SENIOR FULL STACK ENGINEER – INTEGRATIONS

Build the integration layer that connects enterprise compliance to the tools teams actually use.

About Haast

We're building one of the first agentic systems for enterprise legal and compliance teams that actually automates their manual work. End-to-end. Delivering 80% faster compliance reviews and 4x productivity gains.

We recently closed a $12M USD Series A (Peak XV Partners, DST Global, Airtree) and are ramping hard; building the infrastructure that will completely re-define how enterprises think about compliance.

- Architect our integration platform: APIs, webhooks, OAuth flows, and authentication standards that scale

- Ensure integrations surface our AI insights seamlessly into customers' existing workflows, fast, robust, and intuitive

- Make high-impact technical decisions quickly on integration patterns, third-party dependencies, and platform evolution

- You challenge "why" and "how" to ensure we are delivering the b...
