• Own target architecture, patterns, and guardrails for CreatorFi platform services (auth, data, orchestration, observability). • Write and/or review design docs; spike tricky pieces; set code-quality bars; merge complex PRs. • Proactively manage tech debt and trade-offs; keep the roadmap honest about platform risks and runway. • Run the engineering side of delivery: daily flow, unblocking, dependency management, and predictable on-time releases. • Coordinate with shared QA/DevOps; ensure CI/CD pipelines and environments are healthy and fast. • Define and own SLIs/SLOs and error budgets; instrument dashboards and alerts. • Enforce CI/CD gates, automated testing thresholds, code-review standards, and security scanning. • Lead operational readiness and incident response; drive fixes to completion. • Ensure structured logging, change control, access reviews, evidence collection, and control ownership. • Own the on-call rota for the squad; maintain runbooks and escalation paths. • Mentor engineers; raise the bar on PRs and design docs; pair where it matters. • Provide performance signals to engineering leadership; help with interviewing, leveling, and onboarding. • Co-author a plan/roadmap with clear milestones, exit criteria, and risk mitigation.
