Job description
This vacancy has now expired. Please see similar roles below...
Our engineering team solves one of the most important problems of the modern economy - connecting great people with great jobs. We believe this problem can only be solved with technology, and we developed a software platform that has supported over 100M job seekers to date (with 5M joining every month). We are looking for a backend engineer to help us build the next chapter of that vision. You may be located anywhere in Germany or Poland and work remotely or out of one of our hub offices.
We designed our R&D structure based on the empowered product teams model. It means our teams are responsible for business outcomes and have autonomy in solving problems in the way that “customers love yet works for the business” (yes, we are heavily influenced by this and that).
Our technology platform is a SaaS product hosted on AWS (and soon also GCP). Our system is composed of hundreds of independent services (each sitting on Docker, orchestrated by Kubernetes).
We build most of our services in Java, Javascript (Node.js), and Python. We have a strong CI/CD culture, and we currently run 40 production deployments per engineer per month.
What you’ll deliver:
Contribute to a full life-cycle of the product (including problem discovery, prototyping, design, implementation, and measuring adoption)
Build services with Java / Node.js (Express, Nest.js) on top of Kubernetes/AWS/GCP infrastructure
Build developer-friendly RESTful APIs
Design and connect to our persistence layer (PostgreSQL, ElasticSearch)
Collaborate with other experience and platform teams

We believe in promotion from within, so high performance can lead to upward mobility. Needless to say, we make sure you’re taken care of. Our inclusive office environment welcomes and respects all.
Experience in designing, developing, and operating distributed web-based systems
Experience in supporting end-to-end product lifecycle (from product discovery, solutioning, system design, implementation, production rollout, and optimization)
While not strictly required we see most of our Senior Engineers have 5+ years of professional experience.
Deep command of Java programming language
Hands-on experience with TDD, clean code and clean architecture principles, and effective code reviews.
Strong domain modeling skills - including refactoring existing domains.
Good understanding of persistence layer design
Good understanding of RESTful API design
Understanding of distributed systems design (design for failure, eventual consistency, asynchronous communication, circuit breaking, timeouts, etc.)
Ability to coach and mentor other engineers
Excellent collaboration and communication skills
Strong command of English language, both written and verbal
Experience in CI/CD would be a plus (running multiple deployments per day)
Familiarity with AWS/GCP, Kubernetes, and Docker would be a plus
