Momnt is an expanding financial technology company specializing 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.

The Lead Cloud & Platform Architect is responsible for designing, implementing, and directly operating the company's cloud and platform infrastructure. This is a true hands-on execution and leadership role that balances strategic cloud architecture with daily code deployment, platform ownership, SLAs, reliability, DR, security, and cost governance.

Our infrastructure is primarily managed through AWS CDK, so deep, hands-on expertise building and maintaining infrastructure with AWS CDK is strictly required. You won't just advise from the sidelines—you will actively build, secure, automate, and scale the systems supporting our platform while working closely with engineering leaders and developers.

Location:

Hybrid | Sandy Springs, GA OR Chicago, IL. Must be on-site in our Sandy Springs or Chicgo office a minimum of 2 days per week for direct team collaboration. Relocation assistance is not available.
Must be authorized to work in the U.S. (Sponsorship and Corp-to-Corp arrangements are not available).

Key Responsibilities as our Lead Cloud & Platform Architect, you will:

Architect and write infrastructure-as-code for scalable, secure, and cost-efficient AWS solutions across compute, storage, networking, and security.
Drive platform modernization (microservices, serverless, containers) using AWS CDK as the primary deployment framework.
Manage multi-account strategy, landing zone design, IAM governance, and network architecture.
Directly build, own, and maintain platform components, including CI/CD pipelines, shared services, deployment frameworks, and observability stacks.
Own platform SLAs, uptime targets, performance baselines, root cause analysis/post-mortems, and overall operational reliability.
Define, test, and maintain DR strategies, including failover design, RTO/RPO targets, and continuous DR testing cadences.
Implement and enforce platform security (IAM, secrets management, encryption, SOC2 controls) and manage cloud spending/optimization (FinOps).
Manage day-to-day AWS administration (VPCs, routing, backups, patching, CloudWatch/Datadog monitoring).

What Makes You a Great Fit

5+ years of hands-on experience in cloud engineering, platform engineering, or cloud architecture.
Strong hands-on mastery of AWS CDK (TypeScript, Python, or Java) to build and manage production infrastructure.
Deep technical expertise in AWS core services, VPC design, IAM, security, and multi-account strategies.
Practical experience working with ECS/EKS, AWS Lambda, EventBridge, and event-driven architectures.
Proven track record building CI/CD pipelines, automation frameworks, and internal platform tooling.
Demonstrated ability to directly own operational reliability, incident response, DR, and SLAs in a production environment.
Experience with Terraform is strongly preferred for potential future integration.

AWS Certified Solutions Architect – Professional.
Experience establishing internal developer platforms or "golden path" deployment patterns.
