As a Software Engineer - Sr. Consultant at Visa, you'll design and implement APIs between our backend services and mobile SDK, creating a robust connection for customer payments. You'll work closely with infrastructure engineers using Terraform to address service needs and implement comprehensive monitoring for those services. Your role will also require you to suggest enhancements to backend and mobile architectures and mentor fellow engineers through technical challenges, ensuring that the team delivers exceptional results.

To qualify for the Software Engineer - Sr. Consultant position at Visa, you should have at least 8 years of relevant work experience, ideally with a Bachelor’s Degree. Alternatively, 5 years of experience with an advanced degree or 2 years with a PhD can suffice. Preferred candidates will possess 9+ years of experience and have a deep understanding of Java, microservices, and cloud technologies like AWS along with a solid grasp of CI/CD practices.

Key essential skills for the Software Engineer - Sr. Consultant role at Visa include mastering Java and RESTful web services, along with experience in microservice architecture. Familiarity with Java 11, Spring Boot, Docker, Kubernetes, and the application development lifecycle is also critical. Moreover, your understanding of clean code principles and your ability to implement TDD/BDD practices will be crucial for maintaining high-quality code.

The hybrid work model for the Software Engineer - Sr. Consultant at Visa is designed to balance collaboration and flexibility. Employees are expected to work from the office three days a week, as decided by leadership, which helps foster team relationships and allows for direct engagement. The remaining days can be worked remotely, making it easier to maintain a work-life balance while still being a vital part of the Visa team.

Preparing for your interview as a Software Engineer - Sr. Consultant at Visa involves brushing up on your technical skills in Java, RESTful services, and microservices. Be ready to discuss your experience with CI/CD pipelines and clean code principles. Additionally, ensure you have examples ready that showcase your problem-solving abilities and leadership in complex technical projects. Finally, understanding Visa’s values and mission will help you convey your commitment to the company's goals.

When discussing your experience with Java and microservices architecture, articulate specific projects where you used Java effectively. Highlight your understanding of microservices design principles and how you implemented API interactions, ensuring to mention any frameworks or tools (like Spring Boot) you utilized.

To ensure code quality and maintainability, I apply clean code principles such as SOLID, DRY, and KISS. I utilize unit testing and TDD practices to catch issues early and create maintainable code. Sharing code reviews and best practices within the team also fosters a culture of quality.

Mentoring junior engineers involves being approachable and patient. I prioritize providing guidance through code reviews, sharing resources, and conducting knowledge-sharing sessions. By encouraging open communication, I help them grow technically and build their confidence in the work we do.

Absolutely! One significant technical challenge I faced was optimizing a high-load API that frequently faced performance issues. I analyzed the bottlenecks, refactored critical sections of the code, and implemented caching strategies, resulting in a performance improvement of over 50%. This not only improved efficiency but also enhanced user satisfaction.

For monitoring and alerting, I favor using industry-standard tools like Prometheus and Grafana to visualize system performance. I establish clear metrics and thresholds to trigger alerts, allowing the team to act quickly to any anomalies or system degradation, thereby minimizing downtime.

I stay updated by following relevant tech blogs, joining online forums, and attending workshops or webinars. Continuous learning is crucial in software engineering, so I also set aside time for personal projects to experiment with new frameworks, languages, and tools.

My experience with CI/CD practices includes setting up automated pipelines using tools like Jenkins and GitLab CI. I ensure that every change is built, tested, and deployed incrementally, which significantly reduces the time between code changes and production deployment, improving overall software delivery.

I have utilized Terraform to provision and manage our cloud infrastructure. By defining our infrastructure as code, it allowed for consistent deployment and management across environments. This method not only simplified the scaling process but also enhanced collaboration with other teams.

Feedback is invaluable in my development process. Regular feedback loops from code reviews and team retrospectives help me identify areas for improvement and guide my growth. I also seek feedback from stakeholders to ensure alignment with project expectations and requirements.

I am excited about the prospect of working at Visa because of its commitment to innovation in the payments industry and its global impact. I admire Visa's values and would love to contribute to a company that focuses on creating secure and reliable payment solutions while embracing technology. My skills align well with the role, and I am eager to collaborate with talented individuals who share a mission of upliftment and progress.
