Profile match
Acaisoft is a Polish software house providing custom software development and cloud-native managed services for international clients. Operating since 2015, it supplies backend, platform, data and Kubernetes engineers to projects such as observability platform migrations and also has a US contact office in San Jose. The company is headquartered in Warsaw, Poland.

Hi there! If you’re looking for a high-impact position in an ambitious software house we’ve got a match for you!


Right now, we are looking for a Java Engineer to join a project focused on developing a database proxy application. The solution acts as an additional layer between clients' applications and databases.

The proxy operates at a low level, emulating a real database without requiring any changes on either the client or database side. Once integrated into an environment, the product offers a range of benefits, including advanced monitoring tools and an additional security layer for database administrators, as well as query caching to improve performance for application developers.

Our team focuses primarily on developing new features, but since the product is already used by customers, we also take care of bug fixes and ongoing improvements. This role offers an opportunity to develop your skills by tackling a wide variety of challenges across different technological layers.


Zakres obowiązków

  • Developing new features related to new database vendors or new use cases.
  • Continuous improvement of the quality of the product along with fixing customer-facing issues.
  • Preparation of a report summarizing the work done on a given day.
  • Writing reusable, testable, and efficient code following the best software development practices.
  • Helping our customers to achieve their solutions' scalability.
  • Participating in the requirement discussion meetings, and providing feedback on inconsistencies.

Wymagania

Must have:

  • At least 6 months of commercial experience in software development - MUST HAVE!
  • Structured knowledge in the field of databases (MySQL, PostgreSQL, MSSQL)
  • Solution-oriented way of working.
