Full description

Our mission is to offer the best-in-class AI-powered technologies to empower small, medium, and large businesses in their staffing & recruitment transformation.
Lead Site Reliability Engineer (SRE)
Manatal is establishing a dedicated Site Reliability Engineering function for the first time. As the platform and customer base grow, the need for structured incident response, mature observability, and reliable on-call operations requires dedicated ownership.
The Lead Site Reliability Engineer will be the first dedicated hire in this function. Working closely with the CTO, the Director of Engineering and the Director of Product, this role owns incident response, on-call operations, and the observability stack. When production incidents occur, this person leads. Between incidents, they improve the systems, alerting, and processes that detect and prevent issues.
This is a senior individual contributor role with significant cross-functional authority. The successful candidate will ensure platform reliability and security posture. There are no direct reports initially, though the function may grow over time.
Responsibilities
Incident Response
- Lead all production incidents: triage, coordinate response across engineering teams, communicate status to stakeholders, and drive resolution.
- Own the incident management process end-to-end: detection, escalation, communication, resolution, and post-mortem.
- Write and maintain incident runbooks to enable faster response and reduce dependency on individual knowledge.
- Conduct blameless post-mortems after every significant incident. Track follow-up actions and ensure they are completed.
On-Call Operations
- Own and lead the on-call rotation: define schedules, escalation policies, and response expectations.
- Continuously improve on-call quality by reducing alert noise, eliminating false positives, and ensuring alerts are actionable.
- Analyze on-call patterns to identify recurring issues and drive permanent fixes with engineering teams.
Observability & Monitoring
- Own the observability stack: Datadog (infrastructure monitoring, APM, logging) and Sentry (error monitoring).
