Why This Job is Featured on The SaaS Jobs
Zinier sits in the SaaS segment focused on operational workflows for deskless and frontline teams, where product reliability and integration depth tend to determine adoption. A Senior Platform Support Engineer (L2) is therefore positioned at the point where real customer usage meets platform behavior, handling complex incidents that span workflow logic, APIs, data, and cloud infrastructure. In SaaS terms, this is a role close to production truth rather than feature roadmaps.
For a long-term SaaS career, the value comes from repeated exposure to the mechanics that keep subscription software dependable at scale: incident leadership, root cause analysis, and feedback loops into engineering. The mix of observability tooling, SQL performance work, and API troubleshooting builds a durable skill set that transfers across B2B platforms, especially those with configurable products and integration-heavy deployments. Mentoring and runbook ownership also develops the operational rigor many SaaS organizations rely on as they mature.
This role fits engineers who prefer investigation over greenfield build work and who take satisfaction in turning ambiguous production symptoms into clear diagnoses and preventative fixes. It will suit someone comfortable coordinating across support and engineering, and interested in shaping how technical support operates, not only resolving tickets.
The section above is editorial commentary from The SaaS Jobs, provided to help SaaS professionals understand the role in a broader industry context.

ROLE OVERVIEW
We are looking for a Senior Platform Support Engineer who brings advanced technical depth and independent ownership to the support function. 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.
WHY JOIN US
- Unique opportunity to form a front-facing layer that not only is the front-line to customer deployments, but also has the ability to work closely with Solution Architects and others to influence Product blueprints.
- Work across the full tech stack — from debugging backend services(Java, spring boot) to exploring front-end interfaces built with React and extending into mobile UI development.
- Build internal tools, fix production issues, and contribute to engineering stability, all while learning from experienced platform, product and solution engineers.
- Be part of a high-impact team that bridges engineering and customer experience, where your work helps improve both product quality and customer trust.
- Join a company that values learning, ownership, and long-term growth.
- This role is aligned to the SDE1 capability level. High performers progress to:
- Tech Lead, Platform Support
- Principal Platform Support Engineer
- Team Lead, Platform Support
