This is a fully remote job; preferred location is Brazil.
We're hiring a Senior QA Engineer to own testing across our Software Development Life Cycle (SDLC). This is a strategy-and-automation role, not a click-testing one: you'll own the test strategy, write the test cases, and automate them on top of established open-source testing tools — working shoulder-to-shoulder with developers to bake quality in from the start rather than catch it at the end.
This role partners closely with application and platform engineering.
What You'll DoOwn the test strategy end-to-end across the SDLC.
Build and own test coverage on top of established open-source testing tools — defining the strategy, writing the test cases, and automating them — and integrate it into our Continuous Integration / Continuous Delivery (CI/CD) pipelines so tests run on every meaningful change.
Write clear, maintainable test cases and test plans, and keep them current as the product evolves.
Plan and run the full range of testing — including but not limited to integration testing, system testing, regression testing, and stress / load / performance testing.
Partner with developers to define acceptance criteria, shift testing left, and make quality a shared responsibility rather than a gate at the end.
Triage failures, drive root-cause analysis on escaped defects, and close the loop with durable fixes.
Report quality signals (coverage, flake rate, escaped defects) in a way the team can act on.
Strong test automation skills, with a track record of designing test strategy and automating it on top of established open-source testing tools.
Deep, practical understanding of the SDLC and where testing fits at each stage.
Proven experience writing test cases and test plans.
Hands-on experience across multiple testing types: integration, system, regression, and stress / performance.
Experience integrating automated tests into CI/CD pipelines.
Strong communication skills — you work directly with developers and can make a clear, persuasive case for quality.
Strong experience with Python, JS/TS
Familiarity with open-source testing tools (for example, Playwright or Cypress for end-to-end, pytest for unit and integration, k6 or Locust for load and stress testing).
Exposure to testing cloud or containerized (Kubernetes) workloads.
Experience supporting a System and Organization Controls 2 (SOC 2) or similar compliance program by producing test evidence.
Background in enterprise or regulated environments where reliability is non-negotiable.
Experience in early-stage environments where one person owns a broad testing surface.
You've assessed current test coverage and identified the highest-leverage gaps.
Automated test coverage is running in the pipeline on every meaningful change.
The team has a clear, lightweight process for triaging failures and preventing repeat defects.

What We Do
Enterprise transformations shouldn't take years or cost fortunes. At Tessera, we've built a multi-agent AI platform that cuts ERP transformation timelines from years to weeks and reduces costs by more than half—while delivering first-time-right outcomes with enterprise-grade security and governance. We combine the dependability of a trusted integrator with the speed of an AI innovator. Our vendor-agnostic platform is pre-trained on thousands of enterprise landscapes and hundreds of years of expertise, so it adapts to your environment from day one—harmonizing systems and data to deliver secure, governed execution across ERP and other critical systems. Unlike traditional system integrators, ERP vendor tools, AI point solutions, or in-house builds, Tessera delivers transformations that compress timelines by 90%, replace people-heavy manual work with intelligent automation, ensure systems and data harmonize correctly from the start, and avoid vendor lock-in through adaptive intelligence that evolves with your workflows. Tessera creates lasting change in how your processes and systems operate together. As the platform adapts to your environment and evolves with new data, you gain the confidence to modernize with less risk—freeing up resources to reinvest in growth rather than maintaining legacy complexity. Proven in regulated industries. Built for enterprise reality. Reshaping how organizations transform.
