What you’ll do:

• 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).

What we offer:

• Competitive salary and equity - you’ll share directly in the company’s success
