Senior Software Engineer, Shared Services (New York)

Justworks combines HR software with human support to run payroll, benefits and compliance for small businesses. We’re helping businesses get off the ground by enabling them to focus on running their business. We solve HR issues.

Key responsibilities

• Harden the shared Temporal cluster for multi-tenant readiness — capacity modeling, namespace isolation, and admission control
• SLOs for Temporal-backed services, and alerting trustworthy enough that every page is worth waking someone for
• Build the golden paths and conventions that let other teams build workflows on the shared platform safely, with less hand-holding over time
• Enable multi-cluster availability, so tenant workloads keep running through a cluster or regional failure
• Own capacity and cost efficiency as the shared platform scales to more tenant teams and workflow volume
• Partner with tenant teams on workflow design, idempotency, and safe retry patterns as they onboard

Requirements

• 5+ years of professional software engineering experience
• 2+ years of hands-on, production experience operating self-hosted Temporal — running the cluster itself, not only writing workflows against one
• Experience operating a distributed system in production at scale — retries, idempotency, partial failure, and the datastores
• Operational depth in Temporal internals and cluster administration — how the cluster is configured, maintained, and tuned
• Experience securing and troubleshooting service-to-service communication between clients, workers, and the cluster
• Experience leading a technical migration or infrastructure consolidation across multiple stakeholder teams

Location and schedule

• Onsite in New York, New York
• Rotate on the shared platform's on-call schedule — incident response, root-causing production issues, writing postmortems, and continuously tuning alerts and SLOs
