Job Summary Your Career

• As a Senior Staff Software Engineer, you will be a technical cornerstone of our engineering organization. You will design, build, and scale highly complex, distributed microservices that power our enterprise ecosystem. This role requires a blend of deep hands-on technical expertise, systems thinking, and a passion for modern engineering practices. You won’t just write code; you will architect scalable systems, champion code quality, and pave the way for AI-driven development methodologies.

Qualifications Your Impact

• System Architecture & Design: Design and evolve highly scalable, resilient, and fault-tolerant distributed systems capable of handling enterprise-level throughput.
• Hands-on Development: Deliver high-quality, clean, and maintainable code using C# (.NET Core), Java, or Python within cloud-native microservice environments.
• Complex Integrations: Deconstruct and map intricate enterprise integrations, understanding how disparate systems interact to build cohesive, scalable solutions.
• DevOps & Automation: Drive containerization and orchestration strategies using Docker, Kubernetes, and OpenShift. Own and optimize modern CI/CD pipelines (GitHub, Jenkins, Artifactory).
• Engineering Excellence: Champion rigorous code reviews, robust testing frameworks, and strict API design standards (RESTful APIs). Constantly challenge the status quo to optimize performance and tech stack efficiency.
• Infrastructure as Code: Leverage AWS and AWS CDK to build and manage secure, scalable, and automated cloud infrastructure.
• Technical Leadership: Act as a force multiplier by mentoring peers, driving spec-driven development, and integrating next-gen AI tools into the team’s daily workflow.

Required Qualification

• 5+ years of professional experience in large-scale, enterprise-level software environments.
• 5+ years of deep hands-on development experience in C#, Java, or Python, with a strong emphasis on .NET Core in cloud-based environments.
• Expert-level understanding of Distributed Systems Design, including design patterns, caching strategies, and asynchronous messaging.
• Strong experience with containerization and orchestration technologies, specifically Docker, Kubernetes, and Red Hat OpenShift.
• Proven track record with AWS cloud environments and Infrastructure as Code (AWS CDK, Python, or equivalent).
• Deep experience designing, building, and securing REST APIs and developing automated testing/automation frameworks.
• Expertise with modern CI/CD tools (GitHub Actions/Workflows, Jenkins, and JFrog Artifactory).

Soft Skills & Leadership

• Exceptional cognitive capacity to grasp complex, heavily integrated legacy and modern system architectures.
• A fierce passion for code design, refactoring, and maintaining a high bar for engineering discipline.
• Excellent communication skills with the ability to articulate complex technical trade-offs to both technical and non-technical stakeholders.
• Preferred & Bonus Qualifications (The “AI-Forward” Edge)
• AI-Tool Driven Delivery: Familiarity or hands-on experience leveraging AI-assisted coding tools (e.g., Claude, Cursor, LLM prompts) to accelerate delivery and code generation.
• Spec-Driven Devel…
