Job description

Company Description:

pureIntegration is a digital engineering, consulting and professional services firm headquartered in the Washington, DC area, serving media, entertainment, and connectivity companies for more than 22 years. Our Ad Tech & Media practice helps advertising organizations modernize and operate the systems that power their revenue — spanning linear, addressable, programmatic, AVOD/FAST, and CTV ad delivery — including ad decisioning, order management, traffic and billing, data integration, and reporting across the order-to-cash lifecycle. 

Job Description:

We're looking for a Senior Backend Software Engineer with strong hands-on experience across both Java and Node.js to support backend and microservice development for our client. You'll work on REST APIs and distributed backend systems deployed in a cloud-native, containerized environment, collaborating closely with engineers, technical leads, and product managers across multiple teams.

This role requires someone who can move comfortably between Java/Spring and JavaScript/Node.js codebases, has a solid grounding in computer science fundamentals and distributed systems, and takes ownership of issues from identification through resolution with minimal supervision.

This is a full-time remote position. The annual base salary range is $120,000 – $140,000. Candidates will be paid within this range based on their work experience and skills. Candidates are also eligible for our full list of benefits linked here. 

Responsibilities

  • Design, develop, and maintain backend services and REST APIs using Java, Spring Framework/Spring Boot, and Node.js
  • Build and support containerized microservices deployed on AWS, including Kubernetes/EKS environments
  • Apply asynchronous, reactive, or functional programming patterns where appropriate across both Java and JavaScript codebases
  • Troubleshoot complex backend and distributed-system issues, performing root-cause analysis and driving fixes through to resolution
  • Work with Infrastructure as Code (Terraform preferred) and CI/CD pipelines (GitHub Actions, Concourse, Jenkins, or similar) to support deployment and delivery
  • Design and implement integrations with SQL and NoSQL databases
  • Participate in code reviews, sprint planning, technical discussions, and troubleshooting sessions
  • Proactively identify and escalate blockers, risks, and dependencies rather than waiting for others to surface them
  • Take ownership of production issues, coordinating resolution across internal and partner teams
  • Communicate technical issues, risks, and proposed solutions clearly to both technical and non-technical stakeholders
Qualifications:

Java / Backend Development

  • Strong hands-on Java experience with Spring Framework/Spring Boot
  • Experience designing REST APIs and backend microservices
  • Solid grasp of OOP, software design principles, and backend architecture
  • Familiarity with asynchronous, reactive, or functional programming
  • Ability to troubleshoot complex backend and distributed-system issues

JavaScript / Node.js

  • Hands-on Node.js backend experience, including async patterns and frameworks like Express.js
  • Comfortable working across both Java and Node.js codebases

Cloud / Infrastructure

  • Strong AWS experience (or comparable cloud platform)
  • Experience with containerized applications and Kubernetes (EKS preferred)
  • Familiarity with Terraform/IaC and CI/CD tools (GitHub Actions, Jenkins, or similar)
  • Comfortable in Linux environments

CS Fundamentals

  • Strong grounding in data structures/algorithms, concurrency, distributed systems, and system design
  • JVM and memory management fundamentals
  • Database fundamentals (SQL and NoSQL)

Communication & Ownership

  • Strong communicator across engineering, product, and cross-team stakeholders
  • Proactively surfaces blockers and risks rather than waiting to be asked
  • Owns issues end-to-end, including production incidents, with minimal supervision
