About the job

Title: Senior SATCOM Systems Engineer

At KBR, we deliver science, technology and engineering solutions to governments and companies around the world. KBR employs approximately 37,000 people worldwide with customers in more than 85 countries and operations in over 28 countries. KBR is proud to work with its customers across the globe to provide technology, value-added services, and long-term operations and maintenance services to ensure consistent delivery with predictable results.

Trinzic is the future independent company to be created through the planned spin-off of KBR's Mission Technology Solutions business, expected in January 2027. Our people work at the frontier of what is possible, delivering solutions in challenging environments and advancing some of the world's highest-priority national security and space missions.

Backed by decades of mission success, deep expertise, and trusted partnerships, Trinzic will launch as a global organization with more than 18,000 employees supporting customers around the world. Join us at a defining moment and help shape the future of a company built to tackle complex challenges and make a meaningful impact.

Candidates who join KBR's Mission Technology Solutions business before the spin-off will transition to Trinzic when the separation is complete and will not need to reapply for employment.

Summary:

The Senior Satellite Communications (SATCOM) Systems Engineer will support the architecture, analysis, integration, and technical oversight of advanced satellite communications systems. The role requires strong technical depth in RF engineering, digital communications, and modem development, with emphasis on physical layer performance and waveform implementation. The engineer will work across RF, IF, baseband, and networking layers to evaluate and develop modem and terminal architectures for military and commercial satellite communications systems.

Responsibilities:

Analysis of modulation and coding performance, multiple access techniques, waveform optimization, and integration of SoC/FPGA-based communications subsystems.

Analyze and define modem and RF subsystem architectures for SATCOM systems

Evaluate modulation and coding schemes (QPSK, 8PSK, APSK variants, LDPC, Turbo, etc.) under operational link conditions

Assess and support implementation of multiple access techniques

Develop and review link budgets, spectral efficiency analysis, and interference mitigation strategies

Support System-on-Chip (SoC) or FPGA-based modem implementations and hardware/software partitioning decisions

Define system and interface requirements across RF, IF, baseband, and Layer 2 interfaces

Support integration and test of modem and terminal subsystems in laboratory and field environments

Identify technical risks and performance trades across waveform, RF, and network layers.

Serve as subject matter expert (SME) for SATCOM systems and technologies.

Mentor junior engineers and support technical development of project teams.

Lead technical reviews including SRR, PDR, CDR, TRR, and customer readiness reviews.

Interface directly with customers, government stakeholders, vendors, and subcontractors.

Required Qualifications:

BS in Electrical Engineering, Physics, Applied Mathematics, or related field

8+ years of progressively responsible experience in communications system development

Demonstrated hands-on experience supporting modem, waveform, or RF subsystem design or integration

Experience supporting integration and system-level testing

Experience working in DoD or defense communications programs

Strong foundation in RF engineering principles including non-linear effects, phase noise, filtering, frequency planning, and interference analysis

Deep understanding of digital communications theory including modulation, coding, synchronization, and detection

Experience evaluating or implementing ModCod strategies and adaptive coding and modulation

Experience with multiple access schemes

Experience performing link budget analysis and system performance modeling

Experience with FPGA or SoC-based modem architectures

Experience with modeling/simulation tools such as MATLAB or equivalent

Ability to translate waveform and RF performance analysis into actionable system requirements

Active DoD SECRET clearance.

Desired Qualifications:

MS in Electrical Engineering (Communications, RF, or Signal Processing concentration preferred)

Experience with MILSATCOM (WGS, AEHF, MUOS) or Commercial SATCOM systems

Experience with protected waveforms and secure modem architectures

Experience reviewing or contributing to DSP implementations in C/C++ or HDL

Active DoD Top Secret clearance

Scheduled Weekly Hours: 40
