Senior Lead Software Engineer - LLM Ops Platform in Glasgow

Requirements

• We have hands-on experience with system design, application development, testing, and operational stability in production environments.
• We have advanced proficiency in Python for building production-grade services and tooling.
• We have proficiency with automation and continuous delivery methods.
• We have hands-on experience with cloud infrastructure platforms and infrastructure-as-code tooling for delivery and lifecycle management.
• We have a strong understanding of site reliability engineering practices, including incident management, root-cause analysis, runbooks, and reliability patterns.
• We have practical knowledge of observability and instrumentation across metrics, logs, and traces.
• We have hands-on experience with Kubernetes and container-based orchestration platforms, including managed cloud variants.
• We have experience hosting and serving large language models on cloud-based infrastructure and local GPU environments.
• We have knowledge of large language model reliability and risk considerations, including latency and throughput trade-offs, model versioning, prompt and response logging, and safe rollout patterns.
• We have hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment, with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.
• We understand responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs and outputs, and adherence to resiliency and security expectations.
• We have the ability to guide peers on safe and effective usage within team practices.

Responsibilities

• We design, develop, troubleshoot, and deliver secure, high-quality production software and services for AI infrastructure.
• We build backend services and APIs that enable reliable operation of AI infrastructure in production environments.
• We operate and scale large language model serving infrastructure, including model hosting, request routing, continuous batching, and cache optimization.
• We deploy, host, and lifecycle-manage open-source and proprietary large language models on cloud-based container orchestration platforms and on-premises GPU clusters using reproducible infrastructure as code and continuous delivery pipelines.
• We implement observability across logs, metrics, and traces with dashboards and actionable alerting for large language model and GPU workloads.
• We tune GPU and accelerator capacity, autoscaling, and cost efficiency for large language model inference workloads using performance optimization techniques such as quantization, parallelism, and speculative decoding.
• We lead reliability engineering for large language model endpoints through capacity planning, load and soak testing, safe rollouts, failover, and incident response for outages and model-quality regressions.
• We participate in on-call rotations, lead incident triage and mitigation, and produce clear post-incident root-cause analyses and follow-up actions.
• We identify recurring operational issues and automate remediation to improve platform stability and developer experience.
• We build and maintain multi-agent systems with strong orchestration, including planning, coordination, tool-calling, state and memory management, and workflow control where appropriate.
• We drive team adoption of enterprise-authorized AI-assisted engineering practices to improve code quality, delivery speed, and operational outcomes, while establishing consistent validation standards and promoting reuse of effective patterns across the team.
