Role: Python AI Agent Engineer (Mid-level)

About the Mission:

Join us in building the future of AI-enhanced engineering. We're creating a revolutionary agent garden from the ground up—a programmatic system that will enable 40,000+ engineers to seamlessly work with AI agents, tools, and data.

As an Agent Garden Developer, you'll work on the core infrastructure that powers this system: building agents, creating connectors, implementing orchestration logic, and enabling the marketplace where engineers discover and contribute to AI services.

This is a unique opportunity to work at the cutting edge of AI and software engineering, learn from experienced tech leads, and contribute to a system that will have massive real-world impact.

What We Offer:

• Mentorship program: Learn from experienced tech leads and principal engineers

• Growth opportunities: Clear development path with support for advancing your skills

• Agile, autonomous teams with management-free delivery, clear roles, and predictability focus

• Modern tech stack: Work with latest AI/ML technologies, frameworks, and tools

Why This Role is Exciting:

• Work with Cutting-Edge AI: get hands-on experience building agentic AI systems

• Learn from Experts: work alongside tech leads and principal engineers who will mentor you

• Massive Impact: your code will power a system used by 40,000+ engineers

• Greenfield Project: build new infrastructure with modern technologies while connecting to existing systems

• Career Growth:  clear path to senior roles with mentorship, challenging projects, opportunities to lead

What You'll Do:

Build Agent Infrastructure:

• Develop agents, MCP (Model Context Protocol) connectors and more

• Build frameworks making it easy for others to create and deploy agents

• Contribute to the programmatic (code-first) system architecture

Integrate AI with Engineering Tools:

• Work with AI/ML APIs (OpenAI, Anthropic, or similar) to build intelligent features

• Implement prompt engineering patterns and interaction flows

• Connect AI capabilities with engineering tools (e.g., GitLab, Polarion, data sources)

• Build authentication and authorization for secure multi-system integration

Write High-Quality Code:

• Follow software craftsmanship principles: TDD, clean code, living documentation

• Write unit and integration tests for your components

• Participate in code reviews and learn from senior engineers

• Document your work to help others build upon it

Grow Your Skills:

• Work closely with tech leads and principal engineers who will mentor you

• Learn emerging technologies: agentic AI, prompt engineering, MCP

• Take increasing ownership of features and components

• Share your learnings with the team and contribute to knowledge base

About you:

Your Experience:

• Backend development: Python, Kotlin, Node.js, or similar languages

• API integration: Worked with RESTful APIs, understand authentication fundamentals

• Problem-solving: Can break down complex problems and implement solutions

• Collaboration: Worked in team environments using Git and code reviews

Your Technical Skills:

• Programming: Python or other backend languages (Java, Node.js, Kotlin)

• APIs: RESTful design, HTTP, JSON, authentication (OAuth, JWT)

• Data handling: Databases (SQL or NoSQL), data processing

• Testing: Unit testing, basic integration testing

• Tools: Git, basic CI/CD, command-line proficiency

• Cloud services: Experience with AWS, Azure, or Google Cloud

Your Approach:

• Quality-conscious: Care about writing code that works reliably

• Test-aware: Understand value of automated testing and TDD/BDD practices (even if still building these skills)

• Eager to learn craftsmanship: Excited to grow your software craftsmanship practices

At Thales, we’re committed to fostering a workplace where respect, trust, collaboration, and passion drive everything we do. Here, you’ll feel empowered to bring your best self, thrive in a supportive culture, and love the work you do. Join us, and be part of a team reimagining technology to create solutions that truly make a difference – for a safer, greener, and more inclusive world.
