Senior Software Engineer — Quality, Test & CI Engineering

Role Description

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
• Establishing practices that 60+ engineers can adopt and benefit from every day

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.

Qualifications

• 7–12 years of experience in software engineering, with a strong and deliberate focus on quality engineering and CI/CD.
• Deep expertise in test strategy and architecture.
• Hands-on experience building and maintaining CI/CD pipelines at scale.
• Comfortable across a polyglot stack: TypeScript/React, Node.js or Java, Python.
• Experience with modern test tooling: Playwright, Vitest, Jest, Cypress, or equivalents.
• Strong understanding of software quality metrics.
• Excellent written communication skills.
• Comfortable working in a remote-first, async culture.
• Autonomy and ownership mindset.
• Bonus: experience with performance/load testing tools; hands-on use of AI-assisted test generation tools; open-source contributions; experience rolling out quality standards across large engineering teams; cybersecurity domain knowledge.

Requirements

• Audit the current state of test coverage and CI pipelines across the OpenCTI, OpenAEV, and OpenGRC.
• Define and implement a cross-product test strategy covering unit, integration, end-to-end, and contract testing.
• Lead the consolidation and standardisation of CI/CD pipelines towards GitHub Actions.
• Build shared test tooling, templates, and libraries for product teams.
• Introduce and maintain performance and load testing practices.
• Define and enforce standards for test reliability and pipeline speed.
• Work closely with product engineering teams to embed quality practices.
• Stay current with the testing, CI/CD, and AI-assisted engineering landscape.

Benefits

• Competitive pay + equity - everyone shares in our success.
• Remote-first, flexible, and balanced - work that fits your life.
• Your setup, your choice - pick the gear that works for you.
• Twice-a-year gatherings - we meet in person for regional and global offsites.
