Job summary

Credence in the United States is seeking a Senior AI Software Engineer to design, develop, and deploy advanced AI-driven solutions for federal clients, including generative AI and agentic systems. You will collaborate with cross-functional teams to deliver secure, scalable, mission-focused capabilities and mentor engineers.

The role emphasizes technical leadership, rigorous software practices, and responsible AI development to deliver measurable mission impact.

Qualifications

• 7+ years of hands-on software engineering experience delivering AI/ML or LLM-powered solutions in production or prod-like environments.
• Experience building generative AI applications, working with LLMs, implementing tool/function calling, and applying model evaluation, prompt/context engineering, or retrieval-augmented generation approaches.
• Experience designing or implementing agentic AI solutions using frameworks or platforms such as Agent2Agent Protocol, Bedrock Agents, Mastra, CrewAI, Strands, AgentCore, LangChain, or LangGraph.
• Strong understanding of leading AI APIs and model platforms such as OpenAI, Anthropic, Gemini, Amazon Bedrock, and Google Vertex AI.
• Proficiency in TypeScript and familiarity with libraries/frameworks such as Nx, Next.js, Mastra, Vercel AI SDK, Playwright, Jest, and Vite.
• Python proficiency and familiarity with libraries and frameworks (uv, Pydantic, FastAPI, CrewAI, LangChain, LangGraph, Unstructured).
• Demonstrated curiosity and practical experimentation with emerging AI technologies, with a strong focus on responsible innovation and measurable mission impact.
• Familiarity with CI/CD pipelines (GitLab CI).
• Experience with VS Code and AI extensions such as Claude Code.

Responsibilities

• Generative AI & LLM Solution Delivery: Lead design, development, prototyping, and refinement of AI-powered capabilities using generative AI, large language models, retrieval patterns, prompt/context engineering, and secure API integrations.
• Agentic AI System Development: Own end-to-end agentic AI development lifecycles, including model selection, agent design, tool/function calling, orchestration, response synthesis, evaluation, and deployment of reliable AI agents.
• Senior Software Engineering Leadership: Apply strong software engineering principles to design maintainable, testable, and scalable systems; conduct code reviews, establish technical patterns, and leverage AI-assisted development tools responsibly to accelerate delivery.
• Cross-Functional Technical Collaboration: Partner with data engineers, software engineers, data scientists, cloud engineers, and mission stakeholders to translate business and mission needs into operational AI and automation solutions.
• Cloud Enablement & DevSecOps Integration: Design and automate deployment workflows using Infrastructure as Code (IaC), CI/CD pipelines, containers, and cloud-native services to support secure, repeatable, and scalable AI delivery.
• Production Monitoring & Optimization: Monitor AI systems post-deployment, perform performance tuning, and apply best practices for reliability and scalability.
• Technical Rigor & Documentation: Write clean, well-documented code following industry and federal guidelines; support reproducible development.
• Technical Mentorship & Continuous Improvement: Stay current on emerging AI/ML trends, agentic frameworks, model capabilities, and engineering practices while mentoring team members and contributing to reusable standards, documentation, and technical design reviews.
