Digital Signal Processing (DSP Engineer
Location
Herndon, VA | United States
Job description
iDirectGov's hubs, satellite routers and network management software address the growing complexity of deploying and managing global IP networks. iDirect Government’s specialized technology includes transmission security (TRANSEC), Communication Signal Interference Removal (CSIR™) anti-jam technology and Open Antenna Modem Interface Protocol ( OpenAMIP ). We bring innovation, integration and intelligence to satellite-based IP communications that government and military organizations trust. By providing quality certifications with the most bandwidth-efficient, scalable and highly secure platform, we have rapidly become the technology provider of choice for military and government-driven mission-critical applications.
We are seeking for a team player with solid technical skills to work with our team of smart, creative, and dedicated engineering team-members. This position is based out of our Herndon, VA location with the option of a remote work schedule.
This is a entry level cross-functional engineering position, supporting the development of our satellite communications equipment. Our products incorporate FPGAs and CPLDs from a variety of vendors including Xilinx and Altera/Intel. In this role, the engineer will be responsible for the creation, simulation, and validation of RTL based designs, including digital communications capabilities. In addition, the engineer will be expected to provide architectural insight to both hardware and software engineers and ensure designs can be successfully integrated into the larger system.
- Designing and testing DSP-based, high speed FPGA designs
- Designing and supporting top-level digital communication design and system simulations
- Translating requirements into FPGA/waveform architectures
- Implementing and documenting FPGA designs using HDL (System Verilog, VHDL, etc.)
- Supporting systems integration and Test Engineering to produce functional design
- Producing simulations of and designs for both channel improvement measures, such as spectral bandwidth efficiency, and user density improvement measures, such as interference mitigation/cancellation, multiuser detection, and phased array antenna techniques
- Designing the implementations for further advances in adaptive TDMA, SCPC return channels
- Designing and the implementation of anti-jam DSP techniques implemented in FPGA logic
- Writing internal and external facing documents about iDirect Government physical layer FPGA technology
- 2-3years of related experience
- FPGA design experience using Verilog, VHDL or System Verilog language targeting Xilinx/Altera FPGA’s
- Knowledge of DSP and digital communications. Understanding of time domain versus frequency domain analysis, filter structures, and modulation/coding algorithms. Ability to describe and architect trade-offs for resource-limited systems.
- Experience Matlab /Simulink or equivalent for development of DSP algorithms implemented in FPGA’s
- Ability to plan/perform analysis, studies/trade-offs in support of subsystem specification and hardware, FPGA and software design recommendations
- Experience in RF lab, including network setups (switches, cables, amplifiers and filters) and signal analysis (Spectrum Analyzers, Network Analyzers, signal generators, etc.)
Additional experience in the following areas is a plus:
- Experience with digital communications and control theory – stability and feedback control
- Extensive experience with both Altera and Xilinx design and verification tools
- Experience with Xilinx and Altera System-on-Chip devices: Xilinx Zynq-7000, Xilinx Zynq MPSoC , Altera SoC FPGA
- Background in RF chain design and considerations
- Background in anti-jam methodologies and design considerations
- Experience with C/C++, bash, Python programming, etc.
- Experience with Xilinx and/or Altera high level synthesis tools
- Experience in an Agile/Scrum environment
- Satellite Communication experience
Education: Bachelor's degree (BA/BS) in electrical engineering, computer engineering, or closely related field (must be from accredited college or university); MSCS/MSEE would be a plus
Clearance: Active DoD security clearance or ability to obtain a secret level DoD clearance.
Travel: 0-10%
