MQ, Entity Framework Core, Angular

As our Principal Engineer, you will, together with our architects, define and drive the technical direction of our product uHabi. You’ll take ownership of the architectural vision, ensuring scalability, maintainability, and long-term technical health. As part of our journey toward AI-first engineering, you will help shape how AI is applied across development, testing, and operations, with clear guardrails for quality, security, and responsible use.

While you work closely with development teams, you operate outside the Scrum teams — setting the guardrails, not running the sprints. You remain technically hands‑on through targeted coding, prototyping, and technical deep‑dives where it creates the most value.
You connect long‑term technical strategy with day‑to‑day implementation, giving teams clarity, consistency, and confidence in the platform’s evolution. You will not have people management responsibility, but your impact will be felt across everything they build.

• Define the overarching system architecture and guide its evolution, including relevant AI‑first patterns
• Make key decisions on technology stack, system design, integration patterns, and responsible AI use
• Collaborate with Scrum teams to translate architectural principles into actionable solutions
• Provide technical leadership, mentoring, and sparring to developers, including AI best practices
• Challenge existing solutions and drive continuous improvement in code quality and engineering practices
• Ensure architecture aligns with business goals, product strategy, and AI guardrails for quality and security
• Stay hands‑on with coding and prototyping, leading by example rather than Power Point

• 5+ years of working experience with backend development in C# / .NET
• Professional experience using AI in software engineering workflows
• Azure or other cloud providers
• Rabbit
  
  MQ or similar message brokers
• MSSQL
• Entity Framework Core

Will be an advantage:

• Experience with AI engineering quality standards, review practices, and governance
• E2E testing technologies (like Cypress)
• CI/CD
• Infrastructure as code (Terraform)
• Docker/containerization
• Strong understanding of distributed systems
• A highly experienced software engineer who thrives on solving complex system challenges
• Demonstrates mature judgment and responsibility in how AI is used across engineering teams
• Comfortable taking ownership and making technical calls
• Pragmatic – balances ideal architecture with real‑world delivery needs
• A strong communicator who can explain why as clearly as how
• Passionate about building great systems, not just writing great code
