About The Position

Grand Circle Corporation is the leader in international travel, adventure and discovery for Americans aged 50+. Headquartered in Boston, MA, our global travel brands include Grand Circle Travel, Overseas Adventure Travel and Grand Circle Cruise Line. We’re looking for a Sr. Software Engineer to join our Core Services team, a platform-focused group responsible for building and modernizing the services that power experiences across our websites, mobile applications and other customer-facing platforms. This is a highly hands-on role for someone who enjoys solving complex problems, asking thoughtful questions and figuring out how to build things better—not just maintain the status quo. You’ll spend the majority of your time coding while also taking technical ownership of projects, contributing to architecture and solution design, and helping shape the future of our platforms through modern, cloud-based, microservice architecture.

Requirements

5–8+ years of hands-on software engineering experience, with strong experience building backend applications, APIs and services.
Strong backend development experience in .NET/C# or another modern backend language (Java, JavaScript/TypeScript, Python, etc.).
Experience designing and developing microservices, RESTful APIs and cloud-based services.
Strong understanding of software architecture, design patterns, SOLID principles, automated testing and engineering best practices.
Experience designing scalable, performant, secure and maintainable solutions.
Experience with Azure or another major cloud platform; deep Azure expertise is a plus but not required.
Comfortable working across unfamiliar technologies and learning new tools and frameworks as needed.
Strong problem-solving skills and intellectual curiosity—you’re someone who asks “why?”, asks good questions and can independently figure things out.
Ability to take technical ownership and drive projects forward with a high degree of autonomy.
Experience with relational databases and SQL.
Experience with Git-based development workflows, code reviews and CI/CD practices.
Strong communication and collaboration skills, with the ability to work effectively across engineering and business teams.
Bachelor's degree in computer science, related discipline, or equivalent experience.

Nice To Haves

Experience modernizing or migrating legacy applications to microservice or cloud-based architectures.
Experience building shared platform services consumed by multiple applications or teams.
Experience with reservation, booking, customer/account services or other high-volume transactional systems.
Experience with telephony, call center or customer service integrations.
Experience serving as a technical lead or leading significant engineering projects.
Interest in eventually growing into an engineering leadership/management role.

Responsibilities

Take hands-on ownership of the end-to-end development of backend services and APIs, from requirements and technical design through development, testing, deployment and ongoing support.
Design and build scalable, secure, reusable and maintainable microservices that can be leveraged across our websites, mobile applications and other platforms.
Help modernize legacy capabilities by migrating functionality to a more flexible, cloud-based services architecture.
Drive technical projects from concept through delivery, partnering with engineers, product/business stakeholders and other technical teams.
Contribute to architecture and technical design decisions, challenging assumptions and asking the right questions to ensure we’re building an improved platform—not simply keeping existing systems running.
Develop high-quality, well-tested code and participate in code reviews, technical sizing and solution design.
Build and improve APIs and integrations supporting core capabilities such as reservations, booking, account services and customer-facing platforms.
Help evolve our engineering practices, architecture and technical roadmap to enable GCC to deliver new functionality faster and more effectively.
Support production applications and services through monitoring, troubleshooting, incident response and continuous reliability improvements.
Mentor and provide technical guidance to other engineers while collaborating with teammates locally and around the globe.
Work with Azure and modern cloud technologies to develop and deploy highly available services.
