* Design and build **highly scalable, secure, and reliable infrastructure** to support critical APIs, services, and data pipelines.

* Proven ability to design fault-tolerant, distributed systems at scale.
* Strong debugging and performance optimization skills across the stack.
* Exceptional collaboration and communication skills, with experience partnering cross-functionally.
* Startup mindset: Not scared of ambiguity and hungry for rapid growth

* Experience in payments, tax, accounting, or regulatory tech.
* Infrastructure or platform engineering background (e.g., CI/CD, observability).
