Principal Systems Developer – Kernel

The InterSystems IRIS data platform is the engine behind some of the world’s most important applications.

At its core is a super scalable, high performance database engine built to naturally and flexibly store data accessed from multiple data models, including multi-dimensional arrays, key/value, relational tables, and objects.

The database engine runs on a variety of operating systems including Linux, AIX and Windows.

It’s designed to scale on large NUMA machines, distributed cache clusters, and the cloud.

The database kernel team needs a creative and motivated developer to join them in designing, implementing and enhancing components of the database engine and its embedded programming language.

As part of a small team at the center of the data platform, you can expect to make a large impact with a high degree of independence.

• Compose elegant, efficient, reliable and maintainable source code in C, with some C++
• Analyze, develop and optimize algorithms and data structures for efficiency in memory and/or modern storage devices
• Analyze and understand concurrency control and memory ordering issues around access to shared memory structures
• Learn, maintain and extend the embedded database programming language (ObjectScript) that comprises the application interface to the database
• Enhance interactions with modern operating systems and hardware devices
• Develop and maintain database management APIs
• Debug complex problems; develop and run test code
• Compose internal design documentation and guide external documentation
• Stay up to date with operating system, storage and database technology

• 10+ years developing low-level system code for mission-critical software
• Experience in C or C++; assembly is a plus.
• Strong technical knowledge of computer architecture, operating systems, concurrency control, compiler and interpreter methods, and software engineering techniques
