You think from first principles and have a track record of solving complex, real-world problems. * Hands-On Builder: You're happiest writing code and shipping production systems in a fast paced startup --- not just managing others. * Self-Directed & Autonomous: You thrive in a lightly structured environment, decomposing ambiguous problems and independently driving them to completion. * Backend, Security & Systems Focused: Most work centers on backend and business logic development and integrations. Security-centric SRE experience is preferred. Frontend development is helpful but not central. * Startup & Enterprise Experience: You balance startup agility with enterprise-scale thinking and rigor. * Smart, Not Hard: You work efficiently and sustainably, typically producing exceptional results within a 45--50 hour workweek. * AI & LLM Experience: You're excited by building in an *AI-native environment* , leveraging Claude Code and other LLM-assisted tools to enhance development velocity and creativity. * Collaborative & Solution-Oriented: No lonewolves. You communicate thoughtfully, contribute positively to discussions, and pair every critique with a constructive solution. ## Description * Architect and implement core systems for an AI-powered enterprise collaboration platform, as a core engineer. * Define, design, and deliver innovative solutions in distributed systems, backend logic, and AI integration. * Collaborate closely with product, design, and AI research peers to shape both strategy and implementation. * Ensure infrastructure reliability, scalability, and security through modern cloud and Kubernetes technologies. * Work with other Senior Staff Engineers to foster a culture of technical excellence, autonomy, and curiosity., * We value leverage over brute force --- working smart, not long hours. Engineers are trusted to define their own work, prioritize high-impact projects, and deliver results with minimal oversight. * The team collaborates through lightweight, peer-driven conversations rather than rigid sprint cycles or daily standups. You'll work alongside senior peers solving challenging systems problems in a small, high-trust team where every hire makes a visible impact. * This is an environment for creative, disciplined problem solvers who thrive in freedom and accountability., * Work at the bleeding edge of containerization, Agentic platforms, MCP, and distributed systems. * A modern, cloud-first infrastructure built on Knowledge Graph using Neo4J and Terraform and Kubernetes. * High-impact autonomy: engineers research, design, and deliver major systems end-to-end.
