Job Description

Here at Side, we are seeking a Senior Test Engineer with strong technical and analytical skills to support the testing and quality assurance of our large language model (LLM) and related applications. This is not a crowd-sourced or entry-level QA role, rather, it’s a hands-on position suited for a professional who can operate autonomously, identify gaps, and maintain a high-quality testing standard across a fast-moving development environment. You’ll work closely with engineering and product teams to validate new features, perform regression testing, and ensure smooth functionality across both user-facing and backend systems. A general understanding of LLMs and related APIs is essential, as well as comfort with developer tools and technical testing environments.

Key Responsibilities:

• Execute functionality, regression, and new feature testing for ongoing LLM-driven product releases.
• Design, document, and maintain comprehensive test cases and testing frameworks.
• Perform UI/UX testing to ensure smooth and intuitive product interactions.
• Validate API endpoints, keys, and developer integrations to ensure consistent system behavior.
• Review and manage bug reports submitted by offshore QA teams, verifying, reproducing, and escalating as necessary.
• Collaborate with engineering teams to track issues through resolution and ensure quality standards are met prior to release.
• Provide testing insights to improve QA efficiency, automation coverage, and release confidence.
• Stay up to date on LLM behavior, capabilities, and limitations to design effective test strategies.

Requirements

Qualifications & Experience:

• 5+ years of experience in Quality Assurance or Software Testing, preferably within AI, SaaS, or developer tooling environments.
• Proven experience creating and executing test cases, managing test cycles, and validating both frontend and backend functionality.
• Familiarity with large language models (LLMs), generative AI systems, or NLP products.
• Strong understanding of API testing and developer tools (Postman, Swagger, cURL).
• Experience with bug tracking systems ( Jira, TestRail, or similar).
• Solid grasp of software development lifecycles and QA best practices.
• Strong analytical and communication skills, with the ability to work independently and manage multiple priorities.

Bonus Points:

• Experience testing AI-integrated user interfaces or chat applications.
• Familiarity with Python, JavaScript, or other scripting languages for automated or semi-automated test setups.
• Knowledge of CI/CD pipelines and QA automation tools.

Benefits

• This position is tied to a defined project. The engagement length is estimated at 6 months as a W2 Contractor.

• Gain hands-on experience with technical troubleshooting and gaming platforms 
• Be part of a collaborative, fun, and supportive team environment
