Role Summary
Hands-on technical leader for enterprise applications across .NET, Python, and React. Owns architecture, incremental modernization of legacy systems, API and database engineering, and production reliability - while mentoring engineers and continuing to write code.
This is an onsite based position in Santa Clara, CA
Key Responsibilities
Solution design & modernization

• Own architecture, design, and technical direction for a portfolio of DIA applications.
• Translate business requirements into solution architecture, API contracts, data models, implementation plans, and testable acceptance criteria.
• Lead incremental, risk-managed modernization of legacy .NET, Web Forms, Angular, and scheduled-job applications - retaining and modernizing .NET where it fits, moving to Python/FastAPI where it advances platform convergence.
• Maintain backward compatibility and business continuity for consuming applications throughout.

Hands-on delivery

• Build and review backend services in C#/ASP.NET/.NET Core and Python/FastAPI.
• Build and review React/TypeScript front ends.
• Design secure, versioned, documented REST APIs and enterprise integrations.
• Optimize performance via query tuning, indexing, caching, pagination, batching, and async processing.

Production engineering

• Establish exception handling, structured logging, distributed tracing, metrics, dashboards, alerts, and health checks.
• Lead root-cause analysis on critical incidents through documented closure and preventive action.
• Diagnose issues across code, database, integration, infrastructure, and platform layers.

Standards & governance

• Define and enforce engineering standards for architecture, coding, testing, security, observability, and production readiness.
• Lead design, architecture, code, and release-readiness reviews.
• Ensure compliance with security, privacy, access-control, and change-management requirements.

Leadership & collaboration

• Lead multiple concurrent initiatives, balancing modernization, feature delivery, technical debt, and production support.
• Partner with product owners, architects, QE, infrastructure, cybersecurity, and support teams; coordinate globally distributed Agile teams.
• Mentor engineers; contribute reusable patterns, reference implementations, and accelerators.
• Communicate decisions, dependencies, risks, and status clearly to engineering and senior leadership.
• Use approved AI-assisted engineering tools within required security and engineering controls.

Qualifications
Education - Bachelor's in Computer Science, Software Engineering, Information Systems, or related technical field. Equivalent experience considered per company policy. Cloud/technical certifications desirable.
Experience - 6+ years in enterprise application development, architecture, integration, or modernization, including:

• Full lifecycle ownership from requirements through production support.
• Leading technical solutions spanning .NET, Python, React, REST APIs, SQL, and enterprise integrations.
• Leading medium-to-large initiatives with multiple technical and business stakeholders.
• Resolving complex production issues and driving preventive improvements.
• Mentoring engineers while contributing directly to delivery.
• Working with globally distributed Agile teams.

Technical Requirements
Backend C#, ASP.NET, .NET Framework/.NET Core, REST Web APIs; Python with FastAPI or comparable
Frontend React, TypeScript, JavaScript, HTML, CSS; working knowledge of Angular for legacy modernization
Architecture Enterprise application architecture, integration patterns, distributed systems, microservices, API-first design, event-driven integration, cloud-native patterns; design documentation (sequence diagrams, data-flow diagrams, API specs)
API & Security Versioning, OAuth 2.0/OIDC, JWT, RBAC, service-to-service auth, secrets management, validation, auditability; identifying breaking changes in routes, models, auth, and downstream integrations
Data Strong SQL on SQL Server and PostgreSQL; stored procedures, schema and index design, execution plans, connection management; diagnosing slow queries, blocking, locking, and timeouts; migration, archival, and retention practices
Cloud & DevSecOps Azure or AWS, containers, Kubernetes/OpenShift; Git-based workflows and PR reviews; CI/CD with automated build, test, deploy, rollback; dependency and vulnerability management
Observability OpenTelemetry, Splunk, Application Insights, or comparable - preferred
Quality Unit, API, integration, regression, performance, and production-readiness testing; automated quality gates in CI/CD; resiliency and negative-path coverage on critical integrations
Tooling Jira, Confluence, GitHub/Bitbucket, Azure DevOps; Scrum or SAFe; requirement-to-release traceability; approved AI-assisted development tools (desirable)
Competencies
Functional knowledge - Advanced command of enterprise architecture, full stack development, API and database engineering, cloud, testing, observability, security, and production support. Understands how frontend, backend, data, infrastructure, and business-process layers interact. Applies technical judgment in ways that protect continuity and avoid unnecessary modernization risk.
Business expertise - Develops deep understanding of the business processes each application supports; connects design decisions to operational continuity, data quality, reliability, and delivery speed; evaluates solutions for feasibility, risk, supportability, and lifecycle cost.
Leadership - Sets technical direction and standards across multiple applications; leads reviews and technical decision-making; influences without relying on authority; escalates material risks with clear recommendations; drives accountability, documentation, and knowledge transfer.
Problem solving - Reduces ambiguous problems to clear statements, options, and recommended actions using logs, traces, metrics, code, and database analysis. Determines whether the fix is code, architecture, database, integration, infrastructure, or process. Designs for failure with resiliency, monitoring, and recovery built in.
Impact - Improves quality, reliability, performance, security, and maintainability across the portfolio; enables continuity of critical DIA applications; raises engineering productivity through reusable patterns, automation, and standardized practice.
Interpersonal - Explains complex technical matters clearly to engineers, business partners, and senior management; aligns stakeholders on direction and priorities; documents decisions, risks, and operational procedures; works independently with transparency and accountability.
