Job Description
About Us
At Office Ally, we've been revolutionizing healthcare administration since our inception. What started as a clearinghouse focused on simplifying insurance claims processing for healthcare providers has grown into a full-suite healthcare technology company. We offer a range of affordable, cloud-based revenue cycle management solutions –from eligibility verification and claims management to revenue recovery and payment processing –that help healthcare organizations of all sizes streamline operations and reduce administrative burdens so they can focus on what matters most: patient care.
In April 2026, Office Ally acquired Jopari Solutions, Inc, a leader in straight-through electronic claims processing for Property & Casualty (P&C), Commercial, and Government healthcare. Jopari brings deep industry expertise and innovative enterprise payment solutions that are transforming how disbursements are handled across the insurance ecosystem. Together, we are expanding our capabilities across the full healthcare transaction lifecycle, connecting claims, payments, and data exchange to deliver a more seamless and efficient experience for providers, payers, and partners.
At the core of our company are four key values that guide our mission and work:
- Ownership : We take pride in our responsibilities, driving results and taking accountability for the success of our projects.
- Empowerment : We believe in giving our team the autonomy and support to make decisions that lead to innovative solutions.
- Innovation : We continuously seek new and better ways to improve healthcare administration, embracing creativity and forward-thinking technology.
- Transparent Communication : Open, honest communication is at the heart of our collaborations, internally and with our clients, ensuring alignment and trust.
About the Role
This is an opportunity to join a growing company transforming healthcare technology through modern electronic billing, payments, and secure data exchange solutions across the Property & Casualty and Healthcare industries.
As a Senior Full Stack Development Engineer, you will play a key role in designing, building, and maintaining scalable applications and APIs that power mission-critical healthcare and insurance workflows. This role focuses on backend architecture, service development, data processing, and system integration, ensuring high performance, reliability, and maintainability across platforms. You will work across multiple initiatives, partnering with product, engineering, and implementation teams to deliver robust backend capabilities that support complex transaction processing and customer integrations. You will also leverage modern engineering practices, including AI-assisted development tools (Claude Code, GitHub Copilot) to improve development speed and efficiency, and apply modern testing approaches such as automated API and workflow validation (e.g., Playwright, where applicable) to ensure system reliability.
This role is central to building and maintaining the backend systems that power our core products and integrations. You will directly impact system scalability, reliability, and performance across multiple customer-facing and internal platforms. Your work will help ensure that complex healthcare and insurance transactions are processed accurately, efficiently, and securely at scale.
This is a hybrid role based in Concord, California, with an expectation of working in the office at least two days per week.
What You'll Do
- Design, develop, and maintain backend services, APIs, and core platform components
- Build scalable systems using Java and Spring Boot or similar frameworks
- Develop and support RESTful APIs and service integrations across internal and external systems
- Participate in system design and architecture discussions for scalable backend solutions
- Work closely with product, implementation, QA, and engineering teams to define technical requirements
- Support complex data processing, transformation, and integration workflows
- Ensure backend systems are secure, reliable, and performant under high transaction volumes
- Utilize Claude to support development, accelerate problem-solving, and improve productivity while maintaining high code quality.
- Contribute to CI/CD pipelines, deployment automation, and DevOps practices
- Write clean, maintainable, and testable code with strong unit and integration test coverage
- Apply modern engineering practices, including shift-left testing and continuous quality improvement
- Use AI-assisted development tools (Claude Code, Copilot, etc.) to accelerate development, debugging, and analysis
- Improve system observability through logging, monitoring, and diagnostics enhancements
- Troubleshoot production and integration issues as needed
What You'll Need
- Bachelor's degree or equivalent experience in Computer Science or related field
- 8+ years of backend software engineering experience
- Strong experience in Java and backend service development
- Solid understanding of RESTful APIs and distributed systems design
- Experience with Spring Boot or similar backend frameworks
- Strong SQL experience (Oracle preferred) and familiarity with NoSQL databases
- Experience working with cloud platforms (AWS, Azure, or GCP)
- Experience and passion around working with AI: Copilot, Claude, Windsurf, Gemini Code, or similar
- Experience with containerization (Docker) and orchestration (Kubernetes)
- Familiarity with CI/CD pipelines (Jenkins or similar tools)
- Deep understanding of Agile development methodologies
- Experience building maintainable, scalable backend systems
Nice to Have
- Experience in healthcare, insurance, or financial services systems
- Exposure to high-volume transaction processing or integration-heavy environments
- Experience with event-driven architectures or messaging systems (Kafka, RabbitMQ, etc.)
- Familiarity with Elastic Cloud
- Experience with API testing or workflow automation tools (Playwright, Postman, etc.)
- Knowledge of system observability tools (ELK, Prometheus, Datadog, Grafana, etc.)
- Strong debugging and production troubleshooting skills
- Experience working with sensitive data and compliance requirements (HIPAA / PHI / PII)
- Strong communication skills and ability to collaborate across technical and non-technical teams
