Responsibilities
KEY PERFORMANCE OBJECTIVES (First 12 Months)
OBJECTIVE 1: Master Project Domain, Architecture & User Workflows (First 4 Weeks)
Outcome:
Within the first 4 weeks, develop a complete understanding of the assigned systems, including architecture, business workflows, module responsibilities, dependencies, data flows, customer use cases, and integration points. Deliver a 10-15 minute presentation to the development leaders demonstrating technical fluency, an understanding of user needs, and clarity on how your work contributes to business value.
Impact:
Rapid mastery of the domain enables earlier meaningful contributions, reduces rework due to misunderstanding, and strengthens alignment between engineering decisions, customer workflows, and architectural direction.
How:
Meet with architects, team leads, SMEs, end users, and cross-functional partners to map requirements and workflows. Review architecture diagrams, repositories, backlog items, and sprint history. Walk through real user scenarios to understand functional expectations. Consolidate findings into diagrams, notes, and a concise leadership presentation.
OBJECTIVE 2: Build a Professional Development & Agile Contribution Plan (First 6 Weeks)
Outcome:
Within the first 6 weeks, create a structured personal development and contribution plan detailing technical upskilling goals, story-point velocity expectations, testing and automation commitments, code review responsibilities, and specific recommendations for improving team processes and methodologies. Review the plan with the hiring manager and finalize it with feedback incorporated.
Impact:
A targeted growth and contribution plan accelerates the path to full productivity, strengthens sprint predictability, and supports ongoing improvement of engineering quality and Agile execution.
How:
Assess skill gaps, analyze sprint history, review engineering standards, and gather feedback from senior developers and the Scrum Master. Convert insights into measurable objectives, commitments, and process improvement recommendations aligned with team needs.
OBJECTIVE 3: Build, Optimize & Maintain Cloud-Native Enterprise Solutions (Ongoing)
Outcome
Design, build, and maintain production-ready features and enhancements for cloud-native enterprise tax, accounting, reporting, and workflow applications. Deliver high-quality code using:

• Modern .NET (C#, ASP.NET Core with async/await, performance tuning, REST/GraphQL APIs)
• Angular with TypeScript (component architecture, lazy loading, module design)
• Reactive programming with RxJS and NgRx
• Relational database engineering (schema design, SQL optimization, Azure SQL/SQL Server)
• Azure cloud services (App Services, AKS, Service Bus, API Management)
• Achieve consistent sprint throughput, stable production performance, and low defect escape rates.

Impact:
High-quality, scalable code enhances system reliability, customer satisfaction, and product competitiveness. Strong engineering practices reduce operational risk and support ongoing modernization efforts in a mission-critical enterprise platform.
How:
Implement features, refactor legacy areas, optimize backend APIs, build Angular components with clean state management, design and tune SQL structures, and deploy/operate solutions on Azure. Use CI/CD pipelines, test automation, code reviews, performance diagnostics, and structured AI-assisted development (BMAD) to deliver predictable, high-quality increments.
OBJECTIVE 4: Operate as a High-Trust, High-Accountability Scrum Team Member (Ongoing)
Outcome:
Contribute consistently and transparently to Agile ceremonies-standups, refinement, planning, reviews, and retrospectives-while delivering committed work with high quality and predictable velocity. Engage in accurate estimation, clear communication, constructive code reviews, and proactive risk identification. Model behaviors aligned with The Five Dysfunctions of a Team: trust, healthy conflict, commitment, accountability, and focus on results.
Impact:
Strong collaboration and accountability reduce rework, improve sprint flow, and strengthen team delivery. High-trust team behavior directly increases quality, velocity, and customer impact.
How:
Provide clear updates, surface blockers early, refine stories with product and SMEs, share knowledge, pair with teammates, and contribute to continuous improvement. Engage openly in retrospectives, adopt agreed changes quickly, and support a culture of healthy debate and shared success.
