The Mission

European security is at an inflection point. The war in Ukraine has proven that unmanned systems are the decisive factor on the modern battlefield. But these platforms are only as effective as the data links that control them. That's where we come in: we build resilient, mass-deployable SDRs (Software Defined Radios).

We're looking for a Technical Integration & Operations Engineer who understands that a product isn't "done" until it works flawlessly in the hands of the end user. You are the last line of defence for our hardware's reliability — and the technical face of ZeroPhase in the field.

The Role

This is a high-impact, hands-on position. You are not a lab engineer who occasionally goes to the field. You are a field engineer who can hold their own in the lab. You own our SDRs end-to-end — from the moment they leave production to the moment they are successfully integrated into the customer's platform.

You are ZeroPhase's technical face with the customer. You don't just execute test protocols — you design the entire test ecosystem. You automate manual processes, solve hardware problems, and travel to customer sites to ensure our technology performs under real-world conditions.

Core Responsibilities

• Field Integration: Integrate our data links into customer platforms on-site — drone hangars, test ranges, and operational environments. You are the "fixer" who makes it work in the field.

• Test Protocol Design & QA: Develop and document rigorous test procedures for our SDRs. You define what "mission-ready" actually means.

• Automation & Scripting Build the software scaffolding (Python/Bash) to automate flashing, configuration, and hardware validation. Scale is the goal — manual clicks are the enemy.

• Hardware Troubleshooting You are the first responder when hardware problems arise. Armed with an oscilloscope, multimeter, and spectrum analyser, you diagnose failures and work closely with R&D to implement solutions.

• Feedback Loop You are the eyes and ears of the engineering team. You translate field failures and customer requirements into technical specifications for the next hardware iteration.

Qualifications

• Technical expertise: You understand RF fundamentals — gain, interference, SNR — and can read a waterfall diagram. You're at home in a Linux environment.

• Scripting skills: You can write clean, functional code in Python or Bash to automate repetitive tasks.

• Hardware intuition: You have a feel for hardware. You can spot a cold solder joint, read a schematic, and aren't afraid to pick up a soldering iron.

• High agency: You don't wait for a manual — you write one. If a field integration fails, you stay until the link is up.

• Field DNA: You're as comfortable in a cleanroom as on a muddy test range. You thrive under pressure when technology needs to work right now.

• Communication: Business-fluent English (German is a must). You can explain complex RF problems without resorting to jargon.

Nice to Have

• Experience with SDR platforms (GNU Radio, USRP, LimeSDR or similar)

• Background in contested RF environments — military or electronic warfare adjacent

• Drone / UAS platform experience at the systems level

• Field deployment experience in operational environments

What This Role Offers

We're looking for a force multiplier — someone who cares more about a working product than a perfect simulation. This is not a conventional 9-to-5 office job. It's the opportunity to help build the technical backbone of a modern defence company. If seeing your work deployed in critical missions is what drives you, this is the role for you.
