Sr. Software Engineer, Test (Software Development Engineer Test)

Ledgebrook is an AI-native specialty insurance platform. When a business needs coverage that is custom and complex, its broker comes to us, and our underwriters give them an answer, often in hours rather than weeks.

We built our technology from scratch, with AI in it from the first line of code. The technology helps price the risk; the underwriter uses their judgment to decide. There are always two hands on the wheel.

We are insurance industry insiders, and we eat our own cooking: Ledgebrook writes the policy and shares the risk through our own carrier, Ledgebrook Specialty, rated A- (Excellent) by AM Best. We work exclusively through wholesale brokers.

Our vision: to make the wheels of insurance spin faster.

At Ledgebrook, everything we do is driven by our culture: Care, Strive, Thrive Together. To succeed in modernizing the industry, we must first succeed in changing the way we do business. Talent density is our north star—fewer, better people working together as one. To that end we’ve replaced all individual incentives with generous equity packages—we play as a team, we win as a team. Everyone benefits handsomely from Ledgebrook’s success.

About the Role

We are seeking a meticulous Quality Assurance Engineer to join our dynamic team and take ownership of ensuring the quality and reliability of our software products. As a Quality Assurance Engineer, you will play a crucial role in designing, implementing and executing test strategies, executing test plans, and collaborating with cross-functional teams to keep and improve the automation coverage and identify and address eventual defects. This is an exciting opportunity to contribute to the development of groundbreaking insurance solutions in a fast-paced startup environment.

What you’ll do

Architect Automation Frameworks: Design, develop, and maintain scalable automated testing frameworks using Playwright and TypeScript/JavaScript.

Implement Design Patterns: Apply industry-standard test design patterns (e.g., Page Object Model, Screenplay Pattern, App Actions, or Singleton) to ensure a maintainable and robust codebase.

Optimize CI/CD Integration: Integrate automated suites into CI/CD pipelines to provide rapid feedback loops for the engineering team.

Technical Collaboration: Partner with Software Engineers during the design phase to advocate for "testability" and influence the development of features from the ground up.

Advanced Locator Strategy: Develop and enforce sophisticated locator strategies to ensure test stability and reduce flakiness across dynamic web applications.

Quality Analytics: Analyze test execution data to identify quality bottlenecks in any of the application areas and provide actionable insights to the team.

Version Control Mastery: Manage test code through Git, participating in code reviews to ensure the quality of the automation suite itself.

Continuous Quality Improvement: Continuously identify opportunities to enhance testing processes and improve efficiency.

Documentation: Document test procedures, test results, and defects in a clear and concise manner.

Living Documentation & BDD: Advocate for and implement Behavior-Driven Development (BDD) using Gherkin syntax to create "living documentation." Transform requirements into executable specifications that clearly communicate test procedures, results, and defects to both technical and business stakeholders.

Strategic Manual Testing: Conduct targeted manual or exploratory testing when necessary, primarily for new feature discovery or complex edge cases that aren't yet ready for automation.

Be a Team Player: Be always proactive, participate in Agile development processes, including sprint planning, daily stand-ups, and sprint reviews.

Mentor Developers: Partner with software engineers to provide training and guidance on writing effective unit, integration, and smoke tests, elevating overall code quality and reducing downstream automation needs.

Product Roadmap Alignment: Collaborate closely with Product Managers to review upcoming features and roadmaps, proactively designing test strategies that anticipate new functionality and ensure seamless quality coverage from the outset.

About you

Here at Ledgebrook we are passionate about creating a team that is on a continuous learning journey and that shares our excitement about building a company from the ground up. We don’t just want someone to follow a checklist; we want a builder who is:

• Innovative: You aren't satisfied with the status quo and constantly seek to optimize test execution time and reliability.
• Growth-Oriented: You have a hunger for mentorship and staying current with the evolving JavaScript/TypeScript ecosystem.
• Agile & Urgent: You balance the "keener sense of urgency" with the architectural discipline to "do it right" the first time.
• Principled: You hold yourself and your code to high standards, maintaining a "do the right thing" mentality in a high-performing, non-toxic environment.
• Proactive: A strong drive and desire to win together as a high-performing team
