The Opportunity
At Iru, we're building something that matters, and we're doing it fast. In the age of AI, quality matters more than ever.
We're looking for a Senior SDET who doesn't just write tests… they build the systems, culture, and confidence that allows engineering teams to move quickly without risking our brand, image, or reputation. You'll be a force multiplier: someone engineers want to work with, who raises the quality floor across the entire product.
This isn't a role where you wait for tickets. You'll identify gaps, build the infrastructure, and own the outcome as you elevate quality holistically across multiple teams. If the idea of having genuine influence over how a late-stage startup ships software gets you excited, this is the role for you.
Day To Day
Design, build, and own end-to-end, integration, and performance test frameworks from the ground up and keep them healthy as the product evolves.
Partner closely with development teams early on to catch issues and drive testability upstream.
Integrate automated test suites into CI/CD pipelines, ensuring fast, reliable feedback loops that don't slow engineers down.
Investigate and triage failures with urgency and clear communication.
Champion testing best practices across engineering teams, through code reviews, pairing sessions, documentation, and leading by example.
Define and track quality metrics that give the team clear, honest visibility into the health of the product.
Proactively identify coverage gaps, tooling limitations, and process friction.
