## Job description

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.

With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection.

## Overview

We are seeking a GNC Engineer specializing in advanced modeling to develop high-fidelity simulation and analysis capabilities for aerospace vehicle guidance, navigation, and control systems. You will build nonlinear six-degree-of-freedom simulation environments, develop flexible-body and vehicle subsystem models, and validate those models using analytical, test, and flight data.

You will collaborate with GNC, structural, and test engineers to ensure simulation models accurately represent vehicle dynamics and hardware behavior throughout the development lifecycle.

## What You’ll Do

- Develop, maintain, and validate high-fidelity nonlinear six-degree-of-freedom digital twin of the spacecraft bus for design, analysis, and verification.
- Develop flexible-body and structural-dynamics models for integration into vehicle simulations.
- Build and validate physics-based models of vehicle dynamics, sensors, actuators, environmental disturbances, and other subsystems.
- Apply system identification techniques to estimate system parameters and improve model fidelity.
- Derive linear approximate models from nonlinear systems using numerical and analytical techniques.
- Develop simulation capabilities supporting control design, Monte Carlo analysis, software-in-the-loop, and hardware-in-the-loop testing.
- Contribute to model-based software development, verification, documentation, and technical reviews.

Required Qualifications

- Experience developing nonlinear six-degree-of-freedom simulation platforms for aerospace vehicles.
- Experience modeling and validating aerospace vehicle dynamics, sensors, actuators, environmental effects, and other vehicle subsystems.
- Experience developing or integrating flexible-body and structural-dynamics models.
- Strong understanding of rigid-body dynamics, control systems, numerical methods, and linear systems.
- Expertise in system identification and deriving linear approximations of nonlinear dynamic systems.
- Experience with model-based software development and verification processes.
- Strong proficiency in MATLAB, C++, Git, and Linux development environments.

Desired Qualifications

- Master’s degree or Ph.D. in aerospace engineering, controls, robotics, applied mathematics, or a related field.
- Experience developing aerospace vehicle GNC simulations from initial architecture through integrated testing or flight validation.
- Experience with MATLAB/Simulink and automatic code-generation workflows.
- Experience with modal analysis, or flexible-mode identification.
- Experience with software-in-the-loop, or hardware-in-the-loop test environments.
- Experience correlating simulation models with component, subsystem, integrated vehicle, or flight-test data.
- Familiarity with Monte Carlo analysis, uncertainty modeling, sensitivity analysis, continuous integration, and automated testing workflows.

For U.S. Roles: To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3).

For U.K. Roles: To comply with U.K. regulations, this role requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC).

For Canada Roles: Successful candidates must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR.

We celebrate diversity and are committed to creating an inclusive environment for all employees. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.

## About Xona Space Systems

## Company Overview
- **One-liner**: Xona Space Systems is building Pulsar, a high-integrity positioning, navigation, and timing (PNT) constellation in Low Earth Orbit that delivers authenticated, centimeter-accurate services as a resilient alternative to GPS.
- **Entity Type**: Private (Series C – $170M raised ~April 2026)
- **Headquarters**: Burlingame, California, USA (also offices in Montreal, Canada and London, England)
- **Founded**: 2019
- **Founders**: Brian Manning (CEO), Tyler Reid (CTO), Adrien Perkins (VP of Engineering)

## Core Business
- **Primary industries**: Aerospace / Satellite Navigation, Defense & Critical Infrastructure, Autonomous Systems
- **Target customers**: B2B / B2G – enterprise, government, defense, autonomous robotics, construction, industrial IoT, and any application requiring resilient PNT
- **Mission**: “Unlock the potential of tomorrow’s technologies by providing the most robust and accurate navigation and timing services on Earth.”

## Products & Services
- **Pulsar Constellation**: A network of 258 small, software-defined satellites in LEO broadcasting secured, authenticated PNT signals. Offers native user accuracy at centimeter level and is designed to upgrade existing GPS devices via a software update.
- **Pulsar‑Verified Receivers & Simulators**: Certified hardware and test platforms for integrators. Includes reference designs and simulation tools.
- **Time Authentication Service**: A cryptographic layer that validates the origin and integrity of timing signals, providing resilience against spoofing and jamming.

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed (conflicting reports may exist; no official figure available)
- **Key Metric**: Total funding $327.53M (CB Insights); latest Series C closed ~April 2026 (amount $170M)
- **Notable Investors / Partners**: Not publicly disclosed (funding specifics unknown). Key partners include Murata (MOU for LEO navigation in industrial applications), the Government of Canada (R&D collaboration to strengthen timing resilience), and the National Research Council of Canada.
- **Growth Signals**: 
  - Successfully launched Pulsar‑0, the first commercially funded navigation satellite, now in orbit for one year (June 2026).
  - 11+ patents filed (encrypted navigation signals, wireless locating, etc.).
  - Active hiring in Burlingame, Montreal, and London; 828 employees on LinkedIn as of mid‑2026.
  - Collaboration with ISED, NRC, and DRDC to broadcast Canada’s official time signal (UTC(NRC)) from space.

## Competitive Advantages
- **First‑mover with a privately funded navigation satellite** – Pulsar‑0 set a precedent for commercial LEO PNT.
- **Authenticated signals** – Cryptographic security native to the signal provides spoofing/jamming resistance unmatched by traditional GPS.
- **Software‑defined satellites** – Rapid constellation scaling and in‑orbit updates at a fraction of legacy system cost.
- **Multi‑national timing broadcast** – Ability to carry multiple official time standards (US, UK, Canada) on a shared infrastructure, creating sovereign resilience for allies.

## Strategic Focus
- **Constellation deployment** – Scale from prototype (Pulsar‑0) to a full production fleet of 258 satellites.
- **Ecosystem enablement** – Grow partner network of receiver makers, chipset vendors, and integrators (e.g., Murata, government bodies).
- **Geographic expansion** – Establish a strong presence in Canada (Montreal) and the UK (London) while deepening relationships with allied governments.
- **Defense & critical infrastructure** – Pursue contracts that require autonomous, tamper‑proof PNT for military, aviation, and grid timing.

## Why Work Here
- **Impact** – Work on “a generational technology at startup speed”; decisions are pushed to the people closest to the work. Culture of ownership and rapid iteration.
- **Compensation** – Competitive salary, equity (ownership culture), 401(k) / Roth 401(k).
- **Benefits** – 95% of healthcare premiums covered for US employees (50% for dependents); HSA/FSA options; supportive parental leave (equitable); flexible time off.
- **Workplace** – Burlingame office with catered lunches twice a week, snacks, drinks, coffee. Roles also in Montreal and London (hybrid likely per location, but remote‑first not stated).
- **Culture** – Engineering‑driven, fast‑shipping, collaborative; team includes leaders from industry and academia.
