Senior Platform Engineer

Join Astra, the instant payments API revolutionizing money movement for fintech, banking, and marketplace products. As a Senior Platform Engineer, you will build and own core infrastructure and tooling, working hands-on across infrastructure-as-code, deploy tooling, and observability. You will partner directly with product engineers and operate independently on production infrastructure changes. This role offers remote options, a collaborative environment, and opportunities for professional growth.

• Construire et posséder l'infrastructure et les outils de base, y compris Terraform, CI/CD, et la provisionnement d'environnement.
• Collaborer directement avec les ingénieurs produits pour débloquer leur travail, en ne maintenant pas seulement l'infrastructure en isolation.
• Avancer notre fondation d'observabilité, y compris l'instrumentation des services restants et la construction de notre pipeline de collecte de métriques.

• 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
• Comfort operating independently on production infra (Terraform, IAM, CI/CD) without heavy review
• Track record of partnering closely with product engineering teams to unblock their work, not just maintaining infrastructure in isolation
• Direct experience with cloud infrastructure (GCP preferred, AWS or Azure also relevant) in production, including infrastructure-as-code
• Experience operating in a startup or small-team environment where you own meaningful infrastructure surface area and there isn't always a playbook
• Experience building or significantly maturing internal developer tooling, CI/CD systems, or service platforms, rather than only operating within an already-mature setup
• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience
• Experience designing and maintaining internal APIs and service abstractions used by other engineers
• Strong proficiency with infrastructure-as-code tools (e.g., Terraform, CloudFormation, Pulumi)
• Solid backend engineering skills in at least one production language (e.g., Go, Python, TypeScript/Node) for building internal services and tooling
• Experience with container orchestration (Kubernetes, ECS, or similar) and building CI/CD pipelines from the ground up
• 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
• Prior experience in fintech, payments, banking-as-a-service, or another regulated industry where infrastructure decisions carry real financial or compliance consequences
• Experience building platform tooling that supports compliance requirements (e.g., audit logging, data retention, access controls) alongside developer velocity
• Experience with GCP specifically, and with cross-cloud (GCP/AWS) infrastructure work
• Familiarity with database platform work (provisioning, migrations tooling, backup/replication strategy) in addition to application infrastructure
• Experience scaling internal platforms through a period of rapid engineering team or transaction growth
