Why is Ericsson a great place to work?

Ericsson enables communications service providers to capture the full value of connectivity. The company’s portfolio spans Networks, Digital Services, Managed Services, and Emerging Business and is designed to help our customers go digital, increase efficiency, find new revenue streams, and create new user experiences. Ericsson’s investments in innovation have delivered the benefits of telephony and mobile broadband to billions of people around the world ensuring our solutions – and our customers – are at the forefront of innovation.   We support networks that connect more than 2.5 billion subscribers. With over 100,000 employees and customers in 180 countries, we combine global scale with technology and service leadership.  40 percent of the world’s mobile traffic is carried over an Ericsson network.  And, our Technology for Good and Connect to Learn programs include creating technology that makes it easier to save lives, feed societies, bring technology to emerging markets and connectivity to remote areas, and grow businesses and prosperity.


At Ericsson, we give our employees the freedom to think big and navigate their career, on a global scale.  We create technology that helps others, from helping people enjoy their favourite content to helping people recover from natural disasters by enabling better communications between rescue workers. Your ideas and innovations can turn into achievements that impact society and change the world, creating new connections, new possibilities, and new capabilities.  We find that Ericsson is at its best when we bring together the diverse skills of our people. Working across business areas, across cultures, across geographical borders, across technical disciplines. More often than not, across ground-breaking solutions. Next generation technology can be staggeringly complex. But the simpler it is to use; the more people benefit from it. Join us and help build technology that makes it simple to connect with information, business, societies, and each other.



Radio SW strives to be the most competitive Radio Network R&D unit in the industry. We work in an agile set-up to develop and maintain competitive, high-quality Radio products which give our customer solutions securing future growth.


Radio SW is part of the Product Development Unit (PDU) Radio within Development Unit Networks (DNEW) in Business Area Networks (BNEW). We are based in Kista, Stockholm. We also have a close corporation with development of PDU Radio products in Ottawa, Beijing, Nanjing, Chengdu, Lund and Zagreb.


Radio SW provides the possibility to work with the latest technology within telecommunication development. We can offer a rich number of opportunities in an everyday learning, creative and challenging atmosphere.


A radio is normally built with Application Specific Integrated Circuits (e.g. ASICs). The primary reason for this is to achieve the performance required for resource intensive algorithms and functional blocks. In an ASIC architecture each functional block must be precisely defined, including its functionality, input/output pins and signals, as well as the performance requirement in terms of clock cycles.

A Software Defined Radio is a radio where parts of the ASIC functionality has been made programmable using software. This is typically non-generic, performance optimized software running on dedicated hardware that together with accelerators provide the functionality required. This software executes in an environment with limited resources and challenging real-time performance requirements.


This position is intended to drive the software in our programmable solutions and to provide support with the necessary craftmanship. This includes defining product architecture, characteristics requirements and participating in product studies.



  • Understand external and internal research, industry trends, competitor information and use this intelligence to innovate and propose technology leading solutions for our radio products
  • Secure that innovations are protected by patents
  • Define the architecture of the software in a Software Defined Radio to secure that the solution is flexible, easily deployed and can be re-used between products
  • Define requirements on the dimensioning of the hardware to achieve requested performance and flexibility and allow for future software upgrades
  • Accountable for functionality partitioning between the software application and the programmable parts of the Software Defined Radio
  • Create a methodology to analyze the value of product flexibility vs complete hardening. This includes looking at re-use in product variants and the life cycle of the product. This should be used to support product solution decisions
  • Propose and participate in pre-development activities to prove new concepts within the Software Defined Radio
  • Coach and act as a mentor in SW craftmanship



  • Education: MSc in engineering or similar
  • Min 10 years of relevant experience
  • Domain experience: ASICs, DSPs, realtime embedded SW close to HW, SW architecture
  • Experience in technical leadership for soft- and/or hardware development teams
  • Proficiency in C/C++
  • Quality and efficiency minded, analytical thinking
  • Good communication in English
  • Creative, proactive, with passion to win.
  • Familiar with radio/digital HW design is a strong plus
