Senior Infrastructure & Reliability Engineer

Platform Engineering Lead Stuut is transforming how B2B companies turn revenue into cash. Businesses worldwide have trillions tied up in receivables, yet the work between order and payment still relies on fragmented systems and labor-intensive manual processes. Stuut's AI agent works across order management, credit, collections, payments, cash application, disputes and deductions, carrying context through every step. Customers reduce DSO by 47%, collect 40% more cash and eliminate 70% of manual work without replacing their ERP. Stuut is already trusted by finance teams at companies including Honeywell, NCR and ZoomInfo, from Fortune 10 enterprises to scaling mid-market businesses. We are backed by a16z, Khosla Ventures, Activant, 1984 Ventures, Page One and Microsoft. The role: You'll own the platform engineering ships on. Most of the work is taking infrastructure that grew organically and making it reproducible, secure, observable and cheap to run. It's a small team with wide scope, real autonomy and broad access, so judgment matters as much as skill. This is a hands-on role with no direct reports. What you'll do: Put all infrastructure under version-controlled, reviewed code, including resources that were built by hand. Design a safe, auditable path from change to apply. Run and evolve our cloud networking across multiple clouds: address planning, private connectivity and secure engineer access to private resources. Operate production Kubernetes and the delivery pipeline around it: clusters, secrets, CI/CD, preview environments and build performance. Own observability and its cost. Make alerts meaningful, telemetry affordable and dashboards trustworthy. Drive security and compliance work to closure with evidence. Operate large production databases safely, including patching, failover, auditing and replication. Lead the infrastructure side of incidents and forensics. What we're looking for: You've done most of this before, not just contributed to it: 6+ years in infrastructure, DevOps, SRE or platform engineering, owning production systems end to end. Led infrastructure-as-code adoption or cleanup in an existing environment, including imports, drift and state problems. Run production Kubernetes and a multi-account cloud environment. Designed and debugged non-trivial cloud networks: peering, transit, VPN, overlapping ranges and private access. Operated mission-critical relational databases in production. Built or rebuilt an observability stack and brought its cost under control. Closed real security and compliance findings (SOC 2 or similar), with audit-worthy evidence. Nice to haves: Fintech or other regulated-industry experience; supporting enterprise or customer-hosted deployments; cost optimization at scale.
