Senior Software Engineer — Quality, Test & CI Engineering (XTM Foundation)

About this role

## The Company

Filigran, founded in October 2022, stands out in the cybertech ecosystem for its commitment to revolutionizing cyber threat management with a proactive approach. Its mission is to develop innovative open-source solutions designed to anticipate cyber threats, identify security gaps, and strengthen organizational security posture.

Filigran solutions are now trusted by over 6,000 public and private organizations worldwide.

## The Role

We're looking for a Senior Software Engineer with deep expertise in software quality, testing, and continuous integration to join the XTM Foundation team — Filigran's cross-product engineering team responsible for architecture, quality, shared tooling, and technical standards across the XTM Suite (OpenCTI, OpenAEV, OpenGRC).

You will own the quality and CI engineering mission across all three products: raising test coverage, building robust and reliable pipelines, and establishing practices that 60+ engineers can adopt and benefit from every day. This is not a QA role — it's a senior engineering role where quality and CI are first-class engineering concerns, not afterthoughts.

This is a high-impact, hands-on role. You'll audit what exists, identify the highest-leverage improvements, build the tooling and standards, and work directly with product teams to roll them out. You'll be the person who makes quality a competitive advantage for Filigran's engineering culture.

## Your Responsibilities

• Audit the current state of test coverage and CI pipelines across the OpenCTI, OpenAEV, and OpenGRC — identify critical gaps and define a prioritised roadmap to address them.
• Define and implement a cross-product test strategy covering unit, integration, end-to-end, and contract testing — adapted to each layer of the stack (GraphQL API, TypeScript/React frontend, Node.js/Java backend, Python connectors).
• Lead the consolidation and standardisation of CI/CD pipelines towards GitHub Actions, introducing quality gates...
