C. Mack Solutions is seeking a Junior AI Developer to join an agile AI development team supporting a mission-critical program for the Federal Government. Working under the guidance of senior developers and architects, you will help build, test, and integrate AI-enabled applications — including Generative AI and agentic solutions built on Google Gemini — and grow your skills on a team that values mentorship, rapid iteration, and working software.

Responsibilities:

• Develop, test, and maintain software components for AI/ML pilot projects and use cases, including Google Gemini-based applications, AI agents, and tool/MCP integrations, under the direction of senior team members.
• Build and consume RESTful APIs and back-end services (e.g., Python with FastAPI or Flask) that connect applications to commercial or open-source AI models and enterprise data sources.
• Write and refine prompts, and help evaluate model outputs for accuracy, reliability, and consistency.
• Write unit tests and perform API testing (e.g., Postman) to validate request/response behavior, authentication flows, and error handling before release.
• Work with SQL and NoSQL data stores and cloud data services (e.g., Google BigQuery) to query, prepare, and serve data to AI-enabled applications.
• Support deployment of applications to cloud environments (Google Cloud and AWS) and through CI/CD pipelines.
• Use AI-assisted development tools responsibly to accelerate coding, testing, and documentation, in line with program policies.
• Collaborate with developers, testers, and Data Scientist teams on prototyping teams that deliver working software on short timelines.
• Actively participate in agile delivery ceremonies, including sprint planning, daily stand-ups, sprint testing, demonstrations, and retrospectives.
• Author clear technical documentation, including design notes, API documentation, and handoff/transition materials.
• Stay current with advancements in AI technologies, tools, and best practices, and share what you learn with the team.

• Programming proficiency in Python plus at least one additional language such as Java, JavaScript, or TypeScript.
• Hands-on experience building or consuming RESTful APIs, including familiarity with authentication methods, data formats (JSON/YAML), and API error handling.
• Familiarity with fundamental Generative AI concepts, including Large Language Models (LLMs), prompt engineering, and agentic AI patterns.
• Exposure to building an application that integrates a commercial or open-source AI model API (academic, internship, or project experience acceptable).
• Working knowledge of SQL and exposure to at least one cloud platform (Google Cloud or AWS).
• Experience with Git-based version control, unit testing, and object-oriented programming.
