## About the Role

5+ years of professional experience in software engineering, backend, or platform engineering roles
Strong software engineering background with hands?on experience in modern architectures
Experience in the insurance domain, with exposure to insurance platforms, business processes, or core systems (e.g. policies, claims, billing, underwriting, integrations)
Familiarity with AI?native engineering practices, such as agent?based or orchestration?driven approaches (e.g. Gastown?style concepts)
Hands?on experience with Claude or similar large language models, including:
Using AI tools directly within an IDE or development workflow
Writing effective prompts for code analysis, code generation, and iterative refinement
Solid understanding of modern engineering patterns, including:
API design and integration
Microservices architectures
Event?driven and integration?based systems
Experience working with existing, non?trivial codebases and enabling AI?driven analysis on top of them
Practical understanding of prompt engineering as an engineering tool, not just experimentation
A mindset focused on production quality, repeatability, and maintainability rather than demos
Very good command of English (spoken and written), suitable for working in an international, client?facing environment

## Description

Who We AreWe are moving towards an AI?native delivery model where small, highly skilled teams are augmented by AI agents. Instead of relying on traditional, fully manual analysis and specification phases, we use AI to accelerate understanding of existing systems, identify gaps, and generate high?quality specifications.As an AI Engineer, you play a key role in building and running the technical backbone that enables this new way of working.What You'll Be DoingImplement and maintain the AI backbone that supports end?to?end deliveryConfigure, train, and orchestrate AI models and agents working directly on existing codebasesEnable automated gap analysis, requirement refinement, and specification generation using AIIntegrate AI capabilities into real?world software systems, not isolated PoCsEnsure AI?driven outputs are robust, scalable, and accurate enough for enterprise useContinuously improve prompts, workflows, and agent coordination to increase quality and consistencyWork closely with the Intent Engineer to iterate on outputs and ensure alignment with business intentSupport a shift from traditional requirement creation to AI?assisted, exploration?driven deliveryWhat You'll Bring Along5+ years of professional experience in software engineering, backend, or platform engineering rolesStrong software engineering background with hands?on experience in modern architecturesExperience in the insurance domain, with exposure to insurance platforms, business processes, or core systems (e.g. policies, claims, billing, underwriting, integrations)Familiarity with AI?native engineering practices, such as agent?based or orchestration?driven approaches (e.g. Gastown?style concepts)Hands?on experience with Claude or similar large language models, including:Using AI tools directly within an IDE or development workflowWriting effective prompts for code analysis, code generation, and iterative refinementSolid understanding of modern engineering patterns, including:API design and integrationMicroservices architecturesEvent?driven and integration?based systemsExperience working with existing, non?trivial codebases and enabling AI?driven analysis on top of themPractical understanding of prompt engineering as an engineering tool, not just experimentationA mindset focused on production quality, repeatability, and maintainability rather than demosVery good command of English (spoken and written), suitable for working in an international, client?facing environment#J-*****-Ljbffr
