Plan for the future
Propose, evaluate, select, and adopt new technologies when needed
Ensure that you are on top of changes to critical parts of our infrastructure (e.g. AWS, GRPC, Postgres, Redis, Envoy, RabbitMQ, etc.) so that we can adopt newer versions without affecting performance or functionality
Shape our API and third party integration strategy
Proactively suggest changes to balance cost, scale, security, performance, deployability and utility
Load test regularly, and plan for the next 1-2 orders of scale

Experienced (have 5+ years experience of designing and building commercial back end systems), with a strong analytical mind, and an ethical approach
Comfortable with the fundamentals of computer science and information architecture, including knowledge of data structures, algorithms, their complexity, their tradeoffs, and their implementation (e.g. trees, graphs, sorting algorithms, and their various Big O implications)
Someone who has led or been part of small teams of developers through the entire software development lifecycle, in maintaining and continually improving a lean software development process, and in delivering high quality code reviews, with a toolbelt of best practices for professional software development
