About The Position

Carta connects founders, investors, and limited partners through world-class software, purpose-built for everyone in venture capital, private equity and private credit. Carta's Fund Administration platform supports 9,000+ funds and SPVs, representing nearly $185B in assets under management, with tools designed to enhance the strategic impact of fund CFOs. Carta is shaping the future of private market infrastructure by creating the end-to-end ERP platform for private markets. This role is within the Developer Experience (DevEx) team, a lean "Special Ops" unit within Carta's Infrastructure organization. The team's goal is to remove friction from every step of the software delivery lifecycle so Carta's engineers can do the best work of their careers. They own CI/CD infrastructure, GitHub governance across 500+ repos, the rollout of AI coding tools, and the internal tooling layer. Carta is making a company-wide bet on AI-native development, and DevEx is the team defining how that happens.
