Software Engineer, Quality & Release Engineering

IDEXX•Westbrook, ME

4d•$125,000 - $135,000•Onsite

About The Position

IDEXX Payments is seeking a Software Engineer who specializes in quality, automation, and release confidence to help advance how we validate and ship mission‑critical payment systems. This is a hands‑on engineering role focused on building scalable automated testing capabilities, strengthening release safety, and enabling teams to deliver changes confidently in a regulated, cloud‑native environment. This is not a manual QA or test‑execution role. It is an engineering position with ownership over test architecture, automation frameworks, and quality enablement. You will work closely with software engineers to embed automated testing and release validation into everyday development workflows. This is not a hand-off or sign-off testing function and not a UI-only or Selenium-heavy automation position. Why this role matters: This department powers the financial workflows that keep veterinary practices running smoothly. When payments are reliable, clinics can focus on patient care and not system issues. This role ensures that every change we ship is safe, stable, and trustworthy before it reaches a live clinic.

Requirements

Strong TypeScript experience (core language for services, tooling, and tests)
Deep experience with Jest or equivalent modern test frameworks
Proven ability to design and maintain test frameworks and automation infrastructure
Experience testing RESTful APIs and event‑driven systems
Working knowledge of AWS‑based architectures (e.g., Lambda, API Gateway, DynamoDB, messaging)
Experience integrating automated tests into CI/CD pipelines

Responsibilities

Design and evolve automated API and component‑level test frameworks in TypeScript, aligned with modern testing best practices.
Build tests that validate running services and real infrastructure behavior, rather than heavily mocked code paths.
Establish and maintain integration and contract testing for service‑to‑service and external interfaces.
Strengthen automated regression coverage to support reliable, frequent releases.
Expand and curate a focused Playwright E2E suite that protects critical user and payment workflows.
Enable local and CI‑based test execution using containerized or ephemeral infrastructure where appropriate.
Partner with engineers to integrate testing into normal development and deployment workflows.
Leverage observability and production telemetry signals to inform test coverage and failure‑detection strategies.
