Job Summary

in partnership with a major client is seeking a Senior Principal Mobile & Cloud Full-Stack Engineer to drive the design and development of next-generation mobile-first cloud-native applications for operational and passenger systems. This is a high-impact hybrid role based in the DC area requiring expertise across Native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) combined with robust skills in building Back-End for Front-End (BFF) microservices using Java/Spring Boot or NodeJS running on AWS ECS Fargate and Lambda. Operating within a SAFe Agile framework you will be crucial in defining architecture managing containerized services implementing CI/CD with tools like Bitrise and AWS CodePipeline and ensuring secure scalable data integration using Kafka/Kinesis Aurora PostgreSQL and DynamoDB. Candidates must be prepared for a hybrid schedule including travel to DC for key SAFe ceremonies (like PI Planning) and maintaining camera-on during virtual team collaboration to embrace agile self-management and self-organization.

Key Responsibilities

Native Mobile Development: Design and develop high-performance native applications for iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) including extensions for Apple Watch and Wear OS.
Security & Authentication: Implement integration with enterprise identity providers including AWS Cognito MSAL (Azure AD) and other SSO solutions.
Edge Computing & Offline-First: Build features leveraging peer-to-peer APIs indoor wayfinding (CoreLocation/ARKit) and on-device intelligence (BNNS/NNAPI) while optimizing for low-bandwidth and offline environments.
BFF Architecture: Architect and develop mobile-optimized BFF microservices using Spring Boot (Java 21) or NodeJS (22) deployed on AWS ECS Fargate.
Data Aggregation: Shape and aggregate data from multiple enterprise sources (MuleSoft Oracle SQL Server) into mobile-specific APIs using GraphQL REST or AppSync patterns.
Cloud Microservices: Develop and maintain event-driven and real-time workflows using AWS Lambda (NodeJS/Java) managing hybrid persistence with Aurora PostgreSQL DynamoDB and Redis.
Enterprise Integration: Implement routing transformation and integration logic using Apache Camel with messaging services like Kafka Kinesis SQS and SNS.
DevOps & CI/CD: Manage maintain and automate build/deployment pipelines using AWS CodeBuild/CodePipeline and Bitrise for native apps defining infrastructure using CloudFormation/CDK or Terraform.
Agile & SAFe Collaboration: Actively participate in all SAFe ceremonies (PI Planning retrospectives etc.) embrace self-management for iteration commitments and collaborate across Product Architecture and Middleware teams.
Monitoring & Observability: Design and implement secure observable and scalable cloud architectures using AWS CloudWatch/CloudTrail/X-Ray with preference for experience in Dynatrace.

Required Qualifications

Experience Level: 7 years in full-stack engineering with a strong focus on both native mobile and cloud backend development.
Languages & Frameworks: Expert-level proficiency in Swift Kotlin TypeScript Java 21 and SQL. Experience with SwiftUI Jetpack Compose Spring Boot and ExpressJS/NestJS.
Cloud Expertise (AWS Focus): Deep hands-on experience with core AWS services including ECS Fargate Lambda API Gateway Cognito SQS/SNS Kinesis Aurora PostgreSQL and DynamoDB.
Integration & Messaging: Practical experience with Apache Camel and stream processing/messaging via Kafka or AWS Kinesis.
DevOps & Infrastructure-as-Code (IaC): Proven ability to implement CI/CD for native apps (e.g. Bitrise AWS CodePipeline) and define cloud infrastructure using CloudFormation/CDK or Terraform.
Agile Proficiency: Demonstrable experience working in a SAFe or similar scaled Agile environment including capacity planning and self-organization.
Preferred Experience: Familiarity with Intune MDM enterprise mobility management and low-latency offline-first design patterns.
Soft Skills: Strategic mobile-first thinker; excellent communicator; detail-oriented; and highly collaborative within large multi-disciplinary teams.
Work Arrangement: Must be willing to work in a hybrid capacity and travel to the DC area on an as-needed basis particularly for critical SAFe ceremonies.
