The Role
At Partiful, Trust & Safety is a shared responsibility. We have always worked hard to protect our users and our platform, and now we're looking for an expert to deepen and accelerate that work across the entire company.
This role is a good fit for an backend-leaning engineer who has developed a specialization in trust and safety, or a T&S engineer who thinks and builds like an platform engineer. It’s a fast-paced, high-ownership role in an environment where we move quickly, set ambitious goals, and hold a high bar for speed and technical excellence. You’ll spend most of your time on T&S, including detecting, investigating, and mitigating risks including phishing, spam, objectionable content, scraping, and other forms of fraud and abuse, and some time on product infrastructure, reliability, performance, and developer velocity.
Our stack is React (web app), React Native (mobile app), Node.js, and Typescript, running on GCP with a serverless architecture.
What You'll Do
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 deeply across functions:
Partner 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
Join forces 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!
What You'll Bring
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.
What we offer:
401(k) with up to 6% matching
