We ascribe to Netflix’s “Dream Team” culture and strive for every team member to be exceptional in their role and as teammates. Our team is remote across US time zones with quarterly in person meetups. Given this, the ability to operate autonomously is an absolute must.

• Are proficient with some backend language (we use Rust).
• You have first hand experience in deploying to AWS Cloud infrastructure.
• Thrive in dynamic environments, juggling multiple projects and navigating ambiguity with ease.
• Previous startup experience ideally, at a seed through series B startup.

Low Ego - You’re not above any task. You readily accept feedback and view it as an opportunity for growth. Collaborative - You thrive in team settings, naturally working across functions to drive the best outcomes for our customers. Hustler - You put in the effort required to make things happen.
