[Remote] Principal Software Engineer, Group Tenant Scale at GitLab

Candidates must possess extensive experience in designing, developing, migrating, scaling, and operating large distributed systems within a SaaS environment. A proven track record of leading transformations from monolithic to distributed architectures, including Postgres sharding or other database partitioning strategies, is essential. Hands-on programming experience in Ruby and/or Go, along with expertise in service communication and observability at scale (e.g., service mesh/Istio, Kafka, tracing/metrics), is required. Principal-level technical leadership, including the ability to set strategy, influence across organizations, and mentor principal and senior engineers, is crucial. A balance of infrastructure depth and application architecture awareness, with a skill for making system-level tradeoffs that prioritize reliability and customer experience, is necessary. Excellent communication skills for explaining complex systems to both technical and non-technical audiences are also required.
