At Solink, our mission is to safeguard what matters most. We provide businesses with the tools to know sooner and act faster by transforming video security into real-time operational insights.

Our cloud-based platform integrates seamlessly with your existing cameras and systems, turning them into intelligent sensors that detect and interpret key moments. This empowers teams to make data-driven decisions, enhance security, and improve operational efficiency.

Trusted by over 30,000 locations across 32+ countries – including brands like McDonald’s and JYSK – Solink delivers clarity when it counts. Our solutions help businesses reduce shrink, optimize performance, and respond proactively to potential threats.

We're looking for a Software Development Engineer in Test (SDET) to join our Device Management team. This is an engineering role first: you’ll design and build test automation frameworks, tooling, and infrastructure that let the whole team ship confidently ’ll write real code against our Rust/Node.js APIs, our React front end, and our AWS serverless infrastructure to make the system testable, simulate device behavior at scale, and catch problems before they reach customers.

You’ll work as a peer to developers, contributing to architecture discussions, code reviews, and design decisions, with quality and testability as your lens.

You’ll have significant latitude to shape how the team approaches testing, from framework design to CI/CD integration to how we simulate thousands of IoT devices and video streams in a repeatable, automated way.

• Design, build, and maintain automated test frameworks and libraries spanning REST APIs, UI (React), security, and end-to-end/integration layers.
• Write production-quality code for test harnesses, device simulators, performance tools and mocks that emulate IoT device behavior and video streams at scale.
• Build and maintain tooling that improves testability across the stack — including for distributed, event-driven components (Lambda, DynamoDB, SQS, Kinesis).
• Integrate automated test suites into CI/CD pipelines, optimizing for fast, reliable feedback on every build and deployment.
• Evaluate and introduce new tools, frameworks, and approaches to keep test infrastructure scalable as the platform and team grow.

• Participate as a technical peer in design sessions, RFCs, and architecture discussions — advocating for testability, observability, and reliability from the start.
• Review code and pull requests with an eye toward correctness, edge cases, performance, and long-term maintainability.
• Work closely with backend and frontend engineers to understand system design and build automation that reflects real production behavior.
• Contribute to system reliability by supporting monitoring, alerting, and troubleshooting efforts, including issues involving device connectivity.

• Design test plans and strategies for new and existing features, deciding where automation adds the most value versus targeted manual/exploratory testing.
• Drive test coverage for IoT device configuration, monitoring, deployment, and connectivity workflows, as well as video playback, recording, and streaming features.
• Validate distributed cloud systems for correctness, performance, and resilience under realistic and edge-case load.
• Own test estimation and planning as part of sprint and release cycles, working directly with engineering leads.

• Act as a proactive voice for quality across the engineering org — identifying systemic risks early and proposing engineering solutions.
• Mentor other engineers and QA team members on automation practices, framework usage, and testable design.
• Provide direct, technically grounded feedback to developers and stakeholders when quality or architecture decisions are at risk.

Must-Have:

• 5+ years of experience in software testing with strong hands‑on coding…
