Senior Software Development Engineer in Test (SDET)

About this role

Senior Software Development Engineer in Test (SDET) (Remote, US-Based Only)
Build quality into software that matters.
At Pulsara, great testing requires more than finding defects or building automated tests. Our Senior Software Development Engineers in Test (SDETs) combine hands-on testing with software engineering expertise to build and sustain reliable automation, solve complex technical challenges, and mentor others while helping shape the team's approach to software quality.
And reliability matters here.
Pulsara is used by healthcare professionals coordinating care for time-critical patients. The defects you uncover, the automation you build, and the expertise you share help deliver software our customers can depend on when it matters most.
If you enjoy tackling complex testing challenges, improving how software is built and tested, and helping others succeed, keep reading.
What is Pulsara?
Pulsara connects people when seconds matter.
Pulsara is a secure, user-friendly software software solution that unites the entire care team, even across different departments or organizations. By replacing multiple phone calls, radio reports, faxes, and pagers with one unified patient channel, Pulsara streamlines workflows, leading to reduced treatment times, lower costs, and enhanced experiences for both patients and caregivers.
Who we are:
Pulsara is a 100% remote team made up of people with backgrounds in technology, healthcare, emergency services, business, and beyond, united by a common purpose: to improve the lives of people in need and those who serve them.
Working remotely gives us flexibility, but great remote work takes more than being able to work from home. We communicate intentionally, collaborate across teams, take ownership of our work, and depend on one another to follow through.
We are a company that continues to evolve. We value people who are curious, comfortable learning, willing to challenge how things have always been done, and interested in helping us make both our product and the way we work better.

What You’ll Be Testing

Pulsara isn’t a single web application.
Our technology environment includes:
📱 Native iOS and Android applications
💻 Web-based patient care, administration, and reporting tools
☁️ A highly scalable AWS cloud environment
🔌 Internal and public APIs
🗄️ Relational databases and complex data workflows
🔐 Secure, HIPAA-compliant systems supporting communication across organizations
That means testing often requires looking beyond a single screen or expected workflow. A change in one area may affect workflows elsewhere, and understanding those relationships is an important part of becoming effective in this role.
Your Primary Job Focus and Day-to-Day Activities Will Include:
⚙️ Build and sustain reliable automation
Design, develop, and maintain scalable automation frameworks and test suites that perform reliably over time. Improve test coverage, execution performance, and maintainability while minimizing flaky tests.
🔄 Strengthen testing tools and environments
Create, maintain, and troubleshoot test environments and supporting tools. Integrate automated testing into CI/CD workflows to help identify issues earlier and support dependable releases.
🔍 Plan and execute effective testing across the Pulsara platform
Develop practical test strategies, plans, and reusable test cases based on requirements, technical complexity, risk, and customer workflows. Perform manual and automated testing across mobile and web applications, internal and public APIs, database migrations, and tools running in AWS to identify defects, risks, and unexpected behavior.
🤝 Lead through technical expertise and mentorship
Share your experience designing and maintaining reliable automation to mentor other Test Engineering team members, strengthen their technical capabilities, and help shape the team's approach to testing and automation.
🧠 Think beyond the happy path
Explore edge cases, complex system interactions, and real-world conditions. Apply technical expertise and sound judgment to determine where automation adds value and where hands-on testing is essential.
🐞 Investigate and communicate problems clearly
Troubleshoot complex defects and test failures, document reproducible findings, collaborate on solutions, and verify fixes.
🏥 Keep the customer in focus
Understand how healthcare professionals use Pulsara and recognize where technical issues, unexpected behavior, or workflow friction could affect their ability to coordinate care.
🚀 Help us continuously improve
Identify opportunities to improve testing practices, automation, and tools. Apply new technologies, including AI-assisted tools, where they meaningfully improve quality and efficiency.
