Cloudflare · London · £185,000 – £254,000 pa

Owns the request-facing layer of Cloudflare's R2 object storage: the S3-compatible API gateway handling authentication, routing, rate limiting and error handling. Builds and operates high-throughput services on Cloudflare Workers and Kubernetes, with on-call rotation and heavy use of AI tooling in daily development.

Cloudflare · London

Join the Workers Runtime team to build and improve the runtime that executes customer code at Cloudflare's edge. You'll work on performance, reliability and scale, expand JavaScript API and WebAssembly support, and own code in production within a large-scale distributed system.

Nebius · London

Owns focused research projects on efficient LLM and VLM inference, spanning quantization, distillation, speculative decoding, KV-cache optimization, and model/runtime co-optimization. Builds prototypes in PyTorch, Triton, and serving frameworks, evaluates trade-offs across latency, throughput, memory, and cost per token, and works with engineering teams to move results into production.

Nebius · London

Owns model and endpoint optimization for LLM and VLM serving, from quantization and compression to speculative decoding, KV-cache tuning and distributed inference architecture. Works with kernel and platform engineers to diagnose regressions and scale dense and MoE inference across multi-node GPUs, validated by reproducible benchmarks.

Amazon · London

Leads strategic AI-driven digital product delivery transformation for enterprise customers adopting Amazon Kiro and AWS generative AI services. Defines repeatable methodologies, maturity models and assessment frameworks, co-develops offerings with consulting partners, and monitors customer transformation health. A senior individual contributor role in the AWS Specialists & Partners Customer Success Center of Excellence.

Amazon · London

Supports Interconnect Business Developers by coordinating embedded cache deployments with external ISPs, owning the process from contract signing through CloudFront provisioning. Involves site validation, troubleshooting failed installs, documentation, reporting, and driving process improvements, new tools and automation across a global network.

Nebius · Amsterdam, Netherlands; Israel; Remote - Europe; United Kingdom

Conducts applied AI research on reinforcement learning, guided search and agent training, running large-model experiments across multiple compute nodes. Works in Python and JAX on reasoning models, distillation and web-scale data collection, publishing findings and collaborating with adjacent teams.

Nebius · London

Builds and owns core components of a GPU-native serverless AI platform, spanning control plane, scheduler, runtime, autoscaler and customer-facing APIs. The role is end-to-end and high-ownership, tackling cold-start latency, GPU scheduling under contention, multi-tenant isolation and edge request routing while running the service with SRE practices.

Nebius · London

A talent pool for engineers and technical specialists interested in future roles across AI, cloud and high-performance computing, covering areas such as LLM pre- and post-training, inference optimisation, GPU and distributed infrastructure, and backend or platform engineering. It is an expression of interest rather than an application for a specific vacancy, aimed at attendees of the Nebius AI Series in London.

Nebius · London

Builds and maintains web access infrastructure for an agent-native search platform, diagnosing failed requests across network, TLS, HTTP/2 and browser layers. Develops browser-compatible clients and tooling, choosing fetch methods per host and tracking success at internet scale. Requires deep protocol, fingerprinting and client-side analysis expertise.

Nebius · Israel; Netherlands; Remote - Europe; United Kingdom

You will modify Chromium's core (Blink, V8 integration, compositor, network service) to cut CPU, memory and startup cost per page, stripping out image/media decoding, font downloads and GPU work for agent workloads while preserving script behaviour. The role also covers profiling browser fleets, managing process models and building launch, pooling and recycling infrastructure.

Nebius · London

Builds and operates web-scale crawling and ingestion infrastructure for an agent-native search platform, handling billions of URLs with a focus on coverage, freshness and reliability. Involves crawl scheduling, URL discovery, deduplication, content extraction and observability, working closely with indexing and ML teams.

Nebius · United Kingdom

Builds fault-tolerant, reliable cloud services across cloud infrastructure, managed databases, managed Kubernetes, billing, monitoring and ML services. The stack is primarily Golang with some Java and Python, and the team tackles large-scale GPU orchestration and inference optimisation. Coding interviews are part of the process.
