The role will involve contributing to the integration of production RAN software with PHY, channel, UE, traffic, and network models, and supporting the development of simulation capabilities for LTE, 5G NR, and 2G. This is a great opportunity to gain hands-on experience in RAN systems, simulation, and AI/ML within a highly technical environment.\nWhat will you do:\nContribute to the development of a modular, multi-RAT RAN digital twin covering LTE and 5G NR.\n\nDevelop and integrate production software components with simulation and analysis tooling using stable and maintainable interfaces.\n\nWork with software and system teams to model communication-system behavior, including traffic, mobility, scheduling, interference, and performance KPIs.\n\nSupport the extension of existing LTE simulation capabilities and reusable components for additional radio technologies.\n\nDevelop software components and tools in C/C++ and Python for simulation, automation, data processing, and analysis.\n\nSupport the development and evaluation of AI/ML-based capabilities for communication systems and network optimization.\n\nBuild datasets, experiment pipelines, and automated analysis tools to evaluate system behavior and algorithm performance.\n\nCreate reproducible tests and experiments across software builds and algorithm versions using defined scenarios, configurations, and KPIs.\n\nSupport simulation verification and validation activities, including comparison with lab results and analysis of model behavior.\n\nBuild automated unit, component, end-to-end, regression, and performance tests and integrate them into CI/CD workflows.\nImprove simulation speed, usability, observability, and automation so engineering teams can run repeatable experiments independently.\n\nDebug issues across C/C++, Python, MATLAB, system software, configuration, and reference measurements.\n\nDocument assumptions, supported scenarios, limitations, and experiment results in a clear and structured way.\n\nWork closely with RAN, PHY, system, AI/ML, automation, and validation teams to turn engineering questions into measurable experiments.\n\nWhat you bring:\nB.Sc. in Electrical Engineering or an M.Sc. in a relevant field.\n\nAt least 2 years of hands-on software development experience in communication systems or a related telecom environment.\n\nStrong software development skills in C or C++ and Python.\n\nGood understanding of communication systems and the ability to learn new technologies and system concepts quickly.\n\nExperience working in Linux development environments with Git, automated testing, and modern software development practices.\n\nStrong analytical and problem-solving skills, with the ability to investigate complex technical issues independently.\n\nGood communication skills and the ability to work effectively with software, system, algorithms, and validation teams.\n\nSimulation experience is not required; candidates with strong software and communication-system backgrounds are encouraged to apply.\n\nNice to have:\nExperience with simulation environments, system-level modelling, or hardware-in-the-loop testing.\n\nKnowledge of LTE and/or 5G NR, RAN, modem/PHY, or wireless communication systems.\n\nExperience with MATLAB and communication-system simulation or analysis tools.\n\nHands-on experience with scientific computing and data analysis using NumPy, SciPy, pandas, or similar tools.\n\nExposure to AI/ML, time-series analysis, signal processing, or network optimization.\n\nFamiliarity with PyTorch, TensorFlow, Hugging Face, or other machine-learning frameworks.\n\nKnowledge of digital communications and signal processing concepts.\n\nExperience with automated testing, containers, CI/CD, or cloud development environments.\n\nFamiliarity with SDR, radio test equipment, lab automation, or field-log analysis.","description_format":"text","description_chars":3930,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Israel","iso":"IL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Mobile Networks","Network Equipment"],"lifecycle":[{"event":"open","at":"2026-09-14T12:08:01Z"}],"visa":[],"liveness":{"score":25,"band":"fade","label":"Fading","p_open":1,"p_active":0.561,"p_room":0.44,"age_days":53,"expected_fill_days":50,"reasons":["conf:2","stale_co","velocity","win:tail","crowd:junior"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/parallel-wireless-ran-digital-twin-engineer","json_url":"https://alion.io/job/parallel-wireless-ran-digital-twin-engineer.json","meta":{"generated_at":"2026-11-07T11:18:18Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":11287,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4814},"rest":"https://alion.io/mcp/rest/get_company?id=4814"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fparallel-wireless-ran-digital-twin-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fparallel-wireless-ran-digital-twin-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fparallel-wireless-ran-digital-twin-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/parallel-wireless-ran-digital-twin-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fparallel-wireless-ran-digital-twin-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":902367}},{"tool":"search_jobs","arguments":{"company":"parallelwireless.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":902367},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
