Backend Developer, C# Specialist I

Role Overview

As a specialist on the team, your day-to-day will include:

• Development and Engineering: Work across the full development cycle (design, coding, testing and deployment) of systems, actively contributing to the definition of architecture and code standards.
• Ownership and End-to-End Vision: Take strong ownership of the product, being responsible not only for delivering code but for the success of the solution in production.
• Efficiency with Artificial Intelligence: Integrate generative AI tools and code-assistants into the daily workflow to accelerate productivity, improve code quality and drive innovation in solving complex problems.
• Operational Efficiency and FinOps: Monitor and optimize cloud resource consumption, applying FinOps practices to ensure the architecture is scalable and cost-effective, minimizing waste.
• Flow Management and Metrics: Track team efficiency indicators and agile metrics, proactively identifying bottlenecks, optimizing delivery cadence and ensuring a healthy, predictable workflow.
• Culture of Accountability: Proactively identify technical debt and improvement opportunities, taking responsibility for the continuous evolution of the ecosystem without constant external direction.
• Technical and Product Collaboration: Collaborate with other specialists and Product Managers (PMs) to refine business rules, ensuring solutions are robust, scalable and feasible.
• Quality and Stability: Ensure the robustness of deliveries through automated testing and proactive monitoring (telemetry), aiming for ecosystem stability.
• Operational Excellence: Participate in resolving complex incidents and support operations, ensuring that technical learning is applied to product improvements.
