Principal ML/Systems EngineerArchitect Track | Hands-on IC | No People ManagementThe RoleYou are a senior individual contributor responsible for designing, building, and running large-scale backend and data systems. This role is about architecture, code, and production ownership - not people management.What You’ll DoBuild and operate large scale data pipelines and data lakes (real-time + batch)Design and build high-throughput, low-latency backend systems at scaleArchitect distributed systems that handle large volumes of data reliablyOwn production reliability: uptime, failure modes, recovery, on-call readinessDesign secure APIs and services (auth, rate limits, isolation, abuse prevention)Make clear architectural trade-offs across performance, cost, and complexityWrite and review critical-path codeInfluence engineering quality through design docs and code reviewsBuild systems that support AI / intelligent workloads as part of the platformWhat You BringProven experience building backend systems in production at scaleStrong systems thinking: throughput, concurrency, failure handlingHands-on experience with cloud infrastructure and distributed architecturesAbility to choose and use the most appropriate language or runtime for the problem at hand, and move fluently between ecosystems as neededExperience with datastores, queues, streams, and storage systemsExperience leading or executing system migrations (monolith → services, data migrations, infra or runtime transitions) with minimal downtime and risk Strong instincts around security, observability, and operabilityAbility to use frontier models effectively to generate the majority of production code, while retaining full ownership of design, correctness, and reliabilityCalm and effective during P0 / production incidentsHow We WorkWe optimise for deep work and uninterrupted time  High ownershipDecisions backed by code and production outcomesHow to ApplyShow systems you’ve built, scale you’ve handled, and problems you’ve owned.
