Job description

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.
This role is both hands-on and strategic, requiring expertise in:
  • Playwright-based automation engineering
  • Distributed system validation (API, UI, data layers)
  • AI-assisted testing and automation practices

Responsible for transforming test automation into an AI-augmented quality system to enable:
  • Faster, reliable releases with solid understanding of CI/CD and modern DevOps practices
  • Strong regression signal with minimal noise
  • Scalable and maintainable test coverage across critical business workflows

Automation Strategy & Leadership
  • Own design and evolution of automation testing framework (primarily Playwright)
  • Establish best practices for E2E, integration, and regression testing
  • Drive test coverage across critical financial workflows (deal lifecycle, cash flows, reporting, etc.)
  • Mentor engineers and QA contributors; set test quality and maintainability standards

Hands-On Engineering
  • Build and maintain robust Playwright test suites (TypeScript/JavaScript)
  • Develop reusable testing utilities, fixtures, and CI/CD integrations
  • Implement parallelization, test isolation, and flakiness mitigation strategies
  • Integrate tests into CI pipelines (e.g., GitHub Actions, CircleCI)

Product & Domain Alignment
  • Translate complex financial workflows (e.g., loan servicing, covenant tracking, capital calls) into deterministic test cases
  • Validate data integrity across systems (APIs, databases, reporting layers)
  • Collaborate with product and domain experts to identify edge cases and risk scenarios

Quality & Reliability
  • Define SLAs for test reliability and pipeline performance
  • Monitor and improve test signal vs. noise
  • Introduce observability into testing (logs, traces, artifacts)
  • Lead incident retrospectives related to quality gaps

AI-Driven Testing & Development
  • Implement and scale AI-assisted test case generation from product requirements, user stories, and production data
  • Leverage LLM-based tools to generate, refactor, and maintain Playwright test suites
  • Build workflows for automated test creation, prioritization, and gap detection using AI
  • Evaluate and integrate tools for self-healing tests, intelligent selectors, and failure triaging
  • Partner with engineering to incorporate AI into broader development workflows (code generation, debugging, QA automation)
  • Establish guardrails and validation strategies to ensure correctness and determinism in AI-generated tests

Required Qualifications
  • 5+ years in QA automation, SDET, or software engineering roles
  • Deep expertise with Playwright (2+ years required) in production environments
  • Strong proficiency in TypeScript/JavaScript
  • Experience designing scalable test frameworks from scratch
  • Solid understanding of CI/CD systems and modern DevOps practices
  • Experience testing API-driven architecture and distributed systems

Domain Expertise
Previous experience in fintech, capital markets, or lending platforms.
Familiarity with:
  • Loan lifecycle and servicing
  • Private credit structures
  • Cash flow modeling and waterfall structures
  • Financial reporting and reconciliations

Nice-to-Have
  • Experience with data validation pipelines (SQL, dbt, etc.)
  • Exposure to backend languages (Python, Java, or Go)
  • Experience with performance or load testing tools
  • Familiarity with cloud infrastructure (AWS, GCP)

What Success Looks Like
  • High-confidence releases with minimal regression risk
  • Stable, fast CI pipelines with meaningful test coverage
  • Clear alignment between product logic and automated validation
  • Scalable testing culture embedded across engineering

Why Join
  • Build foundational infrastructure in a fast-growing private credit fintech
  • Work directly with domain experts shaping modern capital markets tooling
  • High ownership in a Series A environment with strong growth trajectory
  • Competitive compensation + equity
  • Strong understanding of financial systems-particularly within private credit, lending, or capital markets workflows
  • Define testing architecture, improve release confidence, and partner closely with engineering, product, and operations to ensure platform reliability in a high-stakes financial

What We Offer
  • Competitive salary + equity.
  • Healthcare coverage.
