Original job description

job summary:

Randstad is seeking a Senior Full Stack Engineer to join our high-impact client team in the Washington, D.C. metro area, supporting mission-critical enterprise operations applications. In this role, you will be the core technical driver behind high-throughput backend services and modern web interfaces, with work weighted approximately 75-80% toward backend distributed architecture (Java 17/21, Spring Boot, Apache Kafka, PostgreSQL) and 20-25% toward responsive frontend features in Angular. You will design fault-tolerant microservices, implement event-driven architectures, streamline CI/CD pipelines on AWS, and deliver intuitive tools that optimize operational workflows across the organization.

location: Washington, Washington, D.C. job type: Contract work hours: 9am to 5pm education: Bachelors

responsibilities:

Backend & API Development: Design, build, and maintain high-performance Spring Boot microservices (Java 17/21) exposing robust REST and reactive endpoints.

Event-Driven Architecture: Architect messaging pipelines using Spring Kafka, handling message ordering, retries, dead-letter topics (DLTs), idempotency, and schema evolution over time.

Data Modeling & Batch Workloads: Model, query, and optimize relational data using Spring Data JPA, Hibernate, and PostgreSQL, and engineer complex background data jobs with Spring Batch.

System Resilience & Security: Implement circuit breakers, rate limiting, and fallback patterns using Resilience4j; enforce enterprise security standards with Spring Security, OAuth2, JWT, and AWS Secrets Manager.

Frontend Delivery: Build and maintain performant, accessible UI features using Angular (v15+), TypeScript, and RxJS (accounting for ~20-25% of development time).

Testing & Quality Assurance: Write unit and integration suites using JUnit 5 and Spring Boot Test, while collaborating on automated end-to-end testing with Playwright.

DevOps & Cloud Ownership: Containerize microservices using Docker, configure automated CI/CD workflows via GitHub Actions and AWS CodeBuild, and manage cloud workloads in AWS.

Technical Leadership: Conduct rigorous architecture and code reviews, establish engineering standards, mentor junior developers, and assist in production incident resolution.

qualifications:

Professional Experience: 5+ years of production experience in backend software engineering with a demonstrable secondary focus in modern frontend development.

Core Backend Stack: Deep proficiency with Java (17 or 21), the Spring ecosystem (Spring Boot, Spring Security, Spring Data), and relational databases (PostgreSQL).

Messaging & Streaming: Hands-on experience developing event-driven systems using Apache Kafka or AWS MSK, including practical handling of DLTs, idempotency, and consumer group rebalancing.

Frontend Competence: Practical experience building single-page applications with Angular (v15+), TypeScript, RxJS, and modern CSS/UI libraries (Tailwind CSS, PrimeNG, or Angular Material).

Resilience & Testing: Proven background implementing fault-tolerance patterns (Resilience4j) and writing comprehensive automated tests (JUnit 5, Spring Boot Test).

Cloud & Containers: Experience deploying containerized workloads (Docker) within AWS environments using standard CI/CD tools (GitHub Actions, CodeBuild).

Education: Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline, or equivalent practical industry experience.

Equal Opportunity Employer: Race, Color, Religion, Sex, Sexual Orientation, Gender Identity, National Origin, Age, Genetic Information, Disability, Protected Veteran Status, or any other legally protected group status.
