About the Role

Marigold is looking for a Senior Full Stack Engineer to join the Campaign Monitor product team. In this role, you will work within an autonomous, multidisciplinary team alongside UX designers, Product Managers, and fellow engineers to build reliable customer experiences and develop systems that can support continued growth.

You will contribute across the software development lifecycle, from defining requirements and making architectural decisions to implementation, testing, deployment, and long-term maintenance. As a senior member of the team, you will help improve code quality through reviews and mentorship, make informed technical trade-offs, and take ownership of problems beyond the initial implementation.

The technology stack primarily includes C#, JavaScript, SQL, and Java. The team is also transitioning parts of its front end from Backbone.js to React, giving you the opportunity to contribute to both existing applications and newer development initiatives. The role includes participation in an on-call rotation to support the software you help build.

● Extend and improve existing product features while supporting new development initiatives.

● Participate in architecture discussions and help make technical decisions that support scalability, reliability, and maintainability.

● Review code, provide constructive feedback, and mentor other engineers to maintain high development standards.

● Use AI-assisted development tools to support coding, reviewing, and refactoring while applying independent judgment to design, correctness, and security.

● Make data-informed technical decisions and use instrumentation to understand application behavior and performance.

● Collaborate with Product Managers, UX designers, and engineers to clarify requirements, evaluate trade-offs, and deliver customer-focused solutions.

● Take ownership of software throughout its lifecycle, including ongoing maintenance and participation in the on-call rotation.

● Comfort using AI-assisted development tools such as GitHub Copilot, Claude Code, or Cursor to write, review, and refactor code.

● The ability to independently evaluate code quality, design decisions, correctness, and security when using AI development tools.

● Familiarity with different storage technologies, including SQL, Elasticsearch, Cassandra, and RDS offerings, and the ability to select suitable solutions for different use cases.

● Experience with data-driven decision-making and instrumentation techniques.

● Strong written and verbal communication skills, including the ability to document technical decisions and collaborate through interactive discussions.

● A collaborative approach to teamwork and a willingness to contribute to shared product and engineering goals.

Preferred Qualifications

● Experience with event-streaming architecture and stream processing technologies such as Kafka and Spark.
