## 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.

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 engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.

Flight Software links together the mechanical, avionics, algorithmic, and embedded worlds to actually make the airplane fly. As a Build Software Engineer, you will own the systems that enable quick and reliable building, testing, and deployment of the entire flight software suite prior to flight. A build software engineer sees lengthy build times as a core developer experience impediment and creates systems to make the whole organization more efficient.

## Responsibilities

In your role as Build Software Engineer, you will shape the build and continuous integration design for C++ and Rust software products both on-premise and in the cloud. You will also lead optimization of that infrastructure to ensure all software builds supporting flight are fast and repeatable across environments. You will work in a highly collaborative environment and coordinate with multiple stakeholders across engineering and IT functions.

## Basic Success Criteria

- Bachelor’s degree in Computer Science, Computer Engineering, or equivalent experience
- 5+ years of experience large scale or mission critical environments implementing methodologies of continuous build, integration, and delivery (CI / CD)
- 5+ years experience in C++
- 2+ years of professional experience managing a modern C++ build system (Cmake, Bazel, ninja)
- Experience with release automation and configuration management tools

## Preferred Success Criteria

- Experience with performance optimization such as identifying and resolving bottlenecks in Linux and AWS, optimizing containers to enable efficient scaling, and lowering costs
- Experience with Sonatype Nexus or similar artifact management systems
- 1+ years experience in Rust
- Experience working with AWS in a production environment

As a Build Software Engineer, you will be part of the Platform Software team. The Platform Software team is responsible for providing the low level embedded software and build infrastructure necessary to enable the development, test, and deployment of our autonomous aircraft software. This infrastructure consists of everything from multi-language build systems, hardware-in-the-loop (HITL) testbed configuration, continuous integration pipelines, and cloud-based simulation container deployments. You will drive the optimization of our current infrastructure tooling as well as designing and developing the future of our team’s development pipeline. You will help develop and maintain essential tools that enable developers at Reliable Robotics to deliver software products that are safe, successful, and meet certification requirements.

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.

## 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
