We are looking for a highly skilled Senior Frontend Developer to join our tech team.
Overview
Collaboration is at the core of our organization. We are building a platform that enables co‑investment in the Private Equity sector and are focused on establishing both a premium brand and platform. As our tech team scales, you will wear many hats and play a key role in shaping the product.
Responsibilities
- Collaborate closely with the team on product strategy, assess effort required for features and make key technical decisions.
- Support overall decision‑making and the company’s sustained growth.
- Develop, deploy and maintain new features.
- Conduct code reviews and facilitate knowledge sharing within the team.
What You'll Work On
- Cap table engine: Build systems that track ownership across thousands of investors with cent‑level precision.

- Document automation: Generate legal documents (subscription agreements, shareholder reports) from dynamic templates.
- Security: Protect sensitive financial data with robust authentication, authorization and encryption.
Technical Challenges
- Precision at scale: Our engines compute fractional ownership across thousands of investors; rounding errors must cascade correctly.
- Complex financial state machines: Operations involve coordinated updates across multiple entities and ledger entries; state transitions must be atomic and auditable.
- Multi‑jurisdiction compliance: Different countries have different regulatory requirements; the system must enforce these rules programmatically while remaining flexible.
- Historical reconstruction: Auditors need to see data at any point in time; our architecture supports point‑in‑time queries tied to specific operations.
- Domain complexity: Model sophisticated financial instruments and multi‑currency valuations with type safety.
