Job description

Why We Stand Out

Seeking a career-defining opportunity where your leadership, strategic vision, and client expertise are recognized and rewarded? Kaufman Rossin might be just the place for you.

As one of the top accounting firms in the country, our foundation is “people first.” In the words of James Kaufman, “we prioritize our people, their development, and their well-being. Our values are translated into action every day.”

Kaufman Rossin is a privately owned, independent public accounting firm, which means we are not beholden to outside investors or private equity influence. This independence allows us to prioritize long‑term client relationships, maintain objectivity in our advisory approach, and make strategic decisions that benefit our people and clients, not external stakeholders. Our structure fosters agility, entrepreneurial thinking, and a collaborative culture where leadership is accessible, and innovation is encouraged.

Celebrated as the Best Place to Work in South Florida over a dozen times, Kaufman Rossin has grown to over 700 employees, with offices spanning the tri‑county area, including sister entities Kaufman Rossin Wealth and Kaufman Rossin Alternative Investment Services.

Think you have what it takes?

How You'll Contribute

Kaufman Rossin is seeking a Senior Software Engineer to join our growing Information Technology team. In this role, you’ll help shape the future of KR’s application portfolio by delivering high quality features, modernizing legacy services, reducing technical debt, and standardizing development tools and practices. You’ll work across WES, including WES API, WES UI, Hermes, and Workstreams, and collaborate closely with KR’s global delivery team in Bengaluru.

• Build and maintain production features across WES API using Python and FastAPI, WES UI using React and TypeScript, Hermes, and Workstreams
• Develop business logic and AI workflows using Python and FastAPI
• Contribute to systems and performance critical components using Rust, Axum, and Tonic
• Build reusable React components using the selected component library, including Tailwind with Radix or Fluent UI
• Use React Query for server state and Zustand for client state while supporting the migration from legacy Apollo and Redux patterns
• Implement real time functionality using Azure SignalR Service
• Develop event driven solutions using Azure Event Hubs and Kafka compatible messaging patterns
• Integrate applications with Azure Entra ID using OAuth 2.0, OpenID Connect, and JWT standards

Technology Consolidation & Tech Debt Reduction

• Assess technical debt, document effort and risk, and develop phased migration plans that minimize production disruption
• Support the migration of AWS workloads to Azure, including EKS to AKS and Cognito to Entra ID
• Help reduce KR’s language and framework footprint by transitioning Ruby, Go, Node.js, Express.js, and Ember.js services toward Python, Rust, and React standards
• Consolidate observability tools into Azure Monitor, Application Insights, and Azure Managed Grafana
• Consolidate security tools using GitHub Advanced Security, Microsoft Defender for Cloud, and Azure Key Vault
• Contribute to retrieval augmented generation technology decisions involving Azure AI Search, HelixDB, and TensorZeroCode

• Author and enforce ADRs — document technology choices, migration decisions, and trade‑offs
• Maintain CI/CD pipelines in GitHub Actions (or Azure DevOps Pipelines where applicable)

Global Delivery Team Partnership

• Work as a true partner with KR's Bengaluru development team
• Participate in cross‑regional agile ceremonies: standups, sprint planning, reviews, retrospectives

• Mentor less‑experienced developers on the global team: code reviews, architecture Q&A, knowledge transfer

AI-Integrated Application Development

• Integrate AI capabilities into WES, building on Azure AI Search + HelixDB + TensorZero gateway for document intelligence and semantic search
• Contribute to prompt engineering and retrieval optimization within the application layer
• Build React components, API endpoints, and streaming response handlers that surface AI features reliably

How You'll Stand Out

• Working Rust: able to read, extend, and contribute to axum/tonic services; clippy fluency
• Event‑driven architecture like Kafka
• Identity/auth systems: OAuth2/OIDC, JWT, Azure Entra ID or equivalent
