Embedded Rust Engineer

Location: On-site in Wessling, Bavaria, Germany

Company

hirify.global develops and produces small unmanned aerial systems, including electric vertical take-off and landing aircraft with edge computing and real-time AI-powered data processing for defence, security, and public-sector customers.

What you will do

• Design and maintain the embedded Rust architecture and production-grade no_std firmware for an STM32-based autopilot.
• Implement and maintain drivers for SPI, I2C, UART, ARINC 825, USB, Ethernet, DShot, ADC, and other peripherals.
• Build asynchronous and real-time components using interrupts, DMA, timers, and carefully designed concurrency.
• Measure end-to-end latency, profile hot paths, and optimize CPU usage, memory footprint, data movement, jitter, and deadline compliance.
• Debug firmware and electronics at register and signal level using hardware probes, schematics, and reference manuals.
• Integrate flight-control and navigation algorithms and validate timing, fault handling, and performance on hardware and in flight.

Requirements

• Excellent Rust skills, including ownership, lifetimes, traits, generics, error handling, and zero-cost abstractions.
• Hands-on experience with embedded or no_std Rust, embedded-hal, Embassy or RTIC, probe-rs, cargo-embed, and cargo-flash.
• Experience developing firmware for STM32 or comparable ARM Cortex-M microcontrollers.
• Deep understanding of memory-mapped peripherals, interrupts, DMA, timers, scheduling, and MCU concurrency.
• Experience with SPI, I2C, UART, CAN/CAN-FD, low-level debugging, embedded reliability, fault tolerance, and safety-critical principles.
• Strong Git workflows and a performance-oriented approach to latency, jitter, worst-case execution time, CPU load, and memory use.

Nice to have

• Experience with UAVs, drones, robotics, or flight controllers such as PX4, ArduPilot, or Betaflight.
• Familiarity with MAVLink or functional safety.

Culture & Benefits

• Flexible, trust-based working hours with responsibility for work-life balance.
• One flexible remote workday per week.
• Company pension scheme and subsidized EGYM Wellpass membership.
• Bike leasing, corporate discounts, sponsored daily lunch budget, and employee events.
• Company shuttle service from Laim in Munich to the Wessling location.
• Inclusive workplace focused on diversity, collaboration, and technological excellence.
