Job description

Our client's team is solving one of the most difficult open problems in the software database industry today: scaling SQL. They have their own distributed relational database, built from the ground up with a shared nothing architecture, distributed query execution, and automatic data distribution.
As their customer base grows, both in number and in size of deployment, so too has the performance demands on the product and staff. The clusters are getting bigger, databases are growing larger, and workloads are growing more complex. We are looking for a Senior Performance Engineer to join the team who can lead performance investigations which push the limits of our technology.
Responsibilities
As a member of Performance Engineering Team:
  • You will own defining test strategies and designing and implementing measurement and analysis tools needed in our performance studies.
  • You will work collaboratively with other engineering teams to help profile performance and scalability, identify areas for improvement, and influencing changes to the database.
  • You will work on a variety of workloads ranging from traditional OLTP and decision support performance benchmarks, to more complex, evolving hybrid transaction and analytical processing workloads.
  • You will work closely with sales engineering and support teams to do deep-dive and root cause analysis of key customer performance issues.
  • You will work in conjunction with marketing and sales to investigate the competitive performance of our product resulting in potential technical blog posts for either internal or external publication.

Qualifications
Do you have passion for performance engineering? Do you like to push the limits of the performance of a database product? Do you have the mindset of a scientist? Do you like to discover knowledge through controlled experimentation?
  • Knowledge of Linux operating system with familiarity with bash shell programing skills.
  • Knowledge of database systems and familiarity with the SQL query language.
  • Programming skills using C, Python and/or Java.
  • Knowledge of database performance benchmarks, measurement and analysis.
  • Familiarity with applications and their interaction with databases is a major plus

What's in it for you?
Impact the world of technology by pushing the boundaries of technology and business models. Be part of a game-changing organization that encourages outside-the-box thinking, empowerment, and is truly shaping the future of the software industry. You'll be collaborating with high-caliber colleagues around the world, offering unparalleled learning and growth opportunities. We provide a very competitive compensation package, 25 days paid annual leave (plus holidays), stock options, a massive degree of flexibility and freedom, and more.
Here are some of the reasons why you'll enjoy being a part of the team:
  • Our team is small, so you will own significant projects and contribute in a big way to the product.
  • We have a lot of interesting problems to work on, in a variety of areas.
  • Our customers love us. We help them do things they could never do with their legacy SQL databases.
  • We are passionate about making our software work better and faster
