Flight Software Engineer

Los Angeles, California /
ABL Space Systems /
ABL's Flight Software Engineers are critical to mission success and integral to nearly every subsystem on the launch vehicle ranging from power distribution to propulsion system control.

Solid Flight Software (FSW) Engineers know they are not just programmers, but rather engineers responsible for providing novel solutions in an agile environment while also producing robust, verified code. Good FSW engineers are also capable of bridging disciplines to work with the hardware and systems engineers.


    • Perform and lead the FSW system development, implementation, deployment and testing
    • ‍Gather, define, and document software requirements to meet existing and anticipated needs across the launch vehicle
    • Develop algorithms capable of meeting redundancy requirements
    • Develop, analyze and review data to validate and verify system meets specifications and design requirements
    • Ensure system quality and performance through rigorous software test, verification and validation (V&V) techniques
    • Write test plans and testing cases while leading the execution of unit/integration/systems level V&V
    • Partner with Avionics team to develop hardware requirements (e.g. switches and computers) needed to meet the FSW system level needs

Near Term Responsibilities

    • Work with Ground Software and Integration Checkout teams to stand up racks required to "talk" to the launch vehicle
    • Stand up development integrated test bed or "Hardware in the Loop"(HITL), working with the Avionics, GNC and hardware teams in HITL environment to develop transitions and commands
    • Typical launch vehicle FSW functionality includes:
    • Guidance Navigation Control (GNC)
    • Redundancy and contingency management, capabilities for "Failure Detection Isolation and Recovery" (FDIR)
    • Telemetry packet encoding and decoding
    • HITL simulation both as a development and verification tool
    • Subsystem control (e.g. engine throttle command, open loop events and payload deploy sequencing)

Basic Qualifications

    • B.S. in Computer Science (CS), Computer Engineering (CE), Electrical Engineering (EE), or similar from an accredited university
    • One of the following:
    • ‍2+ years experience in the development of aircraft, missile, spacecraft or similar critical flight software
    • 2+ years experience in game development

Preferred Skills and Requirements

    • Demonstrated skills in applications development in at least one or more high-level programming languages (e.g. C, C++)
    • Proficiency in writing software for UNIX/Linux platform
    • ‍Object-Oriented-Design
    • Simulation and Modeling
    • Capability Maturity Model (CMM)
    • Programming of FPGA or microcontrollers
    • One or more low-level programming languages (e.g. Ladder Diagram, Structured Text, Instruction List)
    • Day of Launch and systems testing support, including vehicle network and switch health verification
    • Demonstrated leadership of or within a small project team either in current role or during project based team in school

What We Look For

    • 1. Critical thinking: ABL engineers understand the "why" behind all design decisions, operational events and test outcomes.  
    • 2. Ability to deal with ambiguity: there is no roadmap and ABL engineers must be comfortable defining their own pathway to an objective. 
    • 3. End-to-end ownership: projects are delivered fully complete and ready for flight; there is no one to pick up the slack of partially complete work.
