What Avionyx does

Avionyx is an aerospace engineering services firm founded in 1989 in Florida that relocated all operations to Costa Rica (America Free Zone, San José / Heredia) by 2008. It provides full life-cycle avionics software and hardware engineering, verification, and certification services centered on the safety-critical compliance standards DO-178C, DO-254, DO-278A, and DO-330. Its clients are aerospace manufacturers—including electric aircraft, eVTOL, unmanned aerial systems, and traditional fixed- and rotary-wing developers—that require Design Assurance Level A compliance and FAA certification support. The company is AS-9100D certified (0 findings since 2020) and holds RTCA and NBAA memberships.

The core offering is a suite of compliance-driven professional services: DO-178C software development/verification, DO-254 airborne electronic hardware assurance (FPGAs, ASICs), DO-278A CNS system assurance, DO-330 tool qualification, and extended engineering design services (mechanical design, drafting, tool design). Avionyx has also built proprietary tooling, including PolaTEST (automated testing software for power-delivery verification), custom instrumented boards, and a portfolio of Siemens Polarion ALM extensions (Document Reviews, Log Viewer, Simple Traceability Diagrams, and customization). It became a certified Siemens Technology Partner in 2024 and positions itself as an early adopter of AI for software verification.

Avionyx monetizes through a B2B professional-services model—staff augmentation, project-based consulting, and turn-key certification solutions—delivered via direct enterprise field sales ([email protected]) primarily across the Americas. Pricing is quote-based and not publicly disclosed. Its differentiation rests on 35+ years of specialized regulatory expertise (including FAA Designated Engineering Representative capabilities) and a near-shore Costa Rica cost structure with US time-zone alignment. In 2022 the company was acquired by Joby Aviation Inc. (NYSE: JOBY) to strengthen Joby's FAA certification efforts; Avionyx now provides extensive back-end shared services to the broader Joby enterprise while continuing to serve external aerospace clients. As of 2025, approximately 200 employees support both Joby and Avionyx customers.
