DevSecOps Engineer

Momnt is an expanding financial technology company specialising in embedded lending and point-of-need consumer financing based in Sandy Springs, GA. We are transforming how merchants provide financing to their customers with our embedded lending platform. Our platform delivers a seamless digital experience that makes financing simple, fast, and affordable, connecting high-quality lenders with merchants, primarily in the home improvement sector, to empower consumers to pay for the things they need.

We’re looking for a hands-on DevSecOps Engineer with deep AWS experience, strong AWS CDK skills, and practical experience securing CI/CD pipelines using GitHub Actions. This person should be comfortable working across AWS infrastructure, Kubernetes, IAM, networking, CI/CD security, Trivy, SAST, DAST, Datadog, automation, monitoring, incident response, and compliance.

Our infrastructure is currently managed through AWS CDK, so strong hands-on experience with CDK is required. Terraform experience is also strongly preferred, as Momnt may use Terraform for future infrastructure projects.

In a company our size, you won’t just advise from the sidelines. You will be directly involved in building, securing, automating, and improving the systems that support our platform. You’ll own key parts of our infrastructure security posture, cloud environments, CI/CD security, and compliance readiness while working closely with engineering leadership and developers.

If you want a role where you can see the direct impact of your work, have genuine autonomy, and help shape the security culture of a regulated fintech from the ground up, this is it.

• Maintain encryption-at-rest, encryption-in-transit, data residency, and key management standards.
