Staff Backend Engineer - Content Platform

What you'll Do • Define the technical direction for policy enforcement infrastructure • Architect enforcement capabilities as a shared platform designed to be consumed by multiple product teams rather • Design and evolve multi-signal orchestration systems that enable configurable, auditable policy enforcement at scale across content types and product surfaces • Build the data foundation that makes enforcement decisions durable and reusable • Own the hardest API and contract decisions: schema design, versioning strategy, and how enforcement interfaces evolve without breaking the teams that depend on them • Establish integration standards for teams onboarding onto shared enforcement infrastructure, and work directly with consuming teams to execute migrations with clean cutoffs and clear end states • Influence architecture across detection, signal processing, and enforcement workflows so that the underlying primitives stay coherent as the platform scales • Mentor engineers and set the bar for how the team reasons about API design, data modeling, and the downstream compliance consequences of infrastructure choices Who You Are • Deep experience designing and operating large-scale distributed systems, APIs, event-driven pipelines, rule engines, and decision systems running in production across high-throughput environments • Proficient in backend engineering at scale, with strong command of languages like Java, Kotlin, Go, or similar; comfortable owning data models, service contracts, and storage layer decisions • Experienced with stream processing and event-driven architectures (Kafka, Pub/Sub, or equivalent) and the tradeoffs between batch and real-time enforcement pipelines • You have designed systems where schema and contract stability matter as much as correctness • Experienced with workflow orchestration and distributed coordination, whether through dedicated orchestration frameworks like Temporal or Airflow, choreography-based event systems, or hybrid approaches, and understand the tradeoffs between each in the context of long-running, stateful enforcement workflows • Experienced with relational and non-relational storage systems and know how to model enforcement data for auditability, immutability, and efficient querying at scale • You understand platform engineering patterns: multi-tenant APIs, configurable rule engines, policy-driven actioning systems, and the difference between building for one team and building for many • Familiar with observability and operational excellence, distributed tracing, structured logging, alerting, and the tooling that makes enforcement systems debuggable and auditable in production • You have worked in regulated or compliance-adjacent environments and understand how infrastructure design decisions, log retention, schema choices, data lineage, carry legal and audit consequences • You are comfortable in polyglot environments and can navigate existing systems thoughtfully rather than defaulting to greenfield rewrites • You think in systems end-to-end Where You'll Be • This role is based in London or Stockholm. • We offer you the flexibility to work where you work best!
