• Embed AI-assisted development into daily workflows to improve coding speed, testing quality, documentation, and delivery efficiency.
• Contribute to architecture and technical design decisions for complex systems, balancing scalability, cost, and customer impact.
• Improve CI/CD pipelines (e.g., GitLab), increasing automation, deployment reliability, and engineering efficiency.
• Strengthen system reliability through improved monitoring, alerting, incident response, and post-incident learning practices.
• Mentor engineers through code reviews, pairing, and technical guidance, raising overall team engineering standards.
• Collaborate with global cross-functional teams to align on requirements, technical tradeoffs, and delivery outcomes.
• Develop AI-enabled capabilities that enhance automation, data processing, and customer-facing insights.
• Evaluate and improve AI-generated outputs, ensuring security, governance, and engineering quality standards are met.

Requirements:

• Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.
• 8+ years of software engineering experience in building and operating complex, scalable systems.
• Strong hands-on experience with .NET (C#) for backend services and React (TypeScript) for frontend development.
• Proven experience designing distributed systems and building RESTful and/or GraphQL APIs in production environments.
• Solid experience with AWS and cloud-native architectures.

• Strong knowledge of CI/CD pipelines (e.g., GitLab), Docker, and Kubernetes in production environments.
• Experience working with relational and/or NoSQL databases at scale.
• Strong testing mindset with experience in unit, integration, and end-to-end testing strategies.
• Demonstrated experience using AI tools to improve engineering outcomes such as productivity, quality, or automation.
• Strong communication skills in English, with ability to collaborate effectively in global teams.
• Strong ownership mindset, mentoring ability, and experience leading technical discussions.

Benefits:

• Competitive compensation package including base salary, bonuses, and paid time off.
• Private healthcare coverage including medical, dental, and life insurance (varies by location).
