Job description

Want to shape how AI is transforming software delivery in enterprise environments? At Mimacom, we're looking for a Senior AI Engineer who combines strong software engineering expertise with hands‑on experience building and operating AI solutions in production.

This role goes far beyond coding assistants and AI experimentation. You'll design, build, and scale agentic systems that create measurable business impact while meeting enterprise requirements for security, governance, and reliability.

What You'll Do

• Build and deliver production-grade AI and agentic solutions for enterprise clients.
• Design end-to-end architectures combining LLMs, RAG, agents, workflows, and enterprise integrations.
• Develop scalable applications using Java, Spring Boot, TypeScript, Node.js, and Python.
• Integrate AI capabilities into business processes, platforms, APIs, and event-driven architectures.
• Create and optimize RAG pipelines, multi-agent systems, and context-engineering strategies.
• Establish AI best practices around observability, evaluation, security, governance, and cost management.
• Enable teams through reusable agent workflows, MCP integrations, custom tools, and AI-assisted development practices.

What You'll Bring

• 5+ years of software engineering experience and 2+ years building LLM-based solutions in production.
• Strong expertise with Java/Spring Boot, TypeScript/Node.js, and Python.
• Experience designing cloud-native solutions on Azure and/or AWS.
• Hands-on knowledge of Azure OpenAI, AI Search, AI Foundry, or similar AI platforms.
• Experience with RAG, agent orchestration, prompt and context engineering, and LLMOps.
• Excellent understanding of testing, CI/CD, observability, security, and enterprise architecture.
• Strong communication skills and the ability to translate AI capabilities into business value.

Nice to Have

• Terraform or AWS CDK.
• LangGraph, Semantic Kernel, Claude Agent SDK, Bedrock Agents, or similar frameworks.
• Document intelligence and OCR solutions.

What Makes a Strong Fit?

You've successfully delivered AI solutions to real users, can explain the architecture decisions behind them, and understand how to operate them securely and reliably in production.

This role is not focused on AI experimentation or simple chatbot usage. We are looking for someone who has built, shipped, and owned AI-powered systems that create measurable outcomes.

What to Expect

Your personal and professional growth is important to us, and we offer a range of benefits and opportunities to support your journey:

Work-Life Balance That Actually Works

• 30 days of paid vacation to recharge and unwind.
• Flexible working hours to fit your lifestyle and personal commitments.
• A culture that respects your time and promotes sustainable work habits.
• A personalized development plan aligned with your goals and ambitions.
• Opportunities to learn new technologies.
• Access to challenging, high-impact projects that accelerate your professional growth.
• Choose the equipment that works best for you — macOS or Windows.
• Work with modern tools, technologies, and well-structured engineering practices.
• Collaborative, supportive, and international environment.
• Regular team events, meetups, and retreats to connect beyond day-to-day work.
• A culture built on trust, ownership, and shared success.

Meaningful Work at Scale

• Build products used by millions of users daily.
• Contribute to innovative solutions in industries like automotive, retail, and banking.
• See the real-world impact of your work.

At Mimacom, we believe that diversity drives innovation and better outcomes. We are committed to creating an inclusive workplace where everyone feels valued, respected, and empowered to contribute their unique perspectives. We welcome applications from candidates of all backgrounds and experiences and are dedicated to providing equal opportunities for all.
