Mercury is a fintech company that provides banking and financial software for businesses. As a Martech Lead, you will serve as a hands-on individual contributor responsible for the infrastructure and integrations that power the growth marketing team. Your day-to-day work involves building and maintaining marketing data pipelines using tools like Segment and Polytomic, managing GA4 administration, and ensuring reliable conversion tracking across both browser and server-side environments. You will act as a bridge between the marketing, data, and engineering teams, translating business needs into technical implementations. This includes managing marketing tags, troubleshooting reporting discrepancies, and automating workflows through APIs and custom code. The role is well-suited for a professional with a strong technical background in marketing technology who can independently prioritize a roadmap, manage complex data integrations, and maintain the reliability of the marketing stack. You should be comfortable working in a collaborative environment where you will partner with data teams to implement attribution methodologies and work with web engineering to support SEO and experimentation initiatives.
In January 1983, a Sequential Prophet 600 and a Roland Jupiter 6 were connected at a trade show in Anaheim. They were synthesizers made by different companies, but pressing a key on one could produce a note on the other. It was the first public demonstration of MIDI, a way for electronic instruments to communicate. The music was still up to the person at the keyboard. MIDI history At Mercury, we like technology that gives people more room to create. We’re hiring a Marketing Technology Lead to build and maintain the connections behind our Growth Marketing team’s work: reliable conversion signals, audiences that stay current, and tools that make new ideas easier to try. As we build banking* and financial software for ambitious companies, you’ll help our marketers spend more time putting those ideas into practice. You’ll report to our Head of Growth Marketing in a hands-on individual contributor role, working closely with Performance Marketing, Lifecycle, SEO, Data, and Engineering. You’ll own marketing integrations and platform infrastructure, including implementation, deployment, monitoring, and maintenance. Our Data team owns the shared customer-data foundation, attribution methodology, and analytical models. Growth Engineering builds and maintains our GTM orchestration layer. You’ll partner with those teams to make their systems work effectively in marketing, using Mercury’s shared development tools and standards. * Mercury is a fintech company, not an FDIC-insured bank. Banking services provided through Choice Financial Group and Column N.A., Members FDIC. Here are some of the things that you’ll do: Own the marketing technology roadmap with Growth Marketing leaders, prioritizing work that improves data reliability, customer experience, and the team’s ability to launch and learn. Build and maintain marketing data pipelines using Segment and Polytomic. Make approved Snowflake attributes, audiences, and conversion signals usable in marketing platforms, and return marketing activity to our shared data systems. Own GA4 administration and ongoing improvements, including event configuration, custom dimensions, platform connections, and reporting setup. Keep the platform reliable and useful for Marketing. Build and maintain marketing tracking and advertising conversion integrations, including campaign tagging, cross-domain measurement, and browser- and server-side tracking. Investigate missing events, duplicate conversions, and reporting discrepancies, partnering with Engineering when fixes require changes to application code. Partner with Data to implement agreed measurement definitions and attribution settings across marketing platforms, including GA4 and Rockerbox. Build, test, deploy, and maintain marketing integrations and advanced automations using APIs, integration tools, and custom code. Own routine releases within an agreed scope, using Mercury’s approved development setup and partnering with Data and Engineering on changes to shared systems. Maintain website forms, marketing tags, and experimentation tools. Partner with SEO and Web Engineering on publishing automation, structured-data checks, and the technical setup for SEO and AI-search experiments. Monitor marketing integrations and resolve failures. Catch stale audiences and broken connections; establish clear testing, alerting, and recovery practices. Keep marketing platforms well maintained through thoughtful configuration, access management, vendor coordination, and documentation. Build reusable tools and help teammates use them effectively. There are lots of paths that could lead you to be successful in a role like this; we think the strongest candidates will have some of this experience: Experience owning marketing technology or related systems, with examples of independently prioritizing and delivering work across acquisition and lifecycle marketing, including customer engagement platforms. Strong SQL skills and hands-on experience building integrations with APIs, webhooks, and cloud data warehouses. You can write, test, debug, and deploy code using shared development tools and review practices. Hands-on experience administering GA4 and maintaining advertising conversion integrations, including browser- and server-side tracking and audience syncs. You understand how identity, permissions, and data quality affect measurement and campaign execution. A track record of operating systems after launch. You know how to monitor failures, investigate unexpected results, recover from problems, and prevent them from recurring. Clear communication and sound judgment. You can turn a marketer’s goal into technical requirements, work through tradeoffs with Data and Engineering, and explain your decisions in plain English. Our current stack includes Snowflake, Segment, Polytomic, Customer.io, Salesforce, Dato, GA4, Rockerbox, and major search and social advertising platforms. Experience with these tools or comparable systems is valuable; we don’t expect you to
