· Technical design and architecture contributions, including evaluating tradeoffs, defining interfaces and patterns, documenting decisions, and helping the platform evolve without creating unnecessary complexity.

· End-to-end delivery of meaningful product capabilities, from refinement and estimation through implementation, code review, automated testing, deployment support, and post-release learning.

· Diagnosis and resolution of complex defects and production issues across application code, services, integrations, data flows, and Windows endpoint environments.

· Engineering quality through clear, testable code; thoughtful reviews; appropriate automated test coverage; observability; secure development practices; and disciplined source control.

· Technical collaboration and mentorship that raises the effectiveness of the engineering team, including sharing context, reviewing designs, pairing on difficult problems, and helping other engineers make sound implementation decisions.

· Practical use of AI-assisted engineering and agentic workflows to improve speed and leverage while protecting code quality, security, governance, and release reliability.

· Minimum of 8-10+ years of professional software development experience, including substantial hands-on experience building and supporting production applications in C# and .NET.

· Strong understanding of software architecture, object-oriented design, APIs, asynchronous processing, data access, integration patterns, and maintainable application design.

· Demonstrated ability to take complex features from ambiguous requirements through technical design, implementation, testing, release, and production support.

· Experience diagnosing difficult software problems using logs, metrics, traces, debuggers, profilers, and systematic root-cause analysis.

· A strong quality mindset, including experience with unit, integration, and automated testing; code review; source control; CI/CD; and reliable release practices.

· Working knowledge of relational databases and SQL, including data modeling, query performance, and application-level data access.

· Strong written and verbal communication skills, including the ability to explain technical decisions, risks, and tradeoffs to both engineering and non-engineering stakeholders.

· Experience working in Agile / Scrum teams and with Azure DevOps, GitHub, or similar planning, source control, build, and deployment systems.

· Comfort operating in a smaller, high-accountability growth company where senior engineers balance architecture, hands-on delivery, collaboration, and production ownership.

· Experience with BIOS, partitioning, Windows Registry, drive partitioning, Windows PE, and other system-level architectures.

· Experience building enterprise SaaS, endpoint management, Windows-based systems, cybersecurity-related products, IT operations software, or automation platforms.

· Experience with Windows internals, PowerShell, Microsoft cloud technologies, endpoint administration, or software that executes work across distributed devices.

· Experience with cloud services, distributed systems, messaging, REST APIs, authentication and authorization, third-party integrations, or high-volume job orchestration.

· Experience using AI-assisted development tools, agentic workflows, or AI-enabled testing in a disciplined production engineering environment.

· Developing the client's end point software platform including the Bot capabilities ship predictably and meet clear standards for correctness, security, performance, supportability, and rollback readiness.

· The AidenBot codebase becomes easier to understand, test, extend, troubleshoot, and operate as the product and customer base grow.

· Architectural decisions are pragmatic, well communicated, and aligned with both near-term delivery needs and the platform’s long-term direction.

· Complex defects and production issues are resolved methodically, with root causes addressed and lessons translated into better code, tests, telemetry, and engineering practices.

· Engineering teammates benefit from thoughtful design collaboration, constructive code review, clear documentation, and practical technical mentorship.

· AI is used thoughtfully as a force multiplier for engineering speed and quality without weakening security, maintainability, or accountability.
