> Senior Software Engineer building fraud detection, risk decisioning, and Trust & Safety tooling for a nonprofit fundraising platform. Requires 6+ years experience building fraud/risk systems with strong backend fundamentals and stakeholder collaboration.

## Job Description

## What You’ll Do
- Build the fraud platform: Design and implement fraud detection and risk decisioning systems, rule engines, scoring pipelines, and event-driven risk signals.
- Build for operators: Create investigation and review tooling that helps our Trust & Safety operations team triage, investigate, and resolve cases efficiently.
- Help shape what we build next: Work closely with manager, product, and operations stakeholders to identify exposures, propose solutions, and prioritize the roadmap.
- Think like an adversary: Develop deep understanding of fraud vectors in fundraising and payments (stolen cards, synthetic identities, friendly fraud, campaign abuse) and build adaptive systems.
- Strengthen payment integrity: Work across payment systems to harden the transaction lifecycle against abuse.
- Mentor those around you: Help team develop Trust & Safety domain expertise, share knowledge, and unblock teammates through code reviews.

## Requirements
- 6+ years of software engineering experience, with experience in fraud, trust & safety, risk, abuse prevention, or adjacent domains.
- Experience building fraud detection or risk decisioning systems — rule engines, scoring systems, policy frameworks, or investigation platforms.
- Strong backend engineering fundamentals: Design scalable, event-driven systems and reason about distributed architecture tradeoffs. Debugged production issues across multiple layers of the stack.
- Stakeholder partnership: Partner closely with end-users and cross-functional stakeholders to discover problems, validate solutions, and iterate. Communicate clearly and turn ambiguous needs into shippable work.
- Good judgment and prioritization: Break down vague problems (e.g. "our dispute rate is climbing") into concrete plans.

## Nice to Have
- Experience with PHP/Laravel, or similar MVC framework (Ruby on Rails, Django, etc.). Laravel is a plus.
- Experience leading a project or feature area end-to-end.
- Experience with React/TypeScript on the frontend.
- Familiarity with Stripe's APIs, payments, disputes, Radar, or similar payment processor integrations.
- Experience building tools for operations or support teams (internal tooling, case management, review queues).
- Background in fundraising, nonprofit tech, or marketplace platforms.
- Exposure to event-driven architectures (CDC, Kafka, event sourcing) for real-time risk signal processing.
- Experience working in AWS (EKS/Kubernetes, RDS, etc.).
