You embrace the "MVP" approach, designing & building incrementally and learning quickly from failures. You love tinkering and discovering innovative solutions. You're comfortable setting technical direction, eliciting ideas from both your team and our customers, and confident managing and supporting production systems, balancing reliability, performance, and operational excellence in live environments.
