How much do estimation engineer jobs pay per hour?

As of Sep 14, 2026, the average hourly pay for estimation engineer in California is $55.26, according to ZipRecruiter salary data. Most workers in this role earn between $39.62 and $73.56 per hour, depending on experience, location, and employer.

What is an estimation engineer?

Estimation Engineers are professionals responsible for calculating the costs, resources, and time required for engineering projects. They analyze project specifications, collaborate with other departments, and use specialized software to prepare detailed estimates. Their work helps companies make informed decisions when bidding on projects and planning budgets. Estimation Engineers play a vital role in ensuring that projects are financially viable and delivered within budget constraints.

How does an estimation engineer typically collaborate with other departments during a project bid?

Estimation Engineers frequently work closely with departments such as procurement, engineering, and project management to gather accurate cost data, review technical specifications, and ensure all aspects of the bid are covered. This collaboration often involves regular meetings, document reviews, and clarifications to align on project requirements and constraints. Effective teamwork is essential, as Estimation Engineers rely on input from various specialists to produce precise and competitive estimates. Strong communication and coordination skills are key to navigating these interactions and delivering successful proposals.

What are the key skills and qualifications needed to thrive as an estimation engineer, and why are they important?

To thrive as an Estimation Engineer, you need strong analytical abilities, attention to detail, and a background in engineering or construction, often supported by a relevant degree. Familiarity with estimation software like AutoCAD, CostX, or Microsoft Excel, and sometimes certifications like AACE or PMP, are commonly required. Excellent communication, problem-solving skills, and teamwork help you collaborate effectively with project managers and clients. These skills ensure accurate cost assessments, minimize project risks, and support successful project planning and execution.

What is the difference between Estimation Engineer vs Cost Engineer?

AspectEstimation EngineerCost Engineer
CredentialsBachelor's in Engineering, Construction Management, or related field; certifications like AACE or PMI often preferredBachelor's in Engineering, Construction Management, or related field; certifications like AACE or PMI often preferred
Work EnvironmentPre-construction phase, project bidding, proposal developmentProject execution, cost control, budgeting, and financial analysis
Industry UsageConstruction, engineering, manufacturingConstruction, engineering, infrastructure projects

Estimation Engineers primarily focus on preparing cost estimates during project bidding and planning stages, while Cost Engineers monitor and control project costs during execution. Both roles require similar credentials and often work within the same industries, but their responsibilities differ in project lifecycle stages.

Job description

Senior Guidance, Navigation & Control (GNC) Engineer Spacecraft Autonomy

Carson, Ca
$225,000 $300,000


Build the Brain That Flies the Spacecraft.

We re looking for an exceptional GNC Engineer to develop the flight-critical algorithms behind the next generation of autonomous spacecraft.


This isn't a role where your work ends in MATLAB.


You'll own GNC technology from simulation through embedded flight software and hardware-in-the-loop testing ultimately helping autonomous spacecraft rendezvous, maneuver, navigate, and operate safely around other objects in orbit.


If you've taken GNC algorithms beyond simulation and into real flight hardware, we want to talk to you.


What You'll Work On

You'll architect, develop, integrate, and validate GNC systems supporting:




  • Autonomous rendezvous & proximity operations (RPO)




  • Formation flying and precision orbital maneuvering




  • Attitude Determination & Control Systems (ADCS)




  • Orbit determination and relative navigation




  • State estimation and sensor fusion




  • Autonomous trajectory planning and control




  • Flight-critical embedded software




You'll work with IMUs, GPS, star trackers, LiDAR, optical navigation sensors, reaction wheels, thrusters, and other spacecraft systems to answer three critical questions:


Where are we? Where do we need to go? How do we get there?


What You'll Be Doing


  • Design and tune spacecraft guidance, navigation, and control algorithms




  • Develop Kalman filtering, state estimation, and sensor-fusion solutions




  • Model orbital dynamics, relative motion, trajectories, and environmental disturbances




  • Develop GNC for autonomous RPO and formation flying




  • Design and validate ADCS and orbit-determination systems




  • Transition algorithms from MATLAB/Simulink and Python into embedded C/C++ flight software




  • Integrate and test algorithms in HIL and flight-like environments




  • Develop 6DOF simulations and conduct Monte Carlo analysis




  • Validate performance under uncertainty, degraded sensors, and failure scenarios




  • Work directly with systems, avionics, software, and autonomy engineers




  • Own your work from initial concept through mission-ready implementation




What We're Looking For


  • 5+ years of GNC experience involving spacecraft, launch vehicles, missiles, autonomous vehicles, or similar high-performance systems




  • B.S. or M.S. in Aerospace, Mechanical, Electrical Engineering, or related discipline




  • Strong background in control theory, orbital mechanics, and state estimation




  • Experience with Kalman filtering, EKF/UKF, sensor fusion, or orbit determination




  • MATLAB/Simulink and Python proficiency




  • C/C++ experience




  • Experience with HIL, embedded flight software, or flight-like testing




  • Strong understanding of spacecraft dynamics and control




The Experience That Will Really Get Our Attention

You've taken an algorithm off the whiteboard, proved it in simulation, implemented it in flight software, tested it against hardware and ideally watched it perform in an operational environment.


Experience with any of the following is especially valuable:


RPO Rendezvous Proximity Operations Formation Flying ADCS Astrodynamics Optical Navigation LiDAR Star Trackers Reaction Wheels 6DOF HIL Monte Carlo LQR MPC Quaternions STK GMAT FreeFlyer Basilisk


Why This Opportunity?

You'll join a small, high-impact engineering organization developing autonomous spacecraft technology for national security missions.


You won't own one tiny piece of a massive program.


You'll have meaningful technical ownership across the lifecycle architecture, algorithms, simulation, software integration, hardware testing, and ultimately flight.


The compensation reflects the caliber of engineer we're looking for:


$220,000 $300,000


Important Requirements

This position is 100% on-site in Carson, California. Remote and hybrid arrangements are not available.


Candidates must be U.S. Citizens and must have or be capable of obtaining a TS/SCI security clearance.


Interested?

If you're a GNC engineer who wants to build autonomous spacecraft instead of spending your career watching simulations run, let's talk.


Please send your resume to
