Senior architecture role acting as the bridge between business requirements, product strategy, and engineering execution, ensuring complex systems are architected for long-term scalability, reliability, and maintainability. Designs scalable, secure, high-performance architecture across application, data, and infrastructure layers (about 35 percent of time), provides technical leadership and engineering alignment (25 percent), owns integration and platform strategy (20 percent), drives technical problem solving and performance optimization (10 percent), and maintains architecture governance and documentation (10 percent). In the first 90 days: deep dive into product architecture, infrastructure, APIs and data flows; review system design and deployments and identify scalability, performance and reliability improvements; lead architecture for key capabilities and produce solution documents; guide engineering on best practices; then own end-to-end architecture delivery, drive architecture reviews, and align teams with business goals. Requires 5-10 years of backend engineering experience, strong expertise in distributed systems and scalable backend architectures, deep understanding of databases, query optimization and performance, experience building high-scale backend infrastructure, and the ability to mentor engineering teams. Tech stack: Golang preferred, SQL and distributed databases, modern cloud-based infrastructure.
