We launch high-impact digital platforms, modernize mission-critical systems, and create human-centered experiences that shape the way people live, work, and thrive.

We’re InRhythm. We build high-impact digital products that solve real-world problems at scale. Since 2002, we’ve helped modernize platforms and accelerate innovation for some of the world’s most recognized enterprises—including Goldman Sachs, Morgan Stanley, Mastercard, Fidelity, UnitedHealth Group, Amazon, to name a few.

We specialize in web, mobile, and cloud-native development—but what sets us apart is our culture of craftsmanship, velocity, and outcome-driven delivery. We don’t wait to be told what to do. We lead from within.

About the Role

We’re looking for a Lead Software Engineer with deep experience in distributed systems, cloud-native architectures, and enterprise-grade Java platforms. In this role, you'll architect and deliver mission-critical software built on a foundation of Microservices, Event-Driven Architecture, and Zero Trust principles. This is an opportunity to lead a team of seasoned engineers, collaborate across functions, and shape the future of platforms used by millions. If you’re driven by clean design, secure systems, and building what lasts—this is your moment.

Responsibilities

  • Design and implement distributed systems using Java Spring Boot, REST APIs, and cloud-native tooling
  • Architect microservices that are resilient, scalable, and fault-tolerant using Kafka or RabbitMQ for messaging
  • Define and enforce patterns for Event Sourcing and Command Query Responsibility Segregation (CQRS)
  • Collaborate with product and engineering teams to translate business requirements into scalable system designs
  • Ensure infrastructure and application layers conform to Zero Trust principles and enterprise security models
  • Deploy and manage containers using Kubernetes, and orchestrate APIs via API Gateways (Kong or similar)
  • Work with data teams to model and manage schemas on Oracle and integrate with existing enterprise systems
  • Establish best practices for identity and access management (IAM) across service boundaries
  • Lead design reviews, mentor engineering teams, and set technical direction across multiple workstreams
  • Serve as a thought leader and trusted advisor in architecture discussions, contributing to internal playbooks and knowledge sharing.

Qualifications

  • 8+ years of experience in software engineering with expertise in Java Spring Boot and cloud-native design
  • Proven experience architecting large-scale, event-driven systems with Kafka, RabbitMQ, or similar technologies
  • Deep knowledge of Microservices, CQRS, and Event Sourcing in production environments
  • Experience implementing Zero Trust Architecture across application, API, and data layers
  • Hands-on experience with container orchestration using Kubernetes
  • Strong command of API Gateway platforms such as Kong, Apigee, or similar
  • Experience working with Oracle or other enterprise-grade relational databases
  • Familiarity with IAM protocols and secure service communication standards (OAuth2, OpenID Connect, etc.)
  • Ability to lead complex system designs, mentor developers, and influence architecture across domains
  • A strong consulting mindset—collaborative, outcome-driven, and client-facing when needed.

Required Skills

  • Experience in software engineering with expertise in Java Spring Boot and cloud-native design
