Engineering's Ability: Ruby

You develop expertise in our server-side stack in the Ruby ecosystem and whatever comes next.

I have observed this person showing a consistent, comfortable, continuous, and clear positive impact to a squad when wielding this ability, and therefore I would put them in situations where they can employ this ability with only a small amount of guidance

• You understand Ruby syntax
• You write code according to our Ruby Style Guide.
• You write basic unit tests with RSpec.
• You fix isolated bugs by making improvements to our Ruby code.

I have observed this person showing a consistent, comfortable, continuous, and clear positive impact to a squad when wielding this ability, and therefore I would put them in situations where they can employ this ability, with no assistance as well as being a trusted active or passive mentor to others

• You make use of and, when called for, creates new abstractions to eliminate inconsistencies and duplication.
• You assess the correctness and utility of existing code and avoid uncritical copy-pasting.
• You ask questions to identify (and make explicit) the unspoken requirements of application functionality (such as tracking, logging, and edge cases).
• You ensure data is kept private and secure when writing code.
• You create jobs to perform an asynchronous service

I have observed this person showing a consistent, comfortable, continuous, and clear positive impact to multiple squads when wielding this ability, and therefore I would put them in situations where they can employ this ability as well as being considered an expert within this discipline

• You identify needs for new patterns (such as policy objects) and successfully usher their adoption, adding clarity and consistency around common approaches.
• You act as a caretaker for our Ruby codebase, e.g. by contributing to our linter configuration and Style Guide.
• You identify and spearhead high-leverage optimizations (such as switching from JSON to Oj for faster JSON serialization)
• You identify, guide, and help ensure the team is utilizing the most performant Ruby methods.

I have observed this person showing a consistent, comfortable, continuous, and clear positive impact to a squad when wielding this ability, and therefore I would put them in situations where they can not only employ this ability but where they set the tone for this at the company level

• You usher the adoption of new technologies that change in fundamental ways how our product works for both users and engineers.
• You pioneer architectural changes that empower all server-side engineers to be more productive.

I have observed this person showing a consistent, comfortable, continuous, and clear positive impact to not just internal teams but the community/industry in general when wielding this ability, and they are recognized by the community/industry as an expert

• You implement new Ruby techniques and frameworks to meet the needs of the wider community.
• You define and promote a long-term vision for our server-side architecture and coordinates across the team to ensure projects are in service of it.
