Summary: Seeking a Senior/Staff Software Engineer to lead the technical direction and build a modular, AI-driven platform for a fast-growing fintech company, with high visibility to the executive team. Highlights: 1. Lead architecture of an AI-enabled system with deep ownership 2. Design and build modular AI/LLM-based verification pipelines 3. Collaborate directly with founding engineering and executive teams **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 founding engineering team, shipping autonomously and fast **What We're Looking For** * Advanced, conversational English.This role requires direct, daily communication with a US\-based executive team * 6\+ years of experience as a senior or staff\-level software engineer, with a track record of owning architecture in a growing startup * Proven experience building or evolving systems that combine AI/LLM components with deterministic, rule\-based logic * Hands\-on experience with verification/eval pipelines and techniques for reducing hallucination risk in production AI systems * Experience with document\-heavy workflows: extraction, validation rules, and integration with third\-party data sources * Strong experience with modern stacks such as Vercel and Supabase (or equivalent) * Experience in regulated, compliance\-sensitive environments (fintech, healthtech, or similar) is a strong plus * Comfortable working with high autonomy, fast iteration, and direct exposure to technical and executive stakeholders **Nice to Have** * Prior experience preparing a platform for SOC 2 certification * Experience with fraud detection systems * Experience in lending, capital markets, or structured finance technology **Work\-Life Balance** * **Work from Anywhere in Latin America:** Enjoy the freedom to work remotely from any country in Latin America. * **23 Days of PTO per Year:** Take time to recharge with paid time off, accrued monthly (1\.91 days/month). * **USA Federal Holidays** **Financial Benefits** * **Monthly Payment in USD:** Get paid in US dollars, no matter where you are. * **Contractor Agreement with No End Date:** Enjoy the stability of a long\-term contract.
