Software Engineer Finance Applications

• Build financial operations and reporting infrastructure - Design and implement backend services for Accounting FP&A Tax Procurement while keeping the company compliant.
• Lead a platform migration - Architect the migration of business-critical workflows from legacy vendor platforms to Block's internal systems ensuring zero disruption to agents and customers during cutover
• Design workflow and automation systems - Build configurable workflow engines rules-based routing and event-driven automations that reduce manual effort and scale across multiple business lines
• Own integrations end-to-end - Design build and maintain integrations between internal platforms and external systems ( middleware workforce management Oracle fusion Salesforce etc) using APIs event streams and messaging patterns
• Partner across the business - Work directly with operations compliance and product stakeholders to translate complex financial and regulatory requirements into well-architected technical solutions
• Ensure compliance and data integrity - Build systems with audit trails access controls and data governance baked in - not bolted on - to meet regulatory requirements across multiple jurisdictions
• Lead technical discussions - Drive architecture decisions contribute to design reviews and mentor engineers; raise the bar on code quality testing and operational reliability
• Direct AI agents across the full development lifecycle - from prototyping and implementation to debugging and code review - operating as the architect and decision-maker while AI handles the building
• Expand what's possible with AI tooling - identify opportunities to automate repetitive engineering work improve code quality through AI-driven review and share effective patterns with your team

• Embrace an AI-first mentality. Leverage AI to augment your knowledge and capability in navigating development in complex systems with confidence.
• Familiar with agentic engineering.
• 6+ working on complex systems and delivering quality software with clear expertise developed in one or more technical areas.
• Strong fundamentals in distributed systems design - you've built services that handle high throughput manage state across systems and degrade gracefully
• Experience with workflow or state machine systems - you've designed systems where entities move through complex lifecycles with branching logic SLAs and human-in-the-loop steps
• Proficiency in building and maintaining APIs and integrations - REST gRPC event-driven architectures and data synchronization across multiple platforms
• Experience working on financially sensitive or regulated systems - you understand why idempotency audit trails data retention and access controls matter and you build for them by default
• Strong collaboration skills and the ability to work effectively with non-technical stakeholders - translating ambiguous business requirements from operations compliance and risk teams into well-scoped engineering work

• A growth mindset and comfort navigating open-ended problems where the "right" answer depends on business context that's still evolving.
• Contributed to the growth of fellow engineers through technical leadership mentoring and setting engineering standards
• Demonstrated fluency with AI-assisted development tools (e.g. Claude Code Cursor GitHub Copilot or similar agentic coding tools) in real production work - not just familiarity but regular effective use
• You stay current on the rapidly evolving landscape of AI tooling and actively experiment with new capabilities as they emerge

• Curiosity that pushes you to find flaws in complex systems and take whatever steps are necessary to fix them.
• Resilience to persevere in complex situations across multiple axes: e.g. scale uncertainty and interconnectedness.
• Self-directed and comfortable with ambiguity with a willingness to publish your reasoning and be wrong publicly-which is essential for thriving in our transparent DRI/IC model

• Experience with platform migrations - moving business-critical systems between platforms with zero customer impact and phased rollout strategies
• Background in financial services domains - accounting revenue forecasting treasury operations tax operations.
• Experience building multi-tenant or multi-BU platforms - systems that serve different business lines with shared infrastructure but configurable behavior
• Experience with operational analytics - building data pipelines or reporting systems that give operations leaders real-time visibility into performance

• AI-Driven Development: Claude Code Goose (Block's open-source AI agent) Cursor GitHub Copilot Anthropic's Model Context Protocol (MCP)
• Languages: Kotlin Java Python JavaScript
• Protocols: HTTP JSON gRPC Protocol Buffers
• Data: DynamoDB MySQL Kafka Snowflake
• Infrastructure: AWS Kubernetes
• Observability: DataDog Prometheus
• Feature Management: LaunchDarkly
