Senior Stack Tester information

What is a senior stack tester?

Senior Stack Testers are experienced professionals responsible for conducting tests and inspections on emission sources, such as industrial stacks, to ensure compliance with environmental regulations. They use specialized equipment to collect and analyze samples of gases, particulates, and other pollutants released into the atmosphere. Senior Stack Testers typically lead testing teams, oversee safety protocols, interpret test results, and generate detailed reports for regulatory agencies. This role requires strong technical knowledge, attention to detail, and familiarity with environmental standards like the EPA’s Method 5.

What are the key skills and qualifications needed to thrive as a senior stack tester?

To thrive as a Senior Stack Tester, you need deep knowledge of software testing methodologies, quality assurance processes, and solid experience with full-stack application architectures. Familiarity with test automation tools (like Selenium or JUnit), CI/CD systems, and scripting languages is typically required, along with relevant certifications such as ISTQB. Strong problem-solving skills, attention to detail, and effective communication help you collaborate across development teams and catch subtle defects. These competencies ensure robust, scalable, and reliable software releases in complex enterprise environments.

What are some common challenges faced by senior stack testers when working with complex, multi-layered applications?

Senior Stack Testers often encounter challenges such as ensuring end-to-end test coverage across both front-end and back-end systems, managing rapidly evolving tech stacks, and troubleshooting elusive integration issues. Coordinating with development, DevOps, and product teams to address dependencies and maintain test environments can also be demanding. Staying up to date with the latest testing tools and frameworks is essential for maintaining efficiency and accuracy in such a dynamic role.

The main difference between a Senior Stack Tester and a Stack Tester lies in experience, certifications, and responsibilities. Senior Stack Testers typically have more advanced skills, leadership duties, and work on complex projects, whereas Stack Testers focus on executing tests and reporting issues. Both roles are essential in the testing lifecycle, but the senior position requires more expertise and oversight.

Job Description:
Our Opportunity:
Chewy's Sponsored Ads business is growing rapidly, and we're looking for an experienced Senior Full Stack Engineer to help drive the evolution of our advertising platform. This role focuses on building scalable, high-performance systems that power key ad capabilities for both advertisers. You'll lead frontend development efforts, mentor junior engineers, and play a critical role in shaping one of Chewy's fastest-growing revenue streams.
As an experienced Software Engineer with a background in frontend and full-stack development. You excel in working on backend and frontend services with technologies like Typescript, Python, Java and both SQL/NoSQL databases. You have expertise in CI/CD pipelines (Jenkins), cloud environments (AWS), and authentication services.
Your hands-on experience and track record ensure you can build and ship new applications or features to existing applications, quickly and efficiently.
Launched in 2022, Chewy's Sponsored Ads platform enables vendors to promote their products on-site and offsite, significantly contributing to Chewy's revenue growth. The Ads Demand team owns the frontend and backend of the Advertiser portal which enables advertisers create, manage and optimize their ad campaigns. We are based in Boston and Seattle.
What You'll Do:
  • Lead project delivery and system architecture for full stack services, while mentoring junior engineers and promoting engineering excellence across the team.
  • Design and implement scalable, low-latency services in Typescript, Java, Python, powering core advertising capabilities such as auction processing, targeting, and performance tracking.
  • Develop robust and well-documented RESTful APIs to support campaign management, reporting, and integration with advertiser-facing tools.
  • Build resilient systems with strong observability, leveraging automated testing, monitoring, and CI/CD pipelines using infrastructure-as-code tools like Terraform.
  • Collaborate closely with product managers, data scientists, and fellow engineers to build systems that support real-time and asynchronous workflows.
  • Drive technical design reviews, conduct code reviews, and lead initiatives to improve platform reliability, performance, and scalability.
  • Take ownership of project estimation and delivery, partnering with stakeholders to deliver high-impact features that enhance the advertiser and customer experience on the Chewy Ads platform.

What You'll Need:
  • Bachelor's degree in Computer Science or related field (or equivalent experience).
  • 5-10 years of experience as a Software Engineer, with a strong focus on backend development using modern languages and frameworks including Typescript, Java, Python, SpringBoot, NextJS and React
  • Proven experience building scalable, highly available systems.
  • Experience integrating AI/ML models working alongside Data Science team.
  • Ninja coding and debugging skills
  • Passion for data-driven development, observability, and metrics.
  • Knowledge of professional software engineering practices including coding standards, code reviews, source control, build processes, testing, and operations
  • Solid understanding of CS fundamentals: object-oriented design, algorithms, and problem-solving
  • Excellent verbal and written communication skills.

Bonus:
  • Experience in Ad Tech and/or e-commerce.
  • Experience with Scrum, XP or other agile methodologies.
  • Experience with full stack development
  • Familiarity with AWS cloud services, including serverless computing, data processing, and storage solutions.

  • The specific salary offered to a candidate may be influenced by a variety of factors including but not limited to the candidate's relevant experience, education, and work location. In addition, this position is eligible for 401k and a new hire and annual equity grant. C08+ positions may also be eligible for annual bonus.

We offer different types of insurance and benefits, such as medical/Rx, vision, dental, life, disability, hospital indemnity, critical illness, and accident. We offer parental leave, family services benefits, backup dependent care, flexible spending accounts, telemedicine, pet adoption reimbursement, employee assistance program, and many discounts including 10% off pet insurance and 20% off at Chewy.com.
Exempt salary team members have unlimited PTO, subject to manager approval. Team members will receive six paid holidays per year. Team members may be eligible for paid sick and family leave in compliance with applicable state and local regulations.
