The platform is primarily built in Python, exposing APIs and a front-end to support ML practitioners across the company. As an engineer in this team, you'll work across infrastructure and software boundaries, driving the platform's evolution with a focus on usability, scalability, and reliability.


What You’ll Do

  • Design and build scalable backend services in Python using frameworks like FastAPI and SQLAlchemy
  • Implement DevOps practices: CI/CD pipelines, automated testing, and Infrastructure as Code
  • Contribute to the design, deployment, and management of cloud-native infrastructure (in GCP)
  • Work with Kubernetes, containers, and orchestration tools to deliver a robust ML platform
  • Collaborate closely with ML engineers and researchers to understand their needs and translate them into usable tools and services
  • Participate in code reviews, system design discussions, and knowledge sharing
  • Help evolve and shape the future of King’s ML platform

Must-Have Skills

  • Strong Python engineering skills with experience designing and maintaining APIs and backend services
  • Hands-on experience with DevOps practices and tools (e.g. CI/CD, monitoring,
  • observability)
  • Experience with Kubernetes and containerized workloads
  • Familiarity with cloud infrastructure, preferably GCP
  • Experience with frameworks like FastAPI, SQLAlchemy, or similar

Nice-to-Have Skills

  • Experience with MLOps and machine learning pipelines
  • Familiarity with tools like Terraform, Crossplane, Argo CD, Argo Workflows, and Dex
  • Exposure to GCP services such as GKE, Dataproc, or Vertex AI
  • Experience with MLFlow or other model tracking systems
  • Some familiarity with frontend development (e.g. React and TypeScript) is a plus

Who You Are

  • You’re a self-starter with a curious mindset, not afraid to explore unfamiliar territory. You’re eager to learn, ask questions, and share your insights. You value collaboration, enjoy constructive feedback, and strive to raise the bar for engineering quality in everything you do.


Why Join Us?

  • At King, you’ll help shape the future of ML at scale, working in a team that values engineering excellence, autonomy, and continuous learning. You’ll be part of a supportive environment where infrastructure meets software, and where your contributions directly empower ML innovation across the company
