Responsibilities
- Carry the on-call rotation for Zello's most critical infrastructure. Lead incident response, write runbooks, and turn each incident into a durable improvement.
- Build observability where it's missing. Set SLOs, instrument services with Grafana and Loki, and shift team posture from reactive to proactive.
- You've carried real production weight on distributed systems at scale, and you talk about reliability as something you own, not something you measure.
- A management or tech-lead-without-keyboard role.
Requirements

Nice to have
- Contribute to backend 2.0: a ground-up modernization of the platform anchored on AI-native engineering workflows (AGENTS.md http://AGENTS.md, CLAUDE.md http://CLAUDE.md,.cursor/rules).
- You've shipped C++ in production for years and read long-lived backend codebases without flinching.
- Rust or Go in your toolkit is a plus.
- You've gone deep on at least one of Cassandra, MongoDB, or MySQL, and can name the tradeoffs because you've felt them in production.
- You use AI-assisted development as a default and have shaped CLAUDE.md http://CLAUDE.md, AGENTS.md http://AGENTS.md,.cursor/rules, or equivalent for a real team.
- You thrive on a small team where every hire moves the needle.
- You drop ego in code review.
- You take scope, you don't wait for it.
Benefits
- Have extended observability coverage with Grafana and Loki dashboards and alerting, shifting the team's posture from reactive to proactive on at least one reliability dimension.
