This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Principal Software Developer (AI / Agentic Systems) in Canada.

This role offers the opportunity to shape the next generation of AI-driven customer service technologies in a highly innovative, fast-moving environment. You will design and build advanced agentic systems that combine LLMs, automation, and real-world tool interaction to power intelligent workflows used by global brands. Working at the intersection of AI, software engineering, and product innovation, you will help define how autonomous and semi-autonomous agents operate in production environments. The role blends hands-on architecture with strategic technical leadership, requiring both deep engineering expertise and creative problem-solving. You will collaborate closely with cross-functional teams to translate complex business needs into scalable AI-powered solutions. This is a highly impactful position where your work directly influences real customer experiences at scale.

In this role, you will architect, build, and evolve advanced AI-powered systems while guiding engineering teams toward high-quality, scalable solutions:

• Design and develop AI-driven software systems using .NET, Node.js, Python, and modern AI frameworks, with a focus on agentic and LLM-based architectures
• Build and optimize autonomous and semi-autonomous AI agents capable of reasoning, planning, and interacting with APIs, tools, and browser environments
• Lead technical problem-solving efforts for complex engineering challenges, driving innovation and efficiency across systems
• Mentor and support engineers, fostering technical growth and promoting engineering best practices across the team
• Collaborate with product managers, designers, and stakeholders to translate requirements into robust, scalable technical designs
• Ensure code quality, testing standards, system reliability, and long-term maintainability across production systems
• Stay current with emerging AI technologies and integrate new approaches to continuously improve platform capabilities

Requirements

Candidates should bring deep software engineering expertise combined with strong AI system design experience and a passion for innovation:

• 7+ years of software development experience with strong proficiency in .NET, Node.js, and Python
• Proven experience building or contributing to generative AI systems, including LLM-based applications and frameworks
• Hands-on experience designing agentic or autonomous systems that interact with real-world environments
• Strong understanding of AI safety, guardrails, and human-in-the-loop design principles
• Experience with LLM optimization, inference pipelines, or fine-tuning for agent-based use cases
• Solid background in distributed systems, microservices, and cloud platforms (AWS, Azure, or GCP)
• Strong communication skills with the ability to explain complex technical concepts clearly across teams
• Demonstrated leadership or mentorship experience in fast-paced engineering environments
• Familiarity with CI/CD, DevOps practices, and modern software delivery workflows
• Bonus: experience with frontend frameworks (React, Angular, or Vue.js), open-source contributions, or startup environments

Benefits

• Competitive compensation aligned with experience and expertise
• Flexible remote-first work environment within Canada
• Opportunity to work on cutting-edge AI and agentic systems at scale
• Collaborative, innovation-driven engineering culture
• Exposure to advanced LLM technologies and real-world production AI use cases
• Professional growth through mentorship, learning, and technical ownership
• Inclusive and supportive work environment focused on experimentation and creativity
• Opportunity to shape the future of AI-powered customer experience platforms
