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
