Senior Full-Stack Software Engineer

## About the Role We are looking for a Senior Full-Stack Software Engineer to guide full-stack development on a creative platform designed for large-scale, design-focused workflows. This role bridges detailed, interactive frontend interfaces and robust, high-performing backend systems. It involves more than delivering features; it includes setting the architecture, shaping long-term technical goals, and supporting the engineers on your team. In this role, you will take on complex, open-ended problems, translating ambiguous requirements into well-scoped technical approaches and driving them through to production. This position offers significant technical scope, with direct influence on both the product and the engineering foundation it is built on. ## What You'll Do - Help establish architecture and quality coding practices for the platform's client and backend systems. - Define long-term technical solutions spanning the entire technology range, working closely with product and development to translate early ideas into well-engineered, production-ready experiences. - Compose and build fast, responsive, visually rich frontend interfaces that meet high design fidelity standards, using modern web frameworks and component-based architecture. - Architect backend services built for heavy traffic and high reliability, with emphasis on performance, fault tolerance, and observability. - Own the development and operation of controlled environments built for development, testing, and platform instance isolation. - Drive deployment strategy and infrastructure on Kubernetes-based clusters, including decisions around rollout, reliability, and operational efficiency. - Lead adoption of AI-assisted engineering practices across the team. Use tools like Claude Code, Cursor, and Codex to improve implementation speed and code quality. Help others integrate these tools into their workflows effectively. - Define and improve the developer experience: local development loops, CI/CD ergonomics, and tooling that keeps the team productive as the codebase grows. - Engage with customers and internal collaborators to identify problems, evaluate solutions, and refine workflows. - Mentor engineers on the team through code review, development feedback, and sharing technical knowledge across the stack. ## What You'll Need - Bachelor or Master's degree in Computer Science, Software Engineering, or a related field, or equivalent experience in practice. - Practical experience developing and delivering production-quality full-stack systems, demonstrating comprehensive technical responsibility on complex products. - Proficiency in modern frontend development, including frameworks such as React, with experience building interactive, design-heavy, high-performance UIs. - Experience in backend engineering developing and managing scalable services under high traffic, emphasizing reliability, performance, and fault tolerance (e.g., Node.js, Java, Python, Go, or similar). - Good engineering craft: readable, well-structured, production-quality code; clear opinions on testing strategy, system development, and long-term maintainability. - Experience deploying and operating services on Kubernetes-based infrastructure, including container orchestration, cluster management, and production reliability practices. - Practical experience with AI-supported engineering tools (Claude Code, Codex, Cursor, or similar) and a proven history of incorporating these into actual development processes. True passion for the possibilities AI-enhanced engineering offers. - Proficiency with CI/CD practices and good instincts for developer experience and tooling. - Good written and verbal communication skills, with the ability to articulate deep technical decisions to both engineering and product collaborators. ## Nice to Have - Experience crafting and managing sandbox-based environments for multi-tenant or isolated workloads. - Background in building or contributing to internal developer platfor…
