Security Lead responsible for designing and assuring security across Callosum's full-stack AI orchestration platform—APIs, orchestration software, agentic systems, and physical compute—while building and leading the security team.
Callosum is seeking an ML Research Scientist to develop foundational intelligent systems by researching model architectures, learning algorithms, and efficient training methods. The role involves end-to-end research ownership, from hypothesis generation to large-scale implementation, working across a full-stack infrastructure.
Research Engineer building benchmarks and evaluation suites for agentic AI systems—designing rigorous measures for multi-turn, tool-using LLMs, turning traces into structured evidence, and building evaluation/observability infrastructure the whole company relies on.
Builds the runtime and programming model for long-running AI agents that run for weeks across distributed infrastructure, focusing on durability, observability, and secure tool execution.
ML Research Engineer at Callosum designing experiments to understand why agentic AI systems fail, building evaluation infrastructure, and publishing findings to improve heterogeneous model/hardware orchestration.
Build and improve an LLM-guided evolutionary search system that iteratively generates, evaluates, and optimises programs across kernels, inference runtimes, and scheduling policies, working with optimisation and search algorithms at an AI infrastructure startup in London.
Build and own a unified benchmarking system for evaluating agentic and algorithmic LLM solutions at Callosum's London office, using Python, sandboxed execution, and distributed systems to produce reproducible, contamination-controlled evaluation results.
Build the networking and interconnect systems that let heterogeneous AI accelerators communicate efficiently, spanning RDMA, programmable NICs, memory movement, and cluster fabric strategy at Callosum's London office.
Build and optimize OKX’s big-data platform for on-chain analytics, fraud detection, and AI-driven trading tools using Spark, Flink, Kafka, and vector databases.
Designs and delivers employee onboarding and learning programs in Ho Chi Minh City, partnering with teams to improve performance and development through structured training and events.
QA Engineer tests AI-driven products, including LLM platforms, by evaluating model responses, prompt robustness, and API integrations while handling non-deterministic behavior and edge cases.
System analyst at Sberbank’s Ecosystem Product Factory who gathers, models, and documents requirements for cross-channel sales platforms, designs microservices logic, and integrates systems via REST API, Kafka, and Camunda.
Design memory architectures for AI models to store, retrieve, and exploit experience across modalities, improving long-horizon behavior and production-ready learning systems.
Designs and builds scalable data pipelines and platform services for a quantitative investment firm, using Python and cloud technologies like AWS.
Lead Network Engineer owning the performance, reliability, and scalability of Halter's LoRa-based wireless IoT collar-to-tower network, ensuring real-time telemetry delivery across rural farm environments.
The Senior Network Engineer will own the performance, reliability, and scalability of Halter's wireless IoT network, which connects cattle collars to the cloud. This hands-on role involves designing network architecture, managing tower infrastructure, and ensuring robust data flow across rural environments.
