MIT- Software Engineer Intern | Engine

**About SingleStore** --------------------- SingleStore is a cloud-native distributed SQL database built for real-time applications, analytics, and AI. Our platform unifies transactions and analytics so organizations can work with data quickly, reliably, and at scale. **About the Engine Team** ------------------------- The Database Engine team builds the core technology behind SingleStore, including query processing, optimization, storage, data ingestion, distributed systems, reliability, and performance. As an intern, you will join a small, collaborative engineering team and contribute to meaningful projects that move from design to production through our regular release cycles. You will learn from experienced engineers while developing a strong foundation in systems and database engineering. **About the Role** ------------------ As a Software Engineer Intern, you will design, implement, test, and improve production-quality software for the SingleStore database. You will work on well-scoped projects, participate in technical discussions and code reviews, and gain hands-on experience solving challenging problems in large-scale software systems. Your work may include: * Developing new features and improvements across the SingleStore database * Working on SQL query processing and query optimization * Improving storage engines, indexing, and data management * Building reliable distributed-system components * Working with concurrency, multithreading, and fault tolerance * Investigating performance, scalability, and correctness issues * Writing production code, tests, documentation, and technical designs * Collaborating with engineers, product managers, and cross-functional partners Depending on the team and project, you may also work with performance engineering, SIMD, LLVM-based code generation, search, vector search, cloud infrastructure, or AI data workloads. **Required Qualifications** --------------------------- * Currently pursuing a bachelor's or master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field * Strong foundation in data structures, algorithms, operating systems, and computer architecture * Understanding of concurrency, multithreading, and server-based systems * Programming experience in C++ or C * Strong analytical and problem-solving skills * Ability to communicate clearly and collaborate effectively with teammates * Curiosity, ownership, and willingness to learn Prior professional experience is not required. We welcome candidates who have developed their skills through coursework, research, projects, internships, or open-source contributions. **Preferred Qualifications** ---------------------------- * Coursework or project experience in databases, distributed systems, operating systems, compilers, networking, or storage systems * Experience debugging or optimizing systems-level software * Familiarity with Linux or Unix-based systems * Experience with performance profiling, memory management, or low-level programming * Experience contributing to production software or substantial technical projects **What You'll Gain** -------------------- * Hands-on experience building software for a production distributed database * Mentorship from experienced database and systems engineers * Exposure to database internals, query processing, storage, reliability, and performance engineering * Opportunities to collaborate across engineering and product teams * A supportive environment focused on technical growth and meaningful ownership * A deeper understanding of how software is designed, tested, released, and operated
