Principal Software Engineer

Lead the architecture, development, and delivery of high-throughput, multi-tenant Tier 0 services, balancing scalability, reliability, security, performance, cost, and maintainability. Define and drive technical direction for complex distributed systems, anticipating failure modes, cross-service dependencies, capacity constraints, and potential blast radius before implementation. Design and build secure, extensible, performant, and thoroughly tested software while setting a high engineering-quality bar through hands-on technical leadership. Establish and scale engineering practices, coding patterns, observability standards, and service-health metrics that improve quality, operational efficiency, and long-term reliability. Lead complex live-site investigations, mitigation, root-cause analysis, and post-incident improvements using telemetry, logs, experimentation, and other diagnostic methods. Identify technical risks, dependencies, and unknowns early; communicate their potential impact and drive mitigation strategies that keep engineering efforts moving forward. Lead architecture, design, and code reviews; build alignment around technical decisions and clearly communicate strategy, tradeoffs, and risks across teams. Partner across engineering, product, security, and other disciplines to resolve ambiguity, align dependencies, and deliver durable solutions spanning multiple services and teams. Mentor and develop engineers through technical guidance, constructive feedback, knowledge sharing, and inclusive, hands-on leadership. Apply an AI-first mindset to create intelligent product capabilities and improve software design, development, testing, deployment, monitoring, and operations.
