Software Development Engineer in Test (SDET)

We are looking to hire a Software Development Engineer in Test to design and implement automated tests across UI (Playwright), APIs (REST Assured and Postman), and performance (k6), integrated into CI/CD pipelines (GitLab preferred). The role requires experience with Docker/Compose, Java and TypeScript, shell scripts (bash), and validating results directly in the database using SQL. Strong knowledge of testing processes, defect lifecycle, and test design techniques (BVA, equivalence partitioning, decision tables, state transitions, pairwise) is essential.

Responsibilities

Build and maintain automated tests for web UI (Playwright), APIs (REST Assured with JSON Schema validation), and performance scenarios (k6).
Partner with product and engineering to clarify acceptance criteria, design for testability, review stories, and triage by severity and priority.
Own GitLab CI/CD: design and maintain .gitlab-ci.yml for testing purposes, use GitLab Runners (Docker executor), manage caching and parallelization, and keep pipelines green.
Publish and surface results in Merge Requests: JUnit XML test reports, Playwright HTML reports and traces, and k6 summaries as artifacts.
Use Docker and Docker Compose to containerize test tooling and spin up reliable local and ephemeral environments.
Deflake and harden suites: stabilize unreliable tests, tune retries and timeouts, and improve logs and tracing to raise signal-to-noise.
Shape test strategy (risk-based selection, test pyramid) to balance automation with exploratory and manual checks.
Document frameworks and guidelines; mentor developers and QCs on testing best practices.

Requirements

Hands-on with at least two of the following (and willing to learn the third):

Playwright (TypeScript/JavaScript): locators, fixtures, Page Object Model, trace viewer.
REST Assured (Java): RequestSpec/ResponseSpec, negative and edge-case testing, JSON Schema checks.
k6: smoke/baseline/load tests, thresholds such as p95.
CI/CD: contribute to automated quality gates by integrating tests, reports, and metrics into pipelines. Experience with GitLab CI/CD (.gitlab-ci.yml, jobs, caching, artifacts, and test reports) is preferred, though equivalent testing-related CI/CD experience (e.g., Jenkins or GitHub Actions) is also welcome.
Shell scripts (bash or equivalent).
Docker: Dockerfiles, Compose, local services for tests, basic container networking.
Programming: Java/Kotlin and/or TypeScript/JavaScript; solid OOP and clean code habits; Git workflow.
Database and SQL: write queries to validate system behavior and data integrity directly against the database.
Testing foundations: strong understanding of the software testing process, defect lifecycle, and severity vs priority; clear, reproducible bug reports.
Test design techniques: boundary value analysis, equivalence partitioning, decision tables, state transition testing, pairwise/combinatorial; with data-driven execution preferred.
Clear communication, collaboration, and time management; high attention to detail.

Preferred Qualifications

JaCoCo or other coverage tools for helper libraries; JSON Schema tooling.
UML basics; Postman or Insomnia; contract testing (for example, Pact).
Security testing exposure (OWASP); Dockerized local stacks (databases, queues, stubs).
Experience with GitLab features.
