We are looking for a Tech Lead — Quality Engineering Platform & AI to join our Dev Platforms team at MC Digital, and we believe we will be #betterwithyou!

What we expect from you…
• Roadmap and delivery — define the roadmap for QA platforms and tools, prioritize, and be accountable for milestones, adoption, and ongoing operation.
• Hands-on engineering — write code daily, design architecture, conduct code reviews, and solve the most complex technical problems.
• Technical leadership of 2–3 engineers — provide technical guidance, mentorship, and define the team’s engineering standards.
• Platforms and frameworks — reusable testing frameworks (E2E, integration, contract), CI/CD pipeline blueprints in GitHub Actions with pre-configured quality gates, internal tools, and dashboards.
• Performance, stress, and chaos engineering — platform-level performance/load testing as a service, structured stress testing practices, and the introduction of chaos engineering (frameworks, experiments, game days, safety mechanisms) integrated into pipelines and supported by observability.
• AI in QA practice — design and build specialized agents (test generation, coverage analysis, flakiness detection, failure triage), code skills/playbooks for Copilot and Claude Code, integrate assisted test generation into development workflows.
• Codified guidelines — define Quality Engineering guidelines and encode them into tools, templates, linters, and agents rather than passive documentation.
• Enablement and metrics — support teams in adoption, instrument quality and resilience metrics (DORA, defect escape rate, MTTR, SLO compliance), and produce actionable insights.

What you bring…
• ~10 years in QA/SDET, with substantial experience building frameworks and tools.
• Builder mindset and internal product focus; comfortable owning roadmap and delivery.
• Strong software engineering skills — design, clean code, architecture.
• Modern testing frameworks — E2E and integration (Playwright, Cypress), contract testing (Pact), and support for unit testing (xUnit/NUnit) via templates and agents.
• Hands-on performance and stress testing (k6, JMeter, Gatling) — methodology, baselines, pipeline integration.
• Chaos engineering — principles (hypothesis-driven, blast radius, steady state), tools (Chaos Mesh, Litmus, Azure Chaos Studio, Gremlin), and operational practice.
• Advanced CI/CD, ideally GitHub Actions.
• Assisted generation (Copilot, Claude Code) and, ideally, building agents/skills.
• DevOps/DevSecOps and observability (OpenTelemetry).
• Familiarity with the organization’s tech stack (.NET, React, Kubernetes, microservices, event-driven).
• Hands-on leadership of a small team — technical guidance and mentoring.
• Ability to influence Principals and Product Tech Leads without hierarchical authority.
• Clear technical communication, structured thinking, and pragmatic incremental delivery.
• Skills in Artificial Intelligence.

What we offer…
• Meal allowance on Dá Card;
• Telecommunications plan with voice, data, and equipment (for permanent employees);
• Flex it Up program — extra days off, unpaid leave, flexible work model (where applicable);
• Health and life insurance (for permanent employees) with the possibility of extending health insurance to family members under advantageous conditions;
• Flexible benefits program (where applicable);
• Onboarding and initial training plan, continuous training platform, and financial literacy program;
• School awards and merit scholarships for employees’ children, as well as holiday programs during school breaks;
• Baby welcome kit;
• Internal mobility programs to promote talent;
• Flu vaccine including administration (voluntary uptake);
• Somos Sonae program — psychosocial, financial, and legal support for employees;
• Ergocoaching sessions;
• Mental health promotion programs and nutrition consultations;
• Discounts and partnerships program with more than 300 brands;
