Responsibilities

• Test customer and supplier web applications across core workflows
• Validate user signup, login, part upload, file processing, printability analysis, supplier matching, RFQ creation, quote submission, and order flows
• Create and maintain QA checklists, test cases, and regression test plans
• Test across browsers, devices, file types, and edge cases
• Identify bugs, reproduce them clearly, and document expected vs. actual behavior
• Verify bug fixes before release
• Help maintain release quality as new features ship quickly
• Monitor production applications to make sure core workflows are online and functioning
• Watch for failed uploads, broken pages, API errors, background job failures, and unusual customer behavior
• Escalate critical issues quickly and help triage root causes
• Help maintain uptime and customer trust by catching issues before customers do
• Create simple internal dashboards or alerts for product health
• Review customer-uploaded files including CAD, PDFs, drawings, and part metadata
• Help assess whether parts appear suitable for 3D printing based on geometry, material, size, tolerance, and process constraints
• Flag common printability issues such as thin walls, unsupported features, overhangs, small holes, tolerance risks, warping risk, poor file quality, or missing information
• Work with engineering and domain experts to improve printability scoring and analysis workflows
• Help build internal printability review checklists and part-classification processes
• Compare automated printability outputs against human judgment and identify gaps
• Analyze how customers are using the platform
• Identify where users get stuck, abandon workflows, upload bad files, or fail to complete RFQs
• Review support issues, customer feedback, uploaded part data, and usage patterns
• Translate product usage observations into clear bug reports or product improvement suggestions
• Help the team understand what customers are actually trying to do, not just what the software says they did
• Create dashboards for product usage, customer activity, part uploads, RFQs, supplier responses, conversion funnels, and system errors
• Track key metrics such as: 1. Signups 2. Active users 3. Part uploads 4. Upload success/failure rates 5. File types uploaded 6. Printability analysis completion rate 7. RFQs sent 8. Supplier quote response rate 9. Customer drop-off points
• Use tools such as Google Analytics, PostHog, Mixpanel, Metabase, Supabase, SQL, or similar platforms
• Create weekly product quality and usage reports for the team
• Investigate bugs in the frontend, backend, APIs, database, or integrations
• Make small code fixes independently where possible
• Work with engineers on larger issues and provide clear reproduction steps
• Help improve error handling, logging, validation, and user-facing messages
• Review code changes from a QA and product reliability perspective
• Contribute to internal tools, scripts, dashboards, or automation

Skills

• 2–5 years of experience in QA, technical support engineering, product operations, analytics, or software engineering
• Strong ability to test web applications and document bugs clearly
• Basic full-stack development ability, ideally with TypeScript, JavaScript, React, Node.js, SQL, and REST APIs
• Ability to read code, debug issues, and make small fixes
• Experience with browser dev tools, logs, network requests, APIs, and databases
• Familiarity with analytics tools such as Google Analytics, PostHog, Mixpanel, Metabase, Looker Studio, Supabase, or SQL dashboards
• Strong attention to detail and ability to catch edge cases
• Comfortable working in a fast-moving startup environment
• Strong written communication skills
• Ability to work independently and escalate issues clearly
• Prior 3D printing experience is not mandatory, but the candidate should be excited to learn additive manufacturing quickly
• Familiarity with CAD files such as STEP, STL, 3MF, IGES, DXF, DWG, and PDFs
• Basic understanding of 3D printing processes such as FDM, SLS, MJF, SLA, and metal additive manufacturing
• Ability to understand mechanical parts, drawings, dimensions, tolerances, and materials
• Experience with slicers, CAD viewers, mesh repair tools, or 3D printing workflows
• Interest in manufacturing, automotive, aerospace, industrial parts, or physical products
• Experience with Playwright, Cypress, Selenium, Jest, or automated testing
• Experience setting up monitoring, alerts, or error tracking using tools like Sentry, Datadog, LogRocket, New Relic, or similar
• Experience with cloud platforms such as AWS, Azure, Render, Vercel, or Supabase
• Experience with GitHub, pull requests, CI/CD, and deployment workflows
• Experience with CAD, 3D printing, mechanical engineering, or manufacturing software
• Experience building dashboards or writing SQL queries
• Experience in a startup where responsibilities were broad and fast-moving
