Senior Platform Engineer, Astra

• This role suits someone who's energized by building leverage for other engineers, comfortable owning meaningful infrastructure surface area, and motivated by the stakes of doing this well in a regulated, real-money environment
• 5+ years in a platform engineering, infrastructure engineering, or backend engineering role with significant infrastructure ownership
• Experience building or significantly maturing internal developer tooling, CI/CD systems, or service platforms, rather than only operating within an already-mature setup
• Experience operating in a startup or small-team environment where you own meaningful infrastructure surface area and there isn't always a playbook
• Direct experience with cloud infrastructure (GCP preferred, AWS or Azure also relevant) in production, including infrastructure-as-code
• Track record of partnering closely with product engineering teams to unblock their work, not just maintaining infrastructure in isolation
• Comfort operating independently on production infra (Terraform, IAM, CI/CD) without heavy review
• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience
• Strong proficiency with infrastructure-as-code tools (e.g., Terraform, CloudFormation, Pulumi)
• Experience with container orchestration (Kubernetes, ECS, or similar) and building CI/CD pipelines from the ground up
• Solid backend engineering skills in at least one production language (e.g., Go, Python, TypeScript/Node) for building internal services and tooling
• Experience designing and maintaining internal APIs and service abstractions used by other engineers
• Familiarity with observability tooling (e.g., Datadog, Grafana/Prometheus, OpenTelemetry) and how platform decisions affect reliability and debuggability
• Understanding of secrets management, access control, and secure-by-default infrastructure patterns

Desirable

• Astra is the instant payments API powering money movement for fintech, banking, and marketplace products
• Every transaction that runs through our systems is real money moving in real time, and the infrastructure underneath our product is what lets our engineering team ship quickly without breaking the systems that depend on it
• As a Platform Engineer at Astra, you'll build and own core infrastructure and tooling: Terraform, CI/CD, environment provisioning, and the abstractions engineers rely on to ship and run their own code
• You'll work hands-on across infrastructure-as-code, deploy tooling, and observability, partnering directly with product engineers rather than sitting behind a large platform org with layers of process
• Own pieces of core platform infrastructure, including the Terraform migration (VPC, IAM, networking), CI/CD pipelines, and environment provisioning, as part of a growing infrastructure team
• Build and maintain the tooling and abstractions that let product engineers ship and run their own code without solving infrastructure problems from scratch
• Advance our observability foundation, including remaining service instrumentation and building out our metrics collection pipeline
• Standardize monitoring and alerting, including business and financial operations metrics and synthetic monitoring
• Harden CI/CD pipelines, including secrets migration and building self-service deployment tooling
• Support GCP infrastructure work as our platform scales, including dead-letter queue handling and other reliability pieces of our messaging system
• Help build out compliance remediation tooling, local dev/onboarding tooling, GCP cost visibility, and infra architecture documentation as these needs are validated
• Operate independently on production infrastructure changes, since most of this work is scoped execution rather than architecture-setting
