WHAT WE DO MATTERS:

At The Knot Worldwide, we champion celebration - and that starts with celebrating our people. Our employees are passionate dreamers, thoughtful doers, and lifelong learners who power meaningful moments for millions around the world. We’re united by authentic connection, shared purpose, and a deep commitment to the global community we serve. Here, flexibility and belonging go hand in hand with high performance. Driven by our core values, we believe the best ideas come from empowered teams: those who consistently collaborate with intention to design solutions, spark ideas, and drive impact. Our people are at the heart of our success.

ABOUT THE ROLE AND OUR TEAM:

The Knot Worldwide is looking for a highly motivated, full-stack Senior Software Engineer with a passion for delivering value to the business, while helping to ensure that engineering best practices are adopted and followed.

• Provide mentorship to all members of the team, coaching team members on their personal and career development.

• Proven ability to design, build, and maintain scalable APIs and distributed systems
• Experience with one or more Node.js web frameworks (Nest.js, Express, Hapi.js)
• Understanding of eventual consistency, message queuing (RabbitMQ, SNS/SQS), and event-driven architectures
• Strong sense of software design patterns, anti-patterns, and testing practices (TDD, BDD)
• Hands-on experience deploying, operating and monitoring applications on the cloud (AWS)
• Proficiency with containerization and orchestration (Docker; Kubernetes familiarity preferred)
• Experience with CI/CD tools and workflows (GitHub, Jenkins or similar)
