Wireless Software Engineer - Finland - Linnanmaa District, Finland
Originally posted 21 September 2026 by the employer — open 0 days.
About the role
This role involves designing, implementing, and evolving test, emulation, and validation solutions for the wireless ecosystem, spanning device, chipset, network infrastructure, and Open RAN. You will translate 3GPP specifications into robust software capabilities to validate conformance, interoperability, and performance across the RAN lifecycle.
What you'll do
- Design and implement software capabilities aligned to 3GPP LTE/NR (e.g., RRC, PDCP/RLC/MAC, PHY interactions, procedures, state machines, timers, KPI/measurement semantics).
- Convert evolving requirements (3GPP releases, operator acceptance needs, O-RAN priorities) into clear software designs, test workflows, and reusable components.
- Build and maintain automation and tooling for protocol conformance, interoperability, and performance validation for RAN-facing scenarios.
- Collaborate with cross-functional experts to reproduce field issues, debug complex behaviors, and deliver fixes with strong root-cause discipline.
- Create high-signal artifacts: design docs, test plans, trace/pcap interpretations, and technical notes.
- Contribute to solution evolution for modern RAN architectures including Open RAN / O-RAN interfaces and multi-vendor environments.
What you'll need
- Hands-on expertise in 3GPP LTE/NR with a clear RAN focus (e.g., L1/L2/L3 procedures, scheduling concepts, mobility, bearers, signaling flows, performance metrics).
- Professional software engineering experience (typically 8+ years).
- Strong coding skills in C/C++ and/or modern Python for automation/tooling.
- Comfortable in Linux development environments.
- Proven ability to debug distributed/real-time systems: logs, traces, protocol analyzers, KPIs, timing, performance bottlenecks.
- Clear technical communication in English (written and verbal), including turning complex spec-driven topics into implementable requirements.
Nice to have
- Experience with RAN product development (gNB/eNB), RAN performance optimization, or feature verification in complex system environments.
- Familiarity with O-RAN architecture/interfaces (O-RU/O-DU/O-CU, fronthaul, RIC concepts) and multi-vendor integration challenges.
- Experience with CI/CD, test frameworks, containers, and/or cloud-based deployment environments.
- Prior exposure to standards work (3GPP RAN1/2/4/5) or strong experience implementing features directly from evolving specs.
Skills: 3GPP LTE/NR, RAN, C/C++, Linux, Open RAN
