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. From CI/CD pipelines and infrastructure-as-code to local development and Cloud/Agent development environments, you'll be the person who makes every other engineer faster, safer, and more productive.

This is a high-ownership role. We're looking for someone who sees a gap, builds a plan, and drives it forward—not someone who waits to be told what's next.

What You'll Do

Own the infrastructure. Design, build, and operate Payabli's cloud infrastructure. You'll make the architectural decisions around networking, compute, storage, and security that determine how our platform scales, performs, and stays resilient as transaction volume grows.

Build the deployment backbone. Own and evolve our CI/CD pipelines end-to-end. Every push to production should be fast, safe, and repeatable. You'll design the release process that lets engineers ship with confidence—automated testing, staged rollouts, rollback strategies, and deployment observability baked in.

Make local development exceptional. Engineers should be able to clone a repo and be productive in minutes, not days. You'll own the local development experience and make sure it mirrors production closely enough to catch real problems early.

Enable AI-assisted development. As the team adopts AI coding agents and assistants, you'll build the environments that let engineers leverage these tools safely and effectively within a PCI-compliant infrastructure.

Define and drive the platform roadmap. Assess where we are, define where we need to be, and build the plan to get there. You'll partner with engineering leadership to prioritize infrastructure investments and communicate the “why” behind them.

Harden everything. Infrastructure in payments means PCI-DSS scoping, network segmentation, secrets management, access controls, and audit trails are your daily work. You'll ensure our infrastructure posture keeps pace with compliance requirements as we scale.
