Principal Software Engineer- Substrate SPARTANs

Navigate ambiguity. Take on problems where the requirements, ownership, and sometimes the root cause are all unsettled. You build a working model of an unfamiliar codebase quickly, form a defensible hypothesis, and convert open-ended asks into scoped projects with clear success criteria. Drive results end to end. Own the technical outcome of high-visibility projects from problem framing through deployment and measured impact. You set the bar for clean, testable, observable code, and you leave reusable patterns, documentation, and playbooks behind, so the gain does not decay after we move on. Operate across boundaries. Build the coalitions the work depends on. You align partner teams who do not report to you, negotiate dependencies and sequencing, and land changes across repositories and service boundaries you do not own. You represent the technical position credibly to executives and to the engineers who will live with the design. Exercise strong judgement. Decide what to build, what to defer, and what to stop. You weigh reliability, cost, compliance, and time-to-impact under incomplete information, make the call, state the tradeoff explicitly, and revisit it when the evidence changes. Raise the reliability and performance bar. Diagnose and fix latency, scale, and cost problems in always-on distributed services; improve resilience, observability, and incident readiness; and serve as a Designated Responsible Individual across products where the engagement calls for it. Grow the engineering community. Mentor senior and principal engineers, review designs across the organization, and develop in others the techniques you use to ramp fast and reason well. You model a growth mindset that treats mistakes as a source of more reliable engineering.
