About Katapult
Katapult is an AI-first engineering studio connecting senior LATAM talent with startups and companies in the US. We're not a staff-augmentation shop: every person we put in front of our partners represents Katapult, co-creates product, and owns the outcome directly, with no managers or leads acting as a layer in between.
About the Role
Fast growing fintech company that powers transactional workflows for lenders and financial partners, and is now investing in a new phase of product development: evolving from a transactional web platform into a verified, AI-driven architecture that increases throughput and reliability across its core workflows. This is a rare "second engineer" role for someone who wants deep ownership over a system's technical direction not just execution. You'll help design and build a modular platform covering document staging, AI-assisted validation, third-party verification, and fraud detection, replacing manual review processes with a combination of LLM-based and deterministic logic,



working closely with the founding engineering team and with high visibility to the executive team.
Responsibilities
Lead architecture decisions as the platform evolves from a transactional web application into an agentic, AI-enabled system
Design and build a modular pipeline covering document staging, automated rule-based validation, third-party verification, and fraud signal detection
Determine where LLMs add real value versus where deterministic, rule-based logic is more reliable, cost-effective, and auditable (e.g., document classification, compliance checks)
Build verification and evaluation pipelines with strong hallucination guardrails in a regulated, PII-sensitive environment where errors carry real consequences
Architect for extensibility toward future modules, including portfolio management and lender/buyer portals
Lay the technical groundwork for SOC 2 compliance without requiring a full rewrite
Collaborate closely with a small, senior foundi
