Aerofex | Senior Flight Software Integration Engineer (Ardupilot / Simulink) | Remote / Los Angeles | Contract

Aerofex is a rapidly-growing aerospace startup developing next-generation thrust vectoring and VTOL propulsion technology for manned and unmanned platforms. We are seeking an experienced engineer to support the migration of an existing flight-control implementation from a flight-verified Simulink-like development environment into an ArduPilot-based production implementation.

This is a 1-2 month contract position, with potential for future full-time work. The primary task is to create a custom ArduPilot airframe configuration for a (slightly) nonstandard vehicle. This work will focus on actuator/output mixing, PWM output expansion, firmware integration, and hardware-level debugging on a Pixhawk-based flight controller. A successful candidate will have worked closely on a similar task and is very familiar with Ardupilot.

We ship OSS self-hosted and have a live cloud SaaS: https://betterdb.com/login In the last two months we've averaged more than one release per week across multiple products and channels.

Just email kristiyan@betterdb.com with a bit about yourself and why this is interesting to you. I reply to everyone. It might take a day or two given volume, but you'll hear back.

Cologne, Germany | UMH | Product Engineer | Full-time | 55 - 85k EUR | ONSITE (part remote)

Hi, Alex and Jeremy here from UMH.

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.

What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.

Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.
