## Job description

## About SIMBA Voice Agents by Speechify

SIMBA lets companies deploy natural, human-sounding AI voice agents in 71+ languages with sub-second latency. We don't just hand customers a product and wish them luck — every customer gets a Forward Deployed Engineer who builds their agents, joins their Slack, and iterates with them weekly. We're building the future of voice AI, and we're looking for someone who can sell that vision and help bring it to life.

## Overview

Our team is committed to changing the way people read and with our exponential growth, we are looking for a strong QA engineer to help us for our SIMBA Team. We love a commitment to quality and risk assessment, maintaining documentation, and curiosity of testing trends and industry standards.

This is a full-time remote role and can be based anywhere globally.

## What You’ll Do

- Develop and execute detailed manual test plans and test cases for the SIMBA Team, ensuring strong functional coverage across core user flows and edge cases.
- Perform hands-on manual testing across browsers and devices to validate new features, bug fixes, and releases.
- Collaborate closely with engineers and product teams to identify, reproduce, isolate, and document defects, providing clear steps, expected vs. actual results, and supporting evidence.
- Maintain clear and organized QA documentation, including test cases, regression suites, test reports, and release validation summaries.
- Partner with Product, Engineering, and Customer Support to ensure issues are triaged correctly and prioritized based on user impact.
- Participate in Agile workflows including daily standups, sprint planning, grooming, and retrospectives, ensuring QA is embedded throughout the development lifecycle.
- Execute regression testing and release validation to ensure product quality and stability prior to launch.
- Continuously identify ways to improve manual QA processes, test coverage, and communication between teams.

An ideal candidate should have

- B.S. in Computer Science, related technical field, or equivalent experience
- 3+ years of experience in manual QA testing, with a strong focus on Web applications
- Strong understanding of QA fundamentals including test planning, test case design, regression testing, exploratory testing, and bug reporting
- Experience working in Agile environments and collaborating cross functionally with engineering and product teams
- Excellent troubleshooting and problem-solving skills, with the ability to isolate root causes and communicate issues clearly
- Strong written communication skills, especially when documenting defects and test results
- Familiarity with tools like Jira, Linear, or similar bug tracking/project management systems
- Experience using browser developer tools to assist with debugging and issue reproduction

Nice-to-Have:

- Experience with accessibility testing and familiarity with WCAG guidelines
- Familiarity with text-to-speech technologies or audio-based products
- Exposure to test automation tools (even if not responsible for building automation)
- Experience validating APIs using tools like Postman

- Sell a product that genuinely impresses prospects — sub-second latency and 71+ languages speaks for itself
- High ownership role with direct input on GTM strategy and positioning
- Work alongside a team that stays embedded with customers, so you're never selling something that doesn't deliver
