Senior Machine Learning Engineer

The opportunityAn AI company is building systems to help organisations detect and respond to disinformation attacks in real time. The platform combines machine learning, proprietary knowledge of attack and defence techniques, and large-scale, high-throughput data analysis. The founding team brings over forty years of combined experience building data systems used by national security and commercial organisations.This is a high-ownership, production-focused role - not research. The focus is on real-world systems that are reliable, scalable, and fast.The roleYou'll build and operate production-grade machine learning systems that detect and counter disinformation as it happens. You'll work across the full ML lifecycle - from model development to deployment and monitoring - collaborating with a cross-functional team from software engineering, machine learning, and intelligence backgrounds.You'll shape both the product and the underlying ML infrastructure.What you'll work onBuild and operate production ML systems for real-time disinformation detectionOwn the full ML lifecycle: data, models, deployment, monitoring, and iterationDesign systems that balance latency vs accuracy, cost vs performanceWork across relational and non-relational databases and large-scale data processing pipelinesContribute to ML infrastructure and help define how the team buildsWhat we look forProduction ML experience - you've built and deployed ML systems in production, not just prototypesStrong engineering fundamentals - clean, modular, maintainable code that others can build onEnd-to-end ownership - from raw data through to deployed, monitored systemsAlgorithmic versatility - broad exposure across ML approaches; you apply the right method to the problemData systems experience - solid grounding in SQL and NoSQL, streaming and batch processingSystems thinking - you design for trade-offs, not just for accuracyInfrastructure familiarity - containerisation, CI/CD, production cloud environmentsStackPython · SQL & NoSQL databases · streaming & batch data processing frameworks · Docker · CI/CD · cloud infrastructureBenefitsCompetitive salary + early employee equity (share options)25 days holiday + your birthday offPrivate pension contributionsRemote-first, flexible, outcomes-driven cultureHigh ownership from day one
