(Senior) Full Stack Engineer (m/w/d)

Permanent employee, Full-time · Hybrid - Munich, Berlin or Sofia (Bulgaria)

Your mission

Tired from all the AI buzz and hype but excited to cut to the chase and work with latest AI models to bring actual value to customers and build end to end AI products? Then you fit right in!

We are a family-owned scale-up based in Munich, with over 400 employees across 5 locations in Europe - and more to come. Our innovative platform is already giving thousands of people worldwide access to a new, flexible and self-determined work environment while providing first-class customer service experiences.

We are shipping AI features since way before the age of LLMs and over the past years built up a team of exceptional AI Engineers (with strong research backgrounds in NLP, Speech and CV). Now we are ready to go the next step and build up an independent unit that will own and develop AI features and products end to end. Pretty much like a startup within a scaleup. For this we are looking for a stellar (Senior) Full-Stack Engineer who wants to build AI powered products that bring real value and users love.

Join us on this journey – in our offices in Munich, Berlin or Sofia (Bulgaria).

• Productionize AI Systems: You will develop not only individual features and modules but also entire microservices from the ground up, working with the latest AI technologies. Your ability to integrate both in-house and third-party AI models into scalable, robust services will be central to your role.
• Creative Freedom: You will have the freedom to propose and implement your ideas, collaborating with the team to define the architecture, select technologies, and shape development processes. Your vision will directly influence the technical direction of the product, ensuring its long-term success.
• End-to-End Ownership: Your responsibilities will span the full development lifecycle, from creating minimum viable products (MVPs) and pilot systems to deploying and maintaining large-scale production systems. These systems will process thousands of calls daily, requiring a focus on both performance and reliability.
• Solve Real Problems: You will work closely with a variety of stakeholders, including product managers, AI specialists, and other engineering teams. Your ability to translate business needs into technical solutions will be critical in ensuring successful outcomes across a wide range of projects.

Your profile

• Full Stack Experience: You have several years of experience writing production backend code in Python and frontend code in TypeScript. You have experience working with frameworks in the frontend (e.g. React or Vue) and backend (FastAPI, Flask or Django) but are not dependent on them. We mostly use Python 3.11 with type hints, and pre-commit hooks to ensure consistency
• Clean Code: You write clean, well-documented and easy to understand code but know when to be pragmatic to ship features efficiently
• Tooling: You're skilled with Docker and proficient in working with git and CI/CD pipelines. Ideally you know your way around Linux systems, ensuring reliable development and deployment
• Ownership & Monitoring: You embrace a "you build it you run it” attitude and make sure the systems that you develop are properly monitored (Prometheus and Grafana are no strangers to you)
• Fast Paced Development: You thrive in a fast-paced environment, turning high-level requirements into actionable tasks, and you actively collaborate with colleagues across departments

Why us?

• Opportunity: From day one, you’ll have the chance to shape new AI porducts in a fast-growing and profitable startup, leaving your mark and making a real impact
• Role: You will build your own area of responsibility and have a lot of freedom and ownership with quick decision cycles
• Innovation: Join an exciting environment that’s disrupting an established and slow-moving market. We support you with a results-oriented, motivated team and enable you to work with cutting-edge AI technology
• Team: Collaborate closely with an experienced founding team and strong management that values open discussion and mutual learning
• Impact: Together, we’re addressing the global trends of the Future of Work, Sustainability, and the Sharing Economy, working to create a better world
• Values: We see ourselves as a close-knit startup family that lives by the values of courage, authenticity, and sustainability. Show us how boldly you can take on this challenge and celebrate lasting success with us

About us

You made my day
...become a daymaker! Take advantage of the opportunity to help us revolutionise the contact centre industry...

We are a game changer - innovative, contemporary and different. A company where it's fun to be a customer, a talent but also an employee. At our Munich location, we develop forward-looking solutions for the contact center industry. In Sofia we implement our products for our customers.
Traditional contact centres often work according to the same principle: Open-plan offices and fixed working hours, a situation which is also associated with inflexibility and low pay for employees. All of this also leads to lack of motivation on the part of the employees and high costs for customers.

Yoummday takes a completely different approach. Since we were founded in 2016, we committed ourselves to fair and reliable remuneration as well as tasks that motivate our independent talents. All of this frees our customers from inflexibility and high costs.

We have revolutionized the contact center industry. Join the revolution. Become a daymaker.
