Greenwave information

What is a Greenwave?

Greenwave typically refers to an organization or initiative focused on sustainable and regenerative ocean farming, particularly the cultivation of seaweed and shellfish. The goal of Greenwave is to create environmentally friendly, low-impact forms of aquaculture that provide sustainable food sources, restore marine ecosystems, and combat climate change. Greenwave projects often involve training ocean farmers, developing new farming methods, and advocating for policies that support ocean health. By promoting these practices, Greenwave helps create jobs, support coastal communities, and improve the health of our oceans.

What are the key skills and qualifications needed to thrive as a Greenwave environmental technician, and why are they important?

To thrive as a Greenwave environmental technician, you need a background in environmental science, data collection, and marine biology, often supported by a relevant degree or certification. Familiarity with GIS software, water quality testing equipment, and data analysis tools is typically required. Strong problem-solving abilities, teamwork, and effective communication help technicians excel in fieldwork and engage with diverse stakeholders. These skills and qualifications are crucial for accurately monitoring ecosystems and contributing to sustainable environmental solutions.

What are some common challenges faced when working in the Greenwave project management team?

Professionals working on the Greenwave project management team often encounter challenges related to balancing multiple sustainability initiatives, coordinating with cross-functional teams, and ensuring regulatory compliance. The dynamic nature of environmental projects means priorities can shift rapidly, requiring strong adaptability and communication skills. Additionally, team members frequently collaborate with external partners and stakeholders, making effective relationship management and clear documentation essential for successful project delivery.

What is the difference between Greenwave vs Marine Technician?

Required CertificationsMarine certifications, safety trainingMarine certifications, safety training
Work EnvironmentOffshore, marine vessels, renewable energy sitesOffshore, marine vessels, repair facilities
Industry UsageRenewable energy, marine projectsMarine industry, ship maintenance
Common Search IntentGreenwave vs Marine TechnicianGreenwave vs Marine Technician

Greenwave and Marine Technicians both work in marine environments requiring similar certifications and safety training. Greenwave specialists focus on renewable energy projects like offshore wind farms, while Marine Technicians often handle ship repairs and maintenance. Both roles are essential in the marine industry, but Greenwave positions are more aligned with renewable energy sectors, whereas Marine Technicians serve broader maritime needs.

About the Role
GreenWave Radios is building the next generation of Cellular Infrastructure Radio solutions, and we're looking for a Staff DSP Systems Design Engineer to own end-to-end system architecture for our 5G NR and O-RAN product lines. You'll translate real-world RF and protocol requirements into silicon-level specs, working at the intersection of RF, baseband, and massive MIMO - all the way from architecture to lab validation. This is a hands-on, high-impact role at a company that ships.
What You'll Do
  • Define and own system-level architecture for cellular SoCs, including link budgets, system partitioning, mMIMO beamforming chain design, and performance trade-off analysis
  • Architect and specify O-RAN compliant subsystems - define split options (7.2x, 6, 8), fronthaul interface requirements, and RU/DU functional partitioning in coordination with protocol and firmware teams
  • Develop and maintain detailed system specifications covering RF front-end, baseband, clocking, power, and RF/digital interfaces, serving as the authoritative reference for IC design teams
  • Build and run system simulations (RF link, mMIMO beamforming gain, interference, EVM, sensitivity, dynamic range) to validate architecture decisions before tape-out
  • Lead lab bring-up and characterization of prototype hardware, including hands-on use of spectrum analyzers, signal generators, VNAs, oscilloscopes, and protocol analyzers to validate RF and system performance
  • Define test plans and acceptance criteria for system-level performance, and work closely with test engineers to implement automated measurement flows in the lab
  • Partner with RF, analog, digital, and firmware teams to resolve cross-domain issues discovered in simulation or lab - own the path from root cause to silicon fix
  • Drive system-level compliance verification against 3GPP 5G NR and O-RAN Alliance specifications, and represent GreenWave in standards and alliance working group discussions where applicable
  • Produce clear architecture documents, design review materials, and technical trade-off memos that inform product and executive decisions
  • Assist in mentoring junior systems engineers; establish best practices for system modeling, specification, and lab methodology
What You Bring
  • 8+ years of hands-on experience in wireless systems development (LTE, 5G NR)
  • PhD in Electrical Engineering required
  • Proficient in signal processing analysis/modeling skills with Matlab, Python or C/C++
  • Strong understanding of communication theory & signal processing related algorithms design (such as timing recovery, signal estimation and detection, MIMO signal estimation and detection, automatic gain control, channel estimation, equalization, coding theory, beamforming, etc.)
  • Familiar in 5G NR system architecture - PHY layer, numerology, beamforming, and massive MIMO (mMIMO) antenna system design
  • Experience with O-RAN architecture: functional split options, O-RU/O-DU/O-CU definitions, fronthaul (eCPRI/CPRI) specifications, and O-RAN Alliance WG4/WG7 compliance
  • Proven lab experience - comfortable operating and interpreting data from spectrum analyzers, signal generators, VNAs, oscilloscopes, and RF test equipment in a prototype bring-up environment
  • Hands-on experience with Cadence tools (Virtuoso, Spectre, or AWR Microwave Office) for schematic capture, simulation, or system-level modeling
  • Experience authoring system-level specifications and architecture documents that drive IC design decisions
  • Strong fundamentals in RF system analysis: noise figure, linearity (IIP3, P1dB), dynamic range, phase noise, spurious, and link budget methodology
  • Familiarity with 3GPP 5G NR standards testing and compliance methodology (TR 38.803, TS 38.104, etc.)
Nice to Have
  • Experience with MATLAB or Python for system-level simulation, mMIMO beamforming modeling, or automated test scripting
  • Exposure to mixed-signal or RFIC design in advanced CMOS nodes (28nm, 22nm, 16nm FD-SOI or FinFET)
  • Familiarity with O-RAN open-source platforms or test tools (e.g., OSC, OpenAirInterface, ORAN-SC) for integration and conformance testing
  • Familiarity with AI-assisted test data analysis and ML-based signal/power integrity prediction tools to catch issues earlier in the design cycle
  • Experience using Claude Code or similar AI coding assistants to accelerate design scripting, simulation automation, or documentation - familiarity with agentic AI tools for engineering workflows is a genuine differentiator
  • Experience applying AI to technical documentation workflows - LLM-assisted datasheet parsing, specification drafting, or design review summarization
  • General comfort adopting AI-augmented workflows to boost design productivity - this is a plus, not a requirement, for the right hands-on cellular systems expert
Compensation and Benefits
At InnoPhase, dba GreenWave Radios, our total rewards package includes both a competitive base salary and pre-IPO stock options. The anticipated base salary range for this position is $180,000 to $200,000 annually. Actual compensation will be determined based on several factors, including market conditions, interview performance, skills, qualifications, experience, education, and geographic location.
