## Job description

We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.

As a Flight Navigation Engineer at Reliable Robotics, you will be part of the Guidance, Navigation and Control Team. You will contribute to the navigation system design, implementation, and testing, and your work will enable the integration of uncrewed aircraft into the National Airspace System.

## Responsibilities

- Define navigation system requirements in collaboration with internal and external stakeholders
- Analyze, source, and select sensor solutions for use in the navigation system
- Develop sensor models in simulation for evaluation of the navigation system
- Implement state estimation algorithms in flight software
- Establish test methods to ensure compliance with requirements, best practices, and regulatory standards
- Evaluate the navigation system via simulation, hardware-in-loop, and flight test cases

## Basic Success Criteria

- BS in aerospace engineering, electrical engineering, computer science, or similar advanced degree
- Technical expertise in one of the following areas: Kalman filtering; GNSS navigation; inertial navigation; or alternative navigation technologies
- 3+ years of professional experience developing and testing navigation algorithms
- Professional experience with developing C/C++ flight software and Python data reduction & analysis
- Excellent written and verbal communication skills

## Preferred Criteria

- MS in aerospace engineering, electrical engineering, computer science, or similar advanced degree
- Technical expertise in one of the following areas: probability theory; fault detection and exclusion (FDE); sensor error/noise modeling; or GPS-denied navigation
- Experience developing software for safety critical applications
- Experience with navigation system certification

We are building high-integrity, safety-critical systems for automated flight, and your role is critical to what we do at Reliable Robotics. With the support of the whole team, you will contribute to a novel navigation system that drives our mission forward.

Must be willing to travel 10% of the time. This position is based at our facility in Mountain View, California.

This position requires access to information that is subject to U.S. export controls. An offer of employment will be contingent upon the applicant’s capacity to perform in compliance with U.S. export control laws. All applicants are asked to provide documentation that legally establishes status as a U.S. person or non-U.S. person (and nationalities in the case of a non-U.S. person). Where the applicant is not a U.S. person, meaning not a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident, (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, or not otherwise permitted to access the export-controlled technology without U.S. government authorization, the Company reserves the right not to apply for an export license for such applicants whose access to export-controlled technology or software source code requires authorization and may decline to proceed with the application process and any offer of employment on that basis. At Reliable Robotics, our goal is to be a diverse and inclusive workforce. As an Equal Opportunity Employer, we do not discriminate on the basis of race, religion, color, creed, ancestry, sex, gender (including pregnancy, childbirth, breastfeeding, or related medical conditions), gender identity, gender expression, sexual orientation, age, non-disqualifying physical or mental disability or medical conditions, national origin, military or veteran status, genetic information, marital status, or any other basis covered by applicable law.

If you require reasonable accommodation in completing an application, interviewing, completing any pre-employment testing, or otherwise participating in the employee selection process, please direct your inquiries to work@reliable.co

## About Reliable Robotics Corporation

## Company Overview
- **One-liner**: Reliable Robotics is building a certifiable autonomous flight system to make air transportation safer, more available, and more affordable for cargo and passenger aircraft.
- **Entity Type**: Private (Series D)
- **Headquarters**: Mountain View, California, United States
- **Founded**: 2017
- **Founders**: Robert Rose (CEO) and Juerg Frefel (CTO)

## Core Business
- **Primary Industry**: Airlines and Aviation / Autonomous Flight Systems
- **Target Customers**: Cargo operators (Part 23), passenger airlines (Part 25), and government/military logistics providers (B2B, Enterprise)
- **Mission / Purpose**: “Advanced automation will make aircraft safer, more available, more affordable and fundamentally transformative to the way goods and people move around the planet.”

## Products & Services
- **Reliable Autonomy System**: A fully integrated, FAA‑certifiable system that enables gate‑to‑gate autonomous operation – including auto‑taxi, auto‑takeoff, en‑route flight, auto‑landing, and detect‑and‑avoid. Designed initially for Part 23 cargo aircraft and expanding to Part 25 passenger jets. (Type: Hardware + Software + Service)

## Market Standing
- **Valuation / Market Cap**: Not disclosed (private company)
- **Key Metric**: Total funding — $330.6 M (8 rounds, per LinkedIn/Craft) or $303.1 M (per CBInsights); conflicting reports. Last round: Series D (led by Nimble Partners, with participation from Coatue, Lightspeed, UP Partners, and others).
- **Notable Investors / Partners**: Coatue, Lightspeed Venture Partners, UP Partners, Pathbreaker Ventures, Presidio Ventures, Nimble Partners. FAA (testing partner).
- **Growth Signals**: Headcount of 154 (up ~55% YoY), 65 active job postings (+44% YoY), FAA‑contracted flight testing of its detect‑and‑avoid system, and announced completion of the first FAA‑certifiable system for fully automated operation.

## Competitive Advantages
- **Certification‑forward approach**: First system to achieve FAA certifiability for fully automated aircraft operation, a critical regulatory moat.
- **End‑to‑end capability**: Covers all phases of flight (taxi, takeoff, route, landing, detect‑and‑avoid), reducing integration risk for operators.
- **Top‑tier engineering talent**: Heavily recruits from SpaceX, NASA, Lockheed Martin, and Virgin Orbit, indicating deep aerospace expertise.

## Strategic Focus
- **Commercialization for Part 23 cargo**: Near‑term priority to bring the system to market for cargo operators, leveraging existing FAA testing.
- **Expansion to Part 25 passenger aircraft**: Long‑term roadmap to serve the passenger airline market.
- **Scaling the engineering team**: Growing headcount rapidly (54.7% YoY) to accelerate certification and deployment.

## Why Work Here
- **Hybrid workspace**: Employees work a combination of remote and on‑site at the Mountain View headquarters; some roles are in‑office or flexible.
- **Engineering‑centric culture**: 48% of employees are in technical roles; strong talent pipeline from SpaceX, NASA, and top aerospace firms.
- **Employee rating**: 4.2/5 on Built In (based on 19 reviews), with top marks for Work‑Life (4.2) and Culture (4.1).
