About The Position

We’re looking for a Full Stack Engineer to join our AI Technology team and play a critical role in building and shaping the firm’s internal Generative AI platform. This is a high-impact, hands-on engineering position where you’ll contribute not just as a full stack specialist, but also as an AI strategist – helping to evolve our agentic AI platform powering the firm. You’ll work in a dynamic, fast-paced environment where product requirements evolve, and business stakeholders are deeply engaged. Your engineering skills, UX sensibility, and product mindset will all be utilized as you craft industry-leading UI platform and ecosystems. You’ll be a key contributor to the UI and backend of our agentic AI platform and associated tooling. You’ll help evolve our technical stack and development tools by contributing to architectural improvements, shared components, and implementation consistency across cross-functional teams. At the same time, you’ll work closely with product teams and business stakeholders, helping shape feature definitions, and designing and building high-impact UI solutions directly into our AI applications. Your development responsibilities will span full-stack, including web front-end, backend integration, API design, performance optimization, and system observability. You’ll also be involved in the team’s code quality and best practices, identify gaps in development lifecycles, and continuously improve both the core platform and how developers build with it.
