Software Engineer, Infrastructure

Topsort is hiring a Software Engineer for our Infrastructure team to build and own the systems that power our real-time auction engine, API platform, and internal developer tooling. We're a fast-growing, global-first team of ~100 people looking for someone to join our mission to democratize auction-based ad technology.

Requirements

• Own the platform - Design, build, and maintain the foundational infrastructure that every Topsort product and engineering team depends on, from compute and networking to deployment and observability.
• Raise reliability - Define and enforce SLOs, build alerting systems that catch issues before customers do, and lead postmortems that actually prevent recurrence.
• Make deployments boring - Build CI/CD pipelines and deployment systems that are so reliable they're invisible. Automate the toil out of every release.
• Manage infrastructure as code - Own our cloud infrastructure (AWS/GCP) through Terraform or equivalent — no snowflake servers, no manual configuration drift.
• Enable developers - Build internal tooling and platform capabilities that make every Topsort engineer faster, safer, and more autonomous. Your customers are your colleagues.
• Harden security - Implement and enforce security best practices at the infrastructure level — secrets management, network policies, RBAC, supply chain integrity.
• Scale proactively - Capacity plan, load test, and tune our systems ahead of demand — not in reaction to a page at 2am.
• Participate in on-call - We take production seriously. You'll join the on-call rotation and be expected to respond, resolve, and document.
