Senior Software Engineer (Serverless) - United Kingdom
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer (Serverless) based in the United Kingdom.
This role offers the opportunity to build the next generation of AI cloud infrastructure powering advanced machine learning workloads worldwide. You will work on a high-impact serverless platform designed to help developers deploy and scale AI applications without managing complex infrastructure. As a senior engineer, you will take ownership of critical distributed systems challenges, from GPU scheduling and runtime performance to customer-facing APIs and platform reliability. Working in a highly technical environment, you will influence architecture decisions, mentor engineers, and help define engineering standards. This position is ideal for an experienced software engineer passionate about large-scale systems, cloud technologies, and solving complex infrastructure challenges at the forefront of AI innovation.
Accountabilities
- Design, develop, and maintain core components of a GPU-native serverless AI platform, including control planes, schedulers, runtimes, autoscaling systems, and customer-facing APIs.
- Solve complex engineering challenges related to cold-start optimization, GPU scheduling, multi-tenant isolation, fair resource allocation, request routing, and platform scalability.
- Own technical architecture decisions for key platform areas by creating design documents, evaluating solutions, and aligning engineering teams around effective approaches.
- Establish and maintain high engineering standards through code reviews, design reviews, technical guidance, and active collaboration with team members.
- Operate services with an SRE mindset by defining reliability objectives, improving observability, supporting incident response, and driving continuous platform improvements.
- Collaborate directly with customers on architecture discussions, performance optimization, and complex production issues requiring deep technical expertise.
- Partner with product, infrastructure, and go-to-market teams to translate customer needs into scalable technical roadmaps.
- Contribute to improving platform performance, reliability, and developer experience through innovative engineering solutions.
- Support knowledge sharing and technical mentorship to help raise the overall engineering capability of the team.
