SaaS Platform · React + Fastify · PostgreSQL

About the Project

We’re building a sophisticated AI-powered matching and analytics platform that uses multi-dimensional profiling and advanced algorithms to optimize decision-making.

The product has a validated prototype and real traction. We’re now moving into production hardening and scale, and we’re looking for a senior developer to take ownership of the backend architecture while actively evolving the frontend.

A core part of this role is working AI-first: we expect you to use Claude Code as a primary development tool, not as an experiment or side-assist.

The Role

You’ll design and implement the full production backend for our React-based SaaS platform, replacing mock data with real infrastructure:

• databases
• authentication
• APIs
• AI integrations
• deployment pipelines

You’ll also contribute directly to the frontend where needed.

Claude Code is a hard requirement.

We expect you to be comfortable (or explicitly motivated) to:

• scaffold systems with AI
• refactor and evolve large codebases using AI assistance
• co-design architecture with Claude
• use AI for documentation, tests, migrations, and reasoning

This is an AI-augmented engineering role, not a traditional “write everything by hand” position.

We're looking for a Senior Engineer to join our product team. You'll work primarily on frontend development with a focus on React and Gutenberg, while contributing across the stack as needed.

You'll report to the Tech Lead. We're looking for someone who, once onboarded, can own their delivery end-to-end without needing close oversight.

What you'll do

• Deliver large or complex features on time, in line with the local architecture
• Write and maintain tests to support confident, frequent releases
• Spot opportunities for refactoring and improvements to keep the codebase healthy
• Help teammates get unstuck — give advice when asked and provide thoughtful code reviews

What we're looking for

Technical skills:

• Strong experience with React and Gutenberg block development
• Svelte experience (highly valued)
• Solid understanding of modern JavaScript/TypeScript
• Experience writing and maintaining tests (unit, integration, e2e)
• Familiarity with testing tools such as Vitest, Playwright, or similar
• Frontend-focused, but comfortable working with PHP and WordPress backend code when needed
• Working knowledge of web security fundamentals (e.g. XSS, CSRF, input validation)
• Understanding of CI/CD pipelines and automated testing workflows

You should be someone who:

• Writes code that's easy to test, easy to read, and handles edge cases gracefully
• Treats tests as a tool for speed and confidence, not a checkbox
• Cares about code quality, maintainability, and security
• Breaks work into small, deliverable chunks that support continuous integration
• Communicates proactively and clearly — surfaces risks early and explains trade-offs
• Enjoys working in a team
• Is comfortable navigating ambiguity and making pragmatic tradeoffs

How we work

We ship in small batches, release frequently, and course-correct quickly. When something breaks, we fix it fast. 

We value working software over lengthy planning cycles, and we write tests to move faster, not slower. If you prefer big upfront designs and long release windows, this probably isn't the right fit.

Fully remote, mostly async. Europe-based team (Rome timezone) — we're looking for someone with significant overlap.

- Expert-level understanding of DOM manipulation and scraping of asynchronous, "heavy" web apps. Knowledge of browser performance profiling to ensure the extension doesn't slow down the user's browser. Understanding of how to secure sensitive data within local extension storage.

- Proven experience contributing to mature Chrome extension projects maintained by multiple R&D teams, with complex shared codebases.

- Experience developing or maintaining automation and performance testing tools to monitor extension impact at scale, detect regressions, and ensure minimal disruption to end users.

Job Responsibilities

Our Chrome/Edge extension is a core part of the clinician's daily workflow. It lives alongside Electronic Health Record (EHR) systems, capturing data and providing real-time AI suggestions. We need a high-level specialist to lead the development of this extension, ensuring it remains robust against external site changes and maintains strict medical-grade security. Part of your responsibilities will include, but not limited to:

- Lead the architecture and development of our browser extensions using Manifest V3.

- Build sophisticated content scripts that reliably scrape and interact with dynamic EHR platforms.

- Manage complex background logic using Service Workers for session lifecycle management.

- Ensure the extension’s React-based UI (popups and overlays) is high-performance and non-intrusive.

- Implement secure, cross-context messaging between content scripts, service workers, and the main web app.

- Develop robust "DOM observers" to handle updates on third-party sites without breaking functionality.

- Collaborate effectively with multiple R&D teams on large, mature extension projects, contributing to a shared, scalable codebase.

- Design, implement, and maintain automation frameworks to continuously monitor extension performance, detect regressions, and measure the impact on browsers and external systems.

- Establish best practices for performance, security, and maintainability in large-scale, multi-team extension projects.

Department/Project Description
