We are on the lookout for an experienced and ambitious Staff Frontend Software Engineer. In this role, you will use your skills and knowledge to help us set technical direction and develop our modern web UI application effectively. We are looking for a self-driven and proactive specialist who has worked on bigger frontend systems and is able to use this experience to influence development.

At Neptune, we have a quite ambitious goal of becoming an MLOps standard for data scientists worldwide. Our platform is a metadata repository built for research and production teams that run multiple ML experiments. Don't worry, you don't need to have ML skills. Our customers handle that part. 

We design Neptune to be extensible, flexible, and lightweight to ensure it fits any workflow and keeps up with this fast-paced field. Some of the things we do are pretty run-of-the-mill engineering work (REST, SQL, NoSQL + TypeScript, React), but often, we stumble upon a bigger challenge! After all, how many companies have implemented a custom scalable time-series storage moving data between various underlying storages, with the possibility to view and filter all of this in the UI in real-time?


Our tech stack:

  • JavaScript / TypeScript
  • React (+ Redux)
  • backend in Java (+ Spring), Scala, Kubernetes, Helm, containerization
  • Google Cloud



In this role you will be:

  • leading building larger, strategic features of the web UI application that is:
    • Scalable: we aim to be the standard for data scientists and ML engineers around the world – there are quite a few of them;
    • Portable: we offer both SaaS and on-prem installations. There are times when we need to be very lightweight;
    • Flexible: Machine Learning is a very fast-paced field; we often need to adapt;
  • cooperating with other Frontend Software Engineers helping them move forward when needed,
  • actively working with others at Neptune – helping to design new features,
  • defining our web UI application’s architecture,
  • driving the agenda – actively setting priorities of technical initiatives, frequently by example implementing more complex ones (this is a hands-on role).


Our expectations:

  • You have 10+ years of experience in Software Development of frontend applications.
  • You are proficient in JavaScript and TypeScript (hands-on role).
  • You have solid working experience with modern JS frameworks, React preferably.
  • You perform an excellent code review.
  • You are proactive – you can influence, discuss, research, and decide without supervision.
  • You’re always hungry for more knowledge – learning new things is natural for you; you do it constantly.
  • Knowledge of Machine Learning concepts would be awesome – but is not a must.


We offer:

  • Flexibility: 100% remote work with an office in Warsaw available and flexible working hours;
  • Share in our success: Participate in the Employee Stock Option Plan and be part of our growth journey;
  • Time off: 20 paid service-free days per year;
  • Ownership and impact: Space to take action, bring your ideas to life, and make a real impact;
  • Perks: Co-financing of private medical care and Multisport card, regular team building events, and free lunch when you’re at the office.
