Senior Software Engineer – API & ML Infrastructure

Job description


About Us
We’re a stealth-mode deep tech startup rethinking how AI models train, adapt, and scale. Our mission is to optimise large-scale AI systems — making them faster, smarter, greener, and cheaper. We are backed by leading VCs and already have commercial traction.

If you’re excited by infrastructure that powers the frontier of machine learning, we’d love to talk.

The Role
We’re looking for a Senior Software Engineer to lead development of a high-performance API platform that serves machine learning models at scale. You’ll take full ownership of the infra stack — from backend APIs to deployment and scaling. This role sits at the intersection of MLOps, cloud-native architecture, and distributed systems.

What You’ll Do
  • Build scalable APIs with FastAPI (or similar), Python, and modern web tooling
  • Design and maintain ML model serving infrastructure
  • Collaborate with ML engineers on training and deployment workflows
  • Own deployment: Kubernetes, Terraform, CI/CD pipelines
  • Drive best practices in system design, performance, and reliability
What We’re Looking For

  • Strong backend skills — Python, REST APIs, FastAPI
  • Proven experience scaling cloud-native systems (AWS, microservices, IaC)
  • Kubernetes + Terraform expertise in production environments
  • Solid understanding of ML deployment (e.g. PyTorch, TensorFlow, JAX)
Why Join?
  • Equity with serious upside and rapidly rising valuation — early-stage, high-impact
  • Work at the cutting edge of ML systems and optimisation
  • Autonomy and ownership from day one
  •  Fast growth path — help define both tech and culture
  •  Close-knit, no-ego team of engineers and researcher
