Software Developer in test

Braintrust; Brasil; Presencial; BRL 110 000 - 170 000; Tempo integral

Resumo da oferta

Braintrust in Brazil seeks a skilled QA Automation Engineer focused on headless functional tests and Appium-based mobile UI automation. You will read specifications, design test plans, and implement maintainable C# tests within a CI-friendly workflow that embraces AI-assisted tooling and Loop Engineering.

The role requires hands-on coding in C#, real experience with automated tests, and the ability to debug flake versus product bugs.

Qualificações

• Must have real code-based automated tests written as code.
• Experience with UI automation across web/mobile is a plus.
• Ability to debug tests and distinguish flakes from defects.
• Familiarity with CI/CD pipelines and PR workflows.

Responsabilidades

• Write and maintain C# automated tests across survey flows.
• Review developer test PRs and request coverage.
• Triage CI/Stage failures: bug vs flake vs env.
• Decide what to automate at unit/headless/device UI/manual levels.
• Grow Appium coverage where the headless suite misses screens.
• Collaborate with Product, Architecture, and Dev for testable work.

Descrição da oferta de emprego

Role focus

• Primary: Headless functional test automation — fast, stable, and CI-friendly
• Secondary: Appium / device UI automation is an important layer, but not the entire role
• Spec-driven: Candidates will read and review specifications and test plans, not just work from tickets labeled "write tests"
• Manual coverage: A significant portion of our legacy coverage is still manual — candidates must also be comfortable executing and validating manual test cases as part of feature testing and regression efforts

How We Work

We use AI-assisted tooling (Cursor, AI code/test review, agent-driven test design) as part of daily workflow. We are adopting Loop Engineering — a structured process where docs, coding, QA, and DevOps run as coordinated loops with clear ownership, human gates, and agent participation. Candidates should be open to working alongside AI tools and contributing to a maturing engineering process.

What They Will Do

• Write and maintain C# automated tests for survey workflows (download, collect readings, GPS, export, settings)
• Review developer test PRs and send incomplete coverage back to engineering
• Triage failing CI / stage runs: product bug vs flake vs environment — then fix the ones that are ours
• Decide what to automate at which layer: unit / headless functional / device UI (Appium) / manual
• Grow Appium coverage where the headless suite cannot see the real screen
• Partner with Product, Arch, and Dev so new work is testable before it ships

This is not a record-and-playback role, and not a full-time manual tester who automates on the side.

Must-haves (do not send without these)

• Strong C# and comfort running tests from Visual Studio / command line
• Real experience writing automated tests as code (xUnit, NUnit, or MSTest)
• Page Object Model (or equivalent) — maintainable tests, not one giant script
• Can debug a failing test and explain flake vs product bug
• Git + pull-request review
• Clear written communication (Jira / PR comments)

Strongly Preferred

• Mobile UI automation: Appium, Espresso
• .NET MAUI
• GitHub Actions or Azure DevOps pipelines
• Async / timing issues (tests that race the app)

Nice to have

• GPS, Bluetooth, offline, or hardware-adjacent testing
• Field / inspection / GIS / industrial software
• Test design (what not to automate)
