Principal Software Engineer (Java)

As a Principal Software Engineer, you'll contribute directly to embedding AI across workflows, including delivery, product, and strategy. You'll help accelerate client outcomes through our AI Accelerator and play a hands-on role in the evolution of tools like TestPilot AI, which uses natural language and generative intelligence to automate mobile and web testing.

You'll also have the opportunity to take part in client-facing AI workshops, where we explore real-world applications of generative AI and collaborative innovation. If you're excited by the power of applied AI, this is your platform to lead.

What You'll Do

As a Principal Software Engineer at InRhythm, you will:

• 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

Requirements

You'll bring:

• 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

Must have skills:

• Java, Spring Boot, Microservices, Kafka, CQRS, Event Sourcing and Zero Trust Architecture.
