Senior Software Developer I

Responsibilities

• Design and document the system architecture for assigned products, recording key decisions and trade-offs.

• Monitor delivered features after launch and act on feedback, bugs and performance issues.

Security, Reliability & Observability

• Apply secure development practices across products, including threat modelling and secrets management.
• Design and maintain authentication and access control so each client’s data stays separate.
• Ensure every service has logging, monitoring, alerting and backups, with tested recovery procedures.
• Maintain CI/CD pipelines and Azure cloud infrastructure, keeping hosting costs under control.
• Lead the response to production incidents, identify root causes and put preventive fixes in place.
