Senior Software Development Engineer in Test

Construction is the 2nd largest industry in the world (4x the size of SaaS!). But unlike software (with observability platforms such as AppDynamics and Datadog), construction teams lack automated feedback loops to help projects stay on schedule and on budget.  Without this observability, construction wastes a whopping $3T per year because glitches aren’t detected fast enough to recover.
Doxel AI exists to bring computer vision to construction, so the industry can deliver what society needs to thrive. From hospitals to data centers, from foreman to VPs of construction, teams use Doxel to make better decisions everyday. In fact, Doxel has contributed to the construction of the facilities that provide many of the products and services you use everyday.
We have LLM-driven automation, classic computer vision, deep learning ML object detection, a low-latency 3D three.js web app, and a complex data pipeline powering it all in the background. We’re building out new workflows, analytics dashboards, and forecasting engines. Join us in bringing AI to construction!
We're at an exciting stage of scale as we build upon our growing market momentum. Our software is trusted by Shell Oil, Genentech, HCA healthcare, Kaiser, Turner, Layton and several others. Join us in bringing AI to construction!
The RoleJoin Doxel as a Senior SDET, driving quality in next-generation, local-first web applications. Lead automation efforts across real-time data processing and interactive frontends to ensure reliability and performance. If you're passionate about shift-left testing, automation, and embedding rigorous validation at every stage, this role is for you.
You will define and implement Doxel’s test automation strategy, ensuring scalability and reliability across frontend, backend, and data pipelines. Your expertise in CI/CD integration, performance testing, and security validation will enable seamless execution of AI-driven analytics, 360-degree video processing, and massive dataset handling. Your work will empower construction teams with precise, real-time decision-making tools.
Who You AreYou are obsessed with preventing issues before they arise, ensuring robust automation and infrastructure. You excel in complex systems, balancing client-side computation, real-time data, and backend integrations. You champion developer autonomy, mentor engineers, and build automation frameworks that enhance velocity without sacrificing reliability.

What You'll Do

• Own and scale test automation across frontend, backend, and data pipelines to support fast, reliable releases.
• Develop UI and API test suites that push the limits of performance using Three.js, DuckDb, and WebAssembly.
• Streamline CI/CD, integrating automated regression, load, and chaos testing for dependable deployments.
• Create and refine greenfield regression suites that evolve with the product.
• Embed automation early, ensuring testing accelerates development instead of slowing it down.
• Guide and support engineers in building a strong testing culture with practical, scalable best practices.

What You Bring to Doxel

• 4+ years in test automation frameworks (Playwright, Cypress, Selenium, PyTest, Jest, JUnit).
• 6+ years of hands-on coding in TypeScript, Python, or Java, building and extending test frameworks.
• Experience testing high-performance frontend applications (WebGL/Three.js, WebAssembly, client-side databases).
• Strong backend API testing skills, including database validation and large-scale data pipeline testing.
• Proficiency in CI/CD (GitHub Actions, CircleCI, Buildkite) and infrastructure-as-code testing.
• Knowledge of performance testing tools (k6, Locust, JMeter) and security best practices.
• Passion for developer productivity, reducing MTTD/MTTR.
• Bachelor’s degree in Computer Science or related technical field.
