Original job description

Position Summary

We’re hiring a Senior Backend Developer to build and maintain the services, APIs, and integrations behind our enterprise-grade applications. This is a hands-on development role: you’ll write Java and Spring Boot code every day, design APIs and data models, and work closely with your Team Lead, frontend developers, and cross-functional partners to deliver secure, reliable solutions. You’ll also bring strong, practical AI skills, using AI coding assistants and agents every day to design, build, test, and ship. It’s a great fit for a developer who thrives in fast-paced, agile environments and enjoys learning from and helping teammates.

Essential Functions and Responsibilities

Design, build, and maintain backend services and APIs using Java and Spring Boot.
Work hands-on with AI coding assistants and agents in your daily development, from implementation through testing, code review, and debugging.
Build and integrate RESTful and SOAP-based services, including modern authentication (SAML, PingFederate).
Design data models and write efficient queries across relational and NoSQL databases.
Build on AWS services such as EC2, S3, SNS, Secrets Manager, and Cognito.
Write automated unit and integration tests for the functionality you develop.
Document and test APIs using Postman and Swagger.
Turn business requirements into clean, secure, and maintainable code.
Troubleshoot and resolve issues across development, staging, and production.
Contribute to code reviews, technical design discussions, and team best practices, including how the team uses AI tools.
Collaborate with your Team Lead, frontend developers, and cross-functional teams to deliver on commitments.

What success looks like

Delivery: you consistently ship well-tested services and features that meet requirements and land on time
Code quality: your code is clean, secure, and maintainable, and holds up well in code review
AI-assisted development: you use AI coding tools and agents effectively and safely, and share what works with the team
API quality: the APIs you build are well designed, documented, and tested through Postman and Swagger, and easy for frontend and integration partners to consume
Performance and reliability: your services and queries perform well and hold up under real-world load
Testing: automated unit and integration tests cover the functionality you build
Stability: you help identify and resolve issues across development, staging, and production

Required Skills, Education, and Experience

A Bachelor’s degree in Computer Science, Engineering, or a related field
At least 5 years of experience in backend application development
Strong, hands-on use of AI in software development: coding assistants and agents (e.g. Claude Code, GitHub Copilot, Cursor), agentic workflows, and AI-assisted testing, debugging, and code review. You should be able to demonstrate this live, with real examples of how it has made you more effective
Good judgment on AI output: knowing when to trust it, how to verify it, and how to keep code quality, security, and maintainability high
Strong proficiency in Java and the Spring / Spring Boot framework
Experience designing and building REST, JSON, GraphQL, and SOAP APIs and integrations
Solid experience with databases such as PostgreSQL, MySQL, and DynamoDB, including data modeling and query performance
Hands-on experience with AWS, including EC2, S3, SNS, Secrets Manager, and Cognito
Experience with authentication and authorization, including protocols such as SAML and PingFederate
Experience with API design and testing (Postman, Swagger) and testing automation, including automated unit and integration tests
Experience with Git and CI/CD tools (e.g. Jenkins, GitHub Actions)
Good communication, problem-solving, and teamwork skills

Preferred Qualifications

Experience with Node.js.
Containerization with Docker.
DevOps tools and automation frameworks such as Ansible.
Knowledge of monitoring tools such as CloudWatch and Datadog.
Familiarity with a frontend framework such as Angular or React.

Experience with legacy-to-modern tech migrations.
AWS Developer certification.
