Senior Software Engineer, Billing

Responsibilities

• Own and evolve the infrastructure supporting Billing Platform services: compute, storage, networking, CI/CD, and observability
• Design and maintain IaC (Terraform) for billing system infrastructure on AWS; contribute to module patterns and standards for the team
• Build and own observability systems — metrics, logging, alerting — with a focus on billing accuracy and payment reliability
• Implement deployment patterns and runbooks that work well in an AI-agent-assisted development workflow: clear rollback procedures, safe promotion gates, automated validation
• Partner with software engineers on service design — bringing infrastructure constraints and operational requirements into the conversation before code is written
• Identify systemic risks in the team's systems and drive improvements, including work that reaches into adjacent teams or services
• Participate in incident response for billing system issues. This role may require participation in an on-call rotation to provide support outside of standard business hours, including evenings, weekends, and holidays, as needed.
• Mentor engineers on the team; your technical judgment should help raise the bar for how the team builds and operates
