We are seeking an experienced Staff Software Engineer to play a critical technical leadership role within our Regulatory Reporting team. This role is responsible for designing, building, and operating highly reliable, auditable, and deterministic systems that support regulatory reporting across multiple jurisdictions.

As a Staff Engineer, you will be a hands-on technical leader, shaping architecture and standards across backend services and data-intensive workflows, while partnering closely with the Engineering Manager, Compliance, and Data Engineering teams to ensure regulatory obligations are met with precision and confidence.

Technical Ownership & Architecture:

  • Act as a technical authority for the regulatory reporting platform
  • Lead the design of backend services and data-intensive systems supporting regulatory submissions, report generation and validation, evidence, traceability, and audit workflows 
  • Drive architectural decisions that balance correctness, scalability, and operational reliability 
  • Ensure systems are deterministic, reproducible, and versioned to support audits and restatements  

Software Engineering:

  • Design and implement production-grade backend services using modern engineering practices 
  • Apply distributed systems principles including idempotency and safe retries, failure isolation and graceful degradation, schema and API versioning  
  • Build systems with clear SLAs, SLOs, and observability  
  • Maintain a strong security posture across services and data access 

Data-Intensive & Reporting Systems:

  • Work closely with data engineering teams on canonical data models, regime-specific reporting overlays  
  • Design software that integrates cleanly with analytical platforms and reporting datasets 
  • Backfills and historical restatements 
  • Late-arriving data and reconciliation logic 
  • Full lineage from source systems to reported figures 

Governance, Controls & Auditability:

  • Support regulatory audits, investigations, and remediation efforts 
  • Champion strong practices around access control, PII handling, and segregation of duties 

Technical Leadership & Mentorship:

  • Lead and participate in architecture and design reviews 
  • Mentor senior and mid-level engineers, raise the technical bar across the team 
  • Influence engineering standards without direct line management 
  • Partner closely with the Engineering Manager on technical strategy and execution
