About the Role
We are building the future of HR Tech.
As an Agentic AI Software Engineer – Test, you will own quality across the entire product stack, from AI-driven automated pipelines to hands-on manual validation. Your goal is to ensure everything we ship works exactly as customers expect.
This role sits at the intersection of AI, quality engineering, and product thinking. You will work closely with customers, understand real-world use cases, and translate them into robust testing strategies.
You will build intelligent test agents, automate end-to-end workflows using Playwright, and act as the final quality gate before every release.
What You’ll Do
AI Agent Development
- Design and build AI agents that autonomously test product changes and detect regressions
- Integrate AI-driven testing into CI/CD pipelines for fast, intelligent feedback on PRs
- Improve prompting, evaluation logic, and tooling to increase coverage and reduce false positives
Customer & Product Alignment
- Act as the quality advocate between customers and engineering
- Understand customer workflows and translate them into clear acceptance criteria
- Identify edge cases, gaps, and testability issues early in the development cycle
- Ensure shipped features match customer expectations
Automation Testing (Playwright)
- Build and maintain scalable end-to-end test suites using Playwright
- Create reusable frameworks, page object models, and utilities
- Integrate tests into CI/CD with strong reporting, traces, and debugging tools
- Monitor and fix flaky tests to improve reliability
Manual Testing & Release Validation
- Perform exploratory and structured testing before releases
- Create test plans aligned with real customer scenarios
- Execute regression, smoke, and edge-case testing across environments
- Track and document bugs with clear reproduction steps
What We’re Looking For
Technical Skills
- Strong experience with Playwright for browser automation
- Solid programming skills in JavaScript (Node.js)
- Familiarity with AI-driven tools or LLM-based systems
- Understanding of APIs, backend systems, and debugging workflows
- Experience with CI/CD pipelines
- Proficiency with Git and PR-based workflows
Professional Skills
- Strong customer empathy and communication skills
- Ability to translate requirements into testable outcomes
- Experience with manual and exploratory testing
- Ability to work independently across multiple workstreams
- Why Join Us
- Flexible remote / hybrid work setup
- Health coverage
- Opportunity to build at an early-stage, high-growth AI company
- High ownership and direct impact on product quality
- Collaborative team that values craftsmanship, customer empathy, and transparency
This is a hands-on engineering role. You should be comfortable writing and maintaining production-quality code and building robust automation, not just executing manual tests.
