Who are you?
You are plugged into the Ruby on Rails community and have fun dabbling in front-end technologies like Svelte too. Whether you’re sitting in the driver's seat leading a project from the technical conception to completion, mentoring developers, working with stakeholders, or supporting another technical lead - you’re equally at home, comfortable, and committed to the outcomes of the team. You adapt your communication to different audiences and ensure shared understanding when mentoring.. You are technically verbose, using tactically placed pauses or questions to check comprehension during mentoring, ensuring everyone is forming the same understanding. In technical review meetings, you are clear, accurate, concise, but not overconfident in your answers. Engaging with stakeholders, You can summarize key technical points clearly and effectively for stakeholders.
What you will do
Senior developers are the engine of change within DealMaker. Passionate about developing their craft, leveling up those around them, contributing to prioritization discussions, and enabling or making high-impact technical decisions in conjunction with peers.
Raising the bar of technical excellence: Never satisfied with the status quo, you are hungry to raise the bar of technical excellence. You bring fresh ideas based on community standards, understanding, and best practices into the organization with grace; advocating for their adoption but ultimately letting the ideas stand on their own merit. Peers look forward to giving you, and receiving from you, code reviews as they are often able to learn something new, or reinforce ideas they were unsure about. Your leaders trust you to practice and enforce the standards and best practices of the organization.
Speaking up: You are able to and willing to speak up whenever there is a concern or opportunity. Using GitHub’s request changes feature is as common to you as is working async or pairing with the author to work through your concerns. Similarly, you celebrate every time someone requests changes on your PR as an opportunity to learn. Your ability to tactfully combine constructive pushback with the expression “strong opinions weakly held” makes you a sought-after contributor to technical conversations. Balancing active listening and participation - you let others speak their mind and verbally work through an idea but are not quiet on a call.
Driving impact: There is a continuum between “done” and “perfect”, your ability to recognize where along that continuum a decision or implementation needs to be makes you a solid contributor of impact. You seek stakeholders confirmation when you are unsure, creating alignment. Your code contributions are done in thin slices of complexity, solving concise parts of a larger task making them quick to understand and review. You apply an impact-oriented approach when writing technical documentation, decomposing users stories or abstract initiatives into technical tasks making it easier for your colleagues and team mates to understand and implement.
Mentoring: Your approach to mentorship and guidance is rooted in building a shared understanding of the concept. You are patient and move at the speed of the mentee. You are empathetic, incrementally building understanding of complex or abstract computer science or language-specific concepts. Sometimes you are teaching from the front, demonstrating how to achieve an outcome. Often you are teaching from the back, letting the mentee drive, answering questions, and using questions to probe comprehension and understanding while guiding the mentee through the exercise.
