260,000 USD annually, plus equity. Visa transfers (H-1B, OPT, O-1) are considered; new visa sponsorship is not available. Location On-site in San Francisco, CA. Candidates must be based in or willing to relocate to San Francisco.
