Job description

Semrush is a brand visibility platform, empowering marketers to command their online presence and create measurable impact. We unify SEO authority and AI visibility, so brands are found, cited, and chosen everywhere search happens. That’s how Semrush gained the trust of over 28 million users—from scaling startups to Fortune 500 companies.

Here, you own the way you work, but we move as one unbeatable team.

We don’t just lead the market, we’re busy creating the world where Semrush is an unfair advantage for every marketer.

We move fast in ways to help you grow. Here, you have room to experiment, keep what works, and learn quickly from what doesn’t.

Ready to share our ambition and make an impact? Then, this role may be for you.

About The Role

• Build QA processes from scratch by establishing testing standards for a product team that doesn't yet have dedicated QA, embedding quality practices into sprint planning, backlog refinement, and the development lifecycle.
• Own quality across the product: take end-to-end responsibility for testing our Site Intelligence product, from customer-facing tools to the internal systems that support them.
• Build test automation: assess the current state of testing, select the tools and technologies best suited to the product, and design and implement a scalable test automation strategy and framework aligned with existing company-wide QA approaches.
• Lead backend API and UI test automation by designing, building, and maintaining automated test suites for backend microservices, asynchronous data workflows, and public and internal APIs.
• Validate complex cross-system integrations by testing data flows across multiple connected systems, including crawlers, internal configuration tools, metadata engines, and reporting APIs, to identify edge cases before production releases.
• Integrate automated testing into CI/CD pipelines by partnering with infrastructure teams to establish staging and release candidate environments and embed quality checks into the deployment process.
• Collaborate closely with product managers, engineers, tech leads, and cross-functional teams to align the testing strategy with product goals and engineering priorities - integrating QA within an established team of developers that owns testing on their side, without slowing down delivery.

About You

• Demonstrated experience building QA processes and test strategies from scratch within an active engineering team.
• Strong hands-on coding skills for test automation (e.g., Python), complemented by solid manual and exploratory testing experience. This is especially important in the early stages of the role, where deep investigation of systems and data flows will precede broader automation coverage.
• Solid experience testing public and internal APIs, backend microservices, distributed systems, and data pipelines.
• Practical experience integrating automated tests into CI/CD pipelines.
• Experience working with containerized environments such as Docker.
• Strong communication and collaboration skills, with the ability to work effectively across cross-functional teams.
• Fluent in English, both written and spoken.

Not required, but a plus

• Familiarity with Google Cloud Platform (GCP).
• Understanding of web technologies, web crawlers, or HTML structure.
• SQL skills for data validation and verification.

A Bit About The Team

The Vang team builds and maintains the core components behind our Site Intelligence product, including the Site Intelligence Crawl Orchestrator, Log File Analysis, and internal configuration tools such as the Platform JSON Editor and Elements Migration Tool.

Vang works closely with two key partner teams within Enterprise Solutions:

• Tim Team, which builds and maintains the enterprise website crawler using the Chrome/Lighthouse engine to analyze performance, usability, legal compliance, and accessibility.
• Viridian Team, which operates the cloud data pipeline powering Site Intelligence.
• Other Semrush teams, partnering on cross-system workflows and integrations.

About The Perks

• Unlimited PTO
• Hobby & team building budget allowance
• Employee Support Program
• Loss of family member financial aid
• Employee Resource Groups
