MSCI is building the next generation of large-scale, high-performance platforms that power critical financial risk and portfolio decisions for the world’s leading institutions. These systems process massive volumes of financial data, expose real-time analytics through service APIs, and increasingly incorporate AI-driven capabilities to improve insight, automation, and usability.

We are looking for a Senior Software Engineer who combines strong hands-on engineering with clear architectural thinking. This role is for someone who enjoys designing systems end-to-end, shaping technical direction, and building scalable services that must be correct, fast, and reliable — while also being excited to apply AI and intelligent automation in real production systems.

This is a senior, high-impact role with influence across services, architecture, and engineering practices.

• Design and evolve distributed systems that process and serve high-volume financial data with strict performance and reliability requirements.
• Own system architecture and design quality, ensuring solutions are scalable, fault-tolerant, observable, and maintainable.
• Build and operate containerized services running in Kubernetes, using service-oriented and microservices architectures.
• Collaborate with product managers, business analysts, and researchers to translate complex domain problems into clean technical designs.
• Drive technical decisions across teams—API design, data modeling, service boundaries, and integration patterns.
• Modernize systems by evolving monoliths toward service-based architectures where appropriate.
• Implement robust automated testing (unit, functional, performance) and contribute to CI/CD pipelines.
• Participate in production support (2nd tier) with an engineering mindset focused on prevention and system resilience.
• Actively contribute to MSCI’s North Star Architecture—our long-term technical vision for scalable, high-performance risk platforms—by influencing platform standards, shared infrastructure, and system design decisions.
• Explore and integrate AI-enabled system capabilities, including intelligent data processing or validation, AI-assisted analytics workflows, automation, optimization, and decision support embedded in backend services.

What We’re Looking For

Core Strengths

• Strong experience designing and building high-performance distributed systems.
• Excellent grasp of object-oriented design, system decomposition, and data structures.
• Proven ability to reason about architecture, not just implement tickets.
• Comfort working with large datasets and performance-sensitive systems.
• Clear, confident communication with both technical and non-technical partners.
• A strong sense of product ownership — you care about outcomes, not just code.

Technical Experience

• Significant experience with Java and JVM-based systems (Java, Scala, Akka, Spring, etc.).
• Service-oriented / microservices architectures.
• Spring Boot, REST/gRPC APIs.
• Linux/Unix environments.
• Build and dependency management (Maven / Gradle).
• CI/CD pipelines and modern DevOps practices.
• Profiling, performance tuning, and memory management in JVM systems.
• Version control and collaborative development in globally distributed teams.

Nice to Have

• Python experience (especially for data processing or AI-adjacent services).
• Kubernetes, Docker, and containerized deployments.
• Experience with cloud platforms (Azure preferred).
• Experience migrating or refactoring legacy systems.
• Familiarity with financial instruments, risk, or portfolio analytics.
• Exposure to AI/ML systems in production (you don’t need to be a data scientist).

What Makes This Role Different

• Architecture is not theoretical here—you’ll design it and build it.
• You’ll have room to shape how AI is applied in real backend systems at scale.
• The team values strong opinions, collaborative problem-solving, and engineers who take responsibility for the whole system.

What we offer you

• Salary range: $138,000 - $179,000 / year plus eligible for annual bonus
• Transparent compensation schemes and comprehensive employee benefits, tailored to your location, ensuring your financial security, health, and overall wellbeing.

• Flexible working arrangements, advanced technology, and collaborative workspaces.

• A culture of high performance and innovation where we experiment with new ideas and take responsibility for achieving results.

• A global network of talented colleagues, who inspire, support, and share their expertise to innovate and deliver for our clients.

• Global Orientation program to kickstart your journey, followed by access to our Learning@MSCI platform, AI Learning Center , LinkedIn Learning Pro and tailored learning opportunities for ongoing skills development.

• Multi-directional career paths that offer professional growth and development through new challenges, internal mobility and expanded roles.

• We actively nurture an environment that builds a sense of inclusion belonging and connection, including eight Employee Resource Groups. All Abilities, Asian Support Network, Black Leadership Network, Climate Action Network, Hola! MSCI, Pride & Allies, Women in Tech, and Women’s Leadership Forum.

At MSCI we are passionate about what we do, and we are inspired by our vision – to power better decisions. You’ll be part of an industry-leading network of creative, curious, and entrepreneurial pioneers.
