Requirements

  • 7+ years of professional software engineering experience with a proven track record of building and operating large-scale distributed systems.
  • Strong programming experience with Golang, or the ability and willingness to quickly become proficient in the language.
  • Deep experience with Kubernetes and container orchestration systems, including real-world operation of production environments.
  • Strong understanding of distributed systems concepts such as consistency, availability trade-offs, queueing, backpressure, retries, idempotency, and multi-tenancy.
  • Experience designing and operating high-throughput, low-latency services with a strong focus on performance optimization and reliability.
  • Proven ability to take ownership of complex technical challenges, lead design discussions, unblock teams, and deliver impactful solutions.
  • Strong software engineering fundamentals with the ability to write reliable, maintainable code and investigate complex technical problems.
  • Collaborative mindset with excellent communication skills and the ability to work effectively across engineering and business teams.
  • Experience with serverless platforms or function-as-a-service technologies such as Knative, AWS Lambda, GCP Cloud Run, Cloudflare Workers, or similar solutions is a strong advantage.
  • Familiarity with GPU scheduling technologies, including Kubernetes device plugins, MIG, MPS, time-slicing, or NVIDIA GPU Operator, is highly desirable.
  • Experience with ML inference technologies such as vLLM, TensorRT-LLM, Triton Inference Server, SGLang, or similar platforms is a plus.
  • Knowledge of runtime optimization techniques including cold-start reduction, image streaming, checkpoint/restore, or sandboxing technologies is beneficial.
  • Experience developing Kubernetes operators using Go and frameworks such as controller-runtime or kubebuilder is advantageous.
  • Contributions to open-source projects related to serverless infrastructure, scheduling, or AI inference are a plus.

Responsibilities

  • 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.
