You will handle the most complex L2 cases on the platform, mentor junior engineers, and act as a bridge between support and engineering/product teams. This role suits engineers who thrive in ambiguous, high-impact situations and want to shape how support excellence is delivered at Zinier. KEY

RESPONSIBILITIES Own and resolve advanced L2 incidents end-to-end, including root-cause analysis, customer communication, and post-incident documentation. Investigate escalated issues involving JavaScript workflow logic, JSON configuration errors, API anomalies, and database irregularities. Analyse Grafana dashboards and observability stacks (Loki, Tempo) to detect and diagnose system anomalies proactively. Review and optimize SQL queries to identify performance bottlenecks and data integrity issues during live incidents. Mentor and guide Platform Support Engineers on debugging approaches, RCA writing, and escalation best practices. Lead knowledge-base initiatives — authoring runbooks, troubleshooting guides, and technical SOPs. Partner with engineering and solutions teams in postmortems, providing structured feedback to improve product robustness. Contribute to tooling and internal automation that reduces manual effort across the support function. Participate in on-call rotations and lead critical-incident response when senior escalation is needed outside business hours. REQUIRED SKILLS & EXPERIENCE 4+ years of experience in technical support, customer engineering, or solution development. Strong hands-on skills in JavaScript (workflow debugging, process rule analysis) and JSON handling. Proficiency in SQL — able to write, debug, and optimise queries and diagnose data anomalies. Familiarity with observability tools such as Grafana, Loki, or Prometheus. Solid understanding of REST API interactions, HTTP semantics, and integration patterns. Experience with AWS or equivalent cloud platform at a working level. Demonstrated ability to mentor junior engineers and drive knowledge-sharing within a team. Excellent communication skills — able to distill complex technical findings into clear customer and internal communications. DESIRABLE SKILLS Exposure to backend development in Java/Spring Boot or frontend in React. Understanding of field service management or workflow-orchestration domains. ITIL V3/V4 foundation or equivalent service-management certification. Experience building or contributing to internal tooling or automation scripts.
