# Senior QA Engineer

**Tessera Labs** · Brazil

Salary: $50,000–$60,000 per year

Apply: https://jobs.ashbyhq.com/tessera-labs/95b583ad-b207-4d13-b475-36e9c2da71a4

## About the role

### Senior QA Engineer

**This is a fully remote job; preferred location is Brazil.**

#### The Role

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 Do

- Own 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.

#### What You'll Need (Required)

- 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).

#### Nice to Have

- 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.

#### What Success Looks Like (First 90 Days)

- 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.

#### Location and Work Model

Remote in Brazil
