Job expectations Does the right thing with little or no direction. Has good judgement, is proactive, and writes high‑quality code.

Able to methodically break down complex problems and write solutions that are correct and use appropriate levels of class and method abstractions that make the code easy to understand and as simple as possible. Able to understand complex code and enhance and modify it correctly. Understands and can implement a full flow involving asynchronous code correctly. Is comfortable and successful with the complexity of the design and implementation of an entire stack (deployable unit) comprised of several classes. Has independently developed many well designed and implemented stacks. Independently (without help from other engineers or customers) verifies that functionality meets customer requirements. Writes effective automated unit, regression, and integration tests that verify correct implementation. Significantly faster than mid‑level engineers with improved quality.

Using good judgement, thinks through challenges and determines several possible solutions, tries different things, reaches out for help, doesn’t wait for manager to solve problems, but also gets verification of approach before carrying it out. Verifies requirements, identifies missing or conflicting requirements, and actively works to clarify those requirements. Raises concerns of possible defects and ways code could be improved as they notice things in working in the code of various stacks. Has an ownership mentality and wants to make things the best they can be. Produces production‑level code independently.
