Job summary

Longshot Space Technologies is seeking an Avionics Engineer to own the vehicle's electronics stack from architecture through flight. You will lead avionics design, qualification, and integration for a gun-launched hypersonic system.

You will build and test the hardware, work onsite in Alameda, CA, and ensure flight readiness under extreme conditions. This role requires hands-on engineering and bold problem-solving in a fast-paced environment.

Qualifications

• BS in Electrical, Computer, or Electronics Engineering; MS a plus.
• 2+ years designing and delivering electronics or avionics in aerospace/defense/high-reliability environments.
• Strong embedded/firmware experience with C/C++, RTOS or bare-metal, microcontrollers, and board bring-up.

Responsibilities

• Vehicle avionics architecture from concept through CDR, including downlink protocol.
• Design and package flight electronics for gun-launched environments with robust component selection.
• Sensor suite, signal conditioning, data acquisition, and onboard data handling.
• RF/TT&C/communications: Telemetry downlink, antenna integration, link-budget analysis, spectrum coordination.
• Battery chemistry selection and gun-hardened power qualification, plus power distribution and conditioning.
• Flight-termination avionics: support of range-safety qualification.
• Build and own the HIL/SIL test bed for avionics/GNC integration.
• Plan and run 250g in-barrel environmental tests and thermal cycling, interpret data.
• Ground/test instrumentation support for active campaigns with sensors and data acquisition.
• Maintain clear records of avionics architecture, interfaces, and qualification results.

Job description

Longshot Space Technologies is at thecutting edgeof low-cost space access andhypersonics. We are developing a novel space launch system that accelerates mass over a long distance. Using our technology, we plan to provide affordable launch services for satellites, cargo, and future space infrastructure. Our mission is to enable a future where humansdon'tjust reach for thestars, buthold them in the palm of our hands.

Position Overview

We are hiring an Avionics Engineer to own the vehicle's entire electronics stack from architecture through flight.You'llbe the technical authority on everything avionics: flight computer, C&DH, sensor suite, RF and telemetry, power, and flight-termination systems.You'llalso own the HIL/SIL test bed and the environmental and g-load qualification that proves it all survives a gun launch.

With full end-to-end ownership,you'lldesign electronics that withstand 250g and function through hypersonic flight, build and test them yourself, and move at a pace no large aerospace company can match. If you want to get your hands dirty alongside specialized engineers building something thathasn'tbeen done before, this is the role.

• Role Type:Full-time, Exempt
• Location:Onsite in Alameda, CA

Key Responsibilities

• Vehicle avionics architecture:Flight computer / C&DH, avionics stackselection, and downlink protocol, from concept through CDR, qualification, and flight.
• Flight electronics for a gun-launched environment:Board design,componentselection, and packaging that survive in-barrel acceleration and hypersonic flight.
• The vehicle sensor suite and instrumented projectile:Sensorselection, signal conditioning, data acquisition, and onboard data handling.
• RF / TT&C / communications:Telemetry downlink, antenna integration (through the waverider geometry and plasma sheath), link-budget analysis, and FCC / NTIA spectrum coordination.
• The vehicle power system:Battery chemistryselectionand gun-hardened qualification, plus power distribution and conditioning.
• Flight-termination (FTS) avionics:Support of FAA/AST range-safety qualification.
• The HIL/SIL test bed. Build and own the hardware/software-in-the-loop bench for avionics and GNC integration.
• Environmental and g-load qualification:Plan and run 250g in-barrel and thermal-cycling test campaigns; reduce and interpret the data.
• Ground and test instrumentation:Support the active test campaigns (Side Injection, Tonopah) with sensors and data acquisition.
• Technical documentation:Clear,maintainedrecords of avionics architecture, interfaces, and qualification results.

Required Qualifications

• BS in Electrical, Computer, or Electronics Engineering (or a related field); MS a plus. Equivalent hands-on avionics experience will be considered.
• 2+ years designing and delivering electronics or avionics in aerospace, defense, or a comparable high-performance, high-reliability hardware environment.
• Deep embedded/firmware experience. C/C++, RTOS or bare-metal, microcontrollers, and board bring-up.
• Strong PCB design and layout. Schematic capture and multilayer board layout (Altium,KiCad, or equivalent), including design for manufacture.
• Hands-on labproficiency. Soldering, harness/cabling, and bench debug with oscilloscopes, logic analyzers, and power supplies.
• U.S. Person status (U.S. citizen or lawful permanent resident)requiredfor access to export-controlled technical data.
• Able to work onsite in Alameda, CA, with periodic travel to test sites during campaigns.

Preferred Qualifications:

• RF, communications, or telemetry experience. Link-budget analysis, antenna integration, transceivers, and spectrum coordination.
• Power electronics and battery systems, including high-g or gun-hardenedqualification.
• Test instrumentation and data acquisition (DAQ, signal conditioning, LabVIEW or equivalent).
• High-reliability or harsh-environment electronics. Shock, vibration, and high-g environments or space/mil qualification (MIL-STD-810, MIL-STD-461).
• Flight software or GNC integration experience.
• Python or MATLAB for data reduction and test automation.
• 401(k) with company match
• Paid time off and paid sick leave
• 90-day integration period
