About The Position

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. You will be responsible for providing technical expertise and mentorship to the team—working on complex and challenging user problems alongside other driven and talented engineers. This role drives our MarTech strategy, focusing on the development of scalable data infrastructure and the integration of cross-functional platforms. You will be responsible for ensuring a unified user experience by bridging data gaps across multiple digital ecosystems. Previous experience working with Customer Experience Platforms, Customer Data Platforms, Behavioural Analytics Platforms and Mobile Measurement Partners are helpful but not essential. The ability to think in systems and work with other teams is more important. We work in small, agile teams that move fast, so you will be building and owning all aspects of the systems, including infrastructure, data, APIs, and implementation. As a member of this team, you’ll be actively involved in implementing and delivering services in an iterative, agile fashion. You'll be working with our marketing and product teams at all stages of the SDLC to ensure we’re delivering the critical services the business requires to achieve key business objectives. If you are interested in building MarTech infrastructure; providing performant and scalable APIs and services; and making complex integrations smooth, intuitive, and observable, we would love to speak with you.
