Podsumowanie oferty

As part of Kraken’s Core Infrastructure Engineering team, you’ll assess and improve the shared data systems behind critical production services. You’ll set direction for the database estate and deliver hands-on improvements, with MariaDB at its centre and Kafka, Redis and Elasticsearch across the platform.

Wymagania

8+ years operating and evolving production database estates at scale, assessing inherited systems, setting technical direction and delivering improvements with engineering teams.
Strong understanding of high availability, replication and distributed database failure modes, including consistency and availability trade-offs, transaction boundaries and transactional outbox patterns.
Deep, recent hands-on MariaDB expertise, including InnoDB, MVCC, transaction isolation, locking, query optimisation, binary logs and MariaDB GTID replication.
Personal ownership of MariaDB incident diagnosis, performance tuning and tested restore or point-in-time recovery.
Strong software engineering skills in Python, Go, Rust or a comparable language, and experience building and maintaining production software or automation for database workflows using version control, code review and delivery pipelines.
Strong low-level Linux, Kernel, storage and networking fundamentals.
Clear written technical judgment and demonstrated delivery across teams without reporting-line authority; ability to support database design and lifecycle decisions and develop experienced engineers.

Nice to have:

Experience operating databases in containerised, hybrid on-premises/cloud or multi-region environments; familiarity with Kubernetes, infrastructure as code or GitOps.
Experience with database proxies or load-balancing layers such as MaxScale, HAProxy or ProxySQL.
Experience with PostgreSQL, Vitess, TiDB, ScyllaDB, ClickHouse or internal database platforms; operational knowledge of Kafka, Redis/Valkey or Elasticsearch/OpenSearch.
Experience in regulated environments or contributions to database engines, operators and other infrastructure software.

Obowiązki

Review the database estate against business needs and production evidence, assessing reliability, scale, cost and operational complexity.
Define target architecture and measurable goals; agree a prioritised roadmap with engineering leads and dependent teams.
Execute the roadmap through design, implementation and adoption, including migrations and scaling decisions; verify results in production.
Investigate MariaDB failures and performance limits; improve reliability through observability, safer changes, and tested backup, restore and disaster recovery procedures.
Build and maintain production software for database provisioning, upgrades and routine maintenance; make self-service workflows safe and auditable with access controls and change evidence.
Work with application teams on schemas, transaction boundaries, queries and data-store choices, and resolve cross-team dependencies.
Mentor engineers through design reviews, pairing and incident analysis.
Participate in on-call and incident response, and follow through on production lessons.
