Lead Machine Learning Engineer (m/f/d)

Permanent contract
Berlin, Bangalore, Remote
Previous experience in being a technical lead

Hello ๐Ÿ‘‹ I am Servesh, Co-Founder and CTO of Kayzen, and I am now looking for a Lead ML Engineer who will be reporting directly to me, managing our whole ML Team and taking full ownership of our ML topics ๐Ÿ™Œ

But wait, you have not heard of Kayzen before? ๐Ÿ˜ƒ 

In short, Kayzen is a B2B SaaS platform that allows companies to reach users with video and rich media ads while they use mobile apps. 

We are a 65-people international team, working flexibly across 8 different countries:



How would I describe the engineering challenges in Kayzen?

We have to deal with >100bn ad requests from 1bn+ unique users worldwide on a daily basis. 

This implies we areโ€ฆโ€ฆ

  • Handling ~2 Million Req/sec in sub-millisecond latency

  • Handing and managing ~Petabytes of data

  • Managing distributed systems deployed across multiple data centres

  • Optimizing JVM and Linux kernel for optimal performance

  • ๐Ÿ“š(If you would like to know more about our engineering, read this, and this as well ๐Ÿ˜‰)๐Ÿ“š


How would I describe the culture of Kayzen Engineering?

  • Collaboration ๐Ÿค- Every workday we would have a stand-up for us to ask each other questions. โ€‹You will also have a buddy at the beginning of your tenure, making sure you will be truly embedded into the team.

  • Ownership ๐Ÿš€ -  โŒMicro-management is NEVER our styleโŒ

  • Positivity ๐Ÿ˜„ - We will eventually find our way around the hard technical challenge. Stay relaxed, and work smart โ€‹โ€‹ ๐Ÿ˜Œ

  • Curiosity ๐Ÿ’ญ- We think ahead. We ask โ€œWhyโ€. We challenge our assumptions.


Together with the ML Engineering Team, you will be hands-on with them intoโ€ฆ..

  • Defining solution architectures designs.

  • Applying state-of-the-art machine learning techniques to create insights and convert them into actions.

  • Developing code that is production-ready and producing our ML models in both bare-metal and the cloud environment.

  • Setting up and applying MLOps frameworks.

  • Reducing manual effort and developing configuration-driven frameworks.


Sounds like you? ๐Ÿ˜‰

  • Experience in leading teams and using agile methodologies in a fast-paced environment.

  • Know your way around relevant programming languages (SQL, Python, R, etc.), Machine Learning techniques (Neural Networks, Random Forest, etc.), Cloud computing (AWS, Azure or GCP) and ML frameworks (MLflow, PyTorch, Tensorflow, etc.).

  • Familiar with Git, command line, SQL & NoSQL, Spark, Docker and API frameworks

  • Excellent stakeholder management skills


โญThe north star of Kayzen ML (and how you could get us there)โญ

  • Challenge us and make Kayzen an ML-first organisation - Imagine different teams (Product, Design, Analytics, Business) can understand ML, be data literate and donโ€™t inhibit themselves with the thought of what can or cannot be achieved with traditional constraintsโ€ฆ..

  • Hence, apart from building and leading our ML Engineering Team, being our advocate for being an ML-first organisation is your important task as our ML leader.


All in all - Why Kayzen? 

  • We genuinely see encouraging ownership of your quality work, accelerating your career development, and keeping+hiring exceptional colleagues as the biggest perks (above everything else)

  • ๐Ÿ’ฐWe are already profitable. So you can expect stability from the company financially, and you can enjoy the thrill of working in a start-up environment at the same time.

  • Our work is driven by our own team, rather than external parties (e.g. Often start-up/scale-up companies can be heavily influenced by external parties, such as venture investors who are not deeply into the business.)

  • Transparency - Day-to-day work experience with the management team and regular business updates to the team

  • ๐Ÿ˜ƒOur Kayzenians - For instance, we did a global week of workation offsite in 2022. Check out how we were having fun here. Perhaps we will see you in the next offsite as well?๐ŸŒด 

Other benefits for every Kayzenian globally 

  • Competitive compensation package

  • Parent-friendly company culture

  • Remote-friendly company culture

  • $500 home-office-equipment budget

  • $1000 annual learning and development budget


Our team genuinely believes high-performance outcomes are achieved through hiring top talent and creating a productive and healthy work culture.

๐Ÿค— Hopefully the above excites you enough to apply ๐Ÿค—


 P.S. Not sure whether you should apply as you think you may not meet all the above criteria? 

  • No worries, just apply for the role first ๐Ÿ™‚ 

  • We encourage you to apply even if you meet only some of the points in the job description. 

  • Then, we could have a chat and see if you could be suitable for the role.
