Senior Platform Engineer

About the role

ABOUT ASTRA

Astra is building mission-critical infrastructure for moving money at scale. Our platform processes billions in annual transaction volume with 99.9%+ uptime, powering real-time transfers, bank debits, card disbursements, and complex financial compliance systems. We provide APIs and automation tools that enable businesses to move money programmatically while maintaining strict regulatory requirements.

THE ROLE

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. 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.

WHAT YOU’LL DO

- 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

WHAT WE’RE LOOKING FOR

Required Experience

- 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
