Your Team Responsibilities

At MSCI, technology powers our global insights. We’re building the next-generation platform that enables our products and clients to move faster, integrate smarter, and scale securely.

As a Senior Technical Lead, you’ll play a pivotal role in designing and delivering new platform capabilities built on modern microservices, cloud infrastructure, and AI-assisted solutions. You’ll work with emerging technologies like the Model Context Protocol (MCP) to enhance how services interact with AI models and automate integration flows.

You’ll lead through hands-on engineering — writing code, guiding design, and mentoring others — while shaping the evolution of MSCI’s secure, intelligent, and scalable platform ecosystem.

Join us to build the foundation for MSCI’s AI-enabled future.

Your Key Responsibilities

At MSCI, we’re re-engineering our technology foundations to enable AI-driven innovation, seamless integrations, and secure scalability across our global platforms.

We’re seeking a Senior Technical Lead who combines deep engineering expertise with architectural vision to help drive this transformation. You’ll design and deliver microservices and APIs that power next-generation platform capabilities — including AI-assisted workflows, automated integration patterns, and model interaction layers built with the Model Context Protocol (MCP).

This is a hands-on leadership role, ideal for an engineer who thrives at the intersection of cloud infrastructure, intelligent automation, and modern application design.

Architect and build scalable, secure microservices in Go, Node.js, or Java, powering new platform and AI integration capabilities.
Design and deliver cloud-native services that leverage AI models and context-aware APIs to improve system intelligence and automation.
Collaborate globally with product, architecture, and AI teams to identify opportunities for embedding intelligence into the platform’s design.
Integrate modern protocols like MCP (Model Context Protocol) to enable richer AI context sharing and dynamic system behavior.
Mentor and coach engineers, driving excellence in code quality, architecture, and delivery.
Lead end-to-end delivery — from design through deployment — ensuring scalability, resilience, and observability.
Champion secure and policy-driven architecture, leveraging SSO federation, OAuth2/OpenID Connect, and Open Policy Agent (OPA).

Your skills and experience that will help you excel

10–15 years of backend or platform engineering experience.
Proven experience building and deploying microservices in production within a cloud environment (AWS, Azure, or GCP).
Expertise in Go, Node.js, or Java, with deep understanding of distributed systems and API design.
Experience integrating or leveraging AI/ML models or services within production systems.
Familiarity with AI-assisted development tools and a strong belief in data-driven, intelligent engineering.
Experience with Kubernetes, Docker, and CI/CD pipelines.
Exceptional communication and collaboration skills with a track record of technical mentorship.

Preferred Qualification:

Familiarity with Model Context Protocol (MCP) or similar frameworks for AI-context sharing.
Understanding of authentication and federation standards (OAuth2, OpenID Connect, SAML).
Experience with Open Policy Agent (OPA) or other policy-as-code models.
Exposure to vendor API ecosystems and secure platform integrations.
Passion for using AI to augment engineering processes and platform intelligence.
