Job Description
MathWorks has a hybrid work model that enables staff members to split their time between office and home. The hybrid model provides the advantage of having both in-person time with colleagues and flexible at-home life optimizations. Learn More: https://www.mathworks.com/company/jobs/resources/applying-and-interviewing.html#onboarding.
We are seeking a Principal Software Engineer to work on the core programming language and runtime systems that form the foundation of MATLAB. In this role, you will help design, implement, and evolve the language semantics, execution capabilities, and runtime infrastructure used by millions of engineers and scientists worldwide.
This is a handson, technical role focused on building and modernizing foundational systems-improving language consistency, advancing performance and correctness, and refactoring longlived subsystems to support new capabilities, composable execution, and AIassisted development workflows.
MathWorks nurtures growth, appreciates inclusivity, encourages initiative, values teamwork, shares success, and rewards excellence.
Responsibilities
- Design and implement enhancements to programming language features, execution semantics, and core runtime behavior, with attention to performance and correctness.
- Lead and contribute to largescale refactoring efforts, improving modularity, clarity, and testability of mature systems while preserving external behavior and compatibility.
- Evolve internal APIs and abstractions that enable other teams to build language features, tooling, and integrations safely and efficiently.
- Diagnose and resolve complex crosscutting issues related to execution behavior and interactions between subsystems.
- Participate in design reviews and architecture discussions, helping shape the longterm technical direction of the language and runtime.
- Mentor other engineers through code reviews, technical discussions, and shared ownership of foundational systems.
Qualifications
- Strong understanding of software design principles and maintainable architecture in large systems.
- Experience with AI-driven development workflow and automation.
- Ability to independently drive complex technical work from problem definition through implementation and delivery.
- Experience working effectively in large, longlived codebases with many users and dependencies, including largescale refactoring efforts.
- Experience developing performancecritical systems.
- Familiarity with developerfacing tools such as debuggers, static analysis, or language tooling.
Required Qualifications
- Expertise with C++
- A bachelor's degree and 10 years of professional work experience (or equivalent experience) is required.

About MathWorks
MathWorks is the leading developer of mathematical computing software. MATLAB, the language of engineers and scientists, is a programming environment for algorithm development, data analysis, visualization, and numeric computation. Simulink is a block diagram environment for simulation and Model-Based Design of multidomain and embedded engineering systems. Engineers and scientists worldwide rely on these product families to accelerate the pace of discovery, innovation, and development in automotive, aerospace, electronics, financial services, biotech-pharmaceutical, and other industries. MATLAB and Simulink are also fundamental teaching and research tools in the world's universities and learning institutions. Founded in 1984, MathWorks employs more than 5,000 people in 16 countries, with headquarters in Natick, Massachusetts, USA.
Mission: Our goal is to change the world by accelerating the pace of discovery, innovation, development, and learning in engineering and science.
We work to provide the ultimate computing environment for technical computation, visualization, design, simulation, and implementation. We use this environment to provide innovative solutions in a wide range of application areas.
