The Role


We’re looking for a Principal Applied AI Engineer to shape and build AI systems that make a tangible impact.

You’ll work closely with clients and cross-functional teams to design and deliver scalable, production-ready AI capabilities — from intelligent automation to generative applications.

• Design, build and deploy applied AI systems that integrate seamlessly with existing software and data platforms.
• Develop and maintain backend systems, APIs, and frontends in alignment with software engineering best practices.
• Mentor and develop engineers (both within Colibri and client teams), building capability and confidence.
• Define and uphold best practices in AI engineering, including robust architecture, testing, and deployment.
• Partner with data scientists, product managers, and delivery leads to ensure AI solutions are practical, ethical, and aligned with business outcomes.
• Contribute to Colibri’s internal capability development; shaping frameworks, patterns, building reusable code repositories or other assets and thought leadership in applied AI.
• Represent Colibri as a trusted technical advisor, communicating complex AI concepts clearly to non-technical audiences.

• Experience mentoring engineers and guiding clients through AI adoption and delivery.
• Excellent communication and stakeholder management skills, able to lead with empathy and clarity in complex client environments
