Software Engineer, Finance Applications

About the role

The Financial Platform Eng team is part of Block's platform engineering org, with a mandate to run the foundational financial technology infrastructure supporting all our brands. Our charter includes building scalable, reliable, and forward-looking financial infrastructure, from revenue streams to reconciliations to GL to street reporting. This team powers key business functions spanning the CFO org and aids at strategic decision-making.

Responsibilities

• 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 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.

Requirements

• Familiar with agentic engineering.
• 6+ years of 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.
