Join our Team

About this opportunity

We are now looking for an engaged Junior Developer to join our team based in Poland. The team will work on how to prepare for the development of a powerful UE Simulator meeting the needs of 5G. The Simulation Services (SIMS) unit is responsible for providing Simulators to product development within Business Area Networks. These Simulators are used in product verification instead of real mobile phones and real core networks.

What you will do

  • Be part of an agile team that contributes to development of a UE Simulator.
  • Take part in configuring and testing our Simulators on the underlying hardware, making sure they behave correctly and reliably.
  • Work in an exciting technical area, supporting Ericsson internal users with an important product for 5G.
  • Get the opportunity to work with everything needed in a team: analysis, system design, pre-development and implementation in small increments, ensuring short feedback loops.

You will bring

  • Software engineering skills with the ability to write high-quality code (must have: Python; nice to have: C/C++ and Java)
  • Familiarity with the standards and protocols used in LTE or 5G networks.
  • Knowledge of RF propagation, modulation schemes and signal processing.
  • Knowledge of embedded systems and how software interacts with hardware components, ideally with hands-on experience configuring and testing software on hardware.
  • Knowledge of multi-core / multithreading processor programming and parallel processing, to simulate multiple data link connections efficiently.
  • Competence in Linux
  • Readiness to explore new opportunities, and to continuously learn and improve together with the team, with a genuine enjoyment of coding.
  • MSc or BSc level in Telecommunications, Electronics or Computer Science
  • Excellent speaking and writing skills in English.

Nice to have

  • Given our current Platform Engineering activities, including an ongoing migration to GitLab, a more DevOps-oriented profile is a strong plus.
  • Experience with the following will be valued:
  • Hands-on experience designing, building and maintaining CI/CD pipelines.
  • Solid knowledge of Git and GitLab, ideally in a CI/CD context.
  • Experience with Jenkins or another CI/CD pipeline orchestrator.
  • Familiarity with event-driven CI/CD architectures.

We work in a hybrid model, minimum 3 days from the office.

What we offer

  • Annual bonus depending on the achievement of the company's goals and results.
  • Possibility to take advantage of the reduction of tax-deductible costs for creative work.
  • Financial awards and distinctions.
  • Private medical care for the employee and their family (Medicover).
  • Life insurance.
  • Mental Help Line.
  • Cafeteria system on the Pluxee platform: co-financing of MultiSport or OK System card, lunch cards, and others.
  • Sports and integration activities (e.g. football, yoga, sailing team, climbing club).
  • Company support (loans and grants).
  • Possibility to participate in 3G / 4G / 5G / 6G technology projects.
  • Opportunity to participate in technical and interpersonal training conducted by international trainers.
  • Access to recognized learning platforms (Pluralsight, Skillsoft, Coursera).
  • Opportunity to work in an international environment, also outside Poland.
