What does a Jr Test Engineer do?

A Jr Test Engineer is responsible for assisting in the testing of software or hardware products to ensure they meet quality standards before release. Their tasks typically include writing and executing test cases, identifying and reporting bugs, and collaborating with developers to resolve issues. Junior Test Engineers often work under the guidance of senior team members and help document test results. This entry-level role is a great way to gain experience in quality assurance and learn about software development processes.

What types of projects or products does a Jr Test Engineer typically work on, and how do they fit into the broader engineering team?

Jr Test Engineers are often involved in testing software applications, hardware devices, or integrated systems, depending on the company's focus. They typically work closely with developers, QA analysts, and product managers to execute test plans, identify bugs, and verify fixes. This role is essential for ensuring product quality before release, and Jr Test Engineers often participate in daily stand-ups and sprint reviews as part of an Agile team. Collaborating with more senior engineers, they gain exposure to industry-standard tools and methodologies, which helps build a strong foundation for future career growth within the QA or development tracks.

What are the key skills and qualifications needed to thrive as a Jr Test Engineer, and why are they important?

To thrive as a Jr Test Engineer, you need a basic understanding of software testing methodologies, familiarity with programming or scripting languages, and a relevant degree in computer science or engineering. Experience with testing tools like Selenium, JIRA, and test management systems, along with certifications such as ISTQB Foundation, are commonly required. Attention to detail, problem-solving abilities, and effective communication help distinguish top performers in this role. These skills and qualifications are crucial for ensuring software quality, identifying defects early, and supporting efficient team collaboration.

What is the difference between Jr Test Engineer vs QA Tester?

AspectJr Test EngineerQA Tester
Required CredentialsTypically a diploma or degree in Computer Science or related fieldSimilar educational background, often with certifications in testing
Work EnvironmentInvolves manual and automated testing, often collaborating with developersPrimarily focuses on executing test cases and reporting bugs
Employer & Industry UsageUsed in software development companies, tech firms, and IT departmentsCommon across software, gaming, and app development industries

The main difference is that Jr Test Engineers often participate in designing test plans and automation, while QA Testers primarily execute test cases and report issues. Both roles require similar skills and certifications, but Jr Test Engineers tend to have broader responsibilities in testing processes.

Our tools and platform are used by thousands of users and consumers.We own a modern full‐stack architecture including **TypeScript/React, Python, GraphQL, Golang**, and **ML model services**, which powers data‐annotation pipelines and machine‐led training data solutions at **foundation‐model scale**. We partner closely across **AI/ML engineers**, **Product Operations**, **Product Management**, **Data Science**, and other **ML Platform** groups.This role is ideal for an engineer looking for end-to-end ownership of meaningful pieces of the platform, growth in technical and strategic leadership, and direct impact across teams and systems that unblock the next generation of AV capabilities.### ### **What You’ll Do*** **Define the platform vision and roadmap** Work with cross-team and cross-functional leads to understand current and future needs, translating their input into an aligned platform vision and an incremental development roadmap.* **Own projects end‐to‐end** Take ownership of technical projects from problem framing through design, implementation, and rollout. Drive code reviews, design discussions, and technical decisions.* **Collaborate across the AV stack** Work with partner teams (ML Engineering, Operations, Product, Data Science, other platform teams) to translate abstract requirements into concrete workflows, APIs, and UIs that hit quality, cost, and latency goals.* **Level up how ML teams work with data** Develop automation and tooling that give ML engineers deep insight into labeling workflows and data quality (e.g., efficiency dashboards, auto‐QA, autolabel review tools), reducing iteration time from idea to trained model.* **Apply ML to labeling itself** Collaborate with ML engineers to design and integrate ML‐driven data annotation (pre‐labeling, autolabeling, active learning loops), helping us move from human‐only to machine‐led labeling at scale.* **Build high‐impact labeling experiences** Design, implement, and test scalable, high‐performance user experiences and services using modern full‐stack and/or frontend technologies. You’ll help the team ship features spanning multiple surface-areas that directly affect how quickly and accurately we can label data for new models and cities.* **Champion AI‐assisted engineering** Use and advocate for modern AI‐powered development workflows (code assistants, automated documentation, test generation, etc.) to increase build-velocity while maintaining code and product quality.### ### **Your Skills & Abilities*** Passionate about **self‐driving/robotics technology** and its potential to transform safety, mobility, and the human experience.* Proven experience **shipping and operating** end‐to‐end products or features in production.* Strong **communication and collaboration** skills; you can explain tradeoffs, influence peers, and work through ambiguity with cross‐functional partners.* Driven to **learn new technologies** and deepen your expertise across frontend, backend, and data/ML‐adjacent systems.* Empathetic to user challenges (from labelers to ML engineers to Ops) and excited to turn messy workflows into **simple, intuitive tools**.## ## **Requirements*** **8+ years** of experience building robust **distributed platforms and applications**.* Hands-on experience **leveraging AI tools** (agentic workflows, knowledge acquisition, documentation generation, operational triage, etc) to accelerate understanding, implementation, debugging, and delivery of new capabilities.* Proficiency in writing and reviewing high‐quality, scalable, and performant full-stack code using technologies and languages like **Python, TypeScript, Go, React, SQL, Redux, gRPC, GraphQL, WebGL, etc**.* Solid understanding of **scalable software system design** including data modeling and API/interface design.* Strong fundamentals in **object‐oriented design and design patterns**, **data structures**, **algorithms**, and engineering best practices (TDD, code quality, observability, CI/CD).### ### **Bonus Points*** A track record of close collaboration with **customers**, **product managers**, **designers**, and/or **user experience researchers**.* Experience with **computer vision**, **machine learning**, or data‐centric AI projects — especially where data annotation, data quality, or autolabeling loops were central to the work.* Familiarity with **data labeling/annotation platforms** or tools used by large labeling workforces (e.g., annotation UIs, workflow engines, quality systems).* Experience with **A/B testing** and **telemetry/observability** systems to measure impact and reliability.* Experience developing data‐intensive or visualization‐heavy applications.**Compensation:** The compensation information is a good faith estimate only.
