- **Apply:** https://jobs.ashbyhq.com/reliable-robotics/b06d3f92-ccad-47ce-b5ae-dd97b80f3270/application

**Skills:** C, C++, Embedded Systems, Bare Metal Programming, Unit Testing, Computer Architecture, Operating Systems, Networking, DO-178C, Safety Critical Applications Software

> Develop deterministic C++ software for embedded aircraft systems, integrating with sensors and control systems to automate flight operations. The role involves driving requirements, implementing unit tests, and collaborating with flight hardware and testing teams in a safety-critical environment.

## 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 Software Engineer at Reliable Robotics, you will automate the operation of highly complex aircraft systems. Our Flight Software teams are deeply involved in all aspects of the development and certification of the Reliable Robotics autonomy stack, and play a central role in bringing our aircraft to life.

## Responsibilities

In your role as Flight Software Engineer, you will develop highly deterministic C++ software in a bare metal environment that works with sensors & control systems, robustly handles system faults, and integrates with other vehicle subsystems. You'll drive requirements and implement excellent unit tests. You'll also have the opportunity to work directly with flight hardware in the lab and on the plane, plan flight testing, and watch your code fly an aircraft.

## Basic Success Criteria

- Bachelor's Degree in Computer Science, Aerospace or equivalent experience
- 7+ years of professional experience with C or C++
- Professional experience developing software for embedded or high performance applications
- Ability to work in a self-directed manner in a fast-paced environment

## Preferred Criteria

- Thorough understanding of computer architecture, operating systems and networking
- Experience with DO-178C
- Experience developing software for safety critical applications
- Excellent written and verbal communication skills

Flight Software links together the mechanical, avionics, algorithmic, and embedded worlds to actually make the airplane fly. The core nature of the role offers the opportunity to interact with teams and components across the entire automated aircraft and to specialize in the areas most exciting to you.

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.

## 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
