Project Manager About Mappa Mappa builds real-time voice-AI infrastructure that decodes over 100,000 behavior patterns per person—based on prosodic and linguistic signals—and turns them into actionable insights for hiring and beyond. As we scale, we need a project manager with a tech-first mindset to help us deliver with speed, structure, and quality. Role Purpose Lead the execution of cross-functional projects across engineering, product, and QA. You’ll be responsible for keeping teams aligned, sprints on track, and deliverables up to spec—while ensuring functionality through hands-on testing and technical understanding. Key Outcomes (First 6 Months) Lead the successful delivery of at least 3 product or infra releases, on time and within scope. Implement and streamline a project tracking workflow using Linear and Agile best practices. Define and standardize delivery documentation across engineering and QA. Reduce cycle time per sprint by ≥ 20% through improved coordination and process clarity. Core Responsibilities Own project timelines, scope, and delivery across multiple squads. Manage day-to-day execution: standups, sprint planning, retrospectives, and backlog grooming. Coordinate closely with QA to ensure quality gates and testing coverage before releases. Review and approve deliverables, flagging risks or blockers early. Track progress and status in Linear; maintain visibility through reports and dashboards. Collaborate with Engineering and Product to define MVPs, acceptance criteria, and testable functionality. Contribute to light manual testing and validation, using your tech background to detect issues early. Facilitate post-mortems and retros to extract insights and refine team processes. Must-Have Skills 3–5 years of experience managing technical projects in software or AI/ML environments. Deep familiarity with Agile, Scrum, and iterative development practices. Experience using Linear, Jira, or similar project tracking tools. Strong communication and stakeholder management across tech and non-tech teams. Solid technical foundation—comfortable reviewing product functionality and working closely with QA. High attention to detail and proactive risk management. Fluent in English. Nice-to-Have Background in software engineering, QA, or product. Experience working with voice-AI, ML, or data-heavy pipelines. Exposure to remote-first or async team environments. Who You Are A structured operator who brings clarity and momentum to complex projects. You’re fluent in delivery—but not afraid to get your hands dirty testing a release or debugging a blocker. You keep people on track, processes lean, and timelines moving. Why Join Mappa Execution-critical role: Your coordination powers the systems we build. Tech-integrated: Work closely with engineers, QA, and product in a hands-on, fast-moving team. Remote-first: Join a distributed team across LatAm and the U.S.

QA / Test Automation Engineer Location: Remote (LatAm time zones preferred) Type: Full-time Reports to: CTO About Mappa Mappa builds real-time voice-AI infrastructure that decodes over 100,000 behavior patterns per person—based on prosodic and linguistic signals—and turns them into actionable insights for hiring and beyond. Quality and reliability are core to our product—and we’re looking for someone who ensures both scale with us. Role Purpose Design and maintain test automation systems that guarantee the stability, performance, and trustworthiness of Mappa’s voice-AI platform. You'll lead the creation of robust test cases, frameworks, and regression suites integrated with our CI/CD pipelines. Key Outcomes (First 6 Months) Implement automated test coverage for all core application components (frontend and backend). Reduce manual regression testing time by ≥ 60% via automation. Detect and prevent critical bugs pre-deployment in at least 90% of release cycles. Integrate testing into our CI/CD workflows and ship reliable builds multiple times per week. Core Responsibilities Design and implement end-to-end, integration, and regression test cases for web and backend components. Build and maintain test automation frameworks using Python, TypeScript, Selenium, Puppeteer, and PyTest/Bun. Integrate testing pipelines with CI/CD tools (Jenkins, GitHub Actions) for automated validation. Collaborate with Engineering and Product to define test plans and acceptance criteria. Monitor test coverage, identify gaps, and proactively improve testing strategies. Triage bugs, write detailed bug reports, and contribute to root cause analysis post-deployment. Maintain test documentation and ensure testing processes are well-documented and repeatable. Must-Have Skills 3+ years of experience in QA engineering or test automation.
