## About the Role

Do you have experience in SQL?, Extensive experience building backend systems with .NET (typically 8+ years, though we care more about demonstrated depth than years).

 - Strong understanding of API design, distributed systems, and asynchronous architectures.

 - Experience with SQL and NoSQL databases (PostgreSQL preferred), caching, and queuing systems.

 - Familiarity with cloud environments and DevOps practices (Azure preferred).

 - Comfortable working on production SaaS platforms, with ownership beyond deployment.

 - Experience using AI-assisted development tools (e.g. Cursor or similar) to support code exploration, refactoring, testing, or design discussions - while maintaining strong engineering judgment.

 - A strong sense of ownership and production accountability, including monitoring, debugging, and continuous improvement.

 - Ability to understand product and business context, making pragmatic technical decisions that balance user value, risk, and long-term goals.

 - A security-conscious mindset, building systems that are secure by design.

## Description

Design, build, and maintain scalable backend services for Keepnet's Human Risk Management platform.

 - Build clean, modular APIs that integrate internal services and third-party systems to enable automation, reporting, and security workflows.

 - Develop testable, maintainable codebases using principles such as Clean Architecture, DDD, and TDD.

 - Own the full development lifecycle: design, implementation, CI/CD (Azure), and post-release monitoring.

 - Work on distributed and asynchronous systems using message queues, background workers, and event-driven workflows.

 - Use observability signals (logging, metrics, tracing, tools like Sentry) to proactively detect, diagnose, and prevent production issues.

 - Collaborate closely with frontend, product, and customer-facing teams to deliver features that solve real customer problems.

 - Participate in Agile ways of working, focused on iteration, ownership, and continuous improvement.
