Sr. Software Engineer (Database)

A Senior Software Engineer in the database platform team has knowledge and ideas on how to develop innovative solutions smartly. The database platform is being built by a team that has the culture and the environment technologists find at a startup. We are looking for outstanding software engineers with strong development experience in building scalable and geo-distributed solutions. The ideal candidate will have a strong understanding of relevant programming languages, databases, transaction systems, distributed systems, consensus algorithms, replication, design patterns, storage, and networks. Exceptional problem-solving abilities will be critical for success, as will be a focus on quality. In our environment, quality is everyone's responsibility, passion is key, and innovation and creativity are strongly encouraged. The successful candidate will participate in the entire lifecycle of a product ranging from architecture through testing and

production rollout.

Responsibilities:

• Be part of a team of phenomenal engineers building a next-gen database platform using the latest open-source technologies.
• Design and implement differentiated production-ready features in a fast-paced environment with a focus on scalability, performance, geo-distribution, and availability.
• Roll out features at the pace of business changes and requirements.
• Passion to bring out innovative ideas and try out new solutions, while being open-minded to feedback from the team.
