Document interfaces, scaling, rounding, saturation, and other assumptions needed to compare implementations.\nContribute to SystemC transaction-level modeling (TLM) and high-level synthesis (HLS) development, including synthesizable implementations, with guidance from engineers experienced in these flows.\nSupport pre-silicon verification and new-chip bring-up by running regressions, comparing model, firmware, and hardware results, investigating discrepancies, and documenting fixes with ASIC, verification, and software engineers.\nWhat you bring to this role:\nDemonstrated DSP and digital-communications fundamentals, including sampling, filtering, modulation, OFDM, synchronization, channel estimation, and error-correction concepts. Evidence may come from academic, research, personal, or professional projects.\nAbility to implement and debug numerical algorithms in C/C++, and to use Python or MATLAB for simulation, analysis, and test automation.\nWorking knowledge of wireless PHY processing and the ability to translate technical specifications into implementation and test cases; familiarity with the basic structure of a 5G NR PHY.\nUnderstanding of fixed-point arithmetic, quantization, overflow, and numerical precision, with the ability to compare an implementation against a reference model.\nUnderstanding of embedded software constraints, including execution time, memory use, and hardware/software interfaces, supported by practical implementation or debugging work.\nAbility to build reproducible tests, use version control, document technical assumptions and results, and explain discrepancies during code and design reviews.\nBonus points for the following:\nExperience with SystemC TLM, or with HLS tools to develop and verify synthesizable C/C++ or SystemC implementations.\nExperience with 5G NR or NTN algorithms and specifications, satellite channel modeling, or compensation for Doppler and timing effects.\nExperience with FPGA/ASIC verification, emulation, SDR platforms, chip bring-up, or laboratory validation of communication systems.\nExperience with 5G NR MAC, PHY/MAC interfaces, scheduling interactions, or HARQ procedures.\nExperience implementing and optimizing algorithms on vector DSPs, including SIMD intrinsics, vectorization, and efficient memory access.\nExperience with low-power ASIC or firmware design, including reducing computation and data movement, managing idle states, or measuring power consumption.\nAdditional Requirements\nThis is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.","description_format":"text","description_chars":3374,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-25T02:21:40Z"},{"event":"reopen","at":"2026-10-14T07:11:13Z"}],"visa":[],"liveness":{"score":75,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.837,"p_room":0.9,"age_days":27,"expected_fill_days":52,"reasons":["conf:2","velocity","win:mid","comp:brand"],"computed_at":"2026-10-22T06:10:10Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/espace-real-estate-dsp-sw-engineer","json_url":"https://alion.io/job/espace-real-estate-dsp-sw-engineer.json","meta":{"generated_at":"2026-10-22T07:06:36Z","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":2526,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":2438005},"rest":"https://alion.io/mcp/rest/get_company?id=2438005"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fespace-real-estate-dsp-sw-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%2Fespace-real-estate-dsp-sw-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%2Fespace-real-estate-dsp-sw-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/espace-real-estate-dsp-sw-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fespace-real-estate-dsp-sw-engineer"}]}
