This is the job

We are looking for a Senior AI Engineer to join a Tech Solutions team responsible for building reusable technology components and solutions, defining architectures, and promoting engineering best practice across development teams.

You will be the first AI Enablement specialist within the team, playing a key role in defining the strategy, capabilities, and engineering standards required to integrate Artificial Intelligence into the organization's development ecosystem.

This role combines hands‑on software engineering with architectural ownership and technology exploration. You will research emerging AI technologies and transform them into production-ready, secure, observable, scalable, and easy-to-adopt solutions that can be reused across multiple products and engineering teams.

This is you

• Senior-level experience in backend software development.
• Strong expertise in Node.js and solid experience with JavaScript and/or TypeScript.
• Hands‑on experience with AWS, serverless architectures, and distributed systems.
• Experience designing and developing APIs, libraries, frameworks, plugins, or other reusable software components.
• Strong understanding of software design principles and engineering best practices, including testing, security, observability, and CI/CD.
• Experience contributing to software architecture, technical design, and engineering decision‑making.
• Hands‑on experience developing or integrating solutions based on Large Language Models (LLMs) and Generative AI.
• Ability to translate specific business and technical requirements into generic, scalable, and reusable solutions.
• Ability to research emerging technologies, evaluate alternatives, and transform concepts and proof‑of‑concepts into production‑ready solutions.
• Self‑driven mindset with a high degree of ownership and autonomy.
• Strong communication, technical documentation, and cross‑team collaboration skills.

Nice‑to‑have skills

• Experience with Amazon Bedrock or other Generative AI platforms.
• Experience with the Serverless Framework and plugin development.
• Hands‑on knowledge of RAG, AI agents, tool calling, Model Context Protocol (MCP), structured generation, embeddings, and semantic search.
• Experience with AWS services such as Lambda, API Gateway, Step Functions, EventBridge, SQS, SNS, and DynamoDB.
• Knowledge of vector databases and semantic search technologies.
• Experience implementing evaluation frameworks, guardrails, observability, and operational practices for LLM-based applications.
• Experience building internal development platforms, frameworks, or developer tools.

This is your role

• Design and develop reusable components, libraries, APIs, plugins, and tools that enable AI adoption across products and engineering teams.
• Integrate AI capabilities into the organization's internal development framework and make them easy for other engineering teams to adopt.
• Define reference architectures, technical patterns, standards, and best practices for Generative AI‑based solutions.
• Design and implement integrations with Large Language Models and AI services, primarily within the AWS ecosystem.
