Experience with Kafka or other messaging platforms, investment systems or financial services would be useful. You don’t need to meet every requirement to apply. If this role interests you and you bring relevant experience, we’d like to hear from you.
And one more thing: research shows that women and members of underrepresented groups often only apply if they meet 100% of the requirements. Does this sound familiar? If so, we encourage you to apply anyway. We look forward to meeting you! Check out our diversity policy here.
