Responsibilities

• Set architecture and technical priorities for major parts of the product, from web applications and APIs to event-driven systems.
• Design and deliver scalable features, contributing deeply in React, Next.js, and TypeScript or backend services in Go while working across the stack.
• Turn ambiguous, cross-team problems into clear proposals, delivery plans, and measurable outcomes; own initiatives from discovery through deployment and iteration.
• Work with product, design, infrastructure, and platform partners to balance usability, accessibility, performance, security, reliability, and delivery pace.
• Improve engineering quality through design and code reviews, testing, observability, safe releases, and mentoring.
• Establish responsible practices for AI-assisted development, including review, security, and validation standards.

Requirements

• Substantial experience building and operating scalable production systems, with technical leadership at Staff level or comparable cross-team scope.
• Deep expertise in either React-based web applications with JavaScript or TypeScript, or backend services using Go, Java, Python, or similar; ability to reason across the full stack.
• A record of setting technical direction and delivering complex work from uncertain requirements to measurable production results.
• Strong architectural judgment, including system boundaries, tradeoffs, and evolving systems as needs and scale change.
• Experience with modern web architecture and state management, or with data modeling, distributed systems, and event-driven design.
• Clear communication and collaboration skills, including the ability to mentor, align teams, and create clarity as priorities shift.

Nice to have

• Experience with real-money transactions, financial correctness, auditability, or regulatory requirements; multi-team roadmaps; developer productivity; or security-minded AI engineering practices.
• Experience establishing technical foundations in a startup or high-growth product environment.
