Department: Engineering The Engineering organization at Signifyd is at the forefront of building solutions that protect and empower global commerce. We pride ourselves on delivering highly scalable, robust systems that evolve with our customers' needs, from emerging startups to enterprise-level organizations processing millions of transactions. Our engineers thrive in an innovative environment where rapid iteration and continuous learning drive our success. We embrace modern development practices, leverage cloud-native technologies, and maintain a customer-obsessed mindset to ensure our solutions anticipate tomorrow's challenges. Strong partnerships with Product and Data Science ensure every technical decision is aligned with delivering maximum value and driving meaningful business outcomes. The Role We are looking for a staff back-end engineer to set the technical direction for the platform retailers use to integrate with Signifyd. As a member of the Integrations & Onboarding team, you will own the architecture and long-term health of our public-facing API platform and ingestion services, defining both what we build and how we build it. This role suits an engineer who is drawn to open-ended problems spanning several teams, who can turn a complicated problem space into simple and durable foundations, and whose influence shows up in other teams' roadmaps as much as in their own systems. Responsibilities • Define and deliver the multi-year technical vision for our integration and ingestion platform across multiple teams and competing constraints. • Make the architecture-level technology calls, including build-versus-buy decisions and framework selection, and own the tradeoffs behind them. • Own the overall health and engineering quality of the platform: drive health reviews, curate testing strategy, and ensure the systems stay maintainable by engineers with varying levels of expertise. • Design systems under significant ambiguity, particularly those that many other systems depend on. • Partner with product management, data engineering, and other engineering teams, influencing their roadmaps where a shared solution serves the business better than a locally optimal one. • Raise the technical bar across related areas through design and code review, with particular attention to cross-team interfaces and API quality. • Proactively identify areas of technical debt and drive the strategy for addressing them. • Serve as a role model and mentor for engineers across the organization, and champion responsible adoption of AI development tools. Requirements • Bachelor's degree or equivalent practical experience. • Significant experience in software development with modern programming languages, experience programming in a functional style. • Track record of setting technical direction across multiple teams, and of carrying large, ambiguous initiatives through to completion. • Depth in a platform or product domain that translated into distinctive business value, rather than
