About the Role

As a Senior Software Engineer, Platform at Payabli, you'll own the infrastructure and developer experience that every engineer at the company builds on top of. You won't be handed a task list—you'll define the vision for how we build, test, deploy, and operate our platform on AWS, then execute against it.

What You'll Do

• Own the infrastructure: Design, build, and operate Payabli's cloud infrastructure, making architectural decisions around networking, compute, storage, and security.
• Build the deployment backbone: Own and evolve CI/CD pipelines end-to-end for fast, safe, and repeatable production deployments.
• Make local development exceptional: Ensure the local development experience mirrors production closely enough to catch real problems early.
• Enable AI-assisted development: Build environments that let engineers leverage AI coding agents and assistants safely within a PCI-compliant infrastructure.
• Define and drive the platform roadmap: Partner with engineering leadership to prioritize infrastructure investments.
• Harden everything: Handle PCI-DSS scoping, network segmentation, secrets management, access controls, and audit trails.
• Instrument and observe: Build the monitoring, alerting, and observability stack for real-time visibility into system health.
• Multiply the team: Document patterns, write runbooks, and establish infrastructure standards to make the organization more self-sufficient.

What We're Looking For

• 5+ years of professional infrastructure or platform engineering experience building and operating production AWS environments at scale.
• Deep AWS expertise (ECS/EKS, RDS, Lambda, VPC, IAM, CloudFormation/CDK/Terraform).
• Strong CI/CD experience using GitHub Actions, GitLab CI, Jenkins, or similar.
• Infrastructure-as-code fluency to define, version, and deploy infrastructure declaratively.
• Security-minded by default with a strong understanding of network segmentation, least-privilege access, and secrets management in financial environments.
• Proactive and opinionated mindset with strong communication skills.

Nice to Haves

• Prior experience in fintech, payments, or a PCI-DSS-regulated environment.
• Experience supporting or enabling AI/ML development workflows or LLM-based tooling.
• Familiarity with the .NET ecosystem on AWS.
• Experience building internal developer platforms.
• Background with observability stacks (Datadog, Grafana, CloudWatch, OpenTelemetry).
• Kubernetes experience, particularly EKS on AWS.

What We Offer

• Competitive salary
• Stock options
• Flexible PTO and paid parental leave
• Medical, dental, & vision insurance
• 401(k), HSA, and pre-tax savings programs
