# Senior Fullstack Engineer (W2, Agentic AI)

Job Purpose RWS runs hundreds of thousands of localization projects a year. Much of that work still depends on our operations teams reading signals, chasing status and making routine decisions by hand. We are building W2, our next-generation localization automation platform, and we want AI agents to take on part of that work so operations can scale without growing at the same pace. This is a greenfield initiative with a new team. Some agents will make recommendations while people keep the final decision. Others will run multi-step workflows on their own, inside boundaries we define and can audit. Your job is to make both kinds trustworthy enough that operations teams want to use them. You will work alongside two engineers as the team’s technical lead. You will own the architecture of the W2 agentic layer and make the final technical call, while writing a meaningful share of the production code and helping your colleagues make good decisions of their own. The team works with several other W2 teams, and the agent patterns, tools and guardrails you set will become the standard they build on. You will report to the Engineering Director and present technical direction to engineering lea
