THE GAME PLAN
Everyone on our team has a part to play

Your work is consistently of high quality. You solve difficult problems, applying appropriate technologies and best practices. You work with your team to invent, design, and build software that is stable and performant. You are proficient in a broad range of design approaches and know when it is appropriate to use them and when it is not. Your solutions are pragmatic. You consider the legacy of the code you produce and write code that an Engineer unfamiliar with the system can understand. You limit the use of short-term workarounds. You do things with the proper level of complexity the first time (or at least minimize incidental complexity). You create flexible software without over-engineering. You make appropriate trade-offs, re-use where possible, and are judicious about introducing dependencies. You are efficient with resource usage (e.g., system hardware, database, memory/CPU, etc.).  

•    You own parts of product and technology & strive to become a subject matter expert.  

•    You write simple and extendable code following standards and best practices. You test your code thoroughly. You help balance customer requirements with the team requirements.  

•    You help your team evolve by actively participating in the code review process, design discussions, team planning, and support ticket reviews.  

•    You take on projects and make software enhancements that improve the team software and processes.  

•    You work to resolve the root cause of complex problems, leaving software better and easier to maintain than when you found it.  

•    You estimate stories/tasks accurately and deliver them in time. You keep yourself up to date with industry tools, utilities, and open-source frameworks.  

•    You participate in the interview process and help your team train other Software Engineers.

•    You will keep yourself up to date with market standards, open-source frameworks.

•    You participate in the on-call support rotation for your organization.

•    Most importantly, you are humble, pragmatic, self-managed, thirsty for knowledge, never satisfied and always challenging the norm. Responsible for the state of the code you both inherit and produce.
