GNC Engineer - Hybrid (TS/SCI Clearance)

Title

GNC Engineer - Hybrid (TS/SCI Clearance) Belong. Connect. Grow. with KBR!

Around here, we define the future.

We are a company of innovators, thinkers, creators, explorers, volunteers, and dreamers. But we all share one goal: to improve the world responsibly and safely.

THIS POSITION IS CONTINGENT UPON CONTRACT AWARD

We are seeking a GNC Engineer to support the design, development, testing, and real-time operation of advanced aerospace systems. This role bridges engineering development and flight/operational execution, requiring strong technical depth, sound judgment under pressure, and the ability to translate complex system behavior into actionable decisions.

The ideal candidate brings experience across flight dynamics, control systems, software interaction, and operational environments.

This is a remote position with limited, business-need driven travel to onsite locations.

Key Responsibilities

GNC System Development & Integration

Support design, analysis, and verification of guidance, navigation, and control algorithms and architecture

Review and guide flight software design to improve system performance, robustness, and operability

Evaluate system behavior across full mission phases (e.g., ascent, on-orbit, entry, proximity operations)

Operational Readiness & Real-Time Support

Develop and execute operational concepts for GNC systems in mission or test environments

Monitor vehicle performance and make time-critical recommendations during dynamic operations

Support anomaly resolution, fault response strategies, and contingency planning

Requirements, Tools & Procedures

Define system and console requirements for monitoring and commanding GNC subsystems

Develop operator displays, telemetry utilization strategies, and command interfaces

Maintain flight rules, procedures, and operational documentation

Testing & Validation

Support system-level testing (integrated labs, simulations, hardware-in-the-loop environments)

Participate in verification of telemetry, command pathways, and system responses

Contribute to development and validation of contingency commanding capabilities

Required Qualifications

TS/SCI Clearance

Bachelor’s degree in aerospace engineering, Mechanical Engineering, or related field (advanced degree preferred) and 10+ years of experience

Strong foundation in

Orbital mechanics / astrodynamics

Control systems and state estimation

Guidance algorithms and vehicle dynamics

Experience working with

Flight software or embedded systems

Real-time or near-real-time operational environments

Telemetry analysis and command/response systems

Demonstrated ability to

Operate effectively under pressure and make timely, sound decisions

Communicate complex technical issues clearly and concisely

Work across multidisciplinary teams

Must be a U.S Citizen

Preferred Qualifications

Experience supporting mission operations or system operations in a control center or similar environment

Background in anomaly resolution, fault detection/isolation/recovery (FDIR), and contingency operations

Familiarity with simulation environments, integrated test labs, or hardware/software validation

Experience developing procedures, flight rules, or operator tools

Prior experience training or certifying personnel in technical or operational roles

What Sets a Strong Candidate Apart

Demonstrated ownership of end-to-end GNC capabilities (not just analysis, but how the system is used )

Ability to connect engineering design decisions to real-world operational impacts

Proven performance in high-stakes, time-critical environments

Strong judgment, accountability, and credibility with both engineers and operators

Comfort operating in “gray space” where processes aren’t fully defined

Basic Compensation

Jobs on this contract range from $133,900 - $200,800.

The offered rate will be based on the position, contract affordability, the selected candidate’s working location, knowledge, skills, abilities, experience, and in consideration of internal parity.

Additional Compensation

KBR may offer bonuses, commissions, or other forms of compensation to certain job titles or levels, per internal policy or contractual designation. Additional compensation may be in the form of sign on bonus, relocation benefits, short-term incentives, long-term incentives, or discretionary payments for exceptional performance.
