Leading the modernization and simplification of complex legacy systems to improve maintainability and developer velocity. Leading and participating in system design discussions to help the team make the right tradeoffs for a large-scale, multi-tenant, distributed system. Collaborating with Tech Leads, Product Managers, and engineers from other teams (like Plazma, Integrations, and SRE) to break down complex projects into deliverable milestones. Mentoring and coaching other engineers through pairing, constructive code reviews, and technical discussions. Proactively identifying and solving platform challenges, contributing to the team's operational excellence and long-term roadmap. Improving our engineering standards, tooling, and CI/CD processes, ensuring we can deliver value safely and quickly. Your experience and skills will include: A minimum of 5 years of professional experience building and operating large-scale, distributed systems in production. Strong software engineering fundamentals and proficiency in our primary languages (we use JVM languages like Kotlin and Java, as well as Ruby). Deep experience with cloud infrastructure (AWS preferred) and operating services in an API-driven, virtualized environment. Deep understanding of container orchestration with Kubernetes (EKS), specifically around resource management, scheduling, and autoscaling patterns. Strong background in Observability (e.g., Datadog, CloudWatch) to diagnose bottlenecks and drive data-driven decisions. Excellent communication and collaboration skills, with the ability to work effectively across time zones and language barriers. A proven ability to work both independently and collaboratively as part of a high-performing team. We would be thrilled if you had: Experience working in highly distributed teams, across large time zone differences. A deep understanding of the common failure modes in complex, distributed systems and experience conducting Root Cause Analysis (RCA). Proven track record of optimizing cloud infrastructure costs (FinOps mindset). Are a student of complex systems theory and how to build resilient and adaptive systems. An interest in or experience with applying GenAI/LLMs to improve developer productivity.
