Responsibilities

• Contribute to highly-scalable services (stateless and stateful) running in multiple regions, supporting spiky but predictable workloads, deployed via multi-stage rollouts.
• Improve existing services, analyze runtime and cost efficiencies, and suggest improvements.
• Lead development of new services such as a Kubernetes operator or cloud storage caching layer.
• Participate in technology evaluations and architecture evolution discussions.
• Harden and productize internally or externally developed libraries and services.
• Re-evaluate the relationship between backend services and user-facing applications to drive scalability improvements.

Requirements

• Proficiency with Rails (or similar full-stack framework), including strong understanding of ActiveRecord (or analogous ORM), database schema design, and query performance/optimization.
• Proficiency with Kubernetes and Go (or another systems language), including strong understanding of garbage collection and profiling. Cgo experience is a bonus.
• Familiarity with GCP/GKE, Linux, Docker, Ruby/Rails, Redis, ffmpeg (or equivalents).
• Experience in a SaaS or PaaS environment at scale (100s of millions of async jobs per week). Video streaming at scale is a bonus.
• Curiosity-driven and pragmatic with focus on results.
• Generalist mindset with ability to dive deep into varied challenges.
• Resilience, attention to detail, and ability to work through complex problems.
• Openness to disagreement and commitment to decisions.
• Strong collaboration and communication skills for both technical and non-technical audiences.
• Independence in managing workload and priorities.
