The posting

About Juna AI

We bring cutting-edge AI to the physical world. We operate on the factory floor, which means that you will see your software run on real machines, in real industrial plants. If you want to build AI products that change how the world runs, you will love it here.

Recognised as a leading industrial AI company globally by Gartner and Forbes. Backed by Kleiner Perkins and Norrsken, the investors behind Google, Amazon and Anthropic. Our founders have led engineering teams of up to 2,500 people, launched more than 50 internet companies, and built apps used by over a 100 million people.

Life At Juna AI

We are a small team taking on a massive challenge. Heavy industry accounts for a huge share of global emissions and runs on workflows unchanged in decades. We are building the agents to change that.

We move fast, work face-to-face, and care about outcomes, not optics. This is not for everyone. If you want to work alone with predictable sprints, this will not fit. If you want to ship every day, raise the bar, and never stop learning, it will.

We are a team of people from different backgrounds and identities. We act like owners. We think full-stack. We co-design with our customers. We care for quality and design. We believe a job is done when it’s done well. We are optimists.

What you get

  • Close proximity to founders. Work face-to-face with founders who have done this before. You will learn faster here than anywhere else.
  • Real influence on strategy. As one of our first engineers, you will shape product direction. Best idea wins, regardless of seniority.
  • Low bureaucracy. Lean, autonomous teams. Decisions get made in hours, not weeks. Rapid experimentation is the default.
  • Career compounding. As we are a fast growing, seed-stage company, your scope and responsibility grow with the company.
  • Meaningful equity and competitive salary. You are one of the first to build this, and you share in the upside.

About The Role

As Product/Platform Engineer at Juna AI, you will work closely with our technical founder to build our core technology. This includes our data processing platform, our agent training and inference engine and beautiful customer facing applications.

We expect you to wear multiple hats, embracing a true full-stack mindset. We believe in quality at all levels, as well as the power of fast iterations and continuous refactoring to create a scalable and clean codebase as the foundation of our long term success.

If you are willing to stretch yourself from AI-, backend-, to frontend- engineering, if you enjoy building high quality, pragmatic code in short iterations, if you can push the boundaries of what is possible with technology, Juna is the right place for you.

What you will get to do

  • Building: Create clean, pragmatic, scalable code.
  • Product Ownership: Take the lead on product features. Combine high quality technical delivery with strong focus on delivering customer value.
  • Systems Design: Tackle complex technical challenges and design systems that can evolve from prototype to production.
  • ML Deployment: Work closely with our machine learning staff at a technical level to bring agent models to production.
  • Customer Integration: Deploy solutions within our industrial customers organizations, making a tangible difference in their operations.
  • Algorithm Development: Solve hard algorithmic problems that arise when interfacing ML with real-world physical systems.

About You

Personal Qualities

  • Pragmatic Problem-Solving: Analytical and pragmatic – able to navigate complex problems while keeping things simple
  • End-to-End Ownership: Comfortable owning features end-to-end, from design to deployment
  • Team Collaboration: Collaborative and communicative – able to work effectively across engineering, ML, and product

Tech Excellence

  • Full-Stack Experience: Strong engineering background with experience across the stack
  • Modern Languages: Fluent in modern web technologies, preferable Python stack.
  • Scalable Systems: Experience building and maintaining scalable, production-grade systems and APIs
  • Infrastructure Know-How: Familiar with containerization, CI/CD, cloud infrastructure, and DevOps best practices
  • Data & ML Bonus: Experience working on data processing pipelines, ML deployment, or real-time systems
  • Frontend Bonus: Familiarity with frontend frameworks (e.g. React) and an eye for clean UI/UX

Practicalities

  • Berlin-based, on-site. We work together in person.
  • Working language is English. Other languages are a plus, not a requirement.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
