The posting

We are looking for a Senior Embedded Wireless Modem Engineer to take ownership of the systems that keep our drones connected, coordinated, and performing flawlessly in the sky.

This is not a narrow, siloed role—you’ll be working across the full stack of wireless communication: from PHY-layer protocol design and signal processing to embedded integration, RF optimization, and real-world validation. Your work will directly impact how hundreds (or thousands) of drones communicate reliably in complex, high-stakes environments.

You’ll be hands-on with everything from modem development and firmware to lab testing and live field deployments—solving tough problems around interference, synchronization, range, and reliability. You’ll also play a key role in getting our systems certified and production-ready, working closely with external labs and internal hardware/software teams.

If you’re excited by building robust wireless systems from the ground up, thrive in fast-paced environments, and want to see your work come to life in large-scale, real-world applications—this role puts you right at the center of it.

As a Sr. Embedded Wireless Modem Engineer, you’ll be responsible for:

  • Owning the design, development, and optimization of radio modems across sub-GHz (868/915 MHz) and 2.4 GHz ISM bands
  • Building robust wireless communication systems using modern RF transceivers (e.g., AT86RF215 and similar)
  • Developing and optimizing PHY-layer protocols, including modulation, synchronization, and timing
  • Designing signal processing algorithms (filtering, timing recovery, detection) for reliable communication
  • Implementing channel coding, error correction, and spread spectrum techniques (FHSS, DSSS)
  • Driving system-level RF performance through link budget, coexistence, and optimization analysis
  • Integrating RF systems with embedded platforms (MCUs) and developing low-level drivers/firmware (C/C++)
  • Debugging and optimizing hardware–firmware interactions in close collaboration with electronics teams
  • Running lab and field testing to validate RF performance in real-world conditions
  • Leading radio certification efforts (CE, FCC, RED, ETSI), including test planning and execution
  • Partnering with external EMC labs and resolving compliance issues through certification cycles
  • Supporting system validation and large-scale deployment testing

Required Qualifications:

  • Degree in Electrical Engineering, Communications Engineering, or a related field
  • Proven experience developing radio modems in ISM bands (sub-GHz and/or 2.4 GHz; LoRa, ZigBee, etc.)
  • Hands-on experience with RF transceivers (e.g., AT86RF215, TI CC13xx/CC26xx, or similar)
  • Strong foundation in digital communication systems (modulation, FEC, synchronization, signal detection)
  • Experience with spread spectrum techniques, particularly FHSS
  • Solid embedded systems experience (C/C++), including low-level driver and firmware development
  • Experience integrating RF ICs with microcontrollers (e.g., STM32 or similar)
  • Proficiency with RF measurement tools (spectrum analyzer, VNA, signal generators, oscilloscopes)
  • Working knowledge of EMC/EMI principles and RF compliance requirements
  • Experience with radio certification (CE, FCC, ETSI) and working with external test labs
  • Familiarity with wireless protocols (e.g., proprietary PHYs, IEEE 802.15.4)
  • Knowledge of PCB design and RF layout best practices
  • Strong problem-solving skills with a structured, independent working style
  • Based in the Munich area and willing to work on-site in Gilching

What we offer:

  • A fun, creative, and highly effective team with a start-up spirit
  • Exciting projects where mechanics, electronics, firmware, and software meet storytelling and arts
  • Real responsibility with no daily micro-management — trust and freedom to do your best work
  • Space to try new things, learn, and grow with us
  • Short decision-making paths, open communication, and strong team spirit

What Defines You:

  • Highly reliable, organized, and execution-focused.
  • Calm under pressure and effective in an onsite operating environment.
  • A clear, proactive communicator who escalates issues early and appropriately.
  • You don’t need to be the “owner of everything” to be high-impact, you like owning your lane and making the overall machine run smoother.
  • You take pride in making complicated work feel simple for the team around you.
  • Team-oriented, humble, and eager to learn.
  • Interested in growing into increased production ownership over time.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
