Preferred:
• Bachelor’s degree in computer science or similar discipline
• Proven experience as a technical lead, staff engineer, or principal engineer on production systems with significant user bases and business-critical requirements, with responsibility spanning multiple layers of the stack
• Track record of leading large-scale migrations, architectural overhauls, or platform rewrites across frontend and backend systems while maintaining product velocity and system reliability
• Deep expertise building and optimizing complex, data-intensive applications with demanding performance requirements (real-time processing, large-scale datasets, complex visualizations, distributed systems) across the full stack
• Advanced proficiency with Three.js, React Three Fiber, WebGL, or other web-based 3D rendering technologies, including low-level performance optimization and shader programming
• Deep mastery of OTP including BEAM scheduling, GenServers, run queues, pg, the Actor model, dynamic supervisors, registries, distributed process groups, and custom OTP behaviours, with experience pushing the boundaries of the runtime
• Advanced experience with database design and optimization at scale, including PostgreSQL internals, replication strategies, and data modeling for distributed systems
• Extensive experience with monitoring, observability, and distributed tracing across the full stack, including designing observability strategies and incident response frameworks
• Experience bridging engineering and design through deep UI/UX collaboration, design systems development, and tools like Figma, able to influence design decisions with technical constraints and possibilities
• Experience in highly regulated industries (aerospace, defense, healthcare, finance) with understanding of compliance, security, and operational constraints
• Published technical writing, open source contributions, or conference speaking that demonstrates thought leadership
• Exceptional communication skills that enable you to influence technical and non-technical stakeholders at all levels of the organization
