Job description

Who We Are

Overflow is a Series C, growth-stage technology company on a bold mission: to inspire the world to give. We're a vertical fintech and SaaS platform unlocking more ways to give — cash, stock, crypto, and beyond — through a beautifully designed ecosystem built for high-impact churches, nonprofits, and mission-driven institutions.

Backed by Uncork Capital, Craft Ventures, Salesforce Ventures, R7, and WIF (one of the largest lenders to faith and philanthropic organizations in the country), we're building the infrastructure that makes generosity frictionless at scale.

Our Founding Principles

Overflow was founded on the belief that generosity transforms people and communities. Inspired by Proverbs 11:24 — "The world of the generous gets larger and larger" — we operate with integrity, stewardship, service, and excellence.

How We Work

Overflow operates with a flexible work model. While there is no company-wide in-office requirement, some teams may establish in-person collaboration rhythms based on their function, goals, and team needs.

We maintain offices in Los Gatos, CA and Birmingham, AL for team collaboration, coworking, meetings, and intentional in-person connection.

The Role

Overflow is hiring a QA Engineer to lead and champion quality across our product teams. In this role, you will not be the only person responsible for quality; you will be the force multiplier who enables the entire team to ship high-quality products with confidence.

What You Will Do

• Define and own the QA strategy: Develop and maintain comprehensive test plans, test cases, and holistic test strategies that blend automated and manual testing.

• Lead feature testing cycles: Personally conduct thorough exploratory, functional, and regression testing for all newly released features before they go to production.

• Partner with engineers: Collaborate with Product Engineers to review their test plans and ensure robust coverage across the entire test pyramid (unit, integration, and E2E).

• Maintain production quality: Conduct regular "production sweeps" and smoke tests (e.g., on Fridays) to proactively ensure all critical donor and nonprofit flows are fully functional.

• Champion the user: Be the primary advocate for the user experience, identifying edge cases, usability issues, and inconsistencies that automation might miss.

• Manage automation: Guide the expansion of our test automation coverage. You'll work within our automation frameworks (like Cypress) to run suites, analyze failures, and contribute to writing and maintaining tests.

• Bug & Defect Management: Identify, document, and meticulously track bugs, defects, and quality issues in our bug tracking system, and work with engineers to verify fixes.

• API Validation: Test and validate APIs to ensure data integrity, performance, and security.

• Advocate for Quality: Champion quality across the full SDLC, participating in planning and design reviews to identify risks and define acceptance criteria before development begins.

What You Should Have

• 5+ years of industry experience in a Quality Assurance or Software Test Engineer role.

• You are proficient in developing test plans and test cases from product requirements and design specifications.

• You have a deep understanding of manual and exploratory testing techniques and know when to apply them.

• You are comfortable working with test automation frameworks (e.g., Cypress, Jest). You can read, modify, and run tests, even if you aren't a senior-level developer, and are eager to help the team expand coverage.

• You have experience testing RESTful APIs and using tools like Postman or Insomnia.

• You are an expert with bug tracking tools (e.g., Jira/Linear) and version control systems (e.g., GitLab).

• You have a strong understanding of the SDLC, CI/CD pipelines, and agile methodologies, and excel at collaborating with developers on quality.

• You have a keen eye for detail, a strong sense of user empathy, and a passion for finding elusive bugs.

• You have excellent communication skills to clearly articulate bugs, test results, and quality risks to both technical and non-technical stakeholders.

Our Compensation Philosophy

The base salary range for this position is $120k – $170k, based on Carta Total Compensation benchmarks for role, geography, and function. Total compensation may also include equity, performance-based bonuses (for eligible roles), and a comprehensive benefits package.
