Job description

The Company You’ll Join

Carta connects founders, investors, and limited partners through world‑class software, purpose‑built for everyone in venture capital, private equity and private credit. Trusted by 65,000+ companies in 160+ countries, Carta’s platform of software and services lays the groundwork so you can build, invest, and scale with confidence.

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. Recognized by Fortune, Forbes, Fast Company, Inc. and Great Places to Work, Carta is shaping the future of private market infrastructure.

Together, Carta is creating the end‑to‑end ERP platform for private markets. Traditional ERP solutions don’t work for Private Funds. Private capital markets need a comprehensive software solution to replace outdated spreadsheets and fragmented service providers. Carta’s software for the Office of the Fund CFO does just that – it’s a new category of software to make private markets look more like public markets – a connected ERP for private capital.

The Team You’ll Work With

The Frontend Platform team is the core infrastructure team that underpins the entire frontend experience at Carta. We maintain the systems, including our monorepo and other key FE repositories, that enable hundreds of engineers to build and ship high‑quality, modern frontend applications. Our mantra is: “Create a development experience that people will miss when they leave”. FEP drives platform‑level initiatives, sets best practices in frontend development, and elevates engineering velocity and experience across Carta, ensuring our applications reflect modern standards and scalable development techniques.

The Problems You’ll Solve

• Design, evolve, and maintain the frontend monorepo, ensuring scalable foundations for all Carta applications.
• Drive platform‑level improvements and engineering upgrades, including page performance, dependency management, and major React version migrations efforts—that positively impact the whole company, not just a single product.
• Steer the AI‑assisted development strategy for frontend applications, taking into account best practices.
• Develop and optimize build tooling (e.g., Rspack, Playwright), empowering frontend teams to deliver faster, more reliable releases.
• Foster best practices in frontend infrastructure, collaborating with engineers across Carta to ensure high‑quality, reusable platform solutions.

About You

We are seeking a highly experienced, platform‑focused frontend engineer ready to drive significant, company‑wide impact. You should be able to demonstrate a track record of solving complex scaling challenges in large engineering organizations.

• Extensive Monorepo Experience. You have deep, hands‑on experience working on and maintaining large‑scale frontend monorepos and developing the underlying tooling (e.g. Nx / Rush, pnpm, vite, storybook, eslint).
• Platform & Scale. You have previously worked on a dedicated platform or infrastructure team at a company with an engineering organization of 100+ engineers.
• Deep React Knowledge. You have a history of advanced contributions to a React‑based ecosystem. You are well versed in modern React development paradigms.
  Global Improvements. You have demonstrated leadership in driving platform‑level improvements that affect all applications, such as significant page performance gains, build time reduction, or dependency upgrade initiatives.
• Frontend DevOps. You possess a strong command of frontend build and delivery systems, including optimizing bundlers (Webpack/RSpack) and setting up/maintaining CI/CD pipelines (Github Actions, Jenkins, CircleCI).
• 7+ years of professional experience recommended in relevant frontend platform engineering roles.

The Interview Process

Carta follows a standard tech startup interview process, where you will meet with a recruiter and hiring manager first. We’ll then ask you to show off your skills with a real‑world take home exercise (we do not do LeetCode‑style interviews, no one will quiz you on writing a doubly‑linked list) and virtual interviews. During the process, you can ask questions to people across different parts of the Frontend Platform team to learn what kind of work we do and how it lines up with your interests.
