Senior Backend Software Engineer (Java)

Company Description

🚀 SmartRecruiters is building an operating system for recruiting and is on a mission to connect people with jobs at scale. The company is growing very fast and recently hit the 1.5 billion dollar valuation. The system is used by over 4,000 companies, including LinkedIn, McDonald's, VISA, CD Projekt Red, Allegro, and many many more! 

🚀 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 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 work for the business” (yes, we are heavily influenced by this and that).

Job Description

• Collaborate with other teams

Qualifications:

• Proven experience in designing, developing, and operating distributed systems

• Experience in supporting end-to-end product lifecycle (from product discovery, solutioning, system design, implementation, production rollout, and optimization)
