About the role

Key responsibilities & impact

Own the architecture, development, and sustainment of real-time I/O software and telemetry infrastructure for aircraft integration benches and simulation environments
Develop modern C++ software on embedded Linux targets to interface with avionics hardware, manage periodic execution and watchdogs, and integrate generated aircraft simulation models
Develop and maintain hardware abstraction layers using UEI PowerDNA equipment, vendor SDKs, low-level I/O APIs, and device drivers
Integrate ARINC 429, CAN, serial, and discrete I/O using aircraft interface control documents
Develop and maintain asynchronous Rust services that ingest telemetry sources, synchronize and order samples, and stream data to displays and recording systems
Implement binary protocols and network interfaces using UDP, TCP, and ZeroMQ
Build timestamp alignment, session recording, data retrieval, and simulation replay capabilities
Maintain cross-compilation, packaging, and deployment workflows for ARM Linux targets and Linux hosts using Yocto SDKs, CMake, Debian packages, systemd, Docker, and Docker Compose
Establish automated verification through unit tests, hardware integration tests, parser fuzzing, and Python-based smoke tests and tooling
Partner with avionics, aircraft software, flight dynamics, and flight test engineers to reproduce aircraft integration conditions and resolve software/hardware issues

Requirements

What you’ll need

Strong proficiency in modern C++, including resource management, concurrency, error handling, and maintainable systems software design
Experience developing timing-sensitive software on Linux, including fixed-period execution, watchdogs, thread synchronization, and reliable startup and shutdown
Deep familiarity with Linux host and embedded systems, including services, permissions, networking, software builds, deployment, and system-level diagnostics
Experience integrating avionics or comparable hardware interfaces, including ARINC 429, and ability to interpret and implement interface control documents
Experience developing binary serializers and parsers, including byte order, framing, validation, malformed inputs, and protocol compatibility
Strong understanding of UDP/TCP networking and asynchronous data pipelines, including buffering, packet loss, ordering, backpressure, and connection management
Experience with embedded Linux cross-compilation and deployment using vendor SDKs and build systems such as CMake
Proficiency in Python for engineering tools, test automation, and data-processing workflows
Experience developing Rust services, or substantial experience with asynchronous systems programming and ability to become productive in Rust
Experience with automated testing, continuous integration, Git-based version control and code review, and Jira or comparable issue tracking
Demonstrated ability to own an end-to-end system, lead technical decisions, and troubleshoot directly with physical hardware
Ability to work regularly onsite in the Boston lab
Direct experience with UEI PowerDNA/PDNA SDKs or comparable platforms, async Rust, ARINC 429/CAN/MIL-STD-1553/RS-232/RS-422, IRIG/NTP, flight-test telemetry, Yocto/ARM/Debian/systemd, flight dynamics, GoogleTest/pytest, CI/CD, Docker, S3, REST APIs, JSON schema, Cap’n Proto, SQL, or related tools is nice to have
All job offers are contingent upon passing background and reference checks
Must be authorized to work in the United States without visa sponsorship now or in the future
