Job description

About

Do you want to shape the architecture behind Continia’s products and drive technical excellence across our backend platform?

We’re looking for a highly skilled engineer who combines deep hands‑on expertise with the ability to design scalable systems, influence technical direction, and mentor others.

About the Role

Your work will form the foundation of Continia’s products — powering cloud services, APIs, and integrations used by thousands of businesses worldwide. You’ll design and implement backend systems that handle millions of transactions, ensuring reliability, performance, and security at scale.

This role blends system technical leadership while being hands‑on. You’ll architect solutions, write core services, and define standards that raise the bar for backend engineering across Continia. Working closely with frontend engineers, product managers, and architects, you’ll help shape the future of our platform — balancing innovation with long‑term maintainability.

Key Responsibilities

• Drive architectural direction for backend services across Continia’s product suite.
• Design and build scalable APIs, integrations, and distributed systems using .NET and Azure.
• Develop secure, high-performance, and observable services that scale globally.
• Evaluate and implement new technologies, frameworks, and tools that improve developer velocity and system resilience.
• Collaborate with engineers across teams to review designs, share knowledge, and maintain technical consistency.
• Act as a mentor — guiding others through design reviews, code feedback, and architectural discussions.
• Contribute to broader engineering initiatives, including CI/CD pipelines, automation, and cloud infrastructure improvements.

What We’re Looking For

• Deep experience in backend development with C\#/.NET.
• Strong understanding of distributed systems, cloud architecture (preferably Azure), and modern API design.
• Solid database knowledge (SQL Server/Azure SQL) and data modeling skills.
• Experience with event‑driven or message‑based architectures.
• Strong focus on scalability, performance, and security.
• A pragmatic mindset — able to simplify complex systems and balance delivery with long‑term vision.
• Excellent collaboration and communication skills.
• Passion for craftsmanship and for helping others grow through mentorship and example.
