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 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 systems stay maintainable.
• 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.
• Raise the technical bar across related areas through design and code review, focusing on 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, with experience programming in a functional style.
• Track record of setting technical direction across multiple teams, and carrying large, ambiguous initiatives through to completion.
• Depth in a platform or product domain that translated into distinctive business value.
• Strong software design and architecture skills, reducing complex problems to simple foundational components.
• Experience owning the long-term health of a significant system: testing strategy, operability, and reducing key-person dependency.
• Experience building distributed systems or public-facing/platform APIs at scale.
• Experience with cloud platforms such as AWS or GCP.
• Ability to influence without authority and communicate effectively with engineers and non-engineers.
• Fluent use of modern AI development tools with practical experience using AI coding assistants and evaluating generated code.
