Job Description:

Wrike’s Backend Reliability (BRE) team is the backbone of our backend infrastructure and the guardian of our uptime. Our mission is to achieve and sustain 99.99% availability while building the tools, components, and safety nets that the entire engineering organization relies on. As a Senior / Staff Backend Engineer on this team, you won’t just close tickets - you’ll architect core reliability solutions that shape how Wrike scales, performs, and recovers from failure.

Job Responsibility:

  • Design, build, and maintain critical reliability components such as HTTP rate limiters, internal DB schema migration tools, circuit breakers, and distributed Redis-based caching
  • Troubleshoot complex production issues, optimize PostgreSQL usage, and ensure our distributed systems remain performant and stable under high load
  • Lead preliminary investigations during severe production incidents: identify likely root causes, assess impact, and propose mitigation options
  • Create scalable, reusable tools and frameworks that help other engineering teams build more resilient services
  • Leverage AI-powered tools and coding agents to accelerate development, analyze architectures, and automate repetitive or error-prone tasks
  • Influence reliability best practices across engineering by sharing knowledge, reviewing designs, and setting high technical standards

Requirements:

  • Strong expertise with Java/JVM, building scalable, high-performance backend systems
  • open to leveraging other languages when appropriate
  • Solid understanding of distributed systems concepts, including high availability, CAP theorem, and fault tolerance
  • Deep experience with relational databases (PostgreSQL) and key–value / non-relational storages (Redis)
  • Practical experience with containerization and cloud-native environments, including Docker and Kubernetes
  • Hands-on experience with message brokers such as RabbitMQ or Kafka
  • Ability to work independently with minimal supervision, using critical thinking to question assumptions and validate your own decisions
  • Strong written and spoken English skills suitable for collaborating in an international engineering environment

Nice to have:

  • Background in infrastructure engineering or Site Reliability Engineering (SRE), including infrastructure-as-code practices
  • Experience leading technical initiatives, driving cross-team projects, and mentoring other engineers while remaining an individual contributor
  • Familiarity with observability and monitoring stacks (e.g., Graylog, Zabbix, Grafana) and/or data analytics tools such as BigQuery
  • A strong interest in how complex systems fail and a track record of designing them to recover gracefully
What we offer:
  • 25 calendar days of paid vacation
  • Sick Leave Compensation (5 Paid Uncertified Sick Days)
  • Parental Leave: 18 Weeks Maternity / 4 Week Paternity
  • 2 Volunteer Days
  • Medical Insurance (Employees + Dependents)
  • Hybrid Working Model
  • School Allowance (Up to €600/month for school aged kids)
  • Simcard w/ Unlimited Internet Access for active employees
  • Office Lunch Allowance (via Wolt) on Wednesdays / Thursdays
