Job description
SDE 3 Requirements: • 5+ years of relevant professional full-time experience building backend systems. • Proactive self-starter capable of independently solving problems. • Ability to zoom out and think big picture in terms of architecture while simultaneously being able to get to granular details - seamlessly translating big picture to smaller details. • Hunger to build things and get things done. • Some exposure to FrontEnd (React, basic familiarity with a JS library + willingness to learn). • Some Big-Tech experience to know how systems are built in the ideal end state. • Some early-stage experience to know which parts of the end state matter and which ones can be compromised. (Or atleast a hunger to ship more after slow-moving Big Tech roles and curiosity to figure this out over time)
