Platform Engineer, Trust and Safety

Partiful • New York, NY

22h • $165,000 - $210,000

About The Position

Partiful is seeking a backend-leaning engineer with a specialization in trust and safety, or a T&S engineer who thinks and builds like a platform engineer, to join their team. This is a fast-paced, high-ownership role focused on protecting users and the platform. The role involves detecting, investigating, and mitigating risks such as phishing, spam, objectionable content, scraping, and other forms of fraud and abuse. Additionally, there will be some involvement in product infrastructure, reliability, performance, and developer velocity. The company's tech stack includes React, React Native, Node.js, and Typescript, running on a serverless architecture on GCP. Partiful's mission is to cultivate friendships through social events, and they are building new ways to streamline planning and connect people meaningfully in the real world.

Requirements

• 3–11 years of full-stack, infrastructure engineering, or applied machine learning experience in a fast-paced or high-growth environment
• 2+ years of experience in trust & safety; experience in consumer social is preferred but not required
• Experience building enforcement systems end-to-end: detection, action pipelines, escalation workflows, and appeals
• Fluency with common abuse vectors on consumer social platforms
• Experience with legal, regulatory, and compliance requirements for trust systems
• Experience designing and managing serverless or event-driven systems at scale
• Strong understanding of CI/CD workflows and best practices
• Experience with observability systems (such as Sentry, GCP Cloud Logging & Metrics Explorer)
• Solid grasp of networking, security, and performance tuning fundamentals
• Comfort working in Typescript/Node.js environments
• A builder's mindset — you enjoy automating, optimizing, and empowering teams through great tooling
• A habit of leveraging AI tools to move faster, debug smarter, and prototype more effectively
• Deep sense of ownership, dedication to delivering ambitious outcomes on fast timelines, and a bias towards action.

Responsibilities

• Architect and implement AI-powered systems for real-time decision-making and policy enforcement at scale, including the scaffolding to improve those systems over time
• Build observability tooling so the team can monitor abuse trends and respond to novel attack patterns quickly
• Balance risk and user experience: proactively monitor the impact of protective systems on trusted users, ensuring interventions deliver more value than friction
• Collaborate with Operations to define policy, translating ambiguous high-judgement calls into rules that are enforceable at scale
• Empower Support to handle enforcement — build out tooling, escalation paths, and appeal workflows the team and users can rely on
• Work with Data Science to build sophisticated, trustworthy threat and anomaly detection
• Collaborate with Product Engineering and Design to keep privacy and safety considerations at the core of our product
• Participate in an on-call rotation for Trust & Safety incidents and close the loop to prevent the next one
• Design, build, and maintain scalable, secure infrastructure across GCP's ecosystem (Cloud Functions, Firestore, Cloud Tasks, Redis, Pub/Sub, etc.)
• Collaborate with other engineers to design performant APIs, databases, and backend systems
• Drive the Trust & Safety roadmap, balancing safety investment against the broader needs of the business
• Join an ambitious team that moves fast, works hard, and loves what we build — and help shape the foundations and culture of T&S at Partiful!
