The Staff Platform Engineer leads the effort to locate, make visible, and remediate sources of unreliability in the MANTL platform, including correctness problems that surface under failure conditions. This role works directly in the platform's application codebase (TypeScript) and its container-native deployment environment, combining application-engineering skill with reliability-engineering practice at a level of scope and independence beyond the Sr Platform Engineer. In addition to resolving reactive issues as they surface, this role owns and prioritizes a standing roadmap of known reliability risks, driving that work forward on its own timeline. This role partners with, but is organizationally and functionally distinct from, both Cloud Infrastructure Engineering and product application engineering teams, and is expected to set technical direction and standards for platform reliability work.

Essential Duties & Responsibilities

• Lead investigation, troubleshooting, and resolution of the most complex reliability issues within MANTL platform application code, including microservice communication failures and correctness issues that emerge under failure conditions

• Set direction for how the platform identifies and addresses failure modes across its third-party and internal system integrations, establishing resilience strategies suited to each integration's specific behavior

• Own the design and evolution of monitoring, dashboards, and alerting strategy (Datadog preferred) across the platform, ensuring proactive visibility into emerging risks

• Establish standards and lead implementation of distributed tracing across microservices to accelerate root-cause identification organization-wide

• Lead diagnosis and remediation of significant application performance issues, including caching strategy, inefficient code paths, and query performance

• Set direction for platform and application hardening practices, including fault-injection and resilience testing, and drive adoption of defensive design patterns to prevent recurrence

• Own and improve CI/CD build pipeline architecture (GitHub Actions) supporting deployment of the platform

• Guide deployment and troubleshooting of container-native (Kubernetes) workloads as part of resolving complex platform reliability issues

• Define, prioritize, and drive execution of a roadmap of known reliability risks, independent of feature-delivery timelines

• Establish and maintain documentation and runbook standards covering platform reliability issues, root causes, and remediations

• Serve as the senior escalation point for complex platform reliability issues, partnering with Cloud Infrastructure Engineering and application engineering leadership on issues that cross domain boundaries

• Define reliability targets (SLOs/SLIs) for key platform services and advise leadership on reliability risk and tradeoffs

• Provide technical mentorship and guidance
