You’re willing to tackle any and all challenges to ensure customer satisfaction, be it digging deep into a customer’s code-base, or helping to reconcile a tricky bill.
You’re proficient in communicating in a concise and technical manner, but also understand how and when to add verbosity when the situation calls for it.
You love problem solving, and take pride in helping customers and debugging issues even when it’s tricky or ambiguous.
You are comfortable writing code in at least one programming language (e.g., JavaScript, Go, Python, etc.), and you’re eager to deepen your technical skills over time.
