Role Overview and Focus

Role summary: The Tech Lead will own maintenance and operational excellence for a complex C# codebase used for data ingestion and analysis. The same codebase supports both on‑premise and SaaS deployments, so the lead will coordinate development and maintenance across both environments.

Primary focus: This is a maintenance‑driven role. Day‑to‑day work centers on customer ticket resolution, dependency updates, stability improvements, and targeted fixes rather than greenfield development or major architectural redesigns.

Key Responsibilities:

• Lead maintenance of a complex C# service suite responsible for event collection, processing, and analysis.
• Manage customer support tickets and participate in live troubleshooting sessions with end users.
• Ensure system stability by updating dependencies, fixing infrastructure and data bugs, and improving reliability.
• Mentor and guide team members to help them navigate the codebase and avoid getting lost in system complexity.
• Coordinate cross‑stack work: backend C# services, JS APIs, and JS frontend interactions.
• Communicate clearly with customers and internal stakeholders about issues, fixes, and expectations.

Required Experience and Skills:

• 10+ years of professional software development experience.
• Proven experience with large, complex systems and long‑running codebases.
• Strong C# expertise; familiarity with semi‑functional programming patterns.
• Comfortable working across the same codebase deployed for both on‑premise and cloud (SaaS) environments.
• Full English proficiency for customer interaction and team communication.
• Excellent communication and troubleshooting skills; able to lead live debugging sessions with customers.
• General infrastructure experience is required; domain‑specific knowledge (security, Active Directory) is not mandatory.

Tech Stack:

• Backend: C# services for event collection, processing, and analysis
• APIs: JavaScript
• Frontend: JavaScript
• Deployment: Cloud hosting for SaaS; on‑premise deployments share the same codebase
• Security background: Helpful but not required
