Senior Software Engineer in Test building test frameworks and automation for IoT systems at Solink. Collaborating with teams to ensure quality and reliability in cloud-based solutions.
Responsibilities
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 (not just flagging bugs).
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.
Requirements
5+ years of experience in software testing with strong hands-on coding ability — this is a build-things role, not primarily a manual-execution role.
Strong programming skills in Python, plus working proficiency in TypeScript/JavaScript and/or Rust, sufficient to build and maintain real test infrastructure and tooling.
Demonstrated experience designing and building test automation frameworks from the ground up (API, UI, or integration layers), not just using existing ones.
Comfortable working in Linux environments.
Solid understanding of AWS services (Lambda, DynamoDB, SQS, Kinesis, or similar) and how they underpin distributed, serverless SaaS applications.
Experience integrating automated tests into CI/CD pipelines and treating test infrastructure as a first-class engineering deliverable.
Ability to read and reason about production code, participate meaningfully in code reviews, and collaborate with developers as a technical peer.
Strong systems thinking — able to reason about distributed, event-driven, and resilience-focused architectures.
Excellent communication skills, with the confidence to give direct, technically substantiated feedback to developers and stakeholders.
Bachelor's degree in Computer Science or a related field, or equivalent practical/engineering experience.
