Want to land a tech job at Salesforce? If so, it’s essential to become as familiar as possible with the company’s core software product.

According to a Burning Glass analysis of Salesforce’s public job postings over the past 90 days, it’s clear that knowing how the Salesforce platform works is essential to many open jobs at the company. Mastery of Java, JavaScript, and Python is likewise helpful, as those are the programming languages that pop up most often in those postings. Check out the full chart:

That Salesforce would want its technologists to know the Salesforce platform should come as no surprise. At many companies, a grasp of an in-house technology is often crucial; for instance, knowledge of Azure will boost your chancesof landing a tech job at Microsoft. And like many other tech companies, Salesforce is likewise interested in technologists who have mastered some of the more common programming languages, tools, and development principles—good news for those who haven’t necessarily specialized in something more esoteric like machine learning or artificial intelligence (A.I.).

As offices across the country figure out how to safely reopen amidst the COVID-19 pandemic, Salesforce is taking a particularly flexible approach. Employees will have an option of flexible schedules (i.e., in the office 1-3 days per week), full-time remote, or fully office-based. “Our talent strategy is no longer bound by barriers like location, so we can broaden our search beyond traditional city centers and welcome untapped talent from new communities and geographies,” the company wrote in a lengthy blog posting explaining its policy. “And creating more flexible schedules removes hurdles that may make it more difficult to be in the office daily—from picking up kids to caring for sick family members.”
