About PactFi

Private asset markets (PE, Private Credit, VC, Real Estate) have 10x to 9.8T in AUM over the past decade and are projected to grow to $17T in the next five years. However, digital infrastructure has not kept pace, with most of the market operating predominantly in error-prone, internal-only software solutions.

PactFi provides secure, end-to-end, operational infrastructure for managing complex private credit transactions. Our web-based application brings together all parties involved in such a transaction to more efficiently allocate capital, complete KYC, share documents, manage funds flow, and more. The platform is secured to a bank-grade standard, and we have received our SOC 2 Type 2 attestation.

PactFi was developed in close partnership with two of the industry’s largest players, both of whom represent the top 3 players in the private credit space by both size (AUM) and deal activity.

We are seeking a Senior Software Development Engineer in Test (SDET) to help scale end-to-end test automation for a modern fintech platform.
