Senior Platform Engineer - Astra

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. 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 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
• Experience operating in a startup or small-team environment where you own meaningful infrastructure surface area
• 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
• 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

Technical Skills

• 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)
• Experience designing and maintaining internal APIs and service abstractions used by other engineers
• Familiarity with observability tooling (e.g., Datadog, Grafana/Prometheus, OpenTelemetry)
• Understanding of secrets management, access control, and secure-by-default infrastructure patterns

Preferred Experience

• Prior experience in fintech, payments, banking-as-a-service, or another regulated industry
• Experience building platform tooling that supports compliance requirements (e.g., audit logging, data retention, access controls)
• Experience with GCP specifically, and with cross-cloud (GCP/AWS) infrastructure work
• Familiarity with database platform work in addition to application infrastructure
• Experience scaling internal platforms through a period of rapid engineering team or transaction growth

What We Offer

• Competitive compensation with equity in a growing fintech company
• Remote-first culture with flexible working arrangements
• Small team, big impact — your work directly supports Astra’s ability to scale responsibly
• Professional growth opportunities in compliance and risk management
• Mission-driven — build infrastructure that powers financial innovation while meeting the highest regulatory standards
