Senior Software Development Engineer in Test
Team: Engineering
Location: Miami
Commitment: Full-Time
Workplace Type: hybrid
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.
Minimum Qualifications:
- 5+ years of hands-on software development and testing experience, with deep expertise building and maintaining test automation frameworks at scale.
- Strong programming proficiency in one or more languages (TypeScript, Python, etc.)
- Demonstrated experience integrating automated testing into CI/CD pipelines (GitHub Actions, Code Fresh, Jenkins, CircleCI, or equivalent).
- Solid grasp of API testing, contract testing, and service-level validation across distributed or microservices architectures.
- A track record of meaningful cross-functional collaboration
- High ownership mentality — you treat quality as your personal responsibility, not a handoff.
Preferred Qualifications:
- Experience at a high-growth startup or late-stage company where ownership, proactivity, and rapid change is the norm.
- Familiarity with performance and load testing tools (Locust, k6, Gatling, or similar).
- Knowledge of observability tooling — logs, traces, metrics — and how to leverage them as a quality signal, not just a debugging tool.
- Experience with cloud infrastructure (AWS, GCP, or Azure) and container-based testing environments (Docker, Kubernetes).
- Mentorship experience — someone who has actively grown the testing capabilities of the engineers around them.
- An opinion on what good quality engineering culture looks like — and the ability to articulate and advocate for it clearly.
Who You Are:
- High ownership — You see a gap and fill it without needing to be asked twice.
- Collaborative by nature — Engineers seek you out early. You make them better at building.
- Go-getter — You move fast, bias toward action, and iterate in the open.
- Builder — You build frameworks that last, not scripts that barely work.
- Clear communicator — You can explain a flaky test to a PM and a CI bottleneck to a CTO.
- Resilient — Ambiguity doesn't stall you — it energizes you.
