Machine Learning Engineer / MLOps

Zagreb, Croatia /Hybrid /Full-Time /Engineering

Ever wanted to work in an early-stage startup that where your decisions could shape the company's future? Or where your decisions will shape the design of a state-of-the-art AI product for image and video processing used by hundreds of thousands of people?

We are looking for a Machine Learning Engineer / MLOps who will be in charge of improving and maintaining our backend and ML infrastructure.

This is our current backend and ML infra stack:

  • AWS + DigitalOcean
  • Torchscript + Pytorch
  • TensorRT
  • Docker
  • Django v4

Mandatory requirements

  • 1+ years of experience with Python and essential development tools/technologies such as Git and Docker. It doesn't have to be formal on-the-job experience, it's important that you have actively been using the technology for minimum of 2 years.
  • Experience with the full ML model cycle: Research/Training ➝ Testing ➝ Deployment ➝ Monitoring
  • Experience with CI/CD pipelines
  • Minimum master’s degree (last year of university is also ok) in computer science, software engineering or related field.
  • Flexibility and a strong desire to learn. You will occasionally take on responsibilities that are not in the original definition of a ML engineer role (e.g. brainstorming product design, product testing, talking to clients...).
  • Ability to self-manage as you will be the most senior person in this role.
  • Tolerance for ambiguity. You're comfortable with making decisions where outcome is uncertain.
  • Proactivity ➝ you think how to improve stuff and come to other colleagues with concrete suggestions. Or even better, you try to improve something by yourself in an isolated test environment and present your findings to others.
  • Excellent communication skills.
    • Example 1: Good: you're stuck with a problem and can't seem to find the solution ➝ you ask other colleagues for help ASAP. Bad: You keep trying to solve the problem by yourself and waste hours or days to find the solution.
    • Example 2: Good: If you think something is not being done properly, you give specific arguments why that's not good and what would be a better alternative. Bad: You keep quiet even if you think something bad is going on / being decided.
  • Good knowledge of software engineering best practices such as unit testing, code reviews, design, and documentation.
  • Good English knowledge.
  • Being comfortable with using at least one the Linux based OS-es.

Nice to have (sorted by relevancy)

  • You have worked in a startup or similar fast-paced environment for at least 6 months.
  • You have worked on personal/public projects that are live in production and ready to be showcased.
  • Experience with Kubernetes
  • Experience with AWS or any other cloud platform
  • Experience with infrastructure as a code software (e.g. Terraform, Ansible...)
  • Experience with the ML stack: Pytorch, TensorRT,, Tensorflow...
  • You have worked in a company that developed a software product for the media and entertainment industry.

What you'll be doing (sorted by relevancy)

  • Build scalable backend and ML infrastructure
  • After the ML model is trained, your job would be to optimize it (reduce latency, increase throughput, reduce memory footprint...), deploy it in the production environment, and setup monitoring.
  • Build CI/CD pipelines
  • Occasionally research and train new ML models for various computer vision tasks like super-resolution, denoising, image generation...
  • You’ll be reviewing code and design docs, and giving feedback on product specs and mocks.
  • Manage individual projects priorities, deadlines and deliverables with your technical expertise.
  • Mentor and train other team members on design techniques, and coding standards.

What do we offer?

  • Base salary: €1,760 (13,260 HRK) - €3,200 (24,110 HRK) gross (bruto 1). The larger the base salary, the less equity we can offer, and vice versa.
  • Employee stock ownership plan - ESOP.
  • Monthly 1 on 1 meetings for exchanging feedback.
  • Financed further education (books, courses, conferences...). 📚
  • Annual performance bonuses.
  • Heavy involvement in strategic decisions that have an impact on the product direction and company development.
  • Rapid learning environment
  • Provided working laptop + external monitor.


  • Flexible working hours.
  • Flexible vacation days. 🌴
  • Work remotely and on-site (on-site is mandatory during the first few weeks for easier communication and acquaintance with existing processes and people). We prefer the hybrid way - e.g. 3 days office, 2 days remote.
  • Multisport card.
  • Unlimited high-quality coffee at the click of a button. ☕
  • The prettiest sunset view in the whole city. 😍
  • We are open to new perk ideas if they sound reasonable.
