About FlipaClipFlipaClip is the world’s biggest animation app with over +90 million lifetime installs.FlipaClip turns any mobile device into an animation studio.Animated movies and shows require massive budgets, years of production, or the approval of a handful of studios to exist. That’s how the industry has worked for decades.Very soon, a blockbuster animated movie will be entirely produced by a 15-year old in her parent’s basement. On a phone. And it will be made and distributed for $0. We are on it.Key ResponsibilitiesOwn the delivery and long-term operation of high-impact backend systems, from architecture to production.Set and evolve backend processes, engineering standards, and technical best practices.Define and actively use KPIs covering system reliability, development speed, data quality, and error rates.Make system-level architectural decisions and technical tradeoffs with a clear understanding of impact.Establish automated testing and validation processes that reduce regressions and operational risk.Introduce AI-assisted development workflows where they increase leverage, with strong validation and safety mechanisms.Communicate progress, risks, and technical decisions clearly across engineering and product stakeholders.Qualifications5+ years building and maintaining with AWSDemonstrable experience delivering high-impact backend systems and projects that operate successfully in productionStrong experience building backend services for mobile applications (iOS/Android)Ownership: Strong sense of ownership, strategic thinking, and a solution-first mindsetManagement: Creating structure where needed.
