We are recruiting for a global platform looking to hire a Senior Full Stack Engineer for their Policy & Safety Content Platform group.

Please Note: To be considered, you must have proven experience working within a product-based company environment (SaaS, Tech Scale-up, or Big Tech) where you have owned features long-term. Candidates whose experience is predominantly within IT consultancies, agencies, or system integration environments will not be eligible.

• End-to-End Ownership: Build robust Back End APIs and services alongside intuitive, responsive web frontends.
• System Architecture: Expand a central policy registry, handling data modelling for auditability, strict schema versioning, and backward compatibility.
• Internal Tooling: Turn complex, compliance-heavy approval and review workflows into simple, usable web applications for non-technical internal teams.
• Data Pipelines: Construct data pipelines that feed structured data into downstream machine learning models and enforcement systems.

• The Stack: Strong Back End capabilities in a language like Java, Kotlin, or Go, paired with solid production experience building frontends in React and TypeScript.
• Product Mindset: You treat internal stakeholders as your customers. You know how to design internal tools that make complex tasks feel simple.
• Data & Architecture Savvy: You understand schema evolution, data versioning, and the trade-offs between Real Time and batch data pipelines.
• Regulated Environments: Experience or a strong interest in working with audit trails, compliance, fraud detection, or trust and safety systems is a massive plus.

Apply: Please submit your CV highlighting your relevant experience, or you may share it with me directly via email.
