We're looking for a forward-thinking
Automation Engineer
to help us build a fully modern,
AI-driven
test automation pipeline for our next-generation platform. You'll help define how we test everything - from core product functionalities to the behavior of the
LLMs and agentic workflows
.

In this role you’ll combine
Salesforce

If you are passionate about rethinking traditional testing paradigms and building smart infrastructure, we want you on our team!

Responsibilities:

  • Help design and scale automation strategy: Frameworks, tooling, standards, and processes.
  • AI tooling & infrastructure: Design evaluation systems for LLM-powered features and bring AI capabilities into the framework - QA agents, natural-language-to-test tools, LLM-assisted failure triage, etc.
  • Salesforce automation: Build and scale automated test coverage for complex Salesforce multi-cloud deployments - Lightning Web Components, custom Apex triggers, and managed packages - and solve the automation challenges that come with them.
  • FE coverage: Write automated tests across the stack, from backend APIs and AI agents to React frontends.

Requirements:

  • 4+ years of experience in test automation infrastructure.
  • Experience testing or evaluating LLM-powered applications, agentic workflows, or non-deterministic AI outputs.
  • AI tooling competency - demonstrated experience or deep conceptual familiarity with AI coding tools (Cursor, Claude Code, GitHub Copilot) or dedicated AI testing environments, used to generate, optimize, and maintain test infrastructure.
  • Excellent communication skills in English, self-motivated and well organized.
  • Solid hands-on understanding of Salesforce architecture, including Salesforce-specific automation challenges (shadow DOM, nested iframes, sandbox environments).
  • Proficiency in at least one modern language: TypeScript/JavaScript, Python, or Java.
  • Modern frameworks - Experience with Playwright (preferred), Selenium, or Cypress.
  • API and integration testing - testing REST/SOAP APIs and SOQL queries using Postman, Playwright API, or custom code-based wrappers, plus validating third-party integrations.
  • Ownership mindset - you take full responsibility for quality and drive initiatives from idea to production.
  • B.Sc. in Computer Science or equivalent practical experience.

What we're looking for?
We're looking for a Senior Front-End Developer who cares deeply about performance, architecture, and code quality — and who uses agentic AI workflows to work faster and at higher leverage.

This role goes beyond typical feature work. You'll drive continuous refactoring, performance tuning, and architectural improvements across the entire project — and you won't be limited to the front-end. You'll build and refine the agentic workflows you use to do it, treating your own tooling as part of the job.

The Senior Front-End Developer will be engaged with the company as a contractor (Private Entrepreneur).

What You'll Do:

  • Drive performance, refactoring, and architecture improvements across the project, not just the UI layer
  • Design and evolve agentic workflows to accelerate refactoring, testing, and day-to-day development
  • Optimize application performance against Web Vitals and other real-user metrics
  • Contribute architecture and UX ideas in product design and planning discussions
  • Write scalable, reusable code in TypeScript and Tailwind CSS

Requirements:

  • 5+ years of front-end experience building complex, high-load applications
  • 4+ years of hands-on React
  • Strong TypeScript proficiency
  • Experience with Tailwind CSS and TanStack Query (React Query)
  • Solid grasp of browser internals — JS engines, DOM APIs, event handling — and hands-on performance profiling/optimization
  • Deep understanding of mobile-first responsive design and cross-browser compatibility
  • Experience using agentic AI coding tools (e.g. Claude Code, Cursor, Copilot) in real projects
  • Ability to break down complex, ambiguous requirements into actionable tasks
  • Strong sense of ownership and an impact-driven, outcome-focused mindset
  • Comfortable with Git and Agile ways of working
  • Upper-Intermediate English or higher

Nice to have

  • Experience authoring or customizing AI/agent tooling — MCP servers, custom agents, prompt/workflow design
  • Background in build tooling and bundle optimization (Vite, Webpack)
  • Experience with observability / RUM (Sentry, Datadog, SpeedCurve, etc.)
  • Contributions to a design system or shared component library
  • Backend or full-stack experience
