Work closely with designers to ship a beautiful app – they love to collaborate on getting the details right
plus, many of our customers are startups and appreciate our thoughtful, polished designs
Maintain a high quality bar – we provide banking services, so preventing crashes, errors, visual glitches, and wacky edge-cases is a top priority for us
