Modern Treasury is expanding deeper into money movement. We’re building new products that will let customers move funds across both traditional rails and emerging technologies, including stablecoins. You’ll help design, deploy and operate the infrastructure that makes this possible.

This is a hands-on devops role with strong ownership over infrastructure architecture and platform automation.

ABOUT THE ROLE

This role sits at the intersection of infrastructure, platform engineering and security. You’ll define how Modern Treasury scales and operates our infrastructure, and guide teams toward cohesive architectural patterns.

You will set direction and build for infrastructure systems that support:

• Ledger-backed transaction processing

• High-availability payment orchestration

This is a senior individual contributor role with broad influence across Product, Platform, and Infrastructure teams.

WHAT YOU’LL DO

• Lead architecture for AWS infrastructure, container orchestration, and CI/CD to support scalable payment systems

• Standardize automation and infrastructure-as-code to provision, scale, and operate high-volume ledger and transaction platforms

• Reduce operational overhead through tooling, streamlined workflows, and engineering standards uplift

• Optimize performance, reliability, and observability across real-time and rails-specific infrastructure

• Define service ownership and operational models, aligning platform and product teams on scalable rail architecture

• Contribute to infrastructure and security strategy for new payment rails, including FBO structures, stablecoin integrations, and compliance-focused features

WHAT YOU SHOULD HAVE

Required

• 8+ years in Devops, or infrastructure engineering

• Strong track record of setting technical direction without direct authority

• Experience building internal platforms that abstract complexity away from product teams

• Strong experience with:

• Designing and operating distributed systems

• AWS infrastructure at scale

• Infrastructure as Code (Terraform or similar)

• CI/CD systems and automation pipelines

• Containerized environments (Docker)

• Observability and performance tuning for production systems

• Experience with application and product security

• Experience scaling systems that process high-volume workloads

• Experience defining reliability standards and operational maturity models

What Sets You Apart

• Experience architecting infrastructure for multiple payment rails simultaneously

• Experience scaling systems that process high-volume financial or transactional workloads

• Understanding of payment rail mechanics (ACH, wires, RTP, cards, etc.)

• Familiarity with security and risk standards for money movement

• Ability to balance immediate delivery needs with long-term infrastructure strategy

TECHNOLOGIES WE USE

• Ruby on Rails for our backend

• React, GraphQL, and Tailwind CSS on the front end

• Postgres for our database

• AWS for infrastructure and hosting

• Docker for containerization

• GitHub for source code management

• Buildkite for continuous integration
