Senior Mobile & Cloud Full-Stack Engineer
Job at JPS Tech Solutions – Senior Principal Mobile & Cloud Full-Stack Engineer role in DC area, hybrid schedule.
Job Description Randstad, 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 high-impact, hybrid role based in the DC area requires 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 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 (PI Planning) and maintaining camera‑on during virtual team collaboration.
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: 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 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: 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 & 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.
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 for critical SAFe ceremonies.
Benefits W2-Contract Only; C2C not considered for this role. Hybrid schedule; travel to DC for SAFe ceremonies.
