About this role
This role sits in the Business Growth organization and uses engineering, AI, and automation to address business problems directly. Working with the organization’s Chief of Staff, the GTM Engineer explores operational issues and implements solutions hands-on.
The team’s mission is to create a foundation for reviewing business strategy and performance and to build next-generation go-to-market processes using AI and data. Responsibilities include implementing agentic workflows in which multiple AI agents coordinate marketing tasks such as content generation, campaign optimization, and lead nurturing. The role also develops LLM-based automation for customer inquiries and troubleshooting so that people can focus on more advanced problem solving.
The position rapidly develops and validates prototypes that automate daily processes for Sales and other business teams, using APIs and various tools. It also involves independently researching, proposing, selecting, and introducing suitable AI tools, frameworks, and architectures. Building KPI foundations and data pipelines is part of the team’s work.
The stated environment includes Salesforce, Zapier, Google Apps Script, KARTE Datahub, BigQuery, Looker, various LLMs, and APIs. The posting places no fixed restriction on tools, technologies, or frameworks. Dify, LangChain, and CrewAI are specifically named as technologies the engineer may propose, introduce, and implement at their discretion.
The role supports go-to-market transformation around PLAID’s KARTE customer-experience platform, its behavioral data, and its real-time analysis technology. The reporting line is to the Business Growth Chief of Staff, and the role works closely with that person from planning through implementation. Prototypes receive rapid feedback from business teams and are refined in an agile manner as internal systems.
The position is based at the company headquarters in Ginza, Tokyo. The work arrangement combines office attendance and remote work. The posting states that business-side staff currently generally work from the office three days per week, while the company or team may request a certain number of office days depending on circumstances.
