Principal Quality Engineer

About us:

Amach is an industry-leading technology driven company with headquarters located in Dublin and remote teams in UK and Europe.

Our blended teams of local and nearshore talent are optimised to deliver high quality and collaborative solutions.

Established in 2013, we specialise in cloud migration and development, digital transformation including agile software development, DevOps, automation, data and machine learning…

We are seeking a Principal Quality Engineer to join a product team responsible for multiple TypeScript-based web application and Backend-for-Frontend (BFF) services with complex business functionality. 

This is not a traditional QA position - we are looking for a senior, systems-thinking engineer who can take ownership of quality across the product estate from architecture and automation through to observability and production confidence. You will partner closely with the Tech Lead and engineering teams to define how quality is approached end-to-end. This includes mapping architecture and user flows, identifying critical use cases, strengthening release strategies, and ensuring deployments to production are both fast and safe. 

This is a hands-on individual contributor role within a small, high-impact team. You will shape the quality strategy while actively writing code, improving frameworks, and embedding engineering best practices. While the long-term vision is minimal-to-zero manual regression testing, you should be pragmatic and comfortable performing targeted manual testing early on where it adds value. 

Required Experience:

• Proven experience operating as senior or principal-level Quality Engineer, SDET or Quality Lead within modern web application environments 
• Strong proficiency working with TypeScript in production systems 
• Strong hands-on experience with automated testing frameworks such as Playwright, Cypress, Jest or similar 
• Demonstrated experience designing and improving test automation strategy across multiple services or applications 
• Experience embedding quality gates into CI/CD pipelines (GitHub Actions or similar) 
• Strong understanding of release strategies, deployment confidence, and rollback mechanisms 
• Experience working with AWS-hosted systems
• Solid understanding of observability principles and production monitoring 
• Comfortable operating strategically while remaining hands-on

Key responsibilities & duties include:

• Define and Drive Quality Strategy:
  • Co-create and implement a comprehensive quality strategy across multiple web apps and BFF services
  • Define principles for automation, production validation, and release confidence
  • Embed quality into architectural and design discussions early in the development lifecycle
• Automation First Testing: 
  • Design and implement robust automated test suites (unit, integration, API, and end-to-end)
  • Significantly reduce reliance on manual testing
  • Improve reliability, performance, and signal quality of automated tests
  • Integrate quality gates and reporting into GitHub-based CI pipelines (GitHub Actions)
• Operational and Production Quality: 
  • Leverage DataDog to define meaningful monitoring, alerting, and quality signals
  • Establish production health metrics, SLIs/SLOs, and release validation practices
  • Improve observability across applications hosted in AWS
  • Use production insights and feedback loops to continuously improve pre-production confidence. 
• Release and Deployment Excellence: 
  • Strengthen release strategies (e.g., progressive rollouts, automated validation, rollback mechanisms)
  • Improve confidence in cross-environment deployments
  • Embed automated checks and safeguards into GitHub CI workflows
• Engineering Enablement:
  • Coach engineers on testability, automation patterns, and ownership of quality
  • Improve system resilience and reliability through better engineering practices
  • Raise the overall quality bar across the product team

Desirable Experience:

• Experience working with DataDog or similar observability platforms 
• Experience with Terraform or Infrastructure as Code 
• Experience in microservices or distributed systems environments 

What’s in it for you: 

• An opportunity to join a fast-growing company  
• Options for career advancement 
• Learning and development opportunities 
• Flexible working environment
• Competitive salaries based on experience
