Filigran - Senior Software Engineer — AI-Native Engineering (XTM Foundation)

• Define and own Filigran's AI-Native engineering strategy: which tools, which workflows, which practices, and how they evolve as the landscape moves fast. • Run structured experiments to evaluate new AI coding tools and agents (Cursor, GitHub Copilot, Cline, MCP servers, code generation agents…), measure their real impact on velocity and quality, and translate findings into actionable recommendations. • Build the guardrails and engineering standards that ensure AI-generated code is maintainable, tested, and consistent with our quality bar — not just fast to produce. • Work directly with product engineering teams (~80 engineers) to embed AI practices into their day-to-day workflows: pair programming with AI, AI-assisted code review, test generation, documentation, and beyond. • Stay permanently ahead of the curve — the AI tooling landscape moves weekly. You'll be the one tracking it, filtering the noise, and surfacing what actually matters for a team like ours. • Work in the XTM Foundation team to turn AI practices into shared building blocks for every product team: agent workflows in our CI pipelines (dependency updates, flaky test triage, review assistance), shared MCP servers and prompt libraries, versioned AI configuration in the repositories, and written rules on tools and data handling that apply to everyone. • Contribute to Filigran's external voice on AI-Native engineering — blog posts, open-source contributions, conference talks — as the opportunity arises. • 🤝 Who You'll Work With • Reports to: Principal Engineer of XTM Foundation team. • Key collaborators: Engineers and Engineering Managers across OpenCTI, OpenAEV, and OpenGRC product teams; VP of Technology; CTO. • Working model: You will split your time between XTM Foundation team work (research, experimentation, standards) and direct collaboration with product teams to embed AI practices in real engineering workflows. • 🧬 Profile We're Looking For • 7+ years of software engineering experience — you are a strong engineer first. You understand what good code looks like, and that's what makes your judgment on AI credible. • You are genuinely AI-first in how you work. Not as a trend, not as a productivity hack. You've already transformed how you build software, you can show what you built and what you measured, and you want to help others do the same. • Proven experience deploying AI-assisted development practices within an engineering team: you've done this before, you know what resistance looks like, and you know what actually works and what doesn't. • Deep, hands-on familiarity with the current AI coding tooling landscape: agentic coding tools, LLM-powered code review, prompt engineering for development workflows, MCP ecosystems, and what's coming next. • Strong full-stack engineering background — you can evaluate AI output across the whole stack and contribute code yourself when it matters. • You can make a clear case, with evidence. You're a natural communicator who can discuss a trade-off with a skeptical senior engineer just as well as you can help a junior developer get started. • Comfortable working in a remote-first, async culture with teams across multiple time zones; clear communicator in English. • Autonomy and ownership mindset: you drive this agenda without waiting for direction, and you bring others with you rather than working alone. • Bonus: experience with open-source communities, cybersecurity domain knowledge, contributions to AI tooling projects, or public writing/speaking on AI-Native engineering. • 🌱 Why Join Filigran?
