You will design and evolve storage, query, and data-processing capabilities across relational databases and Elasticsearch/OpenSearch. Your work will directly influence how process data is stored, retained, queried, monitored, and exposed to customers. You will own substantial engineering initiatives from solution design through delivery, working closely with Product, QA, Support, and SRE. The environment is highly distributed and remote-first, with a strong emphasis on technical ownership, collaboration, and production excellence. You will also contribute to challenging problems around performance, scalability, data pipelines, and reliable operation at scale. The role offers the opportunity to shape a critical data layer while contributing to an increasingly AI-driven enterprise software platform. Accountabilities: * Design, build, maintain, and improve backend services responsible for storing and serving process data at enterprise scale. * Develop solutions across relational databases and Elasticsearch/OpenSearch, balancing correctness, performance, availability, scalability, and maintainability. * Own engineering initiatives from requirements discovery and solution design through implementation, coordination, delivery, and production rollout. * Partner closely with Product Management and cross-functional engineering teams to translate business and customer requirements into actionable technical solutions. * Evolve data processing, retention, storage, and exposure capabilities to meet changing customer and product requirements. * Improve the performance and scalability of secondary storage systems as usage and data volumes grow. * Build internal tooling and operational capabilities that make the data layer easier to understand, troubleshoot, monitor, and operate safely in production. * Investigate production data issues, including slow queries, execution plans, indexing problems, and other performance bottlenecks, and drive them through root-cause analysis and resolution. * Participate in L3 support and on-call rotations, collaborating with Support and Site Reliability Engineering teams to resolve production incidents. * Use production learnings and operational insights to continuously improve the reliability, performance, and usability of the data layer. * Provide and receive clear, constructive feedback through code reviews and technical collaboration. * Contribute to the evolution of engineering practices and architecture within a remote-first, cross-functional environment. ## Related Videos - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Optimizing Discovery: PostgreSQL's Role in Transforming GetYourGuide's Search](https://www.wearedevelopers.com/videos/1647-optimizing-discovery-postgresql-s-role-in-transforming-getyourguide-s-search) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Branch your database like your code: How schema changes and pull requests go hand in hand](https://www.wearedevelopers.com/videos/350-branch-your-database-like-your-code-how-schema-changes-and-pull-requests-go-hand-in-hand) - [Dynamic Entities in .NET: Building Low-Code Systems on Top of Entity Framework Core](https://www.wearedevelopers.com/videos/100218-dynamic-entities-in-net-building-low-code-systems-on-top-of-entity-framework-core) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk)
