Who is Cray?

Our business is supercomputing. Our primary aim is understanding the problems our customers are trying to solve and developing the technologies that enable them to make the discoveries that better our world. Cray combines computation and creativity so visionaries can keep asking questions that challenge the limits of possibility. Drawing on more than 45 years of experience, Cray develops the world’s most advanced supercomputers, pushing the boundaries of performance, efficiency and scalability. Cray continues to innovate today at the convergence of data and discovery, offering a comprehensive portfolio of supercomputers, high-performance storage, data analytics and artificial intelligence solutions. 

We are proud to be an Equal Opportunity Employer including women, minorities, protected veterans, and individuals with disabilities.  CRAY Inc. is an Affirmative Action, Equal Opportunity Employer.  

Who We Need

For those who ask what if, Cray is a partner that merges computation and creativity to extend the boundaries of what you can discover.  Our greatest achievements are realized when we face what seems impossible, and that’s why we invite those who believe anything is possible to join us and to keep asking what if, why not, and what’s next.

At Cray we’re always looking way down the road … years, even decades into the future. We’re not developing products for next quarter. We’re developing products for questions our customers might not even know they have yet. That’s how high-performance computing works. So as you can imagine, we pay very close attention to what’s coming … and that includes the next generation of computer scientists and engineers. These individuals are going to be the ones shouldering an awesome responsibility in the coming decades as big data gets bigger, artificial intelligence flexes its muscles more and more, and problems grow in complexity.  

Cray has an opening for a motivated and skilled software developer to join its Chapel development team. The Chapel Development Engineer will work on improving the Chapel language . Ideal candidates will have experience with compiler optimization and LLVM-based code generation. Ideal candidates will also be acquainted with processor ISAs, GPU programming, and language semantics. This position would include the ability to conduct in-depth compiler debugging and product development activities. This work includes the design and implementation of new compiler-based optimizations, enhancing the interface between the Chapel and the LLVM-based code generator and working to improve the overall quality of the Chapel compiler.

	• B.S. Computer Science or similar discipline is required.  Advanced degrees are welcome. At least 3 years of experience in compiler development or equivalent combination of education and experience, particularly with regards to compiler optimization. 
	• Background in high performance computing architectures, including multiprocessing and vectorization, is highly desired. 
	• Experience with the LLVM ecosystem is highly desired.
