Role: Agentic AI Engineer  for Secure Software Engineering (Mid-level)

🤖🔐 We’re building agentic AI for secure software delivery - join our team in Engineering & Digital Transformation to develop agents that make SSDLC security faster, smarter, and easier to operate.

In Thales Engineering & Digital Transformation, we build and evolve engineering tools and practices that accelerate secure software delivery across the lifecycle.

We’re strengthening our team with a Mid-Level Agentic Developer to design and deliver LLM-powered agents  that improve Thales’ Secure Software Development Life Cycle (SSDLC).

Your focus:

• Making cybersecurity activities faster, smarter, and more scalable starting with vulnerability detection and remediation  and supporting the team in building real engineering value from agentic AI

What you’ll do:

• First priority: vulnerability detection and remediation
• Design and develop agentic AI tools to automate cybersecurity workflows inside SSDLC
• Build and iterate on multiple agents that help teams execute secure development activities more efficiently.
• Prototype, experiment, and assess new approaches through technical implementation and evaluation (including vendor/open-source solutions).
• Contribute to SSDLC tooling improvement by integrating your solutions with existing practices and platforms.
• Collaborate in Agile ceremonies (backlog refinement, DoR/DoD validation, sprint reviews) and propose well-scoped work items

Support team members by sharing knowledge and best practices on:

• LLM technologies
• Agentic patterns
• Cloud-based delivery approaches
• Stay on top of the technology landscape (AI for cybersecurity) and recommend tools/tactics based on evidence

How you’ll work with us:

• You’ll join a team responsible for engineering tooled practices and digital/AI transformation, where curiosity, hands-on experimentation, and strong collaboration are key
• You’ll help turn innovative AI concepts into usable, reliable security tooling for real development teams.

Requirements:

• Strong knowledge of LLMs and agentic systems
• Good understanding of SSDLC steps and existing security tooling
• Cloud experience: Azure and GCP
• Experience building with LLMs accessible through an AI gateway (models v1 API), a cloud-premise agentic platform (being set up)
• Ability to experiment with technologies and communicate outcomes clearly in fluent technical English (writing + speaking)

Nice to have:

• MLOps experience
• AI certification(s)

Soft skills:

• Teamwork, problem solving, time management 
• Attention to detail 
• Strong communication and willingness to help others
