Title: Senior Mobile & Cloud Full-Stack Engineer
Location: Washington, DC(Onsite)
Our 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.
