Senior Software Engineer II, Developer Experience

The Team You’ll Work With

You'll join our Developer Experience (DevEx) team, a lean "Special Ops" unit within Carta's Infrastructure organization. Our North Star: remove friction from every step of the software delivery lifecycle so Carta's engineers can do the best work of their careers.

We own CI/CD infrastructure, GitHub governance across 500+ repos, the rollout of AI coding tools across our company, and the internal tooling layer that lets Carta move fast without breaking things. We are systems thinkers who measure everything, because you can't optimize what you don't understand.

Carta is making a company-wide bet on AI-native development, and DevEx is the team defining how that happens. Six months from now, the playbook will be written. Now is when you get to write it.

The Problems You’ll Solve

As a Senior Software Engineer II on DevEx, you will:

• Build the MCP servers, agents, and plugin infrastructure that Carta's AI native development runs on, and define the patterns other engineers follow
• Design and ship agents purpose-built to solve specific developer problems across the software delivery lifecycle
• Architect and drive CI/CD pipelines that automate build, test, and deployment to accelerate delivery across R&D
• Build the infrastructure AI tooling runs on, so other engineers can build on top of it with confidence
• Mentor engineers and raise the technical bar through code reviews and architectural guidance

About You

• Experience: 8+ years in platform, backend, or fullstack engineering
• AI Builder: You've shipped production LLM systems, whether that's MCP servers or clients, AI extensions, connectors, or agents designed to solve real problems, not just demos
• Platform Mindset: You build things other engineers build on top of and think about APIs and developer ergonomics as seriously as performance
• Tech Stack: Python or Java; CI/CD tooling (CircleCI, GitHub Actions, ArgoCD, Jenkins, Docker); cloud-native (AWS, Terraform, Kubernetes); familiarity with secrets management tooling (Vault, Cloudsmith) is a plus
• Security Aware: You think about least-privilege, token lifecycle, and supply chain risks when designing developer tooling, not just after an incident
• Execution: You break down ambiguous problems and deliver with minimal guidance, bringing data to debates and owning outcomes end-to-end

Salary

Carta’s compensation package includes a market competitive salary, equity for all full time roles, exceptional benefits, and, for applicable roles, commissions plans. Our minimum cash compensation (salary + commission if applicable) range for this role is:

• $212,500 - $250,000 in Santa Clara, CA; San Francisco, CA; New York, NY
