Grape Up is a consulting and technology company helping enterprises build mission-critical applications by leveraging AI, cloud-native technologies, and modern software delivery practices.

We’re looking for an experienced engineer to join a senior, dedicated team providing production support and evolution for a major automotive OEM’s connected-vehicle platform – a portfolio of web applications and microservices covering telematics, subscriptions, payments, and remote services. You’ll resolve real production issues, then use what you learn to make the platform measurably better: refactoring, breaking down legacy monolithic pieces, modernizing the stack, and raising the bar on observability and automation.

What to expect from this role
We work in a shifted schedule (10:00–18:00), which allows the team to better align with global client time zones and ensure solid coverage for production operations. We’re looking for someone who’s comfortable with, or prefers this setup.

• Own the full incident lifecycle for live production services – triage, resolve, and run root-cause analysis on high-severity (P1/P2) incidents so they don’t come back

• Write permanent fixes, hotfixes and patches in a modern Java 21 / Spring codebase, not just workarounds

• Identify and drive technical improvements, harden reliability and performance

• Level up observability and automation: add the missing logs, metrics and traces, build self-healing and alert-noise reduction, and automate the toil out of operations

• Handle system lifecycle work – framework/library upgrades, security patching, vulnerability remediation, End-of-Life monitoring

• 3+ years of experience building and/or supporting backend applications on the JVM, with strong Java and Spring

• Experience operating microservices and web applications in production, including troubleshooting live issues

• Working knowledge of AWS and CI/CD pipelines

• Hands-on experience with observability tooling (logs, metrics, traces) and production monitoring

• Solid Git skills and understanding of security-and-compliance practices

• Excellent command of English and Polish (all communication, reports and documentation are in English)

• Analytical thinking and strong problem-solving skills

• Comfort with a shifted work schedule (10:00–18:00) and openness to occasional international business travel

• Experience supporting automotive OEM or connected-vehicle platforms

• Familiarity with application servers such as Tomcat

• Experience in production-support / on-call / SRE-style roles and incident management

• Familiarity with ServiceNow, JIRA and Confluence in an operational context

• Comfortable working across the stack – primarily Java/Spring backend, with some React Native mobile support

• Experience with certificate/secrets management and disaster-recovery testing
