Job requisition: JOB-0377

Engineering builds and runs TalentOS — the hiring platform this careers site is itself running on. Job search, the application flow, the recruiter console, and the services underneath all of it.
Build and run backend services from our Kraków engineering team — applications, interviews, offers and the queues behind them.
The platform is multi-tenant and the correctness bar is unusually high for a product of its size: an application that goes missing is somebody's career, not a support ticket. Traffic is spiky by nature — a campus placement season concentrates a year of applications into a fortnight — so capacity and queueing are ordinary design concerns rather than scaling exotica.
Day to day this role works with Node.js, PostgreSQL, API Design and Docker.
The same for every role, at every level — a haul truck driver and a staff engineer get the same cover.
Provident fund and gratuity as standard, group life and accident cover, and pay reviewed annually against the band for your level.
Family medical insurance including parents, an annual health check, and on-site occupational health at the mine and plant sites.
A yearly learning budget you choose how to spend, certification support, and sponsorship for the statutory tickets mining roles require.
Earned leave, casual and sick leave, public holidays by state, and parental leave for both parents.
Applying takes one form. You will get a Candidate ID immediately and can follow every stage from your dashboard.
None of these are required. They are the things that would help, and a strong application is regularly missing all of them.
Small teams that own a surface end to end, from the migration to what a candidate sees on a slow connection. Code review is expected to teach, not just approve. On-call exists and is compensated, and the rotation is built so nobody is woken twice in a week.
The individual contributor ladder runs to Principal and Distinguished without requiring anyone to become a manager. Moving into management is a lateral choice made deliberately, not a promotion you fall into.
Kraków hosts backend and data engineering for the European platform.
An established engineering city with a lower cost of living than Warsaw and the same access to the European team.
