Database Engineer

"Software engineer at heart with a passion for databases."

Open positions

Do you have a solution-oriented mindset? Are you ready to spend the majority of your time making application changes to improve database performance, scalability, and reliability, and delivering foundational database solutions and best practices for our backend engineering teams? Join Ataccama as a Database Engineer and enjoy a hybrid role: part software engineer, part database expert.
Not based in Prague? If you’re open to either remote cooperation or relocation, reach out to us anyway to find out what the options are. #LI-remote

Your challenge

  • Proactively identify database performance impediments and resolve them by proposing and delivering changes to the codebase. Own this process end-to-end, from triaging issues to verifying your solution in cloud production.
  • Deliver application changes that allow us to scale the application and its database further and make sure we're prepared for data growth on both cloud and on-prem installs.
  • Provide database expertise to engineering teams through code reviews, pairing and training to help deliver optimal database designs and queries.
  • Review, optimize, and refactor the existing database schema.
  • Create and incrementally improve documentation to reduce tribal knowledge, including:
  • Database best practices
  • Workflows and database team processes
  • Target architecture and long-term scalability considerations
  • Improve tooling to detect performance bottlenecks early in the development cycle. 

What you´ll work on?

  • Identify problematic database patterns by analyzing Ataccama Gen2 project workload and implementing/suggesting solutions.
  • Implement a partitioning strategy framework for large tables.
  • Implement building blocks to efficiently load, analyze, and migrate data.
  • Analyze tables and optimize them by adding indexes, breaking them up into separate tables, or by removing unnecessary columns.
  • Improve index usage (remove unused, identify missing).
  • Improve our application-side database load balancing implementation.
  • Review database-related changes submitted by other developers.
  • Document database best practices or patterns to avoid.

Is this you?

  • You understand on an expert level relational databases, SQL, and query optimization techniques. You are able to both diagnose and prevent performance problems. 
  • You have an expert-level understanding of the internals of PostgreSQL. 
  • You are capable of clearly and concisely communicating complex technical, architectural, and/or organizational problems and propose thorough iterative solutions. 
  • You have a positive and solution-oriented mindset. 
  • You have experience owning a project from concept to production, including proposal, discussion, and execution. 
  • You´re self-motivated and self-managing, with strong organizational skills. 
  • You have demonstrated the ability to work closely with other parts of the organization.

What else we’d appreciate?
