Most work happens in Golang, running on Kubernetes across AWS and GCP, shipped through CI/CD with clear SLOs, strong observability, and safe rollouts. You’ll lead projects that reduce latency and incidents, improve unit costs, and simplify our platform, while partnering with other teams. You’ll join our on-call rotation with solid runbooks, mentor engineers, and set a high bar for design, code, and operations.

- Database Skills: Proficiency in database modeling, optimization, and query performance, preferably with relational databases.
- Problem-Solving: Ability to independently drive decisions and solve complex technical challenges.
- Team Player: Strong interpersonal skills, with the ability to build trust and rapport with internal and external stakeholders.
- DevOps Tools: Familiarity with CI/CD tools and workflows, and a willingness to explore new technologies and become a Subject-Matter Expert.
Even better if you have
- Multi-region or large event scaling experience.
- Observability depth: Prometheus/Grafana, OpenTelemetry tracing.
- Traffic shaping: canary, blue-green, feature flags.
- Data pipelines or queueing at scale; backpressure patterns.
- Migrations or provider swaps with zero/minimal downtime.
