Contract Full Stack / Backend Engineer III - Trust & Safety Platforms
Duration: 6-Month Contract (with potential for extension)
Location: 100% Remote (UK-based)
Inside/Outside IR35: Insert IR35 The Opportunity
We are looking for a Senior Full Stack / Backend Engineer (Level III) to join the Trust & Safety / Policy Platform team for one of the world's leading, household-name audio streaming platforms.
If you are a backend-heavy engineer who enjoys the autonomy of building robust APIs and crafting the internal web tools that power them, this contract is for you.
What You'll Do
Engineers at Scale: Build and scale the core APIs and services that expose complex policy logic across detection, enforcement, and compliance surfaces.
Data & ML Pipelines: Model data for strict auditability, versioning, and efficient querying, feeding structured datasets directly into downstream machine learning models.
Empower Internal Teams: Design and implement intuitive, responsive web interfaces that allow non-technical stakeholders (Legal, Operations, Trust & Safety) to author and manage content policies with robust approval workflows.
Ensure Compliance: Translate global regulatory requirements into airtight engineering constraints and audit trails.
What You'll Bring
This is a true full-stack role with a 70% Backend / 30% Frontend split. We need someone who is equally comfortable thinking about schema evolution as they are about frontend state management.
Backend Mastery: Strong production experience building high-scale services using Java, Kotlin, or Go.
Modern Frontend Skills: Hands-on experience building clean, intuitive internal tooling using React and TypeScript.
System Design & Integrity: Deep understanding of API design, backward compatibility, and data modeling for complex, versioned systems where stability is critical.
Data Savvy: Experience working with data pipelines and a solid grasp of the trade-offs between real-time and batch processing.
Mindset: An eye for usability. You know how to make high-stakes, complex workflows feel simple and foolproof for non-technical users.If you are interested in this role, please apply here or share your updated resume to (url removed)
